Abstract
The Waange-Sewa basin with its extensive floodplains forms the major part of the Sherbro estuary. It is identified as one of the foremost areas for agriculture and fisheries in the southern part of Sierra Leone. Preliminary analysis on basic physico-chemistry and fish fauna of the rivers and lakes within the Waange-Sewa basin were made for the dry season and rainy season of 1983. Physico-chemical variables were used to estimate potential fish production for its river, floodplains, and lakes.
