2018 Yukon River Fall Salmon Fishery News Release 64 Fall Update # 10, Yukon Area Salmon Fishery

The peak of the fourth pulse is expected to be near the U.S./Canada border around September 26. The fifth pulse, which was the largest of the season, is expected to be near Fort Yukon around September 25, and the U.S./Canada border around October 5. The smaller sixth pulse contained a majority of Tanana River bound stocks.

The coho salmon were three days later than average at the mainstem Yukon River sonar site at Pilot Station. The inseason total run size of coho salmon (based on passage at the mainstem sonar near Pilot Station plus the harvest downstream of the sonar) is estimated to be 237,000 fish, which is above the historical median of 209,000 fish. Coho salmon are expected to be within the Tanana River typically peaking around mid to late October.

Fall Assessment Projects

Lower Yukon River Cooperative Fall Drift Test Fishing / ADF&G, YDFDA

This project concluded operations on September 10, 2018. The fall chum salmon cumulative CPUE for the project was 2,961.66, which was above the historical median of 1,520.50 for this date. The coho salmon cumulative CPUE was 381.96, which is below the historical median of 443.37 for this date.

Mountain Village Drift Test Fishing / Asacarsarmiut Traditional Council

This project concluded operations on September 12, 2018. The fall chum salmon cumulative CPUE for the project was 3,018.41, which is above the historical median of 2,051.51 for this date. The coho salmon cumulative CPUE was 679.52, which is below the historical median of 1,121.91 for this date.

Sonar Project near Pilot Station / ADF&G

The mainstem sonar near Pilot Station completed operations for 2018 season on September 7. The cumulative passage estimate was 927,000 fall chum salmon, which is above the median passage of approximately 707,000 fish for that date. Fall chum salmon run timing was seven days later than average at this project. The cumulative passage estimate for coho salmon was 137,000 coho salmon which is below the median of 160,000 for that date. Coho salmon run timing was four days later than average at this project.

Chandalar River Sonar / USFWS

The cumulative passage attributed to fall chum salmon through September 23, is 111,231 fish which is well below the median of 199,000 fish for that date. The lower end of the Biological Escapement Goal range from 74,000 to 152,000 was achieved on September 18.

Sonar Project near Eagle / ADF&G, DFO

The mainstem sonar operated near Eagle transitioned from Chinook to fall chum salmon beginning August 21. The cumulative fall chum salmon passage estimate through September 23 was 49,431, which is below the median passage of approximately 98,000 fish for this date. The low passage at the beginning of the run was not unexpected given that the fall chum salmon run was late entering the lower river, in the recent week the daily passage has significantly increased as it nears the peak passage days.

Upper Porcupine Sonar / Yukon Territory Canada / DFO

This project has had difficulties with high water most of the season. One bank operations began on August 27 while the second bank became operational on September 6. The cumulative passage attributed to fall chum salmon based on partial operations is 7,877 fish which is below the average of 26,000 through September 23. Run timing is expected to be late based on other downstream assessment projects.

Fishing Branch River Weir/Sonar / Yukon Territory Canada / DFO

Water levels began higher than average and have delayed weir deployment. Sonar operations began on September 3 and the weir is still being assembled as water levels permit. The estimated passage as of September 22 was 1,574 fall chum salmon which is well below the median of 15,539 for this date. Counts prior to September 15 (the day the river was fully ensonified) are considered minimum estimates. Similarly, run timing is expected to be late based on other downstream assessment projects.

Chum Salmon Stock Identification

Genetic mixed stock analysis of chum salmon for the entire fall season, from July 19-September 7, that passed the mainstem Yukon River sonar contained approximately 17% summer chum and 83% fall chum salmon. The fall component only entering after July 19, represented 28% BorderUS (Chandalar/Sheenjek), 30% Canadian, and 42% Tanana Fall stocks.

Fall Season Management Strategy:

Subsistence fishermen may use 7.5 inch or smaller mesh size gillnets and fish wheels in all areas of the Yukon River. Because of the Chinook salmon restrictions put in place in the Yukon Area this season, the department increased the opportunity to harvest fall chum salmon for subsistence use to seven days per week, 24 hours per day in all of Districts 4 and 5.  

In recent years, the abundance of fall chum salmon in the upper Porcupine River has been low when compared to other stocks in the Yukon River drainage. Fall chum salmon escapements into the Canadian Fishing Branch River, a tributary of the Porcupine River, have fallen short of meeting the escapement objective agreed upon by U.S. and Canadian representatives despite other Yukon River stocks meeting or exceeding their escapement goals or objectives. Like the action taken in previous years, to improve fall chum escapement to the spawning grounds in Canada, a subsistence salmon fishing schedule in the Alaska portion of the mainstem Porcupine River is being implemented. Managers will closely monitor inseason information at the mainstem Porcupine River sonar and the Fishing Branch River escapement monitoring projects to determine future management actions as appropriate.
