Abstract

This study was carried out to detect prevalence of external parasites affecting marine water fishes. Two hundred and twenty-four tilapia and mullet (Mugil cephalus and Tilapia zillii) fishes were collected from AinZiana lagoon, during the period from October 2009 to December 2010. The results showed that the overall prevalence of the ectoprotozoan parasites was 22.3%, prevalence rate in Tilapia zillii was 15.8%, while in M. cephalus was 29.8%.The isolated ectoparasites among examined fishes were Myxobolus sp., Ichthyophthirius multifiliis, Chilodonella sp., Trichodina sp., Tetrahymena sp. And Ichthyobodo necator at prevalence rates 13.80%, 6.5%, 4.5%, 1.3% and 0.9% respectively. It was noted that there are sixteen (84.21%) of T. zillii, and twenty one (67.74%) of M. Cephalus had single infections of ectoprotozoan parasite, and three (15.79%) of T. zillii and ten (32.26%) of M.

Cephalous had mixed infections.
