My research in fisheries focuses on inland capture and aquaculture-based fisheries, community-based fisheries management, indigenous knowledge in fisher communities, fisheries co-management, trophic evaluation in fish communities of reservoirs, streams and estuaries, and conservation of aquatic biodiversity. I teach aquatic ecology, environmental conservation and management, fish population dynamics and stock assessment, management of capture fisheries and aquaculture-based fisheries, at undergraduate and postgraduate levels. So far, I have trained thirty four postgraduate students (07 Ph.D. degrees, 13 M.Phil. degrees and 14 M.Sc. degrees). At present, nine postgraduate students carry out research under my supervision. I have been awarded a Doctor of Science (D.Sc.), by the Bangor University in North Wales, UK in July 2010, for my life-long scientific contribution to fisheries biology and development of inland fisheries in Sri Lanka. I was also the winner of the Excellence Award of the Committee of Vice Chancellors and Directors (CVCD) in 2008 and General Research Committee Award of Sri Lanka Association for Advancement of Science in 2009, for my lifetime achievement as the most outstanding scientist Sri Lanka in biological sciences.
