Abstract

The paper describes the changes in biochemical parameters of freshwater teleost, Cirrhinus mrigala (Ham.) when exposed to sublethal concentrations of leather dye Bismarck brown with three concentrations (0.6 mg/L, 0.7 mg/L, 0.8 mg/L) at different time intervals (24 hrs, 48 hrs, 96 hrs, 1 week). The serum total glucose showed decreasing trend on exposure to Bismarck brown at different time intervals and at all three concentrations. Under sublethal exposure to Bismarck brown the glucose level decreased in serum. The fall in the glucose content indicates its rapid utilization by the fish as a consequent of dye's toxic effect. The aim of the study is to aware the people to protect the fish fauna fromleather dyes and their effect on the biochemical parameters of the fish Cirrhinus mrigala (Ham.).
