Abstract

Present investigation work Activity levels of Aspartate Transaminase (AAT) and Alanine Transaminase (ALAT) in freshwater fish Labeo rohita exposed to Deltamethrin. Aspartate and Alanine transaminases (AAT and ALAT) are widely distributed in the cells of all animals and serve to link the carbohydrate and protein metabolism, by interconverting dynamic substances. These two enzyme activity levels were estimated in lethal 1, 4 days and sublethal 1, 4 and 8 days concentrations in different tissues. In lethal concentrations activity was more than that of sublethal concentrations. Whereas in the sublethal concentration the increase of these parameters in the tissues of fish was more at day 4 and less at day 8 which was in the order 1 < 4 > 8 day. The activity levels were in order to gills > muscles > liver.
