La pisciculture de Tilapia nilotica (= Sarotherodon niloticus) dans les eaux continentales de Côte d'Ivoire

Abstract

The fishculture of Tilapia niloiica (Sarotherodon niloticus) in freshwater of Ivory Coast. In Ivory Coast, the freshwater fishculture in rural areas is mainly on a small scale. This type of breeding in ponds (2 to 4 ares) yields on an average 3 metric tons of fish/ha/year and represents only an activity with self-consumption of products. The yield in intensive pond fishculture Tilapia nilotica is on an average 6 to 7 metric tons/ha/year but yields bigger than 10 metric tons/ha/year are not uncommon. The intensive fishculture in floating cages, requiring a minor investment but a more improved formation than in fischculture, yields on an average about 30 to 40 kg/m3/year. However the effective development of this activity rests on the resolution of problems like the sufficient fry production, the feeding and the commercialization.
