REPRODUCTIVE PERFORMANCE OF TILAPIA OREOCHROMIS NILOTICUS (LINNAEUS, 1758) IN HAPAS INSTALLED IN PONDS AT THE LAYO EXPERIMENTAL STATION (COTE DIVOIRE)

The limited availability of high-quality fry is a major obstacle to the development of fish farming in Cote dIvoire. This study aimed to assess the reproductive performance of Oreochromis niloticus reared in hapas installed in earthen ponds. Two hapas, each measuring 7,5 m2 and stocked with 42 broodstock (sex ratio of one male to two females), were monitored for six weeks. The broodstock were fed the commercial floating feedcontaining 32 per cent crude protein. The physico-chemical parameters of the water, the zootechnical performance of the broodstock and their reproductive performance were assessed.
