Résumé

The relative composition of the major fish families in Lake Kainji between 1974 and 1975 is analysed and compared with pre- and post-impoundment data collected by previous workers. Trends in the fishery are assessed, and it is concluded that the cichlids, particularly Sarotherodon (= Tilapia) galilaeus Artedi, are becoming the dominant commercially valuable fish. No evidence was found of a significant recovery in the formerly abundant citharinids. The value of the sampling technique is discussed and criticised in relation to under-assessment of certain species, notably S. galilaeus. The Schilbeidae were found to be one of the most numerous families in the lake but are commercially under-exploited.
