Over-fishing and pollution are a just few of the growing threats to the world’s marine ecosystems. The Marine Stewardship Council (MSC) is an independent, global, non-profit organization whose role is to recognize, via a certification program, well-managed fisheries and to harness consumer preference for seafood products bearing the MSC label of approval.

The Marine Aquarium Council (MAC) is an international, not-for-profit organization that brings marine aquarium animal collectors, exporters, importers and retailers together with aquarium keepers, public aquariums, conservation organizations and government agencies. MAC's mission is to conserve coral reefs and other marine ecosystems by creating standards and certification for those engaged in the collection and care of ornamental marine life from reef to aquarium.

This site offers extensive information about the Marine Aquarium Trade, MAC's certification and standards, as well as information for and about the aquarium industry, aquarium keepers, public aquariums, conservation efforts and certifiers.
