Effect of Nitrite on Oxygen Consumption and Ammonia Excretion of the Fresh Water Crab Paratelphusa jacquemontii (Rathbun)By B. S. Vijaykumar, Y. Narayanasamy, P. S. Paruruckmani, R. Archana
Abstract: In aquatic ecosystem, nitrite concentrations are elevated by pollution with nitrogenous wastes and imbalances in bacterial nitrification and denitrification processes. Nitrite is transformed by nitrification to nitrate under aerobic condition. The effects of nitrite on physiology were investigated in the fresh water crab, Paratelphusa jacquemontii (carapace length 4–5 cm and weight 50–70 g) for 96 h. The crabs were exposed to sublethal concentration (1/10th and 1/20th of 96 h LC50) …
