Changes in the level of transaminases in Indian major carp, Labeo rohita exposed to sublethal concentration of tannery and distillery effluents.
The activity of alanine aminotransferase (ALAT) and aspartate aminotransferase (AAT) of different tissues of fingerlings of Labeo rohita under the influence of two effluents has been studied. The alanine aminotransferase activity was increased over the control in different exposed periods of tannery and distillery effluent treatments. The alanine aminotransferase in the liver showed increased activity at different periods than that of the muscle, kidney, gill and brain (p < 0.001) (60.09%) over the control during the 40 days exposure in both the effluents treatments. The increased activity of alanine aminotransferase was highly significant (p > 0.001) in all the tissue in tannery and distillery effluents treatments. Similarly aspartate aminotransferase activity was increased over the control in all the treated tissues from 10 to 40 days exposure. But this increase, was not significant in the muscle tissue in distillery and tannery treatements after 10 days exposure. From 10 to 40 days, the activity was increased but a maxmum elevation was observed during 40 days, where the elevation was more in the liver, which was followed by muscle, kidney, gill, brain (brain < gill < kidney < muscle < liver).
