Abstract

The incidence, intensity and effects of nematode infection in the Nile tilapia, Oreochromis niloticus, in Lake Wamala and their biological characteristics, were investigated. Six hundred and thirty fish were examined using standard techniques and found to harbour nematodes belonging to the genus Contracaecum. The parasites were found concentrated in the pericardial region. The incidence and intensity of infection increased with the length of the host besides and it correlated with the onset of maturity of the host. Factors responsible for the variation in the prevalence of the helminths , intensity of infection and their implications are discussed.
