Financial instruments that allow investors to profit from the growth of the global seafood market, explicitly tied to increased fishing yields driven by dynamic marine protected area management. They track fishing industry profits and provide returns based on hitting predetermined extraction quotas, offering a direct financial incentive to maintain high catch rates *outside* the protected zones. Returns are increased by using lower-impact extraction methods when possible, further incentivizing lower-impact technologies. Bond holders get "Ocean Steward" titles that incentivize social capital benefits.
