Helminth parasites in freshwater fish species from Jebba Lake and Bida Floodplain areas of River Niger, Nigeria

A total of 610 freshwater fish specimens comprising 7 scaly fishes (Sarotherodon,Oreochromis, Tilapia, Marcusenius and Brycinus) and 6 non-scaly catfishes (Clarias, Chrysichthys,Synodontis arid Physailia) belonging to 7 families and 9 genera, from Jebba Lake and Bidafloodplain areas of River Niger, Nigeria, between June 2004 and May 2006, were sampled andexamined parasitologically for helminth parasites. Nine species of 1331 helminth parasitescomprising five nematodes Eustrongylides africanus, Procamallanus laeviconchus, Spironourapetrei, Cucullanus bavlisi and an unidentified species; cestodes Proteocephalus ambloplitis andWenyonia virilis keinjii, and two trematodes Oiplostomum tragenona and Euclinosiomumheterostomum were obtained from 198 infected fishes. The distribution of the helminth parasiteswere 48.4%; 35.6%; 15.1 %; 0.3%; 0.2% and 0.1% respectively in the intestine; pyloric caeca(stomach); muscle; liver and gills, gut and kidney. There was statistically significant difference (P <0.05) between the infection rate and sexes of the fish species. The examined fish population showsthat the female fish species were more infected than the male. Higher infection rate, mean intensityand abundance were found in female than in males and statistically insignificant (P > 0.05).the nonscalycatfish species were more proned to helminth parasites infestation than the scaly fish species;this might be due to morphological features. The study was carried out to provide information on thetypes, check list and problems of helminth parasites affecting the freshwater fish species fromJebba Lake and Bida floodplain areas of River Niger, Nigeria in order to create awareness to fishhandlers and/or culturists and to facilitate monitoring them when and if they occur in aquaculture.
