AFRICAN fish farmers are benefiting from improved livelihoods and a better food security status, thanks to the introduction of two strains of improved Nile tilapia in Egypt and Ghana. This follows 10 years of breeding research, culminating in the introduction of the Abbasa strain of the Nile tilapia （Oreochroml：s nlToticus） in Egypt. The species is indigenous to much of Africa. It grows 28 percent faster than most of the common varieties in Egypt, such as the Kafr El Shaikh strain. The second new tilapia Akosombo strain,
