Effect of vegetable oil factory effluent on the gonads of a freshwater teleost, Heteropneustes fossilis (Bl.) --a biochemical study.
The effects of three sublethal concentrations (5,10,15% v/v) of vegetable oil factory effluent on biochemical changes in the gonads (ovaries/testes) of a freshwater teleost were studied. The results reveal a significant decline in the total lipid, cholesterol, phospholipid, and glycerine levels, but an increase in the free fatty acid levels, both in the ovaries and the testes of H. fossilis, following 150 days (mid-January through mid-June) of exposure to 10% and 15% concentrations of the effluent. This decrease/increase in the biochemical parameters was more or less dependent on the concentration of the effluent. The functional significance of any decrease/increase in the biochemical parameter(s) has been discussed.
