Commercial fishing and seafood processing together account for about three-quarters of the Peninsula’s maritime economy. The maritime sector also includes barge line operators, oil and gas vessel support, the Alaska Sealife Center researchers and staff, AVTEC maritime instructors and staff, sportfish guides and whale watch charters, marine biologists, engineers, and surveyors, fishing crews and gear retailers, fish wholesalers, local government port and harbor workers, state and federal fishery scientists and technicians, and more. Maritime work remains a top sector in the Kenai Peninsula economy.
