Abstract

In the present investigation freshwater fish Labeo rohita exposed to Deltamethrin in lethal 1, 4 days and sublethal concentration 1, 4 and 8 days to estimate activity levels of ammonia and urea in different tissues like gill, liver and muscle. The shift in the ammonia and urea level was greater magnitude in lethal concentration of Deltamethrin. Where as in sublethal concentration the activity of ammonia among the tissues, decrement was maximum in Gill (-54.3) followed by liver (-45.2) and muscle (-44.8). Activity of urea was relatively less among the tissues, increment was maximum in gill (+ 75.6) liver (+ 74.9) and muscle (+81.0) in lethal and sublethal concentrations of Deltamethrin. The increment was decreased with increasing exposure periods.
