Effects of aldrin on scrum and liver constituents of freshwater catfishClarias batrachus L.
The changes in total protein, total phosphorus, calcium and cholesterol contents wore observed in serum and liver of treated and control fishClarias batrachus L. Alerin caused more pronounced effect in liver than in serum. Values remained significantly low in liver of experimental fish than in control, while the serum constituents fluctuated widely. The variations observed in different values are explained as transfer or development of tolerance. A constant increase of cholesterol in serum corresponding to a regular decrease in liver is interpreted as deportation of cholesterol from liver to serum as a result of liver damage by aldrin poisoning.
