Good aquaculture practice (GAP) based carp fattening is a potential technique to obtain higher and safe fish production within shorter period in ponds of drought prone area. Sustainability this technique, however, constrained by high feed cost poor water quality. Therefore, as an overcoming effort, three diets (protein content 20%, 25% 30%) under different treatments (T1, T2 T3) were tested dur...

Oxidative stress caused by various pollutants in water can be overcome different mechanisms aquatic organisms. Antioxidant enzymes play major role to minimize the hazardous effect of heavy metals fish. Superoxide dismutase is one antioxidant enzyme that converts superoxide radical into hydrogen peroxide (H2O2) and thus free radicals. Therefore, aim this research was evaluate activity (SOD) orga...

Feeding metabolism in an Indian major carp, Catla catla fingerlings of 10.8+0.56g was investigated in a flow-through water recirculating system. The metabolic energy loss in resting metabolism and feeding metabolism were determined by the indirect method of oxygen consumption followed by multiplication by suitable oxycalorific coefficient. This was done in four metabolic chambers of a respirome...

A study was conducted to determine the growth performance and bioaccumulation and tolerance of metal mixture toxins in five fish species including Labeo rohita, Catla catla, Cirrhina mrigala, Hypophthalmichthys molitrix and Ctenopharyngodon idella separately, under chronic exposure of metal mixture (Fe + Zn + Pb) at sub-lethal concentrations (1/3 of LC50) for 12 weeks period. Moreover, response...
