    between salmon consumption and consumer population productivity. Bald eagles (Haliaeetus leucocephalus) in southeast Alaska had an increased proportion of active nests and an earlier laying date when salmon carcasses were abundant and available due to strong fall runs and a subsequent early spring thaw of spawning streams (Hansen ). The Atlantic salmon (Salmo salar) is a species of ray-finned fish in the family Salmonidae which is the largest salmon and can grow up to a meter in length. It is found in the northern Atlantic Ocean and in rivers that flow into this ocean. Most populations of this fish species are anadromous, hatching in streams and rivers but moving out to sea as they grow where they mature, after which the.

Washington.   From coastal shores to inland mountains, salmon are part of the fabric of Alaska. Salmon have been harvested by Alaska Natives for thousands of years and remain a critical part of the state’s commercial, recreational and subsistence fisheries. As anadromous fish, salmon spend the first months to years of their lives in freshwater before migrating.

None are listed under the Endangered Species Act (ESA). Review of Salmon Escapement Goals in Southeast Alaska, ; West Coast. The sockeye salmon (Oncorhynchus nerka) are the only salmon to rear in a lake 1 – 2 years before going to sea. The world’s largest wild sockeye salmon runs are found in Bristol Bay, Alaska.
