ABSTRACT
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 the cells. The interlamellar space was filled either with hyperplastic epithelial or mucous cells. Secondary lamellae lost their identity and appeared finger like in structure in the lethal concentration and necrosis was observed in the primary and secondary epithelium. Swelling of primary and secondary epithelial cells was evident in sublethal concentration.
