Experiments were conducted to evaluate the oxygen demand of Puntius sophore   under   various   conditions,   with   reference   to   temperature   variations and oxygen concentrations. The oxygen requirements at different age   groups   have   also   been   studied   in   the   laboratory.   The   oxygen consumption and metabolic rates were studied at every 5°C, varying temperatures from 15-40°C. The fishes were inactive and the metabolic rate was minimal at 15°C, with an increasing temperature the activity of the fish changed and resulted more oxygen consumption. The fishes were found to be active at 25-30°C range of temperature. At the temperature above 35°C was not comfortable, since the fishes were erratic and behavior was not normal. At the ranges 15-40°C the difference in consumed dissolved oxygen of small size and large size fishes are very significant, The percentage increases at every 10°C in metabolic rate at the range of 15-25°C, 25-35°C, 20-30°C and 30-40°C is not uniformly double with increase in temperature. It was observed that the metabolic rate in small size fishes (0.74- 0.92 g) fishes are not coincide with the Vant Hoff’s hypothesis, where as 1.63g, 2.20g and 4.14 g. weight fishes, the metabolic rates were observed nearly doubled.

Key words: Oxygen consumption, Metabolic rate, Temperature, percentage, Vant Hoff’s hypothesis
