Freshwater aquaculture dominates global aquaculture production, but its importance is often overlooked in global food-policy agenda and research. In a new study published in Nature, Dave Little and Richard Newton at the Institute of Aquaculture, University of Stirling and external colleagues led by Dr Wenbo Zhang of Shanghai Ocean University argue that recent research underestimates the production potential for freshwater aquaculture and inflates the importance of mariculture, or saltwater aquaculture. In this podcast, Professor David Little talks with Dr Wenbo Zhang about the study and the paper that prompted it.
