| The occurrence of ichthyoparasites and their cumulative effects was observed at the inner Nyanza Gulf region of Lake Victoria. Protozoa, Nematoda, Cestoda, Crustacea and Trematoda are mentioned. The parasite fauna and the biocoenology of the hosts were studied and the seasonal variation in infectivity was observed. Infection in the dams was prevalent and was 75% at the peak. Some gill infected specimens were examined between July and February. Infestation rates were higher during the dry season. Males and juveniles dominated the infected samples throughout the study period. The distribution pattern of the hosts was also noted. |
