Abstract

The present study indicates a brief account of the toxic effects of heavy metals on fish. Heavy metals are extremely hazardous for the health of fish. The sublethal toxicity of nickel chloride on protein content in gill and muscle of fish Labeo rohita have been studied. The fish exposed to sublethal concentration of 1/15th (low), 1/10th (medium) and 1/5th (high) of the 96 hour of the LC50 for the period of 10, 20 and 30 days. The results showed decrease in the protein content and increase in the amino acid content in gill and muscle of fish Labeo rohita. The significant reduction in protein content and elevated levels of amino acids are apparently indicative of the toxic effect of heavy metal nickel Chloride on biochemical parameter and organism’s response to the toxic stress.
