Two independent experiments were performed to determine the effects of salinity on survival and growth juvenile Macrobrachium rosenbergii, first one was median lethal (MLS-5096 h) second assess at different sub-lethal salinities under field condition. In MLS-5096 h study 0, 5, 10, 15, 20, 25 30 ppt used initially find out tolerance range. Accordingly, a definitive test done in next phase exact by directly transferring species 21, 22, 23, 24, 25, 26 27 for 96 h. The M. rosenbergii estimated...

Two independent experiments were performed to determine effects of salinity on survival and growth adult Channa punctata. The purpose the first one was median lethal (MLS-5096h) that second assess fish at different sub-lethal salinities under field conditions. 5, 10, 15, 18 20 g l−1 used initially range tolerance. After 100% mortality had been obtained in phase, a definitive tolerance test carried out next phase find by direct exposure species 10–18 for 96 h. estimated MLS-5096h C. punctata...

Ornamental fishes are the most popular pet throughout world and high demand for these has made them an important component of fish trade. India contributes a very meager percentage to ornamental trade; but considering ichthyofaunal diversity it potential compete with world’s leading producers in near future. Sundarban Biosphere Reserve abundant waterbodies rich diversity. Although some research been carried out on resources Sundarban; detailed documentation freshwater indigenous this region...

A breeding experiment on Pangasius sutchi was conducted from July 2008 to September in a hatchery West Bengal, India, using three different inducing agents, each injected at two dosages: carp pituitary extract (CPE) and synthetic hormones, Ovaprim Ovatide. The fertilization rate 82% 91%. Hatching took place within 34 36 hours the time of fertilization, with hatching 73% 79%. response spawning CPE best Ovatide terms percentage high rate, ease stripping.

Objective: To describe the parasitic infestations of Anabas testudineus (A. testudineus) collected from three different fish producing districts West Bengal state in India. Methods: A total number 75 specimens A. were floodplain areas Bengal, These examined for parasites using established techniques after measuring basic morphometric parameters. Results: 165 individual 20 (13 ectoparasites and 7 endoparasites) belonging to phyla recorded 64 infected testudineus. Among observed parasites, 8...

Salinity intrusion into coastal mainland or freshwater habitat because of recent climatic changes is exacerbating production risks and challenging the coping capacity fish farmers Sundarban delta in India. Hence, an experiment was conducted to evaluate survival growth performance certain commercially important brackish water species freshwater, subsequent low salinities (5 g l−1 10 l−1). Species like Scatophagus argus, Chelon parsia, Terapon jarbua, Etroplus suratensis, Penaeus monodon...

In this study, bacteriological quality of raw and processed Penaeus monodon produced for export trade from preprocessing, processing area cross-contaminated sample was analysed in terms total plate count (TPC), Vibrio cholerae, Escherichia coli, Staphylococcus aureus, Salmonella spp Listeria monocytogenes a HACCP (Hazard Analysis Critical Control Points) approved plant. all cases bacterial loads were highest crosscontaminated than the pre-processing area. E. coli present sample; however V....

The efficacy of the synthetic reproductive hormone WOVA-FH was evaluated for ovulatory performance and egg quality Clarias batrachus at three different doses, viz. 0.5, 1.0 1.5 ml/kg body weight brooder fish. After a 16-h latency period, both males females were simultaneously taken in ratio 1:1 milt collection stripping. Ovulatory parameters such as stripped quantity, spawning fecundity fertilisation rate highest (p < 0.05) 1 dose treatment followed by with 0.5 doses. stripping easy flowing...

The present communication evaluates salinity tolerance of two freshwater Silurid catfishes Clarias magur and Pangasianodon hypophthalmus (Order: Siluriformes) from coastal mainland Sundarban, India, where climate change induced intrusion is a persistent phenomenon.After 100% mortality all the fishes had been obtained 15 to 20 g l -1 levels in first phase range-finding test, non-renewal static toxicity bioassay was performed determine median lethal (MLS-50 96h ) for every fish by direct...

The present study investigated the effect of salinity on growth and survival Anabas testudineus for assessing their culture potential in brackish water. estimated median lethal concentration 96-hour A. (11.74 g) was 18.86 g l-1. Based concentration, performances were assessed at three sub-lethal levels. Highest obtained 5 l-1 followed by 0 l-1, 10 15 salinity. rate not hampered up to This implies that can be cultured considered as an ideal species promote Indian Sundarban delta where water...

Catla pieces of length 10-11 cm and thickness 1.0-1.5 were treated with brine spices. The fried at different temperature time like 120°C for 5 to 22 minutes, 140°C 4 12 160°C 3 10 minutes 180°C 2 minutes. effect variation in frying on weight loss, moisture content, loss pieces, amount exudate the can organoleptic characteristics canned fish studied standardize operation. highest (47.8%) was lowest (15.1 %) content 74.0% 57.5% recorded products respectively. same as that just opposite pieces....

Three ponds used for culture of Indian major carps adopting different management practices were investigated a period two years in Ganjam district Orissa (India). The fish growth, production, primary production varied significantly among three attributed to use levels inputs. Treatment with high stocking density and supplementary feeding regular liming intermittent fertilisation contributed maximum production.
