Effects of Exposure to Ammonia on Plasma, Brain and Muscle Concentrations of Amino Acids and Adenyl Nucleotides in the Siberian Sturgeon, Acipenser baerii

Neurological disorders appear extremely rapidly for elevated doses of ammonia in Siberian sturgeon baerii. To explain this phenomenon, the effects of ammonia during a 72-h exposure in control conditions and for a lethal and a sublethal doses were examined on the concentration of free amino-acids and adenyl nucleotides in the Siberian sturgeon plasma, muscle and brain.
