Accumulation of chromium (Cr) was determined in water, sediment, aquatic plants, invertebrates and fish in aquatic ecosystems receiving effluents from handloom textile industries in Ranaghat-Fulia region of West Bengal in India. Cr was determined in the samples by atomic absorption spectrophotometer and data were analyzed functionally by Genetic Algorithm to determine trend of depositions of Cr...

The current study was carried out to optimize the dose of synthetic hormone for induction, and observe embryonic larval developmental in Gulsha, Mystus cavasius. Induced breeding conducted by using Ovupin (S-GnRHa) (each 1.5 ml vial contain 0.2 mg an analogue S-GnRHa) at four different doses i.e., 0.25, 0.5, 1.0- 1.50-ml kg-1 body weight (BW) females, half these were applied males. Among doses,...

A study was undertaken to determine the effect of different dietary protein levels on growth, survival and production Mystus cavasius (Hamilton-Buchanan 1822) with three experimental diets containing 29%, 32% 35% level applied simultaneously treatments T1, T2 T3 respectively each replications. The stocking density (1, 11, 150/ha), initial weight (3.00±00 g) length (2.00±0.00 cm) fish were same ...
