Parasitic infestations of 120 specimens of three freshwater fish species, comprising of Lates niloticus (44), Clarias anguillaris (40) and Oreochromis niloticus (36) sold at the Medina Coura market in Mali, were investigated. The fresh fish samples were taken during two seasons (cold and hot) in four fish production areas (Niger Central Delta in Mopti, Selingue, Manantali, Markala) and from the Medina Coura market. In each area, the samples were taken at three points (capture, landing and sale), using standard methods and procedures. A dissection was performed on each fish sample and the conditions of the skin, flesh, gills and abdominal cavity were observed for the detection of infestations. Three species of parasites were detected, namely, Salmincola edwardsii (crustacea) at the gills, and Philonema sp. and Raphidascaris sp. (Nematodes) in the abdominal cavity. An overall prevalence of 10% (12/120) parasitic infestation was observed. Prevalence was lower during the cold season, (5.2% of the fish) than in the hot season (14.5%). The highest prevalence of infestation was observed in Oreochromis niloticus (Tilapia) at 16.7% followed by Lates niloticus (Nile Perch) (9.1%) and Clarias anguillaris (Catfish) (5.0%). Research finding showed that infection prevalence and diversity of parasites were relatively low.
