A recent study conducted by researchers from the Institut National Polytechnique Félix Houphouët-Boingy, the Université Montpellier, and the Université Nangui Abrogoua has found that earthen ponds are more productive than hapa nets in terms of tilapia larvae production. The research, published in Aquaculture Research, involved rearing Nile tilapia broodstock in both systems and found that the ponds produced a higher number of larvae and higher quality larvae compared to the hapas. The best reproductive performance was also recorded in the pond-reared broodstock, with an absolute productivity of 93.1 larvae per female and a relative productivity of 0.3 larvae per gram of female. The study recommends that tilapia farmers should consider using earthen ponds for raising broodstock due to the higher larvae yield and quality.
