Maintaining and enhancing the ecological health of fisheries is critical both to maintaining the health of fish stocks and to the companies that rely on fish and fish-related products (fishing companies, seafood processors). Conservation standards such as those from the Marine Stewardship Council play an important role in protecting and enhancing the world's major fisheries. Investors have a direct interest both because of their direct investments in these companies and in sectors that use fish-derived products, including retailers, restaurants and bars, and animal feed companies.
