Abstract:

Abstract The process of fish migration is one of the most important biological aspects of the life of certain fish species, including fish species that live in freshwaters. In Indonesia’s freshwaters, several types of fish migrate to fulfill parts of their life cycle, such as Anguilla spp., Tor spp., and Rasbora spp., which have economic and ecological values. Fish habitats and migration routes can be affected by many cause changes, including dam constructions, other infrastructure constructions, drainage of wetlands, and floodplain disconnection. Other threats to migratory freshwater fish are overfishing and pollution. In Indonesia, most migratory freshwater fish threats were obstructions to free-flowing rivers, such as dams, and the exploitation of adult fish that migrate for spawning. Some management approaches should conserve and sustain the use of migratory freshwater fish.

Abstract:

The study was done to review some saltwater and freshwater fish species in the Niger Delta region of Nigeria. The Niger Delta is one of the most prominent regions in Nigeria, endowed with several water bodies that are distributed as freshwater like rivers, lakes, streams and creeks. These freshwater ecosystems in the region, are abundantly endowed with fish species such as Clarias gariepinus, Pila ovate, Labeo coubie, Synodontis budgetti and Synodontis eupterus. Apart from the freshwaters, the region also has vast marine ecosystem with abundance of fish species such as Elops lacerta, Mugil cephalus, Thais coronata, Periophthalmus papilio, Tympanotonus fuscatus, and Sardinella maderensis. Unfortunately, many of these fish species are endangered due to constant pollution in the Niger delta regional coastal environment. As a result, it is important to document some available freshwater and marine water fish species which will serve as a reference material for both academics and research institutions, should any of the fish species go into extinction.

Abstract:

Freshwaters are important, interconnected, and imperiled. Aquatic ecosystems, including freshwater fishes, are closely tied to the terrestrial ecosystems they are embedded within, yet available spatially explicit datasets have been underutilized to determine associations between freshwater fishes and forested areas. Here, we determined the spatial co-occurrence between freshwater fish distributions and forests within 2129 watersheds of the conterminous United States. We identified 21% of freshwater fishes as associated with forested areas, and 2% as strictly present only in highly forested areas (75–100% forested). The northern coasts and southeast regions, both heavily forested, showed the largest numbers of forest-associated fishes in highly forested areas and fish species richness. Fish associated with low-forested areas occurred in the southwest and central plains. Imperiled fishes were relatively evenly distributed among percent forest categories, which was distinctly different from patterns for all fishes. The identification of forest-associated fishes provides insights regarding species-specific landscape contexts. Determining these large-scale patterns of freshwater biodiversity is necessary for conservation planning at regional levels, especially in highly impacted freshwater ecosystems.

Abstract:

The high market demand for freshwater fish needs, because it has become a daily commodity for Indonesian people from upper economic circles or low incomes, the need for freshwater fish is very high. The delicious taste of meat and the vitamins contained in freshwater fish are very good for the human body, therefore aquatic fish cultivators are developing to meet market needs. Various efforts were made to meet the market demand for freshwater fish, starting from increasing the number of ponds, improving fish feed to meet protein needs and paying attention to the pH of freshwater ponds. The use of digitalization of freshwater pH measurements is applied to facilitate control of the tolerance level of freshwater fish.

Abstract:

Freshwater fish seed sellers play several roles in the supply chain process in the freshwater fish farming business. The role of the seller of freshwater fish seeds in this process is to distribute fish seeds which are one of the upstream sources in the supply chain process. Freshwater fish cultivators must select competent freshwater fish seed sellers so the supply chain process can run well. A large number of freshwater fish seed sellers in the market remind freshwater fish cultivators to choose the quality of the freshwater fish seed seller in terms of seed quality, low prices, shipping that can reach many areas, ergonomic packaging, and others. This study proposes Hybrid Naïve Bayes Classifiers (HNBCs) as a machine learning method for classification. This study aimed to compare the seed seller classification method in which the appropriate pattern of seed seller was identified by hybridization of Naïve Bayes Classifiers (NBCs), and then the researchers conducted performance appraisal and evaluation. The results are beneficial for freshwater fish cultivators and researchers which will enable them to formulate their plans according to the predicted results. The proposed method has produced significant results by achieving a training data accuracy of 82.61% and the testing data accuracy of 73.91%.

Abstract:

Water chemistry is thought to be the primary factor influencing fish otolith chemistry. Experimental results with freshwater and diadromous fish have been consistent with this paradigm, but with marine fish, they have often been ambiguous or contradictory. A review of water chemistry data indicated that Sr:Ca (mmol:mol) levels were higher in marine water than in most freshwater systems and that Sr:Ca variability was lower in marine water than in most freshwater systems. We therefore hypothesized that lifetime otolith Sr:Ca profiles of freshwater fish would exhibit low levels of Sr:Ca with moderate variability, of diadromous fish would exhibit highly variable Sr:Ca levels, and of marine fish would exhibit high levels of Sr:Ca with low variability. Otolith Sr:Ca profiles from 81 species of freshwater, diadromous, and marine fish revealed that freshwater fish had low levels of Sr:Ca and lower variability than expected relative to marine fish, diadromous fish had Sr:Ca levels and variability that were consistent with expectations, and marine fish had high maximum Sr:Ca levels, as expected, and high Sr:Ca variability, similar in magnitude to diadromous fish, which was not expected. These findings indicate that water Sr:Ca is the primary factor influencing otolith Sr:Ca variation for freshwater and diadromous fish but not for marine fish.

Abstract:

This study aims to determine the characteristics of freshwater ornamental fish consumers, determine the decision-making process of freshwater ornamental fish consumers, and determine the correlation between consumer behavior and purchasing decisions of freshwater ornamental fish in Bogor. The research held from October to November 2021 at three ornamental fish stores in Bogor (Terang Aquarium, Laladon Ornamental Fish Exchange, Bogor Ornamental Fish Marketing Depot). 50 respondents chosen by accidental sampling technique. The results showed that the consumer characteristics of freshwater ornamental fish varied which were known from the factors of gender, age, education, profession, family of responsibility, monthly income, monthly expenses for freshwater ornamental fish and when they start to buy/keep freshwater ornamental fish. Consumer’s considerations in buying/maintaining freshwater ornamental fish are in terms of how to care, price, ornamental fish’s behavior, size, color, shape, type of ornamental fish and where to buy. The results of the Spearman Rank Correlation analysis show that the cultural variable (X1) has a weak but significant correlation with the purchase decision (Y). The social variable (X2) has a very weak and insignificant correlation. The personal variable (X3) has a weak but significant correlation and the psychological variable (X4) has a strong and significant correlation with a correlation coefficient value is 0.642 and significant value less than 0.05 (0.000 < 0.05). Keywords: freshwater ornamental fish, consumer behavior, purchasing decisions, correlations

Abstract:

Records of cleaning symbiosis between freshwater fish are scarce. Here we report on juvenile catfish, Platydoras costatus, cleaning the piscivorous characin Hoplias cf. malabaricus in a stream of the rio Araguaia drainage in the Brazilian Amazon. The scarcity of records on cleaning behavior in freshwater systems seems to be in part a consequence of the few observational studies under natural conditions in the Neotropics. Otherwise, the rareness of this behavior in freshwaters is possibly related to the short evolutionary time available to the fish fauna to develop these complex interactions, when compared to the ocean environment.

Abstract:

A total of 78 raw retail fish samples from 30 freshwater and 48 marine fish were examined for the presence of Listeria, Aeromonas, and Vibrio species. The overall incidence of Listeria spp. was 30% in freshwater samples and 10.4% in marine fish samples. Listeria monocytogenes (44.5%) was the most commonly isolated species in freshwater fish, and Listeria murrayi (83.5%) was the most commonly isolated species in marine fish samples. Motile aeromonads were more common in marine fish samples (93.7%) than in freshwater fish samples (10%). Vibrio alginolyticus, Vibrio fluvialis, and Vibrio damsela were isolated only in marine fish samples, representing 40.9, 38.6, and 36.3% of Vibrio isolates, respectively. In freshwater and marine fish, the highest incidences of Listeria and Aeromonas were found in skin samples; the highest incidence of Vibrio in marine fish was found in gill samples. The location of Listeria spp. and L. monocytogenes in a fish was significantly different among freshwater fish. A high incidence of these bacterial pathogens was found in the brown trout (Salmo trutta) and horse mackerel (Trachurus trachurus). Handling of contaminated fish, cross-contamination, or eating raw fish might pose a health hazard, especially in immunosuppressed individuals, elderly people, and children. This study highlights the importance of bacterial pathogens in fish intended for human consumption, but more study is needed.

Abstract:

Large freshwater mussels (Unionida) are long-lived, have large bodies, and produce thousands to millions of larvae (glochidia) that usually must attach to host fish tissue to complete their life cycle. This is an obligate parasitic stage of mussel larvae. However, less than one in onemillion find a suitable host and survive. The degree of host specificity varies among unionid species, from specialists that can successfully parasitize only one or a few closely related fish species to generalists that can complete development on a taxonomically broad range of fish species. In addition, freshwater mussels are among the most threatened groups of animals. This is due to habitat destruction, the introduction of non-native species, and the loss of host fish on which their larvae (glochidia) are obligate parasites. Glochidiosis harms fish by affecting their growth; on the other hand, freshwater mussels play an important role in freshwaters by improving water quality and ridding the water of bacteria, algae, and pollutants, they are an indicator species of water quality. During our parasitological survey of fish from the Macedonian part of Lake Prespa in April 2022, many glochidia were found on the gills, skin, and fins of two endemic fishes, Prespa roach (Rutilus prespensis) and Prespa nase (Chondrostoma prespense), in the range of tens to thousands on one host. We thus recorded these two endemic species as new hosts of A. cygnea.

Abstract:

Geologically southern part of New Guinea Island is the oldest part of the mainland and have most speciose of freshwater fish. Asmat is one area in Southern New Guinea where has some large river systems such as Siret and Vriendschap Rivers. There is not much information on freshwater fish diversity of the area. This study aim to know freshwater fish species of both river systems, in order to manage the area as conservation area by local government. Active fish collection method was applied to sample fish of Siret and Vriendschap River Systems. One seine net, 3.6 m length, 1.23 m in height, and with a mesh size of less than 0.5 cm, and traditional scoop net were used to collect fish. The Siret and Vriendschap freshwater fish fauna consist of 22 species in 18 genera and 15 families. Cochlefelis danielsi (Ariidae), Mogurnda cingulata (Eleotridae), Zenarchopterus novaeguineae (Hemiram-phidae), Melanotaenia ogilbyi (Melanotaenidae), Synaptura villosa (Soleidae) are endemic to Southern New Guinea. Spesifically, Mogurnda cingulata (Banded Gudgeon) and Melanotaenia ogilbyi (Ogilbyi’s Rainbowfish) have restricted distribution in Southern New Guinea. Further research in smaller stream and its tributaries might increase freshwater fish diversity of Asmat.Key words: Southern New Guinea, Asmat, freshwater fish

Abstract:

Total fat and fatty acid composition of seven fresh-water and nine marine fish commercially important in Brazil were determined. Palmitic acid was the predominant saturated fatty acid in both freshwater and marine fish. In the fat from freshwater fish the total C-16 fatty acids were higher than in marine fish. Oleic acid was the most abundant monounsaturated fatty acid and it was found in higher levels in freshwater fish. The data revealed that most freshwater fish from Brazil examined were a poor source of eicosapentaenoic (20:5) and docosahexaenoic (22:6) acids. Of the marine fish analysed, only sardine and manjuba could be recommended as a good sources of n-3 fatty acids.

Abstract:

Community Service is carried out in Gunung Menyan Village, Pamijahan District, Bogor, where many residents have livelihoods as freshwater fish farmers. As is known that freshwater consumption fish itself is a fish that can be cultivated and can be promoted as a side dish of daily food, one of the freshwater fish is Tilapia. Tilapia is one type of freshwater fish that is often found by layers of Indonesian society, where Tilapia is often used as a side dish by frying. Currently, the per capita income of Pamijahan residents still relies heavily on the sale of fish Traditional freshwater consumption is by directly selling fresh fish when they harvest the fresh fish or selling directly without processing. For this reason, Community Service this time seeks to help increase the income of residents there by providing solutions by processing the results of fish farming properly and can help improve the economy of the people of Cikoneng Village, Gunung Menyan Village. That is by making Tilapia into processed products in the form of FROZEN Fish

Abstract:

Fish as aquatic animals have several physiological mechanisms that land animals do not have. Differences in habitat cause fish to adapt to environmental conditions, for example as animals that live in water, both in fresh and marine waters. The number of species or types of freshwater fish means knowledge of the types of freshwater fish. Identification of freshwater fish images is useful for the community, because the types of freshwater fish have different nutritional content, prices and processing for each type. Likewise for cultivators, identification of freshwater fish species can be useful for providing fish handling and management because each fish has a different cultivation method. The purpose of this study was to identify freshwater fish species using the Linear Discriminant Analysis (LDA) algorithm based on color feature extraction using HSV. The LDA algorithm has the ability to reduce dimensions by dividing data into several groups by maximizing the distance between groups that are different or more. To make the identification process easier, color feature extraction with HSV can be used to extract a variety of information from the color in the image. Based on the results of the accuracy test, it produces a value of 84.5%, which is included in the good category.

Abstract:

Probiotic products are viewed as an alternative to the use of antibiotics in freshwater fishes farming. Probiotic organisms include bacteria, yeast, and filamentous fungi offering different benefits to fish including growth promotion, inhibition of pathogen colonisation, and improvement of nutrient digestion, water quality, and stress tolerance, as well as enhancement of reproduction. For these reasons, this review aims to identify the main trends in probiotic amendment in freshwater fishes. Strategies to incorporate the probiotic strains in the fish feed or pellets to allow optimal viability of the strains as they reach the fish gastrointestinal tract (GIT) are crucial in probiotic research and commercial applications for freshwater fish.

Abstract:

The ecological aspect of the behavioral and physiological adaptation of fish in the autumn-winter period in water bodies of the temperate and subarctic climatic zones of the Northern Hemisphere is considered. It has been established that fish in the studied areas with a decrease in water temperature form aggregations in deep, low-speed sites for the successful wintering. In the considered period of the life cycle, the metabolism in fish slows down to reduce the depletion of lipid reserves; therefore, this group of aquatic organisms forms accumulations in areas with fundamental properties - depth and low flow rate. This phenomenon can be considered a behavioral-physiological adaptation developed as a result of evolutionary processes. The results of work on the discovery of such wintering grounds have been noted for the continents - Eurasia and North America. Fish families that use such winter refuge include Cyprinidae, Percidae, Coregonidae, Thymallidae, Salmonidae, Lotidae, Esocidae, Siluridae, and Acipenseridae.

Abstract:

Since the Covid-19 pandemic, public interest in raising freshwater fish has shown an increasing trend, considering that now many layers of people work at home so that raising freshwater fish has become an entertainment in itself. The purpose of this research is to change the mindset of the people in Pulo Damar Village, where technological, social, and cultural developments have led to many companies being established to achieve certain goals in meeting human needs. Electronic Business or E-Business is a transaction, buying and selling, business activity carried out through electronic devices or with the internet so that companies can directly interact with customers, suppliers and business partners. Freshwater fish are fish that are easy to maintain, freshwater fish cultivation does not need a large place and large capital, it can be done as a home business. Therefore, we can make this freshwater fish business an online business (e-business) so that this fish business is more increased and can reach a broad market.

Abstract:

Hainan Island is located within the Indo-Burma global biodiversity hotspot, however, the freshwater fish fauna on this island is poorly understood. Based on field investigations and literature review, we compiled a list of 154 freshwater fish species (138 native and 16 non-native) belonging to 10 orders, 31 families and 104 genera found on Hainan Island. Of these, 31 species are endemic to China. The native freshwater fish fauna in Hainan Island is affiliated to South China sub-region of the Oriental Region. Current knowledge suggests that overexploitation, water pollution, flow modification, habitat degradation, and non-native species have severely reduced the freshwater fish biodiversity in Hainan Island. To protect freshwater fish biodiversity and fisheries in Hainan Island, some new measures should be adopted and current measures better enforced. This study constitutes an important resource for conservation management of freshwater fishes in Hainan Island.

Abstract:

This review article presents the updated informationof freshwater Invasive Alien Species (IAS) of fishes of the continents to understand the homogenate progression in global freshwater ecosystems and the leading pathways of freshwater IAS fish introduction throughout the continents. North America contains 45 freshwater invasive fish species within 18 families, which is the most profuse off all other continents, whereas, Australia possesses the lowermost amount of freshwater IAS fish, 18 species under 8 families. Besides, Asia retains 41 freshwater IAS fish under 14 families and Europe acquires 32 species under 18 families. The uppermost spreader IAS fish family is Cyprinidae followed by Cichlidae subsequently. Nine common fishes (Carassius auratus, Cyprinus carpio, Onchorynchus mykiss, Oreochromis mossambicus, Poecilia reticulata, Salmo salar, Salmo trutta and Salvelinusfontinalis) turned out invasive in all the continents (without Antarctica). Among IAS introduction pathways, aquaculture causes the highest percentage of freshwater IAS introduction in all continents. Aquaculture root 25% of IAS fish introduction in Africa, 21% in Asia, 19% in Australia, 20% in Europe, 19% in North America and 19% in South America. There is hardly any documentation on freshwater IAS fishes of Antarctica. Therefore, future research consideration may be designed.J. Environ. Sci. & Natural Resources, 8(2): 63-74 2015

Abstract:

Variabilities of biological communities in lower reaches of urban river systems are highly influenced by artificial constructions, alterations of flow regimes and episodic weather events. Impacts of estuary weirs on fish assemblages are particularly distinct because the weirs are disturbed in linking between freshwater and estuarine fish communities, and migration successes for regional fish fauna. This study conducted fish sampling at the lower reaches of the Nakdong River to assess spatio-temporal variations in fish assemblages, and effects of estuary weir on structuring fish assemblage between freshwater and estuary habitats. In total, 20,386 specimens comprising 78 species and 41 families were collected. The numerical dominant fish species were Tachysurus nitidus (48.8% in total abundance), Hemibarbus labeo (10.7%) and Chanodichthys erythropterus (3.6%) in the freshwater region, and Engraulis japonicus (10.0%), Nuchequula nuchalis (7.7%) and Clupea pallasii (5.2%) in the estuarine site. The fish sampled were primarily small species or the juveniles of larger species at the estuary region, while all life stages of fishes were observed at the freshwater habitats. The diversity patterns of fish assemblages varied greatly according to study site and season, with higher trends at estuarine sites during the warm-rainy season. No significant difference in diversity between freshwater and estuarine sites during the cold-dry season were found. Multivariate analyses of fish assemblage showed spatial and seasonal differences of assemblage structures. Higher effects of between-site variability but not within seasonal variability at each site were observed. Variations in assemblage structures were due to different contributions of dominant species in each habitat. Common freshwater species characterized the fish assemblage in the freshwater region, while marine juveniles were significantly associated with the estuarine habitat. The results from the ecological guild analyses showed distinct ecological roles for freshwater and marine species, and overlapping roles for fish sampled at the fishways. The lower reaches of the Nakdong River are an important ecosystem for both freshwater and marine juveniles. Nakdong River estuarine residents and migrant fishes, however, have been negatively affected by the construction of the weir (gravity dam), due to the obstruction to migration from and to freshwater habitats. Conservation and management policies aimed at minimizing anthropogenic influences on estuary ecosystems should focus on evaluating ecological functions of estuary weirs.

Abstract:

Abstract The published information on sublethal effects of untreated and biologically-treated bleached kraft mill effluents (BKME) on freshwater fish has been critically reviewed from a Canadian perspective. Despite the vast data base, a clear assessment of BKME effects to fish was difficult. Based on the available information to date, BKME discharges do not seem to cause serious sublethal toxic effects on fish at concentrations expected to be found in Canada's receiving freshwaters. Only the tainting of fish flesh (a non-toxic effect) has been identified to be a possible consequence of BKME discharges at certain dilution levels. In order to properly assess the effect of BKME, future studies should be aimed at identifying possible problems relating to fish tainting compounds, fish reproduction, early development and habitat alteration (e.g. colour, nutrients).

Abstract:

Human activities have a considerable impact on hydrographic systems and fish fauna. The present review on conservation genetics of neotropical freshwater fish reveals that DNA analyses have been promoting increased knowledge on the genetic structure of fish species and their response to environmental changes. This knowledge is fundamental to the management of wild fish populations and the establishment of Evolutionary Significant Units capable of conserving genetic integrity. While population structuring can occur even in long-distance migratory fish, isolated populations can show reduced genetic variation and be at greater risk of extinction. Phylogeography and phylogeny have been powerful tools in understanding the evolution of fish populations, species and communities in distinct neotropic environments. Captive fish can be used to introduce new individuals and genes into the wild and their benefits and disadvantages can be monitored through genetic analysis. Understanding how fish biodiversity in neotropical freshwaters is generated and maintained is highly important, as these habitats are transformed by human development and fish communities are increasingly exploited as food sources to sustain a growing human population.
