This review article briefly describes the structure of shrimps and the distinctive features of this decapod order (Decapoda). Various classifications of shrimps are considered: scientific (cold-water, warm-water, brackish, fresh-water); consumer (Atlantic or northern shrimp; king; tiger), for the size range (big, medium, small, especially small). Several types of shrimp are sold to the consumer: frozen, fresh-frozen, chilled, boiled-frozen, and canned. Frozen shrimps are subdivided according to the degree of cutting into: uncut; the neck in the shell; peeled while preserving the caudal fin and peeled. This article also provides an overview of the state of the resources of commercial invertebrates in waters of Russia.

Shrimp color is important when choosing the crustacean by the consumer. Pacific white shrimp Litopenaeus vannamei can convert various types of carotenoids into astaxanthin and accumulate them in its body, giving the desired reddish color. In this study, the shrimps were kept in a biofloc aquaculture system away from the coastal zone, fed with commercial feed supplemented with annatto extract (Bixa sp.). The experiment was carried out with a 2 x 4 factorial design with shad levels (50% and 80%) and four feeding regimes (0, 7, 14, and 21 days) to evaluate the most efficient model to promote the increase in the surface color of the shrimp. Leaching in artificial brackish water and the influence of biofloc pigments on shrimp color. According to the results, bixin sprinkled on the feed surface undergoes leaching in brackish water the measure of the time it is immersed. Carotenoids present in the biofloc showed a correlation with chlorophyll content by the R test. Raceway with 80% water shad and feed containing 1,235 mg/Kg of bixin showed the most significant results in the shell color of shrimps (fresh and cooked) and lower ammonia levels.

Aim: The present study aimed to investigate the shelf life of Pacific white shrimp (Litopenaeus vannamei) reared in inland saline water (ISRV) with those reared in natural brackish water (BWRV) during ice storage. Methodology: Freshly harvested L. vannamei shrimp cultured in inland saline water and brackish water were collected and biochemical parameters, microbial analysis and sensory parameters were evaluated for 21 days during ice storage with sampling interval of 3 days. Results: Total volatile basic nitrogen content increased up to 9th day in shrimps reared in BWRV and up to 3rd day in ISRV reared shrimps. Similarly, tri methyl amine content increased up to 3rd day for ISRV, there after the values decreased. The values of lipid oxidation such as peroxide value, free fatty acid and thiobarbituric acid reactive substance increased. Sensory scores for ice stored BWRV and ISRV showed a decreasing trend with increasing storage period. Interpretation: On the basis of microbiological parameters, pacific white shrimp (Litopenaeus vannamei) reared in brackish water and inland saline water can be ice-stored up to 12 days in fresh conditions, while other biochemical and sensory parameters are acceptable up to 18 days.

The sustainability of the shrimp aquaculture depends largely on disease control and the health status of shrimp. Probiotics, which make shrimps healthier and more resistant to pathogens, are promising countermeasure for shrimp diseases. In this study, the effects of the marine purple non-sulfur photosynthetic bacterium (PNSB) Rhodovulum sulfidophilum on Marsupenaeus japonicus (kuruma shrimp) growth and survival were examined in 177 m2 aquaria (140 tons of water) for 70 days. The shrimp received feed containing 0.01 % fresh weight (106 colony forming unit/g) of R. sulfidophilum cells. The survival rate significantly improved (P < 0.001) (R. sulfidophilum-fed = 81.9 %; control = 71.5 %), the feed conversion rate improved (R. sulfidophilum-fed = 1.83; control = 2.11), and there was no difference in the shrimp average body weight. The approximate bacterial cell cost was $0.003 to $0.005 per 1 kg feed, indicating that the R. sulfidophilum approach is economically feasible and a promising candidate for probiotic bacteria in shrimp aquaculture.

The increasing cultivation of Vannamei shrimp throughout the archipelago in theaquaculture area lately has made some farmers try to cultivate vannamei shrimp in freshwaterponds, and even exploring farmer groups in urban areas also try to cultivate vannamei shrimp infresh water by utilizing less productive land. Vannamei shrimp that have a high tolerance tosalinity, ie from 2 to 40 ppt, and will even grow quickly at lower salinity. The condition ofshrimp adapted to salinity then made some farmers try to cultivate vannamei shrimp in freshwater through an acclimatization process and successfully carried out shrimp farming at lowsalinity at 2 ppt salinity. Cultivation of vannamei shrimp in fresh water has several advantagesincluding: resistance to the risk of contracting shrimp disease caused by viruses and bacteria thatinfect many shrimp in brackish water. The aim of the activity is to improve the ability andcapacity of the group through counseling and training on how to make good shrimp farming sothat it can increase production efficiency and productivity and minimize the risk of failure ofvannamei shrimp farming. The approach method used to overcome the problems faced by theGotong Royong farmer group is by way of an ongoing participatory approach between theproposing team and partners, as the controller of the Community Partnership program which hasan active role in providing assistance and periodic guidance to partners. From the results of thisactivity the following conclusions were obtained: (1) Cultivation of vannamei shrimp(Litopenaeus Vannamei) on the grounds in the Mutual Cooperation Group was received withgreat enthusiasm, and asked to be accompanied from pond preparation, fry selection, frystocking, monitoring to harvest. (2) The key to the success of shrimp farming in freshwater inurban yards is the selection of fries adapted to fresh water and monitoring water quality andfeeding during cultivation.Keywords: Cultivation, Vannamei, Yard, Intensive, Mutual Cooperation

White shrimp (Litopenaeus vannamei) culture has grown rapidly in Indonesia since early 2000s. White shrimp have stronger resistance to WSSDV attacks, and are euryhaline. In it’s natural habitat, this shrimp was found in waters with a range of 0.5-40 ppt salinity. White shrimp grow optimally at 15-25 ppt salinity, even still suitable at 5 ppt salinity. This capability provides the opportunities to culture these commodities in inland water. White shrimp need inorganic elements or minerals for their living processes. Calcium is one of the main needs of shrimp that is closely related to the development and maintenance of skeletal systems and plays a role in some physiological processes of the body.The requirement for calcium in shrimp is increasing when it is cultivated in fresh water.This Internship aims to find out the technique of adding calcium carbonate (CaCO3) in feed, used for the white shrimp culture in fresh water. In this field practice, the addition of calcium carbonate in a level of 2% refers to the requirement of white shrimp for optimal growth. This was based on the calcium requirements of shrimp in the amount of 1-2%. The method was repelleting, by grinding feed and calcium using mortar and pestle, then filtered to get the smoothest part. Then mix calcium with 10 mL of water and mix it with pellets evenly. Then the mixture is air dried and mashed again and weighed according to the required dose of feed. The addition of calcium in the feed affects the growth of shrimp, because calcium is one of the most important anorganic mineral for the growth and development of exoskeleton, regulates blood clotting, heart rate, kidneys, nerves, the activity of several enzymes, and cell function

Shrimp is a type of crustacean biota that lives in fresh, brackish and marine waters. Giant prawns are also freshwater shrimp that have high economic value, and are a fishery commodity that is widely observed by local and foreign consumers. Consumer demand for shrimp commodities has experienced a shift towards meeting the need for live shrimp. One of the methods used in the process of optimally transporting shrimp is to perform shrimp anesthesia with the aim to maintain the fiological and morphological conditions of the shrimp, so that the shrimp is expected to arrive in a state of life by using green betel leaf extract. The design used in this study is complete randomized design (CRD) consisting of 4 treatments with 5 replications namely in the treatment of 1 immersion at a dose of 50 ml / 4 liters of water, 2 immersion treatment at a dose of 100 ml / 4 liters of water, 3 immersion treatment at a dose of 150 ml / 4 liters water and 4 immersion treatment with a dose of 200 ml / 4 liters of water. Based on the results of the study, it can be concluded that the difference in the dose of green betel leaf extract significantly affects the time of fainting and conscious time of giant prawns, the best dose that can be given to shrimp as an anesthetic during transportation dry system for ± 6 hours is treatment 4 namely with ex dose betel leaf powder 200 ml / 4 L water.

During the last few years, conflicts between agriculture and aquaculture have been an important issue in the Bac Lieu province, Mekong Delta, Vietnam. A large area of rice production has been converted to shrimp or shrimp–rice based production systems that require the intake of saline water into fresh water zones that have been used for agriculture. To manage this conflict, the provincial authorities have reviewed land use plans and identified a buffer zone with a mixed land use system of shrimp–rice (rice in the rainy season and shrimp in the dry season when sluices are opened). Under the CPWF (Challenge Program on Water and Food) Project No. 25, role playing games (RPGs) were applied for analyzing the land and water management strategy of farmers in the buffer zone. The RPGs organized in three villages (Phong Thanh, Ninh Thanh Loi and Vinh Loc) indicate that due to much higher revenue earned from shrimp compared with rice, farmers are attempting numerous techniques to prolong the duration of saline water in their fields for shrimp cultivation. This strategy makes the growing of a subsequent rice crop impossible even in the rainy season, thus requiring harmonization of water management at different levels (farm and canal systems). The results from these RPGs also indicate the need for further research on cultivation techniques for the shrimp–rice systems and on participatory methods to achieve better understanding of farmers' decisions.

Shrimp are crustaceans that live in the seas and some fresh water bodies. The properties of this seafood depend on the conditions where they were grown, since some are grown as aquaculture on special farms. Shrimp, like other inhabitants of sea waters, are capable of accumulating heavy metals, free radicals that cause cancer, antibiotics and other substances. This article describes a validated method for testing shrimp for residues of antibiotics from the nitrofuran and chloramphenicol group using the Randox bioluminescence method. Monitoring studies of 30 samples of boiled-frozen shrimp were carried out. At the same time, no antibiotics from the group of nitrofurans and chloramphenicol were found, which indicates the good quality of the supplied products.

A Comparative study was carried out to observe the response of Maize crop by using wastewater from shrimp processing industries at Rupsha Upazila under Khulna district during 2011-12. In the experiment, soil and water quality parameters were determined to sketch out the effect of growth and yield of Maize crop of the experimental area. The nutrient contents of water were analyzed for measuring pH, EC, salinity, sodium adsorption ratio (SAR), soluble sodium percentage (SSP), Hardness and some major ionic concentrations. For industrial wastewater, the average pH was 8.12 which reflected alkaline in nature. The values of SAR, SSP and Hardness were 4.28, 71.24 to 81.847 percent and 298.8 mg L-1 and for soil, the pH, EC and other major ionic concentration were determined and the value of wastewater irrigated soils was shown higher than the value of freshwater irrigated soils except magnesium. Loading of soil was not much higher except Na. For plant response, Plant height was significantly different from fresh water irrigation as well as leaf response was shown on average same results and moisture content of grain has indicated that yield was harvested at right time with yield response was moderately good in compare with fresh water. If proper management can be implemented for recycling this wastewater, then this wastewater can be used for sustainable production of maize crops.

The high freshwater consumption requirements in shrimp biorefinery approaches represents one of the major drawbacks of implementing these technologies within the shrimp processing industry. This also affects the costs associated with the plant operation, and consequently, the overall economic performance of the project. The application of mass integration tools such as water pinch analysis can reduce frewshwater consumption by up to 80%, contributing to shrimp biorefinery sustainability. In this work, the economic evaluation and the techno-economic sensitivity analysis for a mass integrated approach for shrimp biorefinery were performed to determine the economic feasibility of the project when located in the North-Colombia region and to identify the critical techno-economic variables affecting the profitability of the process. The integrated approach designed to process 4113.09 tons of fresh shrimp in Colombia reaches a return on investment (%ROI) at 65.88% and a net present value (NPV) at 10.40 MM USD. The process supports decreases of up to 28% in capacity of production and increases of 12% and 11% in the cost of raw materials and variable operating costs without incurring losses, respectively. These findings suggest that the proposed design of the water recycling network coupled to a shrimp biorefinery approach is attractive from an economic point of view.

ABSTRACTVibrio parahaemolyticusis a seafood-borne pathogenic bacterium that is a major cause of gastroenteritis worldwide. We investigated the genetic and evolutionary relationships of 101V. parahaemolyticusisolates originating from clinical, human carrier, and various environmental and seafood production sources in Thailand using multilocus sequence analysis. The isolates were recovered from clinical samples (n= 15), healthy human carriers (n= 18), various types of fresh seafood (n= 18), frozen shrimp (n= 16), fresh-farmed shrimp tissue (n= 18), and shrimp farm water (n= 16). Phylogenetic analysis revealed a high degree of genetic diversity within theV. parahaemolyticuspopulation, although isolates recovered from clinical samples and from farmed shrimp and water samples represented distinct clusters. The tight clustering of the clinical isolates suggests that disease-causing isolates are not a random sample of the environmental reservoir, although the source of infection remains unclear. Extensive serotypic diversity occurred among isolates representing the same sequence types and recovered from the same source at the same time. These findings suggest that the O- and K-antigen-encoding loci are subject to exceptionally high rates of recombination. There was also strong evidence of interspecies horizontal gene transfer and intragenic recombination involving therecAlocus in a large proportion of isolates. As the majority of the intragenic recombinational exchanges involvingrecAoccurred among clinical and carrier isolates, it is possible that the human intestinal tract serves as a potential reservoir of donor and recipient strains that is promoting horizontal DNA transfer, driving evolutionary change, and leading to the emergence of new, potentially pathogenic strains.

ABSTRACT Many previous studies of oil toxicity used high oil concentrations and water soluble fractions (WSF). The aim of this study was to approximate field conditions, in which weathering and chemical dispersions reduce the volatile fractions of spilled crude oil. The objective was to determine the extent of toxicity reduction produced by decreased concentrations of monoaromatics and diaromatics. The study measured the relative toxicity of fresh Prudhoe Bay crude (PBC) oil and two distillation fractions (Stage I and Stage II) and their chemical dispersions to the shrimp Pandalus danae and the fish Ammodytes hexapterus (sand lance). The hydrocarbon composition of the three oils, the WSF of the oils, and the chemical dispersions were measured. Distillation of fresh PBC oil produced a Stage I oil containing very low amounts of monoaromatics (benzene and alkylbenzenes) but with the diaromatics relatively unchanged. Further distillation produced a Stage II oil which contained only higher molecular weight aromatics of three rings (phenanthrenes) and greater. Saturate hydrocarbons with corresponding boiling points also were removed. Bioassays on shrimp with dispersed oils showed that the removal of monoaromatics (Stage I) reduced toxicity about sevenfold. The WSF of Stage I oil and both WSF and dispersions of Stage II oil were not toxic to shrimp. Toxicity from fresh PBC oil WSF and dispersions was likely the result of the combination of monoaromatic and diaromatic compounds. Sand lance (Ammodytes hexapterus) mortality did not correlate with the aromatic content of the oils, but appeared to be affected by dispersed oil droplets of all three oils to about the same degree. The fish were more resistant to dispersed oil than the shrimp (higher toxicity index). However, when latent mortality is considered, the data show that the fish may be more sensitive than shrimp to dispersed oil.

This study describes the reproductive cell development and ovarian developmental stages, and identifies the nongerminal components of white shrimp (Penaeus schmitti) caught off the southern coast of Espírito Santo, Brazil. P. schmitti specimens were collected monthly from March 2019 to February 2020, by artisanal fishing. All shrimps were analyzed macroscopically (n = 181) and females were randomly selected monthly (n = 154) for ovarian histological analysis. The ovaries were extracted for visual analysis and then submitted to histological analysis. Macroscopic analysis determined five stages of gonadal development from the color and turgidity of the fresh ovary. Histological observations allowed us to observe five stages of gonadal development: immature, initial development, advanced development, mature and spawning. This information are fundamental for understanding the reproductive aspects of P. schmitti, as well as other penaeid shrimps, in order to promote preservation of natural stocks and provide information to assist in the development of the reproductive potential of native species in captivity.

This study aimed to investigate the removal of ciprofloxacin and norfloxacin from shrimp pond sediment during composting process with different antimicrobial concentrations. The results showed that after 40 days of composting, temperature varied from 25 to 55 oC. The highest temperature was on the day 20th. The pH values reduced along with composting time from weak base to neutral. During the composting processes, the removal efficiency of norfloxacin found in the range of 32.5–87.5 % depends on the initial antimicrobials concentrations. For ciprofloxacin, after 20 days of composting, the removal efficiency obtained was around 55 and 45 % and pH was 8.5 and 5.0. Salinity significantly affected ciprofloxacin removal that created remarkably efficiency reduction of ciprofloxacin in salty water as compared to fresh- and brackish water. However, no differences in removal efficiency of norfloxacin were observed between fresh and brackish water. The composted fertilizer was dark brown in color and odorless, contained 15.7-18.8 % C; 2.05 – 2.15 % N; and C/N ratio was 7.5–10.95. This indicated that compost fertilizer was completely decomposed.

16th February 2015. Due to a number of missing tables and figures, this article (DOI: http://dx.doi.org/10.3329/jesnr.v7i1.22144) was withdrawn from Vol.7(1) and has been republished with corrections in Vol.7(2) pp.177-184 (DOI: http://dx.doi.org/10.3329/jesnr.v7i2.22228).An investigation was carried out on the fish marketing system and availability of fish species at Daulatpur fish market in Khulna over 12-months from September 2012 to August 2013. Combinations of the participatory, qualitative and quantitative methods were used for questionnaire interviews for data collection. A total of 115 species of fresh water, brackish and marine water fish and crustacean species were identified during the observation period. The number of fresh water fish species was found 60 including 14 fresh water culture species and 12 SIS whereas brackish and marine water species was found 41 and crustacean species was 14 including 5 fresh water prawn, 6 marine and brackish water shrimp and 3 crabs. During the observation period, it was found that the availability of culture fish species was higher in the market and it was 55.86% including 17% catfish, 15.65 % tilapia, 15.56 % carp fishes, 4.18% koi, 2.47% punti and 1% prawn. Catfish, carps, tilapia, snakehead, baim, shing-magur, punti, koi etc were the major abundant groups among the fresh water fish species whereas ilish and some shrimp were the abundant species of marine and brackish water fish. The highest abundance (55.86%) was found the fresh water culture fish species following to marine and brackish water species (28.01%) and fresh water capture species (16.01%). The market chain from farmers/fishermen to consumers encompassed mainly primary, secondary and retail markets involving local agents (foria and bepari) suppliers, aratdars, wholesalers and retailers. During the observation, it was found that the auctioneers get 3 to 5% commission by performing their activities. Aratdars also get 4 to 5% commission due to arrange auctioning activities and providing other facilities such as clean water supply, electricity, space, communication etc which is called aratdary. In some cases farmers have to pay market tools that locally called khazna which vary from 5 to 10% depending on amount of sales. Market structure, species quality, size and weight have an influence on the price of fish and it was found that the price of fish increases per kilogram with increasing size and it varied with species to species. Every step of intermediaries of marketing channel obtained certain amount of profit and ultimately the farmers/fishermen received an average near about 60 percent of the retail price of fish in the market.DOI: http://dx.doi.org/10.3329/jesnr.v7i2.22228 J.

The protective effects of phosphorylated trehalose on the quality and characteristics of peeled shrimp (Litopenaeus vannamei) were determined. Quality changes in treated samples were evaluated by assessing the physicochemical properties of myofibrillar proteins (MP) and compared to fresh water-, sodium tripolyphosphate-, and trehalose-treated samples during 12 weeks of frozen storage. The sensitivity of MP to oxidation and denaturation was increased during frozen storage. Phosphorylated trehalose significantly improved the quality of shrimp by increasing water-holding capacity. Further analysis showed that the addition of phosphorylated trehalose reduced the decrease in soluble MP content, Ca2+-ATPase activity, and total sulfhydryl contents and also effectively inhibited the increase in the surface hydrophobicity of MP. In addition, atomic force microscopy and hematoxylin and eosin staining revealed that phosphorylated trehalose preserved the integrity of the myofibril microstructure. Thermal stability results further confirmed that the denaturation temperature and denaturation enthalpy of MP were improved by phosphorylated trehalose. Overall, phosphorylated trehalose suppresses the denaturation of MP in peeled shrimp during long-term frozen storage.

Abstract This study aimed to examine the effect of different concentrations of mangrove leaf S. alba extract which has been challenged with WSSV on the mortality rate of tiger shrimp P. monodon. The plastic container filled with 30 L sterile seawater salinity 30 ppt stocked with 10 pcs of tiger shrimp 15 g in size. Six concentrations of mangrove extract were tested; A). 0.01%; B). 0.1%; C). 1%; D). 10%; E). 100%. F). control (shrimp injected with WSSV suspension without mangrove extract). Each treatment with three replications. The WSSV suspension was mixed with mangrove extract (from boiling 1 kg of fresh leaves of S. alba in 5 L of water cooked to 2.5 L) according to the treatment with a ratio of 1:2 and incubated at a temperature of 29 oC for 3 hours. Then the mixture is injected into tiger shrimp by intramuscular as much as 100 μL/shrimp. Tiger shrimp mortality was observed daily, while total hemocytes, ProPO, and differential hemocytes were observed at the end of the study. The results showed that on the first day, the mortality of tiger shrimp was highest in treatment E and lowest in treatments A, and F(control). However, from the second day until the seventh day (the end of the study), the mortality of tiger shrimp was highest in treatment A and lowest in treatment C. The results of this study showed that the concentration of extract of S. alba 1% is most effective in inactivating WSSV, therefore tiger shrimp mortality can be reduced.

Probably as a function of their wide geographical distribution, the different population of Macrobrachium amazonicum shrimp may present distinct physiological, biochemical, reproductive, behavioral, and ecological patterns. These differences are so accentuated that the existence of allopatric speciation has been suggested, although initial studies indicate that the genetic variability of populations happen at an intraspecific level. Among the biological responses described for M. amazonicum populations, those regarding osmoregulation and metabolism play a key role for being related to the occupation of diverse habitats. To this effect, we investigated osmoregulation through the role of free amino acids in cell volume control and metabolism, through oxygen consumption in larvae (zoeae I, II, V and IX) and/or post-larvae of a M. amazonicum population from Amazon, kept in aquaculture fish hatcheries in the state of São Paulo. The results add information regarding the existence of distinct physiological responses among M. amazonicum populations and suggest that possible adjustments to metabolism and to the use of free amino acids as osmolytes of the regulation of the larvae and post-larvae cell volume depend on the appearance of structures responsible for hemolymph osmoregulation like, for example, the gills. In this respect, we verified that zoeae I do not alter their metabolism due to the exposition to fresh or brackish water, but they reduce intracellular concentration of free amino acids when exposed to fresh water, what may suggest the inexistence or inefficient performance of the structures responsible for volume regulation and hemolymph composition. On the other hand, in zoeae II and V exposed to fresh and brackish water, metabolism alterations were not followed by changes in free amino acids concentration. Thus it is possible, as the structures responsible for osmoregulation and ionic regulation become functional, that the role of free amino acids gets diminished and oxygen consumption elevated, probably due to greater energy expenditure with the active transportation of salts through epithelial membranes. Osmotic challenges also seem to alter throughout development, given that in zoeae II oxygen consumption is elevated on brackish water of 18, but in zoeae V it happens in fresh water. After M. amazonicum metamorphosis, free amino acids begin to play an important role as intracellular osmolytes, because we verified an increase of up to 40% in post-larvae exposed to brackish water of 18. The main free amino acids involved in cell volume regulation of ontogenetic stages evaluated were the non essential ones: glutamic acid, glycine, alanine, arginine, and proline. Interestingly, larvae from estuarine population studied here survived until the zoeae V stage in fresh water, but in some populations far from the sea, zoeae die right after eclosion in fresh water or they do not reach zoeae III stage. In addition, given that in favorable conditions caridean shrimp larvae shorten their development, we may infer that the cultivation environment, in which larvae developed in the present work, was appropriate, because almost all zoeae VIII kept on brackish water underwent metamorphosis directly to post-larvae and did not go through zoeae IX stage.

Attenuators of salt-stress favor the use of effluents, being a low-cost organic product. The present study aimed to evaluate the effect of vermicompost leachate (VL) added to shrimp-culture effluent on seeds and seedlings of Salicornia bigelovii (Torr.) under salt-stress, evaluating germination, water relations variables, and biomass. Seeds were irrigated with distilled water (DW) (CE: 0.0027 dS m−1), freshwater (FW) (CE: 1.36 dS m−1), seawater (SW) (CE: 55.83 dS m−1), shrimp residual water (SRW) (CE: 59.85 dS m−1), and with the same water sources but adding VL in 1:20 v/v. The means for the index of germination rate (IGR), germination energy (GE), and germination time (MGT) were higher with DW, DWVL, FW, and FWVL, decreasing with the others (p ≤ 0.05). In seedlings, the lowest water potential (Ψw) and osmotic potential (Ψs) were observed with SW, SWVL, SRW, and SRWVL (p ≤ 0.05), evidencing higher stress but the highest relative water content (RWC). The fresh and dry biomass increased and showed significant differences with SRW, and adding VL (DWVL, FWVL, SWVL, and SRWVL) acted as an effective attenuator of salt-stress. The response of water relations variables suggested an osmotic adjustment for mitigating the salt-stress in seedlings, lowering the Ψw and Ψs but increasing the RWC.

The present study was designed to assess the farming patterns and farmers livelihood in coastal regions of Bangladesh. Three coastal districts namely, Khulna, Satkhira and Bagerhat located in the southwest of Bangladesh were selected to conduct the study. Fifty shrimp farmers from each district (a total of 150 farmers) were selected for necessary data collection on the basis of farm size category (i.e., small, medium and large) following stratified random sampling technique. Descriptive statistics like sum, average, percentages, etc. were derived and calculated for analyzing the data. It was found that the farming system of coastal region was mainly shrimp based. The amount of land devoted to agricultural crop cultivation was declined due to shrimp cultivation for all categories of farmers. Number of livestock except poultry and duck was decreasing due to shortage of feed. Native fish species in fresh and open water bodies were also disappearing gradually. Lower crop production was observed through surveyed region due to lower productivity of land caused by salinity. However, shrimp cultivation opened up new avenues for employment for the local people especially for women. Small farmers get higher proportion of income (75.0% of total farm income) from shrimp farming than medium (67.4%) and large farmers (73.6%). On an average, farmers income was increased which enhanced overall socioeconomic condition and livelihood status. In spite of various adverse impacts of shrimp farming, it can be recommended that proper planning, regulation and motivation of the farmers are needed to develop an environment friendly shrimp farming as well as to maintain sustainable agricultural production practices in the coastal regions of Bangladesh.DOI: http://dx.doi.org/10.3329/pa.v24i1-2.19177 Progress.

Neocaridina davidi (Bouvier, 1904) is an exotic freshwater shrimp originating from Asia and often kept as a pet in amateur aquarium cultures. Herewith, we report on the second finding of N. davidi in fresh waters of Europe and the first discovery of that species both in Poland and in Central Europe. The species was found in samples collected in 2003, 2013 and 2017 in the thermally polluted canal connected to the River Oder, south of Gryfino, in the vicinity of the Dolna Odra Power Plant. The taxonomic identity of the collected shrimp was confirmed by the standard DNA barcoding procedure, using a 610 bp-long fragment of cytochrome oxidase I (COI). The findings spanning more than a decade suggest that N. davidi may have established a self-reproducing population at this site. Following the finding of Atyaephyra desmarestii (Millet, 1831) in 2000, Neocaridina davidi is the second freshwater shrimp species found in the River Oder and in Poland.

The objective of the experiment was to determine the best type of algae for growth, survival rate and the metamorphosis time of white leg shrimp larvae. The experiment consisted of five treatments: dried Spirulina sp. (NT 1), fresh Chaetoceros sp. (NT 2), fresh Thalassiosira sp. (NT 3), Thalassiosira sp. in concentrated form (NT 4) and Thalasiosira sp. in paste form (NT 5). The larvae at Nauplius VI were stocked in 0.5 m3 tank at the stocking density of 200 inds/L. The care regime was applied according to the popular process at the National Breeding Center for Southern Marine Aquaculture. After 10 days of stocking, the water parameters in all treatments were in a suitable range for the growth of larvae. The larvae in NT 4 showed the best body length, survival rate, metamorphosis time and were significant difference compared to the remaining treatments (P < 0.05). Whereas NT 5 was not significantly different (P > 0.05) compared to NT 2 in body length and NT 3 in metamorphosis time. NT 1 showed the worst these characteristics to the other treatments. In general, the use of concentrated Thalassiosira sp. for rearing white leg shrimp larvae gives good results, which should be commonly applied.

Developing shrimp to a commercial size in a confined freshwater space is important because it saves food and because predators and diseases are avoided. Our study was conducted to calculate the growth of white shrimp Litopenaeus vannamei by hyper-intensive farming in fresh water from 0,5 to 5‰ and under semi-controlled conditions. We seeded at a density of 563 postlarvae/m3 or m2 during the first cycle and 400 postlarvae/m3 in the second cycle in an outdoor pond of 6m3 or m2 covered with a mesh. Aeration was constant, they were fed Daphnia magna during the first two weeks and then camaronina pellets containing 35% protein, in food baskets, as demanded. The temperature ranged from 22,3 to 31,3°C, pH between 7,5 and 8,7, the oxygen was 4,26±1,43mg/L; the ponds were cleaned of debris every other day, and water was changed according to a program. The food conversion factor (FCA) was 1:1,1. The shrimp were measured weekly to calculate growth using the Bertalanffy model. Survival in the first cycle was 88,1 and 95,8% for the second cycle. Population parameters by maximum likelihood method of the first cycle were k=0,0957, L∞ =146,98 and t0=-0,93; in the second cycle k=0,0172, L∞ =367,82 and t0=-4,60. The results indicate rapid growth during the first ten weeks. Biomass was obtained from 26kg for the first cycle and 16kg for the second cycle.KEY WORDSGrowth, density, survival, biomass, semi-controlled conditions.

A method was developed for commercial scale production of chitin and chitosan in Bangladesh from marine shrimp, P. monodon and freshwater prawn, M. rosenbergii shell and appendages. Chitin is a macro-molecular linear polymer of anhydro N-acetyl glucosamine (N-Acetyl, 2-Amino 2-Deoxy DGlucose) and chitosan is deacetylated chitin. For production of chitin, fresh shells of P. monodon having initial bacterial load of >105 CFU/g sample and peroxide values of >10 mmol free iodine liberated /kg of oil were washed with dilute sulfuric acid. Adhered proteins were removed by washing with low strength alkaline solution and then rinsed with water. Crude chitin thus prepared was treated with concentrated hydrochloric acid and purified chitin was obtained after treating with low strength alkali solution. Water soluble chitosan was prepared by performing a deacetylation process using 50% NaOH (w/w) at 100oC for 4-5 hours and then washed, dried and ground. For purification of chitin and chitosan, a series of experiments were conducted to optimize the level of NaOH concentration and time and temperature schedule of demineralization and deproteinization/deacetylation. A high temperature-short time schedule obtained best quality chitin and chitosan. Both subjective and objective methods were used for the testing of quality and purity of chitin and chitosan. Comparative studies between the quality of products from different components of the shell and from different shrimp/prawn species showed that both chitin and chitosan obtained from M. rosenbergii shell were better compared to those of P. monodon in terms of extractability, deacetylation, and color. Shells obtained better product compared to shrimp appendages. The study suggests that chitin and chitosan can be produced in existing shrimp/prawn processing plants of the country with the simple renovation.J. Bangladesh Agril.

Shrimp farming plays a key role in economy of many countries all over the world. Unfortunately, a disease called Acute Hepatopancreatic Necrosis Disease (AHPND) or Early Mortality Syndrome (EMS) caused by Vibrio parahaemolyticus spreading from Asia to Central America costs shrimp industry billions of dollars annually. In the past few years, scientists from multi-disciplinary field collaborated to find out a solution for this disease. Until now, there are not any effective approaches to prevent and cure this disease. However, co-culturing shrimp with tilapia was carried out to limit the outbreak of AHPND in farm scale in many countries. Some previous studies also mentioned the benefits of this farming method to prevent other pathogens. The aim of this research is to determine whether intrinsic factors or cultured water of tilapia play role in inhibition of V. parahaemolyticus – pathogen causing AHPND. These factors include: mucus on tilapia gill and skin, tilapia fecal material, and microbiota or dissolved chemicals in culturing of tilapia. Anti-V. parahaemolyticus activity of tilapia (Oreochromis niloticus) fresh and overnight incubated feces and mucus were tested using agar well diffusion method. The effectiveness of feces and mucus inhibition was not clear, both of samples generated a weak inhibition on V. parahaemolyticus. Determination of V. parahaemolyticus inhibiting factor of tilapia cultured water using challenge test showed that dissolved compounds (smaller than 0.22 µm) inhibited the growth of V. parahaemolyticus. The presence of these compounds in tilapia-cultured water reduced V. parahaemolyticus to 17 times lower than that of the negative control with the seawater alone within the first three hours post challenge.

Abstract To date, lobster aquaculture relies on fresh food for feeding; however, the availability of fresh food is limited and its excessive use causes environmental degradation. Therefore, formulated diet is required to establish sustainable lobster aquaculture. Concerning this issue, this study was carried out to assess the growth and survival of spiny lobster Panulirus homarus fed fresh food and formulated diet. The study was conducted in a completely randomized design (CRD) with 3 groups of treatments and 3 replicates for each treatment. Feeding experiment was performed in a flow-through water system using 9 fibre tanks, 4000 L in volume. Each tank was stocked with 40 lobsters, with initial weight of 78.08 ± 0.22 g. Each group of lobsters was fed with fresh food (A), formulated diet (pellet) (B) and a combination of pellet and fresh food (C). The fresh food was a mixture of fish, crabs, shrimp and small mussel (3:1:1:1). Feeding experiment was done for 15 weeks. Results of the experiment showed that the highest specific growth rate of lobster was obtained from lobsters fed with the combination of pellet and fresh food (0.52 ± 0.02 %/day) and the lowest growth was resulted from lobsters fed formulated diet (0.16 ± 0.03 %/day). In contrast, the highest survival was achieved in lobsters fed formulated diet (51.67%). Whereas the lowest survival was found in lobsters fed fresh food (10%). This study indicated that good growth of lobster was resulted from feeding with formulated diet combined with fresh food, while good survival was supported by feeding with formulated diet.

This in order to test the effect of food on growth and fecundity, two kinds of food have been used the algae Scendesmus quadricaudae and fresh water shrimp powder. For two generations, growth and productivity have been followed up. The fresh water shrimp has been noticed as a food better than algae, because it caused recording, for the two generation higher length rate for the weeks of experiment. The individuals length rate at the end of the forth week reached 9.35 and 9.48 mm for the first generation and second generation respectively. The average length weekly increase rate for the first and second generations individuals feeding on dried shrimp was higher through the first and second week compared to what was recorded when feeding algae. The results showed that the fecundity of the individuals feeding on dried better than those feeding on algae. These individuals got matured in about 15 – 18 days old for the first generation and about 16 – 18 days old for the second generation s. Broods number for the two generation was four; the resulting generation was as nuplii larvae. The average number of the generation nauplii was 55.53, 61.20, 16.13 and 57.73 nauplii per mother for the four broads respectively. The average number of the second generation was 56.56,58.10,61.73 and 49.96 nauplii per mother for the four broods respectively . The individual feeding on algae S. quadricaudae recorded length rate of 7.32 and 7.43 for the first and second generation at the end of the forth week . the individuals got matured in about 19-21mm days old for the first generation and about 18-20 days old for the second generation . The first brood appeared in about 25 – 27 days old for the first generation, and about 30 – 35 days old for the second generation. The brood number was two for the first generation, the first one as nauplii larvae with a rate 40.26 larvae per mother and the second as cyst with a rate 27.90 cysts per mother. For the second generation individuals, one brood has been appeared from which the resulting generation was as cysts with a rate of 45.66 cysts per mother.

This paper assesses the risk of acidification of the organic shrimp model certified by Naturland at Tam Giang commune, Nam Can district, Camau province. Pond water and sediment was sampled in 8 ponds in March, July and November 2015, dike soil and mangrove soils were sampled in March 2015. Pond sediment and mangrove soils are highly reduced (Eh of top sediment and soils to 60 cm depth range respectively from -299 – -1mV and -321 – -52mV). Pond water ranges from neutral to slightly alkaline (pH of pond water 7.01-8.82) and sediment from slightly acidic to slightly alkaline (pH of fresh sediment 6.05-7.64, pHH2O 6.63-7.78, pHKCl 6.35-7.43). Mangrove soils show a large pH range with very low minimums (pHH2O 3.72, pHKCl 3.05), reconfirming the presence of pyrite mineral in the soil profile. Mangrove soils deposited on the dikes (partly oxidized) are very acidic (pHH2O 2.51±0.72, pHKCl 1.81-2.14, exchange acidity 11.56±2.69 meq/100g). At the start of the wet season, pH of pond water reduces sharply as a result of reception of acidic components from the oxidized pyritic material (FeS2) on the dikes. The exchange acidity in pond sediment and mangrove soils are negatively correlated with organic matter, indicating that the decomposition of organic matter under reduced conditions contributes to exchange acidity in pond environment. Risk of acidification of the organic shrimp model is high due to managerial activities (mostly channel digging and disposal of pyrite-containing mangrove soils on the dikes).
