In January 2018, an interdivisional team, including staff from the Division of Commercial Fisheries and the Division of Sport Fish, was formed to review Pacific salmon Oncorhynchus sp. escapement goals in the Alaska Peninsula and Aleutian Islands Management areas (Area M). This review was based on the Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222) and the Policy for Statewide Salmon Escapement Goals (5 AAC 39.223). Of the 23 existing Area M salmon escapement goals evaluated, the team recommended revising 6 goals, discontinuing 1 goal, and leaving the remaining 16 goals unchanged. After a comprehensive review of the available data, the team recommended that no changes in the current sustainable escapement goals (SEGs) were warranted for 10 sockeye salmon O. nerka systems that include runs to Orzinski, Bear (early and late run), and Thin Point lakes; Mortensens, and Christianson lagoons; and the Cinder, Meshik, Sandy, and Ilnik rivers. No change was recommended for the sockeye salmon biological escapement goal (BEG) at Nelson River. In addition, the team recommended no changes to two of the current aggregate district SEGs for chum salmon O. keta in the North Peninsula, and two coho salmon O. kisutch goals at Nelson and Ilnik rivers. The team did recommend revision of six goals (Nelson River Chinook salmon O. tshawytscha BEG 2,400 to 5,000; McLees Lake sockeye salmon Lower Bound-SEG greater than 10,000; North Creek sockeye salmon SEG 7,500 to 10,000; Southeastern District aggregate chum salmon SEG 62,500 to 151,800; South Central District aggregate chum salmon SEG 68,900 to 99,200; Southwestern District aggregate chum salmon SEG 86,900 to 159,900). The chum salmon aggregate goal reviews incorporated a reduction to the number of index streams, which accounts for the apparent large changes in these goals. The Swanson Lagoon sockeye salmon escapement goal is recommended to be discontinued.
