ITQs increase fishery efficiency, but have been criticized for redistributing income away from small communities and increasing concentration in production. We empirically examine these effects in the 1995 adoption of ITQs in the Alaskan halibut and sablefish fisheries. Fishing ports generally do not lose harvesting or processing revenue, but both processors and vessel owners consolidate, and fewer fish are delivered to the home port of the fisher. Small coastal cities see a reduced number of vessel owners and may experience overall population declines. Written and oral testimony suggests pre-adoption opposition may be increased when community residents foresee these changes.
