The Marine Stewardship Council’s (MSC) new version of its fisheries standard has been given the green light by its board of trustees.

After a four-year review -- involving more than 1,000 stakeholders and significant scientific research -- the board of trustees unanimously approved the new fisheries standard on June 24, hailing it "a major achievement".

Currently, 539 fisheries are certified to the MSC standard, representing 16 percent of wild marine catch.
