Is fish a fish - adding fish to the global food sustainability transformation

The Perspective on food sustainability (T. Garnett, 16 September, 353/6305) gives valuable insights related to links between dietary choices, environmental impacts and health. Substituting meat with fish could, as stated, only result in a transfer of impacts. If, however, fish is caught sustainably, respecting biological limits and using smart fishing methods, capture fisheries can produce low-impact food without requiring land, pesticides, fertilizers or irrigation. This is unique and fishery is the only large-scale food production system based on a wild resource. While many wild fish stocks are fully or over-exploited, global landings could potentially increase by up to 20% if stocks were properly managed .
