Fishpen culture as a new production system in dammed valleys in the mid-Casamance, Senegal

Fishpen culture is a possible means to increase fish production in Casamance, Senegal and to develop aquaculture without negative environmental effects. To study this possibility, a fishpen study was conducted in two dammed valleys, Guidir and Balobar in the area. Wild Sarotherodon melanotheron from 7.7 to 25.4 g and Tilapia guineensis from 7.7 to 35.0 g were stocked at densities ranging from 1.5 to 2.5 individuals/ super(m). Results are summarized in this article.
