Helminth parasites of fishes from two inland lakes in Egypt

Abstract

Results of helminthological examination of 1243 fishes, caught from two inland lakes, with unique and contrasting hydrobiological features at Fayoum Governate in Egypt, are presented.

General incidence of trematodes, cestodes, nematodes and acanthocephalans in fishes from the two lakes are compared. Eleven genera of digentic trematodes are reported for the first time in certain fishes of the two lakes. The incidence of single, simultaneous double or multiple infections with digentic trematodes in fishes of the two lakes are compared. The respective relationships of digentic trematode fauna of fishes from the two lakes with those from the River Nile and the Mediterranean Sea are suggested.
