The agriculture industry is widely believed to be essential to the nation's long-term growth and prosperity. In many ways, including via enhanced food security, employment, and economic growth, the agricultural sector as a whole and fisheries in particular have made significant contributions to enhancing people's health and well-being. A variety of measures may be used to determine the financial health of the fish farms. The purpose of this study was to estimate the financial viability of fish pond farming and to ascertain its advantages and disadvantages. From the Taltoli upazila in the Barguna area, sixty pond fish breeders were randomly selected. These figures allow us to calculate the gross cost of producing pond fish per hectare to be 1378806 BDT, the gross return to be 2125023 BDT, and the net return to be 746217 BDT. The findings of this study proved that pond fish farming was a profitable endeavor in the region that was being studied. The Cobb-Douglas production function was further employed in order to better comprehend the part that each variable in the production of pond fish plays. The majority of the taken into account factors were demonstrated to have a considerable impact on fish productivity. The returns on pond fish production were positively and statistically significantly impacted by four of the six parameters studied. To improve the management and cultivation of pond fish farming, certain recommendations were made. Asian J. Med. Biol. Res. 2022, 8 (4), 240-250

The main area of development of aquaculture in our country today is pond fish farming, which has a long history of development. Pike is a very valuable species in aquaculture, especially for pond culture in polyculture with carp or pasture aquaculture in lakes. Ukraine has significant resource potential for growing marketable pond fish in farms, as a promising form of production organization. The direction of the development of polyculture in fish farming is a promising direction that develops and is effectively implemented in fish farming every year. Polyculture is based on such main objects of aquaculture as carp and herbivorous fish, as well as additional ones – pike, catfish, zander, tench, crucian carp. Currently, special attention in the development of polyculture is directed to the cultivation of pike. Stocking with pike brings not only additional fish productivity due to the realization of growth potential, eating low-value fish species, acting as a biomeliotrator, but also stimulates the growth of the main fish species. Using a rational ecosystem of ponds with the targeted formation of its trophic links under optimal polyculture, it is possible to obtain natural fish productivity in the grazing form of fish farming from 1 to 1.6 t/ha and more. This summer's marketable pike can be and expediently grown both in relatively small and sufficiently large feeding carp ponds, provided that trash fish are distributed in them, and these ponds must also be drainable. The cultivation of the main objects of fish farming is improved thanks to the introduction of pike into polyculture. It eats low-value fish, which contributes to better growth productivity of carp and herbivorous fish. In addition, the pike itself is a valuable object of fishing, which brings the conditions of growing commercial fish in farms closer to natural ones. The highest efficiency can be achieved thanks to the exact selection of technological parameters of the entire fish farming process. Numerous factors must be taken into account here: the temperature regime of the reservoir, dissolved substances, the development of the natural fodder base, the optimal density of fish planting, the rational ratio of species in polyculture, etc. Thus, given the appropriate parameters, this technology ensures greater efficiency of the industry and creates prerequisites for increasing its competitiveness.

Full textAbstract:
The U.S. catfish industry is seeking production systems that are efficient, intensive, and profitable. Growing foodsize and stocker-sized fish in the same pond is attractive as it is often difficult to obtain larger-sized stockers early each year. This case study evaluated the performance and economics of producing foodsize hybrid catfish and stocker-sized fingerlings in in-pond raceway systems (IPRS) placed into four 0.4 ha ponds. Growout raceways (RW1/RW2) in ponds 1 and 2 were 63 m3, and 45 m3 in ponds 3 and 4 (RW3/RW4). Each pond had one (14 m3) stocker unit raceway and a 5 HP of aeration that maintained adequate dissolved oxygen levels. Average growout production was 12,050 kg/ha in 63 m3 raceways and 12,078 kg/ha in 45 m3 raceways (228 days of production) and achieved harvest weights ranging from 564 to 661 g. The raceway stocker unit had production yields ranging from 3537 to 4388 kg/ha (143 days of production) and achieved harvest weights ranging from 123 to 234 g. Stocker units in ponds 1 and 2 generated 8540 stocker–fingerlings (21,102 fingerlings/ha) and units in ponds 3 and 4 generated 7954 fingerlings (19,654 fingerlings/ha). An investment of USD 39,996 was needed for ponds 1 and 2 and USD 21,196 for ponds 3 and 4. When scenarios were analyzed financially, positive financial net returns occurred when farm level investment decreased, leading to reduced payback periods, increased net present values, and higher internal rates of return. IPRS used stocker units to culture fingerlings for future stocking of foodsize fish. IPRS provided good inventory control, and high production yields compared to traditional pond culture of catfish.

The analysis of the fishery companies of the republic shows that the main drawback in the fishing industry is the small volume of mass rearing of fish fry and the ineffective use of artificial groundwater reservoirs both – built in the 60-80s of the last century and those currently under construction. Due to the inappropriate size of the surface of these lakes, about 50-100 hectares, and insufficient depth in the ponds, small quantities of carp (2000-3000 units) are bred, large-scale repairs are being carried out, and the fish catch per pond with an area of 1.0 hectares is 1,0-3.0 tons, which, in turn, requires a large amount of water, mineral fertilizers and animal feed. The Innovative Fishery Center under the Fergana State University explores favorable hydro biological conditions for intensive fish farming, with an account of the climate of the republic, without the use of aerators, by organizing the circulation of water in the pond water, in order to provide fish bred in the reservoir with a sufficient amount of oxygen, considering the insufficient surface of the area (0.5-1 hectares – ponds with artificial soil, up to 1.5 hectares – natural reservoirs). As a result of carp care in poly culture, fish productivity is increased by 3-4 times as compared to the method of extensive fish farming.

Full textAbstract:
This paper explores the decline of commercial fishing on the upper Mississippi River. For much of the 20th century fishing provided work for many in river communities and an important buffer against fluctuations in the regional economy. In the late 1960s the introduction of pond-raised catfish from newly created fish farms in the southern United States created a source of uniform, mild-flavored, and untainted fish that satisfied the preferences of both the food industry and consumers. Demand for river fish, in particular catfish, collapsed. Today fish are plentiful in the Mississippi but low prices offer little incentive to independent fishers. Some fish processors, faced with declining local demand, have stepped up sales of river fish to markets as far away as New York. Other processors have opted not to fight the fish-farming industry and now distribute pond-raised catfish. This paper explores the complex social and economic forces that have reshaped local economies and the ecology of the river itself.

In addition to producing fish, freshwater fish pond farms preserve biodiversity, serve as important aquatic ecosystems, and enhance and maintain of the quality of the ecosystem, provide services for a range of recreational activities, are crucial to the management of water and landscape, and aid in the preservation of cultural heritage. the evaluation of reviews of the literature from all pertinent sources. Review findings indicated that high-value species are the most common fish farmed in Cambodia's ponds and cages such as snakehead (Channa micropeltes, Channa striata), Pangasius catfish (Pangasianodon hypophthalmus) and hybrid catfish (Clarias batrachus and C. gariepinus) and introduced fishes such as Nile tilapia (Oreochromisniloticus), Chinese carps (silver, bighead and grass carp). The prospects of Cambodia's aquaculture industry are called into question by these findings, as it is currently organized, to make a significant contribution to employment, food and nutrition security, and rural economic development. We propose actions to increase sector sustainability and contribute to desired development outcomes

Full textAbstract:
Fish mortality has an enormous impact on the aquaculture industry by reducing fish production and slowing industrial growth. A cross-sectional study was carried out in Kirinyaga County, Central Kenya, to evaluate potential risks of fish mortality and disease transmission and suitability of pond water for rearing fish. A semistructured questionnaire that focused on general information, management practices, and disease history was administered to 92 small-scale fish farmers. Parasitological examination of fish sampled from selected farms (farms that were reporting mortality at the time of sampling) was done by following the standard procedure. Water quality parameters for 33 ponds were evaluated in situ (recorded on pond site) and ex situ (analysed at the laboratory) following the standard methods. The risks were assessed by adjusted odds ratio based on univariate regression analysis. Prevalent fish husbandry practices that were found to be associated with fish mortality and acquisition of pathogens in the study area were the use of raw livestock manure (0R = 1.500), high fish stocking density (0R = 1.168), and feeding fish on homemade rations (0R = 1.128). Parasitological investigation found infestation with Diplostomum spp., Dactylogyrus spp., Clinostomum spp., and Piscicola leeches. Water temperature and pH were found fit for rearing fish. Of the 33 fishpond water samples tested, 1 (3%) and 6 (18%) exceeded the recommended limits of <100 mg/L and <0.2 mg/L of nitrate and nitrite, respectively. Of the 29 fishpond water tested, 15 (59%) exceeded the recommended limits of <100 mg/L of total ammonia. The findings show that the use of raw livestock manure, high fish stocking density, high nitrates and nitrites, and high ammonia levels in fishponds are potential risk factors for fish mortality and acquisition of infectious pathogens in a pond environment in a rural setup, in Central Kenya. There is a need to address the above factors in small-scale farming practices to minimize fish loss and also to prevent the occurrence and spread of infectious pathogens.

Abstract Although the natural conditions of Uzbekistan do not allow to start fishing on a large scale, in order to meet the needs of the population for fish meat and products, attention is being paid to the development of this industry at the level of possibility. In Uzbekistan, fishing is mainly raised in naturally and artificially created ponds of 1-2 hectares, in reservoirs and lakes up to 5 hectares in size. One of the most important tasks in raising fish is to feed them properly and to distribute nutrients equally. However, due to lack of equipment used in fish feeding, this process is done manually. This makes it difficult to feed fish in larger ponds or during rainfall, and it is not possible for them to distribute the food evenly. Considering this we conducted research on the development of a device that distributes food to fish, and an experimental sample of the device was developed. The mass of the device is not more than 100 kg, it can penetrate up to 3 m into ponds and basins, and when necessary, for example, when loading feed into a hopper, it is possible to move back and bring it to the edge of the pond.

The world saw a reduction in the phenomenon of environmental effects during this year's Covid19 pandemic. So far, fishing pond tours have already been classified as quiet tour packages because their activities depend on simply sitting around and waiting for fish to become interwoven on the fishing line. Visitors have been few, although most people are aware of its existence, apart from those who share interests. The fishing pond tour "Cak Rul Fishing" was chosen because it had more visitors than other fishing ponds. However, with many advances in technology and existing technological advancements, pond tourism should be able to take advantage of it so that more people are aware of these things. The goal of this research is to become more aggressive in trying to introduce the fishing industry to society. The methodology used in this research is a descriptive method with an analytical-qualitative methodology. While field studies and literature studies are being used to conduct research. According to the research results of his research, in order to improve tourist visits, appropriate information about the existence of fishing pond tourism is deemed necessary, along with attractive promotional programs to attract almost all old and new prospective customers. Policies must be able to give quality details and be easily accessible to the people, and the public must be equipped with sufficient details and praise fishing pond tourism through media platforms.

In this scenario, a rice and fish farming system is merged, where the fish are farmed alongside or interchangeably with the rice. Integrated fish farming is a sequential linkage between two or more farming operations. However, occasionally the advancement of rice-fish farming has been ham-pered by changes in rice growing methods as well as the widespread use of insecticides and artifi-cial fertilizers. A cutting-edge agricultural technique where the primary crop is rice and fish fin-gerlings are used as a secondary source of income. By generating employment opportunities and ensuring food security, rice cum fish culture not only helps farmers who are living in poverty to earn more money but also increases the output of their paddy crops. This study aims to assess the performance of the fish as a result of the rice-fish culture. Kwadom, in the Yamaltu-Deba local government area of Gombe State, Nigeria, practiced rice-fish culture. The study used six (6) rice paddy fields with the labels "pond X and X1 received artificial feed, pond Y and Y1 received poultry dropping, and pond Z and Z1 serve as control." at twenty-one (21) days following plant-ing, local rice seedlings Jamila and improved rice seedlings Faro 44 were transferred into the paddies. Each pond received 5 g of Clarias gariepinus per fingerling. But only one treatment (X and X1) produced positive results for the rice variety faro 44, which managed to live. When compared to the other 2 treatments (poultry dropping and control), the fish output in treatment one (artificial feed) had an overall weight (g) of 54000 g, which is considerably greater. The study's high mean in faro 44 reading of 96264.73 g was observed. An analysis of resource use efficiency found that, with the exception of labour, irrigation, and insecticide, most resources in the rice-fish industry were underutilized by farmers. In order to improve food security and maintain sustained rural development, it is crucial that the government actively supports the integration of rice and fish farming.

Introducing Biofilter as a Technique for Solving a Problem of Organic Pollutan at Brachiswater Pond at Lakkang Village, MakassarAbstract: Fish/shrimp culture at pond is one of income source for coastal community. Water sources for brackhiswater pond come from river and estuary. The quality of water source for this pond depend on the quality of river and estuary. On the other side, people use river to through it their waste not only domestic waste but also industrial waste along the river, consequently the pollutant in the river is high. Brackishwater pond along Tallo river has a source of water from River and Tallo Estuary. A high organic concentration in the Tallo River has a significantly effect to the production of shrimp/fish pond. A low water quality due to high organic matter could decrease the production of pond and farmers could not be able to grow out fish/shrimp for all year due to in particular month was occurred an increasing significantly of organic pollutant in the river. Introducing biofilter method to farmers for increasing pond water quality and reducing organic waste in the pond is very important, so farmer could apply this simple biofilter technique for solving a problem of a high organic matter in their pond. Applying biofilter techinique could be expected increasing water quality in the pond, consequently it could increase shrimp/pond production of farmers.Keywords: Biofilter, organic pollutant, Shrimp/fish pond, Tallo River and Lakkang Village.Abstrak: Budidaya ikan/udang di tambak merupakan salah satu sumber pendapatan masyarakat pesisir.

Full textAbstract:
The use of purified slaughterhouse wastewater in carp ponds, and the use of wastewater from the pond for the irrigation of agricultural fields, was the basis for the construction of an integrated system of agricultural production as a sustainable solution for the food and fish production industries. The negative side of such integrated production systems is the concern related to the safety of fish meat produced in such a system. The aim of this research was to determine the concentration of heavy metals and metalloids in the wastewater from the slaughterhouse, in the pond water and sediment, in the carp tissue and in the water leaving the pond, and to evaluate the effectiveness of the integrated system and the safety of the produced fish. Sampling was carried out in spring and autumn. The mean concentrations in all water samples (µg/L) were: As (12–125), Cd (0.12–4.2), Hg (1.14–14.21), Pb (<0.1–17.2), Cu (<0.1–44.6), Fe (17.02–425.2) and Zn (2.91–186.2), with the highest numbers in the wastewater, where it was above the prescribed limit values for the wastewater discharged from the slaughterhouses into natural recipients in both samplings. The efficiency of the wastewater treatment plant for heavy metals and metalloids was very high, in the range of 87% to 98%. The water from the pond corresponded to class 3 in terms of the concentration of heavy metals and metalloids both in spring and autumn, and can be used freely for breeding cyprinid fish species. The water from the irrigation canal corresponded to class 2/3 and can be used for irrigation. The mean concentrations of heavy metals and metalloids in the sediments (mg/kg) were: As (3.00–4.88), Cd (0.16–0.96), Hg (0.21–1.47), Pb (0.77–2.29), Cu (49.60–60.90), Fe (3.94–5.32) and Zn (92.8–115.20). The content of heavy metals in different organs of carp differed significantly depending on the season. The trend of heavy metal accumulation in common carp muscles in spring was: Zn > Fe > Cu > Pb > Hg > Cd > As, and in autumn: Zn > Fe > Cu > Pb > As > Cd > Hg. Metal concentrations in the examined fish samples were far below the WHO guidelines. It can be concluded that carp produced in a pond supplied with purified wastewater from the slaughterhouse industry, in terms of the concentration of residues of the tested heavy metals and metalloids, is safe for human consumption.

Background: Aquaculture in Ghana is very profitable, but faces sustainability challenges. This paper assessed the impact pathways by which climate change affects the production and profitability of small-scale aquaculture in Ghana. The study analyzed and compared the economic value of smallholder fish farms with and without the incidence of climatic parameters. Methods: Simple random sampling and purposive sampling techniques were used to select the study area and farms. A total of 30 farmers were interviewed using a questionnaire-based interview. Additionally, using document analysis, observation, and data on farms’ production input and output values, the economic impact of climate change on fish farms was assessed. Results: Extreme temperatures, erratic rainfall, floods, drought, storm and erosion are prevalent in fish farms. Available data shows a decrease of 53.4% of small-scale revenue, a 6.9% reduction in small-scale aquaculture value from GH¢ 1,200,000 to GH¢ 83,000, reducing fish supply by 25%. The findings indicate that the profitability, economic value, and livelihoods of the small-scale aquaculture industry is greatly affected by changes in climate. The incidence of floods, drought, erratic rainfall, erosion, and extreme temperature synergistically induce poverty. The implication on the livelihoods of fish farming households is very alarming and poses a serious threat to food security in the country. Conclusion: Based on the findings, this study concludes that; floods, rainfall temperature, and drought are the major climatic factors affecting the profitability and sustainability of the pond aquaculture industry. The preliminary recommendation is that there is an urgent need to map out flood-free zones close to perennial water bodies to overcome floods and droughts. Planting trees around ponds to create a micro-ecologies ideal for fish culture and also the construction of water storage facilities and proper dyke design would overcome drought and erosion issues. The adaptive capacity of fish-farmers must be built.

Catfish is one of the fishery products favored by the community because of its high protein. So that Catfish is one of the fish that is the center of business for fish farmers. The pond conditions used by Catfish farmers are generally still conventional. So that the maintenance of clean water in ponds is still done manually and even escapes attention. Water conditions will affect the health and productivity of Catfish. In order to achieve the optimum conditions in the third media, a control system consisting of three types of sensors will be used, namely Flowmeter, LDR sensor and LM35 sensor. The flowmeter sensor is used to regulate the flow of water, the LDR sensor functions as a receiver that is used to detect the level of turbidity of water based on how much light enters the water (turbidity). Meanwhile, the LM35 sensor functions to detect the temperature in the media so that the optimum condition for Catfish based on temperature parameters is around 22 - 32 ° C

Full textAbstract:
The study aimed to evaluate the level of environmental pollution from shrimp farming in coastal areas of Soc Trang province. A total of 10 shrimp farming households and 50 neighbouring households were interviewed about emissions and environmental sanitation conditions. At the end of the shrimp season, pond water samples were collected from 5 semi-intensive ponds and 5 intensive ponds, bottom sediment samples were collected from 5 semi-intensive ponds to evaluate the level of pollution. Interview results indicated that wastewater and bottom sediment from shrimp farming are the main causes of declining surface water quality and reducing the number of wild fish; pollution levels are likely to increase in the future. The pH, total suspended solid (TSS), BOD5, and chemical oxygen demand (COD) values of pond water samples are suitable for shrimp farming (except TSS of water samples in Cu Lao Dung and Long Phu); total Kjeldahl nitrogen (TKN) and total phosphorus (TP) contents fluctuate widely between sampling ponds. The metal content in the bottom sediment is lower than the allowable discharge threshold of sediment quality standards. Solid waste generated in farming areas has not been properly collected and treated. To sustainably develop the shrimp industry, local authorities need to encourage shrimp farmers to apply proper waste treatment technologies in addition to state management solutions.

An important place in meeting the needs in food of the population has fisheries. The development of this industry, the increase in production and ensuring the high quality of fish as a food product greatly depend on the animal health of the farms and timely conducting veterinary and preventive measures – the basics of providing the mepizootic well-being. Fisheries in Ukraine engaged in more than 6 thousand individuals and legal entities. However, as evidenced by the practice of recent years and results of ichthyoparasitic studies, almost all fish planting and uterine young in the fish farms of Ukraine is infested by invaders of invasive diseases, including ichthyophthiosis, argulosis, lerneosis, fingerprinting, hydrodactylosis, diplozoonosis and others. Unfortunately, one of the disadvantaged regions of Ukraine with invasive fish diseases is west. In the pond farms of Rivne and Volyn regions it is wide the parasites were distributed: diplastomids and filometers, the larvae of which affect the muscle tissue and internal organs of the fish. In the ponds of Western Polissya of Ukraine has identified 23 species of parasites belonging to the classes of Monogenea, Hirudinea, Bivalvia and Crustacea. It should be noted that in most farms mainly mixed infestations are common in the western region. In the south of Ukraine, diplo- stomosis, metogonimosis, filometridosis, lerneosis and hepaticosis were registered. In the natural reservoirs of Mykolaiv invasiveness of fish of different species by P. ovatus metacercariae was revealed. Fishes of artificial and natural reservoirs of Kharkiv region were found 16 species of parasites belonging to the classes of Trematoidea, Cestoidea, Nematoda,Acanthocephala, Crustacea, Mastigophora, Infusoria and Monogenoidea. In the fish farms of Cherkasy, Zhytomyr and Kyiv areas in most cases the fish was struck by monogeneas. In the natural waters of Sumy region were registered trienophorosis and rafidoscaridosis. It is known that the infection of fish with parasites causes a delay in its growth and development, reduction of fatness, deterioration of product and taste, impaired reproduction and even death. Therefore regular monitoring of parasitofauna of fish in the pond farms of Ukraine is necessary because study of patterns of occurrence and spread of fish diseases, prediction of those diseases affect the efficiency of aquaculture breeding and preservation of fish products.

Based on a generalization of an extensive array of statistical and analytical data, an analysis of the state of the fishery complex of Russia and the Krasnodar Territory was carried out. The industry’s contribution to solving the problem of food security has been determined. A fairly high degree of self-sufficiency of Russians in fish products has been noted. The current state and features of the functioning of the global and Russian fishing industry are determined. Based on the UN FAO Blue Transformation program, a global trend has been identified to increase the production of commercial aquaculture and the prerequisites for its development in Russia. At the same time, it is indicated that the degree of development of aquaculture in Russia does not correspond to the natural capabilities of the country. Based on an analysis of the state of aquaculture in the south of Russia, the reasons for the decline in the level of commercial fish production in freshwater bodies of the southern regions of the country are identified. The prospects for the restoration and development of commercial fish farming in pond farms and lake-type farms have been determined. The reserves for expanding the areas of aquaculture, including mariculture in the coastal part of the Black Sea coast of the Krasnodar Territory are outlined. The feasibility of developing commercial aquaculture in RAS installations in small forms of management and the need to modernize the industry are substantiated. Proposals have been formulated on the need to further expand government support measures and search for options for more accelerated development of fish feed production in order to reduce import dependence. It has been proven that in modern conditions aquaculture is the driver of the fishery complex. For further successful development of the industry, a favorable investment climate, financial support from the state, and the development of public-private partnerships in the implementation of relevant projects are necessary. The progressive development of the aquaculture industry will expand the range of fish products, increase their consumption by the country’s population, and increase employment and income levels.

Full textAbstract:
ABSTRACT Musty “off-flavor” in pond-cultured channel catfish (Ictalurus punctatus) costs the catfish production industry in the United States at least $30 million annually. The cyanobacterium Oscillatoria perornata (Skuja) is credited with being the major cause of musty off-flavor in farm-raised catfish in Mississippi. The herbicides diuron and copper sulfate, currently used by catfish producers as algicides to help mitigate musty off-flavor problems, have several drawbacks, including broad-spectrum toxicity towards the entire phytoplankton community that can lead to water quality deterioration and subsequent fish death. By use of microtiter plate bioassays, a novel group of compounds derived from the natural compound 9,10-anthraquinone have been found to be much more selectively toxic towards O. perornata than diuron and copper sulfate. In efficacy studies using limnocorrals placed in catfish production ponds, application rates of 0.3 μM (125 μg/liter) of the most promising anthraquinone derivative, 2-[methylamino-N-(1′-methylethyl)]-9,10-anthraquinone monophosphate (anthraquinone-59), dramatically reduced the abundance of O. perornata and levels of 2-methylisoborneol, the musty compound produced by O. perornata. The abundance of green algae and diatoms increased dramatically 2 days after application of a 0.3 μM concentration of anthraquinone-59 to pond water within the limnocorrals. The half-life of anthraquinone-59 in pond water was determined to be 19 h, making it much less persistent than diuron. Anthraquinone-59 appears to be promising for use as a selective algicide in catfish aquaculture.

Kolaka Regency is one of the regencies in Southeast Sulawesi Province. The pond area in Kolaka marks it as one of the peculiarities of the region, moreover the majority of the heads of their families have jobs as pond farmers. Inland fishery business remains the main business field, because it is a sector that produces local community consumption as well as fishery product distribution channel business for processing industry companies. In Sabilambo Village, most of the women only work as housewives. In general, a housewife has enough free time to do activities that can increase her income. So far, the catch of this fish is only processed as ordinary kitchen preparations by the women of Sabilambo Village with stir-fried spices and yellow gravy. Meanwhile, the fish will have added value if it is used to be processed into diversified food products. Community empowerment service in Sabilambo Village aims to provide housewives with references to make additional income through training in making catfish meatballs. Improving the insight and capability of human resources is the main thing in economic development in a region.

Full textAbstract:
The fast growing and highly tolerant fish Nile tilapia is one of the most commonly raised fish in the aquaculture industry. To produce an all-male population, a common practice is to feed the Nile tilapia fry with 17α-methyltestosterone (MT)-impregnated food. Uneaten fish food with MT may accumulate in the masculinization ponds and be released into the receiving waters. Not much is known about the fate of MT in the fish farms and in the receiving streams. The objective of this study is to investigate the biodegradation of MT under aerobic condition and to isolate responsible microorganisms. Aerobic biodegradation tests were conducted with MT concentrations of 0.3, 1.0, 5.0, 7.0, and 10.0 mg/L using sediment from the masculinization pond as microbial seed. The results suggested that MT is biodegradable. Lag phase was not observed in all cases. With initial concentrations of 0.3, 1.0, 5.0, 7.0, and 10.0 mg/l, the first-order degradation rates were 0.52, 0.23, 0.17, 0.13 and 0.10 day−1, respectively. Degradation rates were found to decrease with an increase in the initial MT concentration. Analysis of 16S rRNA gene sequences of a strain isolated from the sediment indicated that the strain was highly similar to Pimelobacter simplex strain S151 (100%) which is in the genus Nocardioidaceae. Using this strain, MT is degraded with a first-order degradation rate of 0.044 h−1 excluding the lag phase. This is the first work reporting biodegradation of MT and isolation of MT-degrading bacterium from environment.

Full textAbstract:
This article presents a study of the technology of growing carp (Cyprinus carpio) using different stocking densities in feeding ponds. Carp is one of the most common and essential freshwater fish species for commercial farming and consumption. The study was conducted over several months, with an assessment of carp's growth, survival, and productivity when using different stocking densities in feeding ponds. Different stocking densities included low (sparse), medium, and high (dense) carp individuals per unit area. To experiment, four groups of carp individuals were kept in feeding ponds at different stocking densities from 2,000 to 3,500 specimens per hectare of water area. Using extensive planting material of carp with an average weight of 55 g makes it possible to obtain commercial carp with an average weight of 485 g to 650 g during a two-year cycle of cultivation in the conditions of the second fish farming zone without reducing fish production. At the same time, the largest concentration of carp was obtained in a pond with sparse planting of annuals – 2.0 thousand specimens/ha. An increase in the planting density of yearlings of carp to 3.5 thousand units/ha led to a decrease in the average daily weight of two-year-old carp to 510 g while maintaining a high fish production of 1122 kg/ha. At the same time, a hydrochemical analysis was carried out in the ponds, and the amount and biomass of the natural feed base (phyto-, zooplankton, and zoobenthos) were determined. The analysis of the research results indicates that the stocking density of carp has a significant impact on its productivity. The sparse stocking conditions promoted more significant growth and better development of the fish, which may be due to less competition for food and space. On the other hand, high stocking density led to a slight decrease in growth and did not affect survival and fish productivity. The results of this study have practical applications for fish farms engaged in the cultivation of carp. They emphasize the importance of an optimal balance between the number of fish, the availability of natural feed, and the area of the feeding ponds in order to achieve maximum growth and productivity with minimum costs of keeping and feeding the fish. Such research will help improve fish farming technologies and optimize production processes to ensure sustainable and efficient development of the industry.

Bangladesh is now the world fourth largest inland fish producer and more than half of it comes from aquaculture according to 2012 ranking. The shrimp and prawn industry has gained an important place in the national economy and is the third highest foreign income earner. Concomitant with the growth of the shrimp and prawn culture industry has been the recognition of the ever increasing importance of disease, especially those caused by infectious agents. Few studies have aimed to identify the perception of risk and risk management strategies for small scale aquaculture facilities. The aim of this study was to understand existing health management practices in regards to water management practices and salinity in southwest coastal region of Bangladesh. Questionnaires were specifically designed to gather information on shrimp and prawn culture systems and multiple variables relating to disease outbreaks. A total of eight variables related to health management practices throughout production cycle were investigated comprising location of farm from primary source of water, pond preparation technique, water management practices, in-pond nursing of post larvae (PL), source of PL, salinity level, stocking density and bio security practices. The results found that sharing of water source with other farms, non tested PL, high salinity level, shallow pond, lack of in-pond nursing were considered as diseases risk factors for poly-culture farming system. Furthermore, rainy season (June-August) is risk factors for diseases outbreak because sudden change of salinity level and drop temperature due to rain and freshwater upstream flow. However, risk factors are not direct causes of mortality; instead, risk factors contribute to mortality.

A study was carried out to observe the growth performance of Indian major carp utilizing the shrimp industry waste in their supplementary diets in pond system during 1st January to 30th June, 2015. Two types of diet namely Diet-1 (Formulated feed with shrimp waste), Diet-2 (Formulated feed with plants source ingredients) were prepared while Diet-3 (Commercial feed) were purchased from the market and assigned to three treatments viz. T1, T2 and T3. Protein percentage of diets were 28.42%, 28.13% and 27.32%, respectively. The water quality parameters of the experimental ponds were monitored at 10 days interval. Diet-1 resulted better growth with Labeo rohita (153.68g), Gibelion catla (170.14g) and Cirrhinus cirrhosus (84.83g) compared to Diet-2 (138.99g, 152.94g, 68.39g respectively). The highest SGR (%/day) value was obtained with Labeo rohita (2.66%/day), Gibelion catla (2.59%/day) and Cirrhinus cirrhosus (2.62%/day) for Diet-3. The average protein efficiency ratio (PER) for Diet-1 (2.19) differed much to that of Diet-2 (2.03) where Diet-3 (2.38) showed highest PER value. The highest survival rate (%) with Labeorohita (93.93%), Gibelioncatla (92.86%) Cirrhinuscirrhosus (94.44%) were found for Diet-3. Therefore, it could be recommended that shrimp industry waste can be replaced with fish meal in the diets of Indian major carps along with other available feed ingredients.

Full textAbstract:
Asia dominates the world’s aquaculture sector, generating almost 90 percent of its total annual global production. Fish, shrimp, and mollusks are mainly farmed in land-based pond aquaculture systems and serve as a primary protein source for millions of people. The total production and area occupied for pond aquaculture has expanded rapidly in coastal regions in Asia since the early 1990s. The growth of aquaculture was mainly boosted by an increasing demand for fish and seafood from a growing world population. The aquaculture sector generates income and employment, contributes to food security, and has become a billion-dollar industry with high socio-economic value, but has also led to severe environmental degradation. In this regard, geospatial information on aquaculture can support the management of this growing food sector for the sustainable development of coastal ecosystems, resources, and human health. With free and open access to the rapidly growing volume of data from the Copernicus Sentinel missions as well as machine learning algorithms and cloud computing services, we extracted coastal aquaculture at a continental scale. We present a multi-sensor approach that utilizes Earth observation time series data for the mapping of pond aquaculture within the entire Asian coastal zone, defined as the onshore area up to 200 km from the coastline. In this research, we developed an object-based framework to detect and extract aquaculture at a single-pond level based on temporal features derived from high-spatial-resolution SAR and optical satellite data acquired from the Sentinel-1 and Sentinel-2 satellites. In a second step, we performed spatial and statistical data analyses of the Earth-observation-derived aquaculture dataset to investigate spatial distribution and identify production hotspots at various administrative units at regional, national, and sub-national scale.

Full textAbstract:
Aquaculture is the main promising direction for the development of the fisheries industry. Analysis of the general condition of fish breeding enterprises and the potential for expanding production shows that the growth trend of traditional for the southern regions pond fish breeding is weak. A significant problem for the development of aquaculture is the high price of fish products and, accordingly, low demand. A substantial reduction in the cost of fish production is currently unlikely to be achieved, so switching to more valuable fish varieties can stimulate consumption. To ensure the development of the fish products market and increase demand, entrepreneurs in southern Russia are improving technologies for growing such valuable fish varieties as salmonoids, in particular, rainbow trout. Studying the activities of trout farms requires taking into account which area of activity is prioritized. A farm can produce marketable fish or fish planting material, as well as execute both types of production. The work observes the organizational features of trout farms and promising directions of their development. Solving such key issues as the provision of qualified personnel, high-quality feed of domestic, preferably regional production, and provision of logistically affordable and high-quality planting material is the basis for achieving the goals of import substitution for high-quality fish products in Russia.

The fishery complex of the Russian Federation, due to its natural and climatic conditions, has tremendous potential both for saturating the food market with high-quality products and for the socioeconomic development of the region due to the creation of a large number of highly paid working places and conditions for the provision of services for organizing sports fishing. One of the largest fishery complexes in the Russian Federation is Rostov region where biological resources are extracted by fishery enterprises in the Azov and Black Seas, Taganrog Bay, Tsimlyansk, Veselovsky and Proletarsky reservoirs and numerous pond farms, the capabilities of which are not fully used. Oktyabrsky district has enormous resources of pond fishing and fish farming. On the example of this region, one can observe the influence of all the shortcomings that impede the further increase in the level of development of the fishing industry. The elimination of these shortcomings will not only increase this level, but also contribute to the socio-economic development of theregion.

Full textAbstract:
The study aimed to assess the impact of petrochemical effluent on fish blood, examining both short- term and long-term exposure periods to evaluate toxicity stress symptoms in the rapidly evolving petroleum industry. Various biochemical and hematological parameters, along with enzymatic changes, were analyzed by exposing different organs of freshwater fish, C. catla, to the petrochemical effluent. The results indicated a significant decrease in hemoglobin (Hb) content, red blood cells, packed cell volume, and mean corpuscular hemoglobin (MCH) values. Conversely, there was a notable increase in white blood cells (WBC) during the exposure periods compared to the control. Hematological parameters, including Hb, RBC, mean corpuscular volume (MCV), and MCH, exhibited fluctuating results, with a consistent decrease observed in both short- term (24, 48, 72, and 96 hours) and long-term (10, 20, and 30 days) exposure periods, suggesting the occurrence of anemia in the exposed fishes due to petrochemical effluent. In the biochemical analysis, exposed fish showed a significant reduction in protein, carbohydrate, and lipid content across all organs, accompanied by increased enzyme activity observed in all organs of freshwater fish, C. catla. Consequently, this survey is instrumental in predicting potential risks to the population and aquatic system.

This study evaluated the nature of women’s participation in the fish value chain. Recognizing the indispensable contributions of women in agriculture and fisheries, this research was aimed at illuminating the specific ways in which women engage in the fish value chain and what policies support their aquacultural activities. Qualitative approaches including interviews and focus group discussions were employed. Data was gathered from key informants and women actively involved in small-scale fish farming operations in seven districts of Lusaka Province, with a focused exploration of their roles in the fish value chain and any recommendations they had to enable smooth operations. Document review of policies guiding aquaculture was also done using a gender lens. The findings underscored the multifaceted involvement of women across various stages of the fish value chain, encompassing pond management, harvesting, processing and marketing. Despite their substantial contributions, existing policies lack explicit and targeted measures to address the unique challenges faced by women and to address gender disparities within the aquaculture industry. This research has highlighted the multifaceted role and form of women’s participation in the fish value chain within the context of small-scale fish farming in Lusaka Province, Zambia. The findings underscore the significant contribution of women to various aspects of the fish value chain, including trading and processing, showcasing their adaptability through a blend of traditional and modern methods.

Full textAbstract:
In early 2018, Nick Tommarello could be proud of what he and his partners had accomplished. Their company, Wefunder, Inc., was the acknowledged leader in the equity crowdfunding industry, an industry that he and his partners were largely responsible for creating. Wefunder served as an online portal for crowdfunding investments and had raised more money for more companies than any of their competitors. Yet, Nick’s pride and satisfaction with these accomplishments were tempered by the knowledge that neither his company, nor the industry as a whole, had achieved the volume and size he had originally projected. Wefunder's careful vetting of the companies allowed to raise money on its site had created a reputation for quality, but the labor-intensiveness of this model was limiting the company's ability to scale up for growth. And the restrictive conditions imposed by federal law and the Securities and Exchange Commission’s regulations on equity crowdfunding seemed to prohibit models of doing business deemed essential for the growth of the industry as a whole. If these challenges could not be met, Wefunder might well end up as one of many fish competing in an unfortunately small pond.

Full textAbstract:
In this study, the suitability of four earthen, seawater ponds located in the Thatta district of Sindh province (Pakistan) was evaluated for the purpose of semi-intensive mariculture, which remains to be a severely underdeveloped branch of the agricultural industry of this populous Asian country. Initial pond soil probes were promising, as they showed a high clay and silt content. Monthly water samples were obtained in the year 2019 (from January to December), which allowed for the monitoring of water parameters, as well as the identification and relative quantification of planktic populations. As a result, the monthly variations of basic water parameters were found within optimal ranges for planktic growth (water temperature, salinity, pH, transparency, and dissolved oxygen). Bacillariophyta was the largest phytoplanktic group, with the most dominant species being Sundstroemia setigera, followed by the cyanobacteria Oscillatoria limosa. Copepoda was the most numerous group of identified zooplankton, followed by tintinnids and foraminiferans. Total suspended solids (TSS) calculations indicated up to nine-fold month-to-month reductions of planktic biomass, observed in the form of diminishing Bacillariophyta (December) and Copepoda (June and December). In conclusion, the studied ponds appear to be suitable for semi-intensive mariculture activity due to the abundance of diverse planktic forms (mainly Copepoda—preferable natural food for commercially important fish species), which was achieved even without the use of fertilizers. However, significant drops of planktic biomass may still occur, which implies the need for regular water monitoring procedures, which would in turn allow fish producers to implement periodical adjustments to the administered feeding rates with artificial diets.

Nowadays, fish production aims to achieve a continuous and immediate generation of top-quality animal protein from the finest sources. Moreover, the aquaculture industry holds a vital position in addressing the rising global appetite for fish and seafood products. Additionally, it has played a substantial role in providing affordable animal protein in Egypt in recent years. Therefore, a rapid development has occurred in the industrial aquaculture sector in Egypt to compensate the decrease in the red meat production. According to previous studies, Egypt occupied the 1st rank among African countries and the 9th position globally in the field of fish farming production. This achievement aimed to link up the disparity between fish production and consumption in Egypt. Carp, due to its economic importance in this industry, has expanded worldwide with more evident ecological influences. The Carp fish belongs to the Cyprinidae family, which encompasses seven subfamilies, approximately 220 genera, and has been associated with around 20,000 documented species. Given the importance of carp with different species, this work reviews the management, behavior and different rearing systems of some popular carp species in Egypt. Data search was done on PubMed, SCOPUS, Web of Science, Google Scholar for the keywords including fish farming, carp fish, management, behavior, rearing systems, Egypt, Africa, and Worldwide. In Egypt, the output of carp is ranked second only to tilapia in aquaculture. A polyculture system is more often used in carp rearing, particularly when raising tilapia, in order to maximize growth rates, minimize feed conversion ratios, and reduce the amount of fat in the corpses. Furthermore, agro-ecologically valuable agriculture has been linked to integrated carp monoculture. Crop rising was the key to the successful development of pond aquaculture.

Full textAbstract:
With the development of high-density and intensive aquaculture production and the increasing frequency of water quality changes in aquaculture water bodies, the number of pollution sources in aquaculture ponds is also increasing. As the water quality of aquaculture ponds is a crucial factor affecting the production and quality of pond aquaculture products, water quality assessment and management are more important than in the past. Water quality analysis is a crucial way to evaluate the water quality of fish farming water bodies. Traditional water quality analysis is usually obtained by practitioners through experience and visual observation. There is an observability deviation caused by subjectivity. Deep transfer learning-based water quality monitoring system is easier to deploy and can avoid unnecessary duplication of efforts to save costs for aquaculture industry. This paper uses the transfer learning model of artificial intelligence to analyze the water color image automatically. 5203 water quality images are collected to create a water quality image dataset, which contains five classes based on water color. Based on the dataset, a deep transfer learning-based classification model is proposed to identify water quality images. The experimental results show that the deep learning model based on transfer learning achieves 99% accuracy and has excellent performance.

Full textAbstract:
TDR Catfish Farmer Sultan Adam Banjarmasin is a home industry (IRT) engaged in the business of catfish farming located on Jl. Sultan Adam No.17 RT.22, Surgi Mufti, North Banjarmasin. In the management of catfish farming, water quality is an important factor in the success of cultivation where poor water quality can cause fish to be more susceptible to disease. Apart from these needs, the TDR of Sultan Adam Catfish Farmers actually has problems in the process of monitoring pond water quality conditions which are currently carried out manually and periodically by breeders. This process is considered ineffective because it is difficult to determine water quality from the physical condition of the water which changes rapidly due to weather or fish feed residue. The solution offered to solve this problem is to develop a tool that can monitor temperature conditions and the acidity of catfish pond water automatically and in real time. This innovation was developed by utilizing the Internet of Things (IoT) through the use of the DS18B20 temperature sensor and SS15 pH sensor on the ESP32 WROOM-32D microcontroller. The results of system testing from fuzzy logic calculations at the output of the microcontroller and Matlab and the suitability of expert information in determining pool water quality obtained an average error value of 0.46%. Based on these results, it can be concluded that the IoT-based water quality monitoring system in determining water quality is suitable for direct use.

There are 115 million operational holdings in the country and about 80 % are marginal and small farmers. To fulfill the basic needs of house hold including food (cereal, pulses, oilseeds, milk, fruit, honey, meat, etc.), feed, fodder, fiber, etc. warrant an attention about Integrated Farming System (IFS). Undoubtedly, majority of the farm- ers are doing farming since long back but their main focus was individual components but not in a integrated manner. At the ICAR and State Agricultural Universities level, lot of efforts have been made aiming at increasing the productivity of different components of farming system like crop, dairy, livestock, poultry, piggery, goat keep- ing, duckery, apiculture, sericulture, horticulture, mushroom cultivation etc. individually but lacking in their inte- gration by following farming system approach. The integration is made in such a way that product of one com- ponent should be the input for other enterprises with high degree of complimentary effects on each other. The fodder fed to the cattle produces milk. The dung, urine and litter produce farmyard manure and energy used for crops and fish pond. The siltation of fish pond is utilized as manure to crops. The farmyard manure can substi- tute about 25% of recommended N P and K for crops, besides improving the physical and biological properties of soil. The fish pond water can be used by gravity method while there is breakdown in electricity supply. Oil- seeds provide nectar for honeybee, edible oils for human and oilseed-cake for animal feed. Integrated nutrient management can enhance the productivity of cereals by 0.5 to 1.0 t/ha. Processing of different products en- hances the value addition to the extent of 25 to 50% besides generating 50-75-man days/ family/ year of em- ployment. The fish pond embankment comprising 20-30% can be used for growing cucurbits and fruit trees which provide effective soil cover to checks the soil erosion and also make the system economically viable. The apportionment of farm land involving different enterprises, viz., cereal (40%), pulses (10%), oilseed (10%), horti- culture (15%), fishery (10%), livestock (10%), poultry/piggery/goatry (2%), storage, threshing floor, implement shed, vermicompost, straw storage and farm building etc. (3%) for the efficient use of resources available and to enhance the input use efficiency. The preliminary research investigations advocated the benefits of productiv- ity improvement by 30-50% depending upon the number and kind of enterprises and their management. The in- formation on farming system in a systematic way is presented here. The methodology is explained keeping in mind the work done so far to realize better productivity, profitability and sustainable production systems that would help to solve the fuel, feed and energy crisis, create more employment avenues, ensure regular income and encourage agricultural oriented industry.

Mekarmulya Village is one of the 10 villages included in the administrative area of Telukjambe Barat District, Karawang Regency. Headed by a village officer and assisted by a village secretary and all village officials. Mekarmulya Village is known as the center of the cottage industry for making pressed red bricks. Almost all residents become red brick makers. However, gradually this business became sluggish and could not compete with the light bricks. The sluggish sales of red bricks were also felt directly by the workers who worked in one of the red brick craftsmen. On the other side, there is the potential for the ex-excavated red brick material to become a pond for freshwater fish resources as an additional stage for the red brick craftsmen, which is starting to decline. For a while, the fish that refused to start was tilapia because it was easy to adapt to the environment and quickly reproduced. Apart from cultivating fish and selling it raw, it is also advisable to sell fish products in the form of processed food such as nuggets, smoked fish, and others.

The innovative study "Fuzzy Logic Empowered NetWatch: Revolutionizing Aquaculture with IoT-based Intelligent Monitoring and Management in Bangladesh" is a step towards the dawn of a new era in fish farming techniques that emphasize accuracy and efficiency. Using fuzzy logic controllers in the NetWatch system, stakeholders involved in aquaculture can access a degree of intelligence and adaptability that is not possible with standard management techniques. Fuzzy logic techniques are included in NetWatch, allowing it to make intelligent judgments based on the intricate and frequently unpredictable nature of aquaculture systems, in addition to monitoring and controlling environmental parameters and water quality. Because of its dynamic adaptability, the system can mitigate risks and optimize results in real time while successfully responding to changing situations. Furthermore, NetWatch offers a comprehensive picture of the aquaculture ecosystem by combining pond-specific data with more general environmental insights, facilitating better-informed macro and micro decision-making. With this thorough knowledge, fish farmers can allocate resources more efficiently, reduce waste, and sustainably increase productivity. Moreover, Fuzzy Logic Empowered NetWatch's revolutionary potential offers opportunities for the aquaculture industry, transcending the boundaries of individual fish ponds. Bangladesh can establish itself as a global leader in sustainable aquaculture methods and set new benchmarks for production, efficiency, and environmental stewardship using IoT-based intelligent monitoring and management. Fuzzy Logic Empowered NetWatch catalyzes a systemic shift in how we approach aquaculture management rather than merely technology. Bangladesh may achieve previously unattainable levels of sustainability and productivity by utilizing fuzzy logic and the Internet of Things. This would guarantee a better future for the country's aquaculture sector and the communities it serves.

Muarareja Village is one of the potential centers of marine fish processing activities in Tegal City with three main sectors, namely the fish processing industry, pond farmers, and fishermen. Most of the fish processing industry in Tegal is still categorized as Small Micro Medium Enterprises (MSMEs), including the Mina Rizqi fish processing group. This group still uses simple equipment in processing, does not pay attention to SOPs in supporting CPPOB (Good Processed Food Handling Methods) and lack of awareness of the importance of product quality certification from bacterial contamination indicated by COA. In this service activity, an innovative and effective approach was taken to improve the quality of marine fish processing products with pulsed electric field (PEF) technology which has successfully reduced marine fish bacteria. With our industrial equipment and institutional support on Teaching Factory, we worked together with the Tegal city Marine and Fisheries Extension Service and the Mina Rizqi fish processing group to improve the quality of fish products with PEF technology. The method used in this program is by providing training on PEF technology and providing assistance on how to use PEF by students. Assistance in managing COA(Certified of Analysis) and Good Processed Food Production Methods (CPPOB). The result of this program is the application of PEF technology in the fish processing of the Mina Rizqi fish processing and marketing group. Thus, the quality of processed fish can be maintained and the shelf life can be extended. As well as having COA and CPPOB documents to support wider marketing, namely retail markets and exporters.

Full textAbstract:
Catfish production is a major aquaculture industry in the United States and is the largest sector of food fish production. As producers aim to optimize production yields, diseases caused by bacterial pathogens are responsible for high pond mortality rates and economic losses. The major bacterial pathogens responsible are Edwardsiella ictaluri, Aeromonas spp., and Flavobacterium columnare. Given the outdoor pond culture environments and ubiquitous nature of these aquatic pathogens, there have been many reports of co-infective bacterial infections within this aquaculture sector. Co-infections may be responsible for altering disease infection mechanics, increasing mortality rates, and creating difficulties for disease management plans. Furthermore, proper diagnoses of primary and secondary pathogens are essential in ensuring the correct treatment approaches for antimicrobials and chemical applications. A thorough understanding of the interactions and infectivity dynamics for these warm water bacterial pathogens will allow for the adoption of new prevention and control methods, particularly in vaccine development. This review aims to provide an overview of co-infective pathogens in catfish culture and present diagnostic case data from Mississippi and Alabama to define prevalence for these multiple-species infections better.

The material for this report was the results of bacteriological examination of fish of various species (silver carp (Carassius gibelio); silver carp (Hypophthalmichthys nobilis); white cupid (Ctenopharyngodon idella); common carp (Cyprinus carpio); rainbow trout (Oncorhynchus mykiss), fry of sturgeon of Lena (Acipenser baeri) and sterlet (Acipenser ruthenus)) and various age groups in 2016–2018. in 7 fish farms in Belarus. As a result of research, 21 species of bacteria have been registered in introduced fish species in pond farms that are potential causative agents of bacterial diseases of introduced fish. Two types of bacteria – Shewanella putrefaciens and Aeromonas hydrophila – are invasive and harm the fish industry. Studies have shown seasonal changes in the frequency of occurrence of Sh. putrefaciens and A. hydrophila in introduced fish. During January-March, the infection of fish with A. hydrophila bacteria was not high, increasing sharply in April-May. In June-July, a decrease is observed, and in August is a sharp decrease in the infection of the internal organs and blood of fish with aeromonads. Bacteria Sh. putrefaciens were found in fish much less frequently than A. hydrophila, however, some seasonal dependence in the change in the frequency of its occurrence in introduced species is observed. The peak of occurrence is in June. The maximum values of the frequency of occurrence of pathogens of bacterial infections were noted for A. hydrophila in April (80.0%), for Sh. putrefaciens – in June (33.0%). It should be noted that the active consumption of mixed fodder and natural feed by the fish leads to the restoration of the body’s immune status after winter.
