Book Description
In Southeast Alaska, chum salmon (Oncorhynchus keta) spawn in more than 1,200 streams. The Alaska Department of Fish and Game maintains a standardized survey program to index spawning chum salmon abundance at 87 summer-run and seven fall-run streams. Lower-bound sustainable escapement goals are established for summer-run stocks comprising aggregates of index streams over three broad subregions (Southern Southeast, Northern Southeast Inside, and Northern Southeast Outside) and sustainable escapement goal ranges are established for five fall-run stocks that support directed fisheries (Cholmondeley Sound, Port Camden, Security Bay, Excursion River, and Chilkat River). We reviewed chum salmon escapement goals and recommend that summer-run chum salmon goals continue to be based on the 25th percentiles of historical escapement index counts, primarily due to the uncertainty regarding harvest rates. We recommend reducing the Northern Southeast Inside Subregion lower-bound sustainable escapement goal from 119,000 to 107,000 fish. For fall-run chum salmon stocks, except for the Chilkat River, we also recommend continuing to base escapement goals on the 25th and 75th percentiles of historical escapement index counts, and recommend no changes at this time. Summer-run chum salmon escapement goals were met in four of the past five years in the Southern Southeast and Northern Southeast Outside subregions, and in three of the past five years in the Northern Southeast Inside Subregion. Escapement goals were met for the five fall-run stocks 84% of the time over the past 5 years. The annual common property harvest of chum salmon in Southeast Alaska averaged 6.9 million fish per year since 2007; hatchery-produced fish accounted for an average 85% of that harvest. No Southeast Alaska stocks of chum salmon currently meet the criteria for stocks of concern as defined by the State of Alaska's Policy for Management of Sustainable Salmon Fisheries (5 AAC 39.222).
