Abstract

A total number of 1600 cultured freshwater fish species; Oreochromis niloticus (O. niloticus), Clarias garepinus (C. garepinus), Ceprinus carpio (common carp) and Mugil cephalus, 100 of each fish species per season with different weights and sizes, were examined for the presence of common ciliated protozoal diseases affecting the cultured freshwater fish;which revealed the presence of (Trichodina, Chilidonella, Ichthyophthirius multifillis, Apizoma, Epistylis),in relation to their seasonal incidence. The clinical signs and postmortem lesions of diseased fish were recorded. Some heamatological and serum biochemical parameters of diseased fish were reported. The histopathological alterations in skin,gills and fins of naturally diseased fish with ectociliates were also reported.
