The family Cichildae was the most abundant making up 52.1% of the total fish catch. The Clariidae were next in abundance, contributing 20.5% of the total fish abundance. While the Mormyridae were the least abundant making up 3.4% of the total fish catch. Fish composition and abundance was generally poor. However, abundance was significantly higher (p<0.05) in the rainy season months than in the dry season months.
