The action comes after Alaska Wildlife Troopers charged Fields and members of his family with multiple criminal charges involving alleged illegal salmon setnet permit transfers.
Fields believes he's innocent of the charges, and had intended to remain on the ASMI board through the end of his term in July.
He occupied a harvester seat on the seven-member ASMI board, which is controlled by representatives of seafood processing companies.
ASMI describes itself as "a public-private partnership between the state of Alaska and the Alaska seafood industry established to foster economic development of a renewable natural resource."
