Heavy metals are regarded as hazardous to aquatic ecosystems because of their environmental persistence and their tendency for bioaccumulation. Enzymes are biochemical macromolecules that control metabolic processes of organism, thus a slight variation in enzyme activities would affect the organism. In the present study investigated the effect of lead (II) nitrate (6 ppm for 7 days) intoxicated liver tissue of fish Catla catla. At median lethal concentration of lead (II) nitrate (6 ppm for 7 days) treated, the whole liver tissue showed on decreased level of phosphatase activity (ACP and ALP) and simultaneously increased level of transaminase activity (GOT and GPT). The results strongly suggested that, the chosen concentration of lead (II) nitrate might be affecting the fish metabolism.
