Popis: | Ammonia tolerance of European sea bass (Dicentrarchus labrax) juveniles (1.1 ± 0.3 g) was investigated by a series of acute toxicity experiments at different salinity levels (10, 20 and 30 ppt) at pH 8.0 and temperature 22 °C. Oxygen consumption rates were also measured to determine the Standard Metabolism (SM) of the fish. The tolerance of the fish to total ammonia nitrogen (TAN) and unionized ammonia (NH3) increased significantly with increasing salinity levels. The safe level for European sea bass was estimated to be 0.4, 1.0 and 1.6 mg L−1 for TAN and 0.02, 0.04 and 0.07 mg L−1 for NH3 at 10, 20 and 30 ppt salinity levels, respectively. At any, each level, the SM of the fish increased with increasing TAN concentration (P |
