COMPOSITION OF THE FISH CATCHES FROM THE LOWER RIVER NIGER AT IDAH, KOGI STATE
Abstract
This study examined the composition of fish catches from the Lower River Niger at Idah, Kogi State. The study is justified by the need to generate reliable, region-specific data on the composition of fish catches from the lower River Niger at Idah. The study was conducted in the lower River Niger, specifically around the Idah region of Kogi State, located in the central part of Nigeria. The total length (cm) and weight (g) were taken by using a graduated meter rule and weighing balance respectively. The most frequently recorded fish species are Oreochromis niloticus (Nile Tilapia), with 4 individuals, followed by multiple species (Chrysichthys nigradigitatus, Alestes baremose, Synodontis batensoda, Aletes macrotepidotus, and Labeo couble. Carias gariepinus (African Catfish) had the highest recorded weight of 408.59 g (28.71%) while Chrysichthys nigradigitatus (Silver Catfish) had the lowest weight of 10 g (0.70%), despite being one of the more frequently recorded species (3 individuals), indicating its smaller size or younger age during capture. It is recommended that assessment of reproductive status, age, and population dynamics should be carried out for better management strategies. Species with higher weights and lengths (Carias gariepinus) can be targeted for aquaculture development.
