Abstract In 2017, the base population of a family-based silver carp ( Hypophthalmichthys molitrix ) genetic improvement program was spawned in Bangladesh. This aims to improve growth rate under polyculture production systems, through direct selection on primary trait harvest-age weight. The objective this study quantify variation in, and correlations between, weight (assessed 8012 fish from 184...

Labeo rohita, Gibelion catla, Cirrhinus mrigala, Ctenopharyngodon idella and Hypophthalmichthys molitrix were grown together for 365 days in triplicate ponds. Six iso-caloric feeds having varying protein levels i.e. 22, 24, 26, 28, 30 and 32% were prepared and supplemented to fish at 2% fish weight daily. Significantly, higher final average weight (793 ± 197 g) and total length gain (398 ± 40 m...

A study was carried out on the optimal dose of inorganic fertilizer used in carp polyculture system over a period of 10 months. Three treatments were assigned: without inorganic fertilizer, with the application of 100 kg/ha/month inorganic fertilizer and 150 kg/ha/month inorganic fertilizer as T1, T2 and T3, respectively. Each treatment had three replications. The selected indigenous carp speci...

Heavy metals i.e. Copper (Cu), Zinc (Zn), Manganese (Mn), Iron (Fe), Cadmium (Cd), Nickel (Ni), Mercury (Hg) and Arsenic (As) were analyzed in 35 samples of the fish muscle, from East Kolkata Wetlands (EKW). The concentration of heavy metals was in order of, Fe > Zn > Cu > Mn > Ni > As > Hg > Cd. The essential metals, such as iron, zinc, copper and manganese were in higher concentrations and, t...
