KETCHIKAN (KDN) — The commercial troll fishing fleet has a 2022 preseason harvest allocation for king salmon that’s higher than it was in 2021, according to the Alaska Department of Fish and Game. 
The troll fleet’s 2022 preseason allocation, which is determined through a U.S.-Canada Pacific Salmon Treaty process, is 193,200 king salmon. That’s 44,700 kings above the preseason limit in 2021.
The commercial troll allocation is part of the all-gear allowable catch limit of 261,300 “treaty” king salmon that’s been set for the Southeast Alaska/Yakutat area. Treaty king salmon are defined as king salmon that were not produced in Alaska hatcheries.
The process that determines the all-gear allocation of king salmon for Southeast Alaska and Yakutat areas is based on the estimated catch-per-unit-effort that occured during the winter power troll fishery in District 113 (which includes the outside waters of Baranof, Kruzof and Chichagof islands) during statistical weeks 41–48 (Oct. 11 through Nov. 27), according to Fish and Game.
“The CPUE metric is translated into a seven-tiered catch ceiling table, with each tier representing a range of CPUEs, the associated Abundance Index values, and the applicable harvest ceiling,” states the department’s announcement.
After the original all-gear harvest number was determined, it was reduced by 2% to “serve as a buffer to avoid exceeding the all-gear limit and payback provisions within the treaty,” according to Fish and Game. 
The winter troll fishery is underway, having started in October. 
“The winter fishery is generally managed to not exceed the guideline harvest level of 45,000 treaty (king) salmon for the season,” according to the department announcement. “However, in 2022, under provisions of the Unuk River Chinook Salmon Action Plan, the winter troll fishery will close March 15.”
The upcoming spring commerical troll fisheries for king salmon don’t have a specific harvest limit, but are managed to focus on Alaska hatchery-produced kings while limiting the catch of treaty king salmon, according to the department.
“Non-Alaska hatchery fish are counted towards the annual treaty harvest limit of (king) salmon while most of the Alaska hatchery fish are not,” stated the department announcement. “Since spring fisheries will be in progress through June 30, preliminary harvest estimates for treaty (king) salmon in the spring fisheries will not be determined until late June.
The allocation for the summer troll fishery harvest allocation is calculated by subtracting the number of treaty king salmon harvested during the winter and spring troll fisheries from the annual troll treaty allocation, according to Fish and Game.
 The summer fishery will be managed to harvest 70% of the remaining troll allocation in the first summer opening for king salmon in July, with the remainder available for harvest in a second opening, which usually occurs in August.
