Selecting the best tilapia strain to maximize productivity
This project at the WorldFish Centre evaluates the relative growth performance of Nile tilapia strains that are currently cultured in the Philippines and compares them with a strain that has been undergoing 13 generations of selection – five generations in the Philippines and 8 generations in Malaysia. Tilapia, principally Nile tilapia (Oreochromis niloticus) is the second most important farmed aquaculture species in the Philippines, after milk fish. The Nile tilapia was imported into the Philippines in the early 1970s but after some initial success and popularity became inbred and yields declined. A ten year multi-national effort for genetic improvement led to the development of the hugely successful GIFT strain (Genetically Improved Farmed Tilapia). The ultimate aim of the study is to identify superior strains of Nile tilapia for aquaculture, when at least four strains will be assessed.
