title: Role of waterborne copper on survival, growth and feed intake of Indian major carp, Cirrhinus mrigala Hamilton.
abstract: The effect of copper on survival, growth and feed intake of Indian major carp, Cirrhinus mrigala (Hamilton) fry (0.92 +/- 0.28 g) was studied for 60 days. Survival rates of the fish exposed to control (0.02), 0.10, 0.15 and 0.23 mg L(-1) copper were 100%, 83 +/- 3%, 58 +/- 6%, and 50 +/- 4%, respectively. Average daily growth was significantly (p < 0.05) lower at 0.15 and 0.23 mg L(-1) of copper. There was almost no growth at 0.23 mg L(-1) of copper. Feed intake rates reduced significantly (p < 0.05) at all the copper treatments. The copper accumulation in the fish increased with increasing concentrations of the metal.
