Abstract:
This study was undertaken to determine the effect of chronic exposure to sub-lethal concentrations of tannery effluent (TE) on the humoral antibody response and the cell-mediated immune response of the fish Cyprinous carpio. The LC(50) value of the TE for C. carpio was determined by bioassay to be 3.8%. Sub-lethal concentrations of TE (0.6% and 0.3%) significantly suppressed the humoral and cell-mediated immune responses. Exposure of C. carpio to the TE had a significant effect on mean acceptance time (MAT) for transplanted scales. MAT was found to be 5-8 days for autografts and 4-7 days for allografts. The somatic indices of the kidney and spleen were reduced compared with controls.
