Biochemical compartmentation of fish tissues: chronic toxicity of mercuric nitrate on visceral phosphomonoesterases in Channa punctatus (Bloch).
Effect of sub-lethal dose of mercuric nitrate was studied in anterior, middle and posterior regions of kidney, anterior and posterior regions of left and right liver lobes, cephalic, thoracic and caudal regions of muscle and left and right gill tissues of C. punctatus in relation to acid and alkaline phosphatase under chronic studies. Middle region of kidney registered maximum rise and fall of acid and alkaline phosphatase, respectively. Right lobe of liver showed more rise and fall of acid and alkaline phosphatase activity respectively. Similarly, left gill is more pronounced than the right one. The observed enzymatic variations were discussed in relation to the biochemical constituents and physiological coordination rendered by these tissues.
