Clinostomum tilapiae infestation in cultured Oreochromis niloticus in fish farms within Oyo State, Nigeria is highly significant and the prevalence is normally distributed. The abundance and intensity of the parasite on the skin and within viscera of cultured O. niloticus was closely correlated while intensity was independent of prevalence at 0.05 significance level. C. tilapiae hitherto associated with wild fish species is now well recognized in cultural systems and may pose both economic and public health risks in these areas.
