Abstract:
Ammonia is present in the aquatic environment due to agriculture run-off and decomposition of biological waste. Ammonia is toxic to all vertebrates causing convulsions, coma and finally death. The focus is on this aspect and thus it was taken up in the present study. The effect of sub lethal concentration, namely 6 ppm of ammonia and 4.7 ppm of ammonia concentrations selected for fingerlings Catla catla and Labeo rohita respectively after evaluation of toxicity tests. The fingerlings were exposed to7days.Some metabolic components, namely ammonia, urea and glutamine estimated in the liver, muscle and brain tissues of Catla catla and Labeo rohita.
