Alaska’s pollock fisheries have received another sustainability certification.

Global Trust, a committee of independent auditors, spent nine months reviewing the Bering Sea and Gulf of Alaska pollock fisheries to figure out whether they were being responsibly managed. They determined that the fisheries met United Nations standards, making pollock the fourth Alaskan fishery certified by the group. Halibut, salmon, and black cod all received Global Trust certification earlier this year.

Sustainability certifications are valuable marketing tools for the fishing industry. The pollock fishery is already certified by the Marine Stewardship Council, which allows products like fillets and fish sticks to come with eco-labels that let consumers know that the fishery is managed with an eye toward the future. That’s part of why the Alaska Seafood Marketing Institute (ASMI) commissioned the review.

“This whole certification program that we are embarking on is at the request of customers and industry. Now, the customers – meaning the major retailers and restaurants out there – want to know that they’re sourcing sustainable seafood products,” says Tyson Fick, who works for ASMI. So, our certification program satisfies that corporate responsibility.”

Global Trust is also in the process of assessing Alaska’s crab fisheries. Their review is expected to be complete within the next year.
