Freshwater snails are commonly found in aquaria along with tropical fish and vary in different parts of the world. Studies on parasites association with fauna species are paramount to environmental health matters. The study examined the body weight and endo parasites prevalence of freshwater snails in Benue State, Nigeria. A total of 300 freshwater snails were sourced from the river (average of 50 from each) at three locations namely; Makurdi, Kastina-Ala and Ogbadibo (L.G.A) of Benue State. Body weight measurement and parasites isolation procedures was done accordance to standard methods. Data were analyzed using descriptive statistics and students t-test. Schistosomes were the main endo-parasites prevalent in the snails. The rate of parasites infection was high for all the locations. The result also revealed higher mean body weight (0.45kg) in snails from Makurdi. It was observed that snails with higher infection seem to have lower body weight. Result of ANOVA showed significant difference in body weight between snails of Makurdi and Ogbadibo compared to Makurdi and Katsina Ala. The parasite load was higher (34.42%) at Ogbadibo. It was observed also that snails with higher parasite load tend to have lower body weight. This was evident with snails obtained at Katsina Ala and Ogbadibo respectively. Adequate attention should be given towards control of the endo parasites especially for consumption.
