Abstract

Examination of the fishes revealed the presence of five types of metacercariae infesting six species of fishes namely Tilapia nilotica, T. galilae, Clarias lazera, Bagrus bayad, Mormyrus kannume and Schilbe mystus. The metacercariae are: metacer caria vivax, metacercaria of Haplorchis pumilio, clinstomatid metacercaria, cynodiplostomatid metacercaria and diplostomulum metacercaria.
The incidence, distribution, and seasonal variation of the meta cercariae in different regions of the fish examined were studied.
