Representatives from the Alaska Fisheries Development Foundation visited Unalaska last week as part of its push to expand the state's mariculture industry.

Gov. Bill Walker created the Alaska Mariculture Task Force in 2016. Since then, the organization has been focused on developing the state's mariculture industry to meet its long-term goal of $100 million by 2038.
