  • From:
    Ca Mau Province of S. Vietnam and other areas of SE Asia
    Method:
    Farmed Extensive Mixed Shrimp and Mangrove Forestry (Silvofishery) Using Selva Shrimp® Criteria

Shrimp is the world’s most valuable seafood and a top choice of North American consumers. Almost half of the shrimp consumed worldwide is farmed, with the majority coming from Asia and Latin America.

Large areas of tropical coastal mangrove forests have been destroyed to build shrimp farms. These are an important habitat for a diverse community of fish, invertebrates, plants and birds. This loss has devastating impacts on local communities and the artisanal fisheries and foraged foods that these people rely on.

Environmental impacts vary from farm to farm and country to country. The supply chain is complex, consisting of approximately 400,000 farmed shrimp producers worldwide, numerous independent processing plants, multiple distributors that import the product and thousands of large retailers and restaurant chains. This makes it difficult for consumers to know the origin of their shrimp and how it was farmed.

In areas of Southern Vietnam and Southeast Asia, some producers are using a mixed shrimp-mangrove system (or silvofishery) that integrates low input brackish water aquaculture with mangrove forestry. These small farms typically do not require supplemental feed or fertilization; while yields are low, the harvest of mature mangroves is a central component of this system. Producers operating silvofishery farms receive a “Best Choice” ranking.

Consumers should “Avoid” imported farmed shrimp unless they can be certain that the shrimp is from a silvofishery operation or a farm in Thailand that use fully recirculating systems, which have “Some Concerns.” U.S. shrimp farms are subject to more stringent environmental laws, resulting in these farms having  “Some Concerns.”
