Demand for sustainably certified wild-caught fish and crustaceans is increasingly shaping global seafood markets. Retailers such as Walmart in the United States, Sainsbury’s in the United Kingdom, and Carrefour in France, and processors such as Canadian-based High Liner Foods, have promised to source all fresh, frozen, farmed, and wild seafood from sustainable sources by 2015. Credible arbiters of certifications, such as the Marine Stewardship Council (MSC), require detailed environmental and traceability standards. Although these standards have been met in many commercial fisheries throughout the developed world, developing country fisheries (DCFs) represent only 7% of ~220 total MSC-certified fisheries. With the United Nations Food and Agriculture Organization reporting that developing countries account for ~50% of seafood entering international trade, this presents a fundamental challenge for marketers of sustainable seafood.
