Abstract

Clarias species purchased from fish mongers from Ado – Ekiti, Ikun Ekiti, Itapaji – Ekiti Nigeria were examined for possible deformities in any part of their body. A total number of 360, 140, and 40 fish samples were from Ado – Ekiti, Ikun – Ekiti, and Itapaji – Ekiti respectively. Deformities of various types were observed only from Ado – Ekiti collection. The deformities observed are malformed mouth, big head, stumpy body, and multiple vertebral deformities. The possible cause (s) of the deformities may be as a result of stress, pollution from human activities or other factors such as poor nutrition, hereditary, diseases, etc. but these causes has not been properly determined
