The present work is now concentrated mainly on the Tilapia fishery. As a result of past experience it is easier to direct efforts in a way likely to give useful results. Work on the Tilapia is now beyond the purely exploratory stage and these fishing experiments are being carried but in areas which are known to contain large numbers of Tilapia. Nets of different mesh size are being used in order to catch all stages of these fish. These nets are being fished at the surface and at the bottom, close to the shore and further out. The data collected should provide more precise information regarding the periodic migration, both vertical and horizontal, of these fish, a better understanding of their life history and breeding habits, and indicate' the potential possibilities of this fishery. These data should explain the variation in numbers of fish caught by Africans during different months of the year; they should also make it possible to determine more exactly the best type of net for use in this particular fishery.
