Monogenea is a parasite of marine and freshwater fishes. They are  host and organ specific and prefer to colonize the skin and fins while some species prefer to colonize the gills of marine and freshwater fishes. The adult stage of Monogenea are more dangerous to fish health depending on factors such as modes of attachment, size and weight of host. High prevalence of monogeanean parasites may lead to poor growth performance in catfish due to localized hyperplasia, disturbance of osmoregulation and mortality of the fish host. The aim of this study was to determine the proximate analysis of monogenea parasites and to compare the proximate analysis of monogenean infected catfish with the proximate analysis of uninfected catfish. The major constituents of fish were: water, protein, lipid and carbohydrates. Proximate composition has been reported to be a good pointer to physiological need for routine analysis of fisheries. Result of this study shows that the moisture content of the uninfected fish was 0.25% lower than the moisture content of the infected fish while the lipid, ash , fibre, protein and carbohydrate contents of the uninfected catfish were higher,( lipid: 0.15%, ash: 0.55% , fibre : 1.61% , protein: 2.72% and carbohydrate: 2.83%) than those of the infected catfish. It is therefore suggested that since Monogeneans are host specific on fish and do not have intermediate hosts, their presence on catfish sold in the market should not pose any dietary concern.
