The `Seafood Gap’ in the Food-Water Nexus Literature—Issues Surrounding Freshwater Use in Seafood Production Chains

This study (1) reviews freshwater use concepts as they relate to seafood production, (2) provides three cases to highlight the particular water use concerns for aquaculture and (3) outlines future directions to integrate seafood into the broader food-water nexus discussion. By revisiting water use concepts through a focus on seafood production systems, we highlight the key water use processes that should be considered for seafood production and offer a fresh perspective on the analysis of freshwater use in food systems more broadly. Evaluating the primary freshwater uses in seafood production, this study provides guidance on the necessary considerations for comparative analyses which include seafood and offer a fresh perspective on the analysis of freshwater use in food systems more broadly.
