Abstract
Indiscriminate and wide use of pesticides to wipe out pests, careless handling, accidental spillage of pesticides and pesticides released from manufacturing industrial units are carried by wind or percolate through water and finally washed down and find their way into water bodies, would equally affect non-target organisms like fish, which represent an important component of aquatic life and serves as a staple food for human beings. Hence, it is felt necessary to conduct toxicological studies which indicates the sequence of events in physiological and biochemical systems providing information on the nature and completion of compensatory mechanisms during toxic stress. The present investigation is aimed at estimating impact of Deltamethrin on Time course in the Indian major carp Labeo rohita. In the present study in relation to control the time course in rate of oxygen consumption initially elevated at 24hrs and declined thereafter at 7 and 15 days of exposure periods. Further towards the end of the 30th day exposure there was a rise in oxygen consumption from its early maximum suppression and came nearer to the control.
