Effect of temperature on oxygen consumption and metabolic rate in Puntius sophore (Hamilton-Buchanan, 1822)
Journal Title: International Journal of Life Science - Year 2018, Vol 6, Issue 2
Abstract
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.
