Table 2 Mean and standard error (SE) values for plasma ammonia concentration and glutamine synthetase in liver and brain in Betta splendens exposed to sublethal ammonia concentrations (90 mM) for 96 h. Asterisks indicate a significant difference from the control value: *P < 0.05
From: Acute toxicity of ammonia and nitrite to Siamese fighting fish (Betta splendens)
