The present study investigated the histopathological and biochemical changes that occur in the ovaries of the freshwater African catfish, Clarias gariepinus (Burchell, 1822), after exposure of CdCl2. Fish were exposed to two different concentrations of CdCl₂, a low dose (10 mg/L), a high dose (20 mg/L) along with control. The present study showed according to biochemical analysis protein and carbohydrate concentration of ovaries decreased in a dose-dependent manner with notable decrease seen at higher cadmium doses. Histopathological analysis revealed damage to ovarian tissue including oocyte degeneration, atresia, and vacuolization that increased with dose of cadmium exposure. The findings suggested that cadmium chloride has deleterious effects on the reproductive function of Clarias gariepinus, possibly affecting the ability of the species to reproduce in contaminated aquatic environments by disrupting the histoarchitecture of ovaries and metabolic equilibrium.
