ORIGINAL RESEARCH ARTICLE Effect of Aluminium Chloride on the Biochemical Changes in Different Tissues of the

The effect of Aluminium chloride on the freshwater fish Labeo rohita was assessed. Sub-lethal concentration (LC50) for 96 hours of exposure was found to be 32.5 ppm. The fishes were exposed to the experimental concentration 1/4th of Aluminium chloride for 96 hours. The estimated total proteins concentration in the tissues (kidney, gill, muscle and liver) were found to be (-3.48,-28.24,-36.85 and-38.36%) respectively, are found to be decreased. The estimated free amino acids concentration in the tissues (gill, muscle kidney and liver) were (4.18, 8.14, 10.78 and 11.64%) found to be increased during the exposure periods. The present results showed that variation in biochemical parameters which is an adaptive response of vertebrates due to sublethal exposure of Aluminium chloride
