ABSTRACT

This study investigates the toxicity of Costus afer on the histopathology of the gills of Clarias gariepinus fingerlings. Results indicates a concentration-dependent pattern of mortality, with significant reduction observed over time of exposure. Experimental groups exposed to C. afer exhibited pathological changes in the gills and behavioural abnormalities. Additionally, variations in water quality were observed following the introduction of the extract. The calculated LC₅₀ of C. afer was determine to be 20.5 mg/l, providing crucial insights into the potential ecological impact of this plant extract on aquatic organisms.
