Preliminary studies in rice-fish culture in a rainfed lowland ecology in Ghana
AbstractMixed farms of rice and fish are yet to receive attention in Ghana, despite lowland rice being grown under inundation in most areas nationwide. In a preliminary study, Nile tilapia (Oreochromis niloticus) was successfully cultured in a rainfed lowland rice farm, although no additional care was provided for fishes. The highest yielding rice variety produced 4.8 t/ha (480 kg/1000 m2) which was commensurate with previous yields at the same location. Parent fish yield of 121 g/fish for a period of 139 days was also commensurate with yield from fish ponds. This excluded yield of fish progeny. With proper management, fish yields would greatly complement that of rice.
