Fish farming is one of the cost-effective means of increasing animal protein production to address the problem of low per caput animal protein consumption experienced in most developing countries.
Professor Osuigwe’s early research works were directed towards providing adequate catfish seed, a major constraint than in fish farming. With the successful development of protocols for African catfish production, Professor Osuigwe’s research interest
shifted to the development of low-cost fish feed through replacement of the expensive fish meal component with locally available materials particularly legumes.
Professor Osuigwe’s research interest also includes cage culture and fish health particularly with the current intensification of fish farming methods in Nigeria.
Professor Osuigwe anchored the development of “fishers assistant programme” in the Lower Niger floodplains to enable fishers to harvest the abundant flood ponds. He was the team leader NDDC Natural Resources Assessment for Imo and Abia States (2003 –2005). He has been involved in aquatic environment surveys.
