2020 Yukon River Salmon Fall Fishery Announcement #11 District 4 and Koyukuk River Drainage Subsistence Fishing Schedule

Districts Affected: Upper Yukon Area


The 2020 fall chum salmon inseason projection is for a run size of less than 300,000 fish, which is the second lowest run size since the year 2000. Mixed stock analysis was applied to the passage estimates to remove summer chum salmon and resulted in an estimate of 78,000 fall chum salmon in the river as of August 9.

The mid-point of the fall chum salmon run at the mainstem sonar operated near Pilot Station typically occurs on August 11. The projected abundance is below the level needed to meet the drainagewide escapement goal of 300,000-600,000 fall chum salmon, tributary escapement goals, and Canadian treaty objectives. Fall chum salmon are typically dominated by age-4 fish; however, the 2016 parent year that produced that age class has shown extremely poor survival in chum salmon runs throughout the state. Consequently, subsistence salmon fishing periods in the District 4 and the Koyukuk River drainage are cancelled until further notice to allow fall chum salmon to reach their spawning areas. The department will continue to assess the run to determine if there are surpluses of chum salmon for further harvest opportunities.
