Abstract
This study was conducted to evaluate the prevalence of gastrointestinal helminthes and fishing practices of Clarias gariepinus in River Rima, Sokoto. Samples were collected and examined weekly for 10 weeks (August to October, 2015) at Kwalkawalawa landing site along River Rima, Sokoto. Results indicates that 8.33% were infected with 2 Nematode (Procamallanus laeviconchus and Paracamallanus cyathopharynx), 1 Cestode (Monobothrium wageneri) and 1 Acanthocephalan (Neochinorhlynchus rutilli). Nematode had highest prevalence with 54.5%, while Acanthocephalan has the lowest prevalence of 9.1%. It was also observed that stomach had highest prevalence of parasitic infection of 63.6%, followed by intestine with 36.4%. The survey of fishing practices also revealed that despite the awareness of fish depletion among the fishermen, only 93% of the respondents were aware of its consequences. For the regularity of fishing 93.3% of the fishermen fish for more than 5 days in a week. On the size of fish caught 100% of the respondent have choice for the size of fish but 30% of the respondent caught fingerlings, 36.7% caught juvenile while 33.3% of the fishermen caught adult fish. On the species of fish caught, 96.7% of the respondent had choice for specific species despite that the genus Clarias gariepinus being mostly caught (100%). Fishing gear used varied among the fishermen, in which 20% used net, 16.7% used hook, while 63.3% used any fishing gear available to them. It was also observed that the Clarias gariepinus was over-exploited at River Rima which may lead to its depletion.
