The objective of the present study was to identify the degree of damage to the histological architecture of haemopoietic tissues viz., liver, anterior kidney and spleen in A. morar exposed to various sublethal concentrations (10%, 20% and 30% of LC50 value) of lindane for a period of 60 days. The exposed liver had distention of sinusoids, necrosis, vacuolation and degenerative process in the cellular architecture. Anterior kidneys manifested necrosis, tubular vacuolation, followed by total damage of the tissue. Spleen on the other hand showed deposition of haemosiderin pigments, necrosis, vacuolation followed by proliferation of melanomacrphage centres. Total degeneration of the splenic tissue was observed by the end of the experiment. The results of this histological analysis of various fish tissues indicate a direct correlation between insecticide exposure and histopathological disorders observed.
