The effect of heavy metals and mixture were studied on some haematological and biochemical parameters in fish, Cyprinus carpio at sublethal level over the period of 30 days. Heavy metal significantly decreased total RBC count, haemogoblin, heamatocrit (Hct) (except copper after 10 days exposure). The WBC count was increased significantly in all the treated(More)
Bioinsecticide Bacillus thuringiensis var. kurstaki (Btk) was used for controlling the mosquito species (Anopheles stephensi and Culex quinquefasciatus) which gave a significant (p<0.05) mortality in both species. The higher concentration of Btk was highly effective compared to the control ones. The controlling effect was dose and time dependent. Among the(More)
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(More)
The major carp, Labeo rohita were exposed to (0.873%) lethal and sublethal (0.073%) concentrations of tannery effluent for 24h and 40 days respectively under static bioassay condition. The surface architecture of gill revealed severe damages such as : fusion and clumping in the middle and distal parts of the primary lamellae, swelling and deterioration of(More)
