    EFFECT OF SUBLETHAL CONCENTRATION OF SHEA BUTTER EFFLUENT ON THE ARCHITECTURAL LAYOUT OF SELECTED ORGANS OF CLARIAS GARIEPINUS

    ABSTRACT Post Juvenile African catfish (Clarias gariepinus) were exposed to sublethal concentrations of shea butter effluent (0.003, 0.005, 0.007, 0.009 and 0.011 ppt) for 96 hours (acute) and 14 days (chronic). Control fish were maintained for the same periods in clean water devoid of shea butter effluent. Liver, Gill, Heart, Kidney and muscle samples from 3 fish were prepared for histological analysis and examined for alterations. Alterations in the Liver, Gill, Heart, Kidney and muscle of fish exposed to shea butter effluent were semi-quantitatively ranked based on the severity of tissue lesions and comparisons were made with fish in the control groups. Fish of the control groups exhibited functionally normal Liver, Gill, Heart, Kidney and muscle. Histopathology of the organs; Liver, Gill, Heart, Kidney and muscle after 14days exposure revealed; congestion of central vein of varying degrees and distortion of hepatocytes in liver, inflamed and degenerated renal corpuscles in kidney, poor and degenerated gill filaments, distorted, irregular and fragmented muscle fibres coupled with distorted muscle fibres, irregular interfibre spaces and areas of inflammatory changes in the heart.
