Fenvalerate induced biochemical changes in the selected tissues of freshwater fish, Cyprinus carpio.
Alterations in the levels of some biochemical and enzymological parameters in brain, liver and muscle tissues of Cyprinus carpio exposed to sublethal concentration (10 micrograms/liter) of fenvalerate for 6, 12, 24 and 48 hr were studied. Total, structural and soluble proteins were decreased, whereas the free amino acids and the activities of protease, aspartate aminotransferase and alanine aminotransferase significantly increased in fenvalerate exposed fish. It is also observed that the changes were more pronounced with an increase in the period of exposure. Within the tissues, the alterations in biochemical and enzymological parameters was in the following order: liver greater than brain greater than muscle. The possible roles of fenvalerate induced changes in the fish are discussed.
