AKHTER ALI SIDDIQUI

The main objective of this study was to evaluate the acute toxicity of cadmium which is one of the most deleterious heavy metals in the aquatic fauna. The fresh water field crab, Barytelphusa gureini is an important human food source in different parts of India. Evaluation of the toxic effect of cadmium chloride on the experimental crab for the Lc50 value was carried out. The present study evaluates toxicity of cadmium chloride and its impact on the proteins of hepatopancreas, muscle, hemolymph, gills and gonads of the fresh water field crab Barytelphusa gureini. The significant role of cadmium chloride in the above organs of the experimental animal discussed and the results correlated with the findings of the earlier researches.
