Influence of NH3 in doses of 0.1-0.5 mg/dm3 on performance ability of the common bream was studied at 15 and 20°C using a method of burdening the fish with predetermined physical effort. The ergometric readings revealed, that within the range of 0.12-0.13 mg of NH3/dm3 there was no effect of ammonia on lowering the performance ability of the fish. Within the concentration range of 0.37-0.39 mg of NH3/dm3, at 15°C the value of work declined to 54% and at 20°C-to 22% of the respective values of control group.
