This study analyses ammonia sources and paths of ammonia detoxication in fish. The deamination of amino acids is highlighted from the point of view of ammonia production with respect to histidin and serin, as well as to alternative ammonia sources in natural renewal of somatic tissues and cells. Simultaneously, non-existence of ureosynthetic cycle and change of outer environmental conditions can easily disrupt the balance of offer and excretion and lead to the accumulation of ammonia with symptoms of intoxication.
