Book Description
Pacific herring in Southeast Alaska and Yakutat are harvested for subsistence, personal use, and commercial purposes. Subsistence products include whole herring and spawn on branches or kelp; commercial fisheries occur for food/bait, sac roe, and spawn on kelp. At times, the Alaska Department of Fish and Game conducts test fisheries for research and cost recovery. Commercial fisheries account for most harvest, which peaked during the reduction fishery in 1929/30 with 78,749 tons. Large-scale reduction fisheries operated during 1890s-1967. A winter bait fishery has generally occurred every year since the turn of the century. The sac roe fishery became the dominant fishery beginning in 1971. A wild spawn-on-kelp fishery occurred between 1963 and 1969, with a closed pound fishery authorized by the Alaska Board of Fisheries beginning in 1990. The management strategy for herring combines a sliding scale harvest rate and minimum biomass threshold to determine allowable harvest levels. Harvest rates may be set between 10% and 20% of forecasted mature biomass when above threshold, except in Sitka Sound where harvest rates may be set between 12% and 20%.

Book Description
Pacific herring in Southeast Alaska and Yakutat are harvested for commercial bait, commercial sac roe, commercial spawn-on-kelp, subsistence spawn-on-branches, subsistence spawn-on-kelp, and personal use fisheries and Alaska Department of Fish and Game test fisheries. Prior to 1967, a reduction fishery accounted for most of the commercial harvest with a historic high of 78,749 tons during the 1929/30 season. A winter bait fishery has generally occurred every year since the turn of the century. The sac roe fisheries became the dominant fishery beginning in 1971. A wild spawn-on-kelp fishery occurred between 1963 and 1969, with a closed pound fishery authorized by the Board of Fisheries beginning in 1990. During the most recent completed season of 2016/17 season, the total regional commercial harvest of herring, including estimates of herring used for commercial spawn on kelp, was 15,457 tons. The sac roe harvest totaled 13,923 tons. The commercial harvest of spawn on kelp product was 70 tons, resulting in an estimated 875 tons of herring caught for supplying pounds. Commercial harvest in the winter bait fishery totaled 527 tons. Test fisheries in the region accounted for approximately 133 tons of herring. No herring fishery occurred in the Yakutat area. The management strategy for herring combines a sliding scale harvest rate and minimum biomass threshold to determine allowable harvest levels. Harvest rates may be set between 10% and 20% of forecasted mature biomass, when above threshold, except in Sitka Sound where harvest rates may be set between 12% and 20%.

Book Description
This report describes the Southeast Alaska/Yakutat salmon troll fishery, management methods, and actions taken by the Alaska Department of Fish and Game during the 2020 Chinook salmon accounting period, which occurred from October 1, 2019, through September 30, 2020. Approximately 1.05 million salmon were harvested in the 2020 Southeast Alaska troll fishery. Of this, 30,000 salmon (3%) were taken by hand troll gear and 1.02 million salmon (97%) by power troll gear. The harvest included 170,000 Chinook (Oncorhynchus tshawytscha), 1,700 sockeye (O. nerka), 751,000 coho (O. kisutch), 44,000 pink (O. gorbuscha), and 79,000 chum (O. keta) salmon landed by 624 power troll and 203 hand troll permit holders during the 2020 calendar year. The Chinook salmon harvest was rank as the 11th lowest and coho salmon harvests as the 18th lowest over the last 61 years since statehood, whereas the chum salmon harvest ranked 28th lowest over the same time period. The preliminary estimated Alaska hatchery contribution of Chinook salmon to the troll fishery, including hatchery terminal harvest, was 7,640 fish (4%). A total of 205,366 coho salmon produced by Alaska hatcheries were harvested by the troll fleet, accounting for 28% of the total troll coho salmon harvest. Chinook salmon escapements for 6 out of 11 Southeast Alaska rivers were within the desired escapement goal ranges, whereas escapements for 7 of the 11 coho salmon indicator systems were within or above the desired escapement goal ranges.

Book Description
This report describes the Southeast Alaska/Yakutat salmon troll fishery, management methods and actions taken by the Alaska Department of Fish and Game from October 1, 2016, through September 30, 2017. Approximately 2.7 million salmon were harvested in the 2017 Southeast Alaska troll fishery. Of this, 120,000 salmon (4%) were taken by hand troll gear and 2.6 million salmon (96%) by power troll gear. The harvest included 130,000 Chinook (Oncorhynchus tshawytscha), 5,400 sockeye (O. nerka), 2.1 million coho (O. kisutch), 54,000 pink (O. gorbuscha), and 403,000 chum (O. keta) salmon landed by 722 power troll and 250 hand troll permit holders during the calendar year. The Chinook salmon harvest ranked as the lowest on record over the last 58 years since statehood, while the coho salmon and chum salmon harvests ranked sixth and ninth over the same time period, respectively. The preliminary estimated Alaska hatchery contribution of Chinook salmon to the troll fishery, including hatchery terminal harvest, was 8,600 fish (7%). A total of 388,000 coho salmon produced by Alaska hatcheries were harvested by the troll fleet, which accounted for 18% of the total troll coho salmon harvest. Chinook salmon escapements for two out of 11 Southeast Alaska rivers were within the desired escapement goal ranges, while coho salmon escapements were generally within or above the desired escapement goal ranges. report describes the Southeast Alaska/Yakutat salmon troll fishery, management methods and actions taken by the Alaska Department of Fish and Game from October 1, 2015, through September 30, 2016. Approximately 1.9 million salmon were harvested in the 2016 Southeast Alaska troll fishery. Of this, 73,000 salmon (4%) were taken by hand troll gear and 1.8 million salmon (96%) by power troll gear. The harvest included 276,000 Chinook (Oncorhynchus tshawytscha), 6,700 sockeye (O. nerka), 1.4 million coho (O. kisutch), 53,000 pink (O. gorbuscha), and 165,000 chum (O. keta) salmon landed by 745 power troll and 273 hand troll permit holders during the calendar year. The Chinook salmon harvest ranked 21st highest over the last 57 years since statehood, while the coho salmon and chum salmon harvest both ranked 19th highest on record. The preliminary estimated Alaska hatchery contribution of Chinook salmon to the troll fishery, including hatchery terminal harvest, was 13,800 fish (5%). A total of 338,000 coho salmon produced by Alaska hatcheries were harvested by the troll fleet, which accounted for 24% of the total troll coho salmon harvest. Chinook salmon escapements for two out of 11 Southeast Alaska rivers were within the desired escapement goal ranges, while coho salmon escapements were generally within or above the desired escapement goal ranges.
