Fish are a major source of protein to humans and one of the constraints to improved fish production in Nigeria are parasites/parasitic diseases. A study to evaluate the parasites of African catfish (Clarias gariepinus Burchell, 1822) cultured in selected homestead ponds in Rivers State, Nigeria was conducted from January to June, 2023. One hundred and twenty catfish were randomly selected from two homestead ponds (sixty fish per pond) and categorized (sex, weight and length); each fish was analyzed for parasites (ecto and endo) using standard parasitological techniques. Descriptive analyses (mean and percentages) were used to represent data obtained and chi-square test was used to determine the level of significance with a P0.05).According to weight, parasite prevalence values of 4 (16.0%), 4 (17.4%), 8 (28.6%), 8 (30.8%) and 6 (33.3%) were recorded for 140 – 160g, 161 – 180g, 181 – 200g, 201 – 220g and 221 – 240g respectively while according to length, parasite prevalence values of 8 (21.1%), 10 (24.4%), 7 (26.9%) and 5 (33.3%) were recorded for 20 – 22cm, 23 – 25cm, 26 – 28cm and 29 – 31cm respectively (P>0.05). Proper management practices should be adhered to in aquaculture to increase yield and reduce the detrimental effects of fish parasites.
