EFFECT OF CADMIUM ON ENZYMES OF LIVER OF GUPPY FISH

*Sabiha Khan

ABSTRACT

The acute toxicity of cadmium on enzyme activities of fish was evaluated under static conditions. The fish was constantly exposed to cadmium. Evaluation of toxic effect of cadmium on fish Lebistes reticulatus(Guppy) was carried out. Effect of sub lethal (LC50), 1/3rd and 1/9th LC50 concentrations at 15, 30 and 45 days of exposure was studied in target organs liver. Drastic change in the Acid phosphatase (ACP), Alkaline phosphatase (ALP) and Adenosine triphosphatase enzyme (ATPase) was observed. The enzyme ACP and ALP was elevated throughout the experimented period and the ATPase activity was inhibited along the experimental period at three different concentrations of cadmium.

Keywords: ACP, ALP, ATPase, Cadmium, Guppy.
