Abstract: Sublethal toxicity of nickel-chrome electroplating effluent on blood plasma protein and cholesterol was investigated in the fish Channa punctatus(BI). The fish was most sensitive to stress during the spawning phase followed by preparatory and prespawning phase of the reproductive cycle.? An increase in the concentration of biomolecules corresponding to a decline in GSI clearly indicates that the metabolism of the fish is affected and the biomolecules are not taken up by the body under the stress of the effluent.

 

Key words: Blood plasma, Protein, Cholesterol, Spawning phases, Channa punctatus.
