The fish fauna changes and the place of clupeids in Lake Kainji,Nigeria

The fish fauna changes and the place of the clupeids was examined. It was found that the conditions in the lake since impoundment have favoured the growth and development of these little sardines. The studies undertaken prior to impoundment and their continuation right from the time of the closure of Kainji Dam in August 1968 has made it possible for these changes to be followed sequentially.
