A preliminary survey of the pre-impoundment population of the fish in lower river Elemi, prior to the establishment of the Ekiti State University (EKSU) power plant was carried out during the rainy season, from June to August, 2015. The stretch of this river is sparsely inhabited by three species of fish. A total of 523 fish were caught during the study from three locations (proposal Site A, B and downstream). This includes tilapia, Oreochromisniloticus (13.58%); the snakehead fish; Parachannaobscura (16.83%) and the catfish, Clariasgariepinus (69.98%), all belonging to the families Cichlidae, Channidae and Claridae respectively. Clariasgariepinus was the dominant fish species. The result of this survey showed that the river has low fish species composition and abundance. There was no serious fishing activity going on, on this river, except for occasional sport fishing by the nearby residents. Scarcity of many different fish species in this river may warrant introduction of relevant fish species to the proposed man-made lake in order to obtain maximum benefit from the reservoir. There is also need to evolve strategies for proper management of the proposed power plant for maximal utilization for power generation and optimum fish production.
