Yes, they can. Friend of the Sea is the only international programme that can certify products from both fisheries and aquaculture with the same trademark.
Friend of the Sea believes consumers want only a sustainability ecolabel for seafood. Moreover, aquaculture and fisheries are strongly connected because of the potential reciprocal impacts and because fish feed mostly originates from wild-caught fish stocks. Therefore, Friend of the Sea standard includes requirements for sustainable fishmeal, fish oil and fish feed production.
