Abstract: There is expansion of the fishery sector in Cameroon but there is dearth of information on the distribution, magnitude and risks of freshwater fish diseases in the country. This study wascarried out to determine the prevalence and associated risk factors of ectoparasites on cultured fishes in West Cameroon.The external surfaces of 2254 randomly selected fishes (692 Clarias gariepinus, 969 Oreochromis nilotichus, 593 Cyprinus carpio) were examined using standard parasitological procedures. The results showed that 34.9% of sampled fishes were infected with ectoparasites including Crustaceans (12.0%), Monogeneans (15.8%) and Protozoans (15.8%). The prevalence was higher (p<0.05) in Cyprinus carpio compared to Clarias gariepinus and Oreochromis niloticusspecies. Female and large fishes were most infected (p<0.05) compared to male and small fishes. The study revealed mixed and high prevalence of ectoparasite infections of cultured fish species in West region of Cameroon and fish species, sex and size were the major risk factors.
