Abstract


Fresh water crabs are economically important because crabs are used as an alternative source of food by the people from Aurangabad region. Heavy metal and their salts containing effluents are directly discharged into the aquatic environment by many industries from Paithan and Aurangabad region. Heavy metal pollutants are a major problem in aquatic environment because of their toxicity, their persistency and tendency to accumulate in organisms and undergo food chain amplification. In the present investigation acute toxicity test was carried out to determine the LC50 values (lethal conc.) of copper sulphate by using static bioassay method. The LC50 values for 24, 48, 72 and 96 hrs of exposure were recorded as 14.02, 13.56, 12.91 and 12.41 ppm respectively. In the present study the copper content in different body parts of fresh crab, B. guerini was studied. The copper content was found high in all the tissues as compared to control group. The observations in the present study showed marked variation. The highest concentration of copper encountered in gill. The order of metal accumulation in various tissues of the crab was gill> muscle> HP> ovary> Testis.
