2017 Yukon River Fall Salmon Fishery News Release # 10 Fall Update # 1, Yukon Area Salmon Fishery

Districts Affected: Yukon Area

Fall Season Assessment

The 2017 fall chum salmon preseason projection is for a run size greater than 1.1 million fish.  This level of abundance should be sufficient to provide for escapement, an average subsistence harvest, and a surplus available for commercial and personal use purposes. The estimated fall chum salmon run size (based on the mainstem sonar near Pilot Station and the downstream harvest) through July 23 is estimated to be 299,000 fish, which is above the historical median of 72,000 fish for that date. The first pulse of fall chum salmon entered the Yukon River on July 17 and is expected to be near Kaltag on July 28, Galena around July 31, and Tanana/Huslia around August 5, Rampart around August 7 and the Canadian border around August 21.

The coho salmon outlook is for an average to above average return. The primary parent year for coho salmon this year is from the escapements of 2013. A few coho salmon have been entering the Yukon River but the majority of the run begins building in early August.

Fall Assessment Projects

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

The cumulative CPUE for the project through July 24 was 178.80 fall chum salmon, which is above the historical median of 166.88 for this date.  

Mountain Village Drift Test Fishing/Asacarsarmiut Traditional Council

The fall season project began July 18 at Mountain Village. The cumulative CPUE for the project through July 24 was 845.58 fall chum salmon, which is above the historical median of 296.18 for this date.

Sonar Project near Pilot Station/ADF&G

The sonar project near Pilot Station transitioned to fall season counts on July 19. The cumulative fall chum salmon passage estimate through July 23 was 217,000, which is above the median passage of approximately 74,000 fish for this date.

Age Composition Fall Season/ADF&G

Fall chum salmon age analysis from the LYTF has not been completed at this time. Based on last year’s run, the age-5 component is expected to be above average. Females currently represent 53% of the fish sampled (n=130), which is near the average of 51% for this date.

Fall Season Management Strategies

As noted above, the 2017 fall chum salmon preseason projection is for a run size greater than 1.1 million fish. This level of abundance is sufficient to meet escapement and subsistence needs, and provide a surplus for commercial and personal use purposes. The Coastal District, and Districts 1, 2, and 3, and the Innoko River subsistence fishing are under fall season management. In Subdistrict 4A, subsistence fishing will switch to a 5-day per week schedule on July 25, and the Koyukuk River as well as the lower river districts are open 24 hours a day, 7 days per week. Subsistence fishermen may use 7.5 inch or smaller mesh size gillnets and fish wheels. The remaining upriver districts and subdistricts will transition to fall season management as the fall chum salmon migration enters those areas.

Summer Assessment

As of July 23, approximately 44,000 Chinook salmon have been counted at the sonar project near Eagle, which is above the historical average of approximately 29,000 fish. Chinook salmon passage also surpassed the lower end of the Interim Management Escapement Goal at the Eagle sonar. Through July 19, approximately 45%, or 13,000 fish, of the Chinook salmon passage at the Eagle sonar were female. On average, about 41% of the passage at the Eagle sonar consists of female Chinook salmon. The first three pulses of Chinook salmon have been counted at the sonar and the fourth pulse should be passing the sonar now. The average historical midpoint at the sonar for Chinook salmon is July 20 for early run fish and July 24 for normal run fish. The 2017 Chinook salmon run is expected to surpass the upper end of the Interim Management Escapement Goal into Canada with sufficient surplus for the Canadian harvest share of the Total Allowable Catch.

The Chinook salmon escapement goal at the East Fork Andreafsky River has been met. Chinook salmon passage estimates at the Henshaw Creek and Gisasa River weirs are below average for this date. Unfortunately, high water conditions have hindered tower counts on the Salcha and Chena rivers; however, initial tower counts and sonar estimates indicate that escapement goals will likely be met. Post-season analysis is needed to confirm final passage estimates at these projects. Aerial surveys were conducted for Chinook and summer chum salmon last week. The aerial Chinook salmon Sustainable Escapement Goals (SEG) were met for the West Fork Andreafsky River, the Anvik River, and the Nulato River.

The escapement goal of at least 40,000 summer chum salmon at the East Fork Andreafsky River weir was achieved on July 9. The escapement goal of 350,000–700,000 summer chum salmon at the Anvik River sonar was achieved on July 14. Summer chum salmon passage estimates at the Gisasa River and Henshaw Creek weirs are well above averages for this date.

Summer Assessment Projects

Sonar Project near Pilot Station / ADF&G

The sonar project near Pilot Station has been fully operational since June 1.  As of July 23, the estimated cumulative Chinook salmon passage is 260,655 fish, which is above the historical average of 219,562 fish for years with early run timing. Preliminary run timing dates suggest the 2017 Chinook salmon run was approximately three days earlier than historical average run timing. As of July 18 the estimated cumulative summer chum salmon passage was 3,094,350 fish, which is well above the historical median of 1,875,491 summer chum salmon for this date. Chum salmon estimates after July 18 are assumed to be predominantly fall chum salmon. 

East Fork Andreafsky River Weir / USFWS

The East Fork Andreafsky River weir began operations on June 14. As of July 23, the estimated cumulative Chinook salmon passage is 2,902 fish, which is below the historical cumulative average of 3,765 Chinook salmon for this date. As of July 23, the estimated cumulative summer chum salmon passage is 53,462 fish, which is slightly below the historical median of 54,784 fish for this date. The sustainable escapement goals (SEG) are 2,100-4,900 Chinook salmon and greater than 40,000 summer chum past the weir project. Both of these escapement goals have been met.

Anvik River Sonar / ADF&G

The Anvik River sonar began operations on June 15. As of July 23, the estimated cumulative summer chum salmon passage is 412,535 fish, which is below the historical cumulative median of 433,008 for this date. The biological escapement goal (BEG) for summer chum salmon is 350,000–700,000 fish past the sonar project. Summer chum salmon passage exceeded the lower end of the escapement goal on July 14.

Gisasa River Weir / USFWS

The Gisasa River weir began operations on June 18. Chinook salmon passage, as of July 23, is estimated to be 1,005 fish, which is below the historical cumulative average of 1,886 for this date. Summer chum salmon passage, as of July 23, is estimated to be 70,074 fish, which is above the historical median of 39,026 summer chum salmon for this date.

Henshaw Creek Weir / USFWS

The Henshaw Creek weir began operations on June 26. Chinook salmon passage, as of July 23, is estimated to be 613 fish, which is below the historical cumulative average of 1,009 fish for this date. Summer chum salmon passage, as of July 23, is estimated to be 335,850 fish, which is well above the historical median of 107,969 summer chum salmon for this date.

Chena River Tower / ADF&G

The Chena River tower began operations on June 26. As of July 23, the estimated cumulative Chinook salmon passage is 1,516 fish and 3,961 summer chum salmon have been observed at the tower. These counts are considered incomplete due to 14 days of missed counts at the project. The BEG for Chinook salmon is 2,800–5,700 fish past the tower.

Salcha River Tower / ADF&G

The Salcha River tower began operations on June 27. As of July 23, the estimated cumulative Chinook salmon passage is 2,741 fish and 6,480 summer chum salmon have been observed at the tower. These counts are considered incomplete due to four days of missed counts at the project. The BEG for Chinook salmon is 3,300–6,500 fish past the tower.

Eagle Sonar / ADF&G

The Eagle sonar project began operations on July 1, which is one of the earliest start dates since the project began in 2005. As of July 23, approximately 43,522 Chinook salmon have been counted at the sonar project, which is above the historical cumulative average of 28,914 for this date. The lower end of the Interim Management Escapement Goal for Chinook salmon of 42,500-55,000 was exceeded July 23.

Age Composition

The age composition of 355 Chinook salmon sampled from the drift gillnets in the Pilot Station test fishery through June 25 was 7% age-4, 55% age-5, 35% age-6, and 3% age-7 fish. About 52% of the fish sampled were female. Age-5 fish and females were above average, age-6 fish were average, and age-4 fish were below average. The age composition of 463 Chinook salmon sampled from the LYTF set gillnets, through June 22, was 4% age-4, 47% age-5, 48% age-6, and 2% age-7 fish. About 44% of the fish sampled were female. The age composition of 489 summer chum salmon sampled from the LYTF drift gillnets through June 22 was 34% age-4, 63% age-5, and 3% age-6 fish. About 58% of the fish sampled were female. Age-5 fish were above average, age-4 fish were below average, and percent females were average.

Stock Identification

Genetic mixed stock analysis (MSA) on the first strata of Chinook salmon, which included early fish and the first pulse of Chinook salmon sampled at the Pilot Station sonar (May 31 to June 13), estimated 43% of the sampled fish were of Canadian-origin. Genetic MSA on the second strata, which included all of the second pulse of Chinook salmon (June 14-20), estimated 43% of the sampled fish were of Canadian-origin. Genetic MSA on the third strata (third pulse) of Chinook salmon (June 21-25) estimated 43% of the sampled fish were of Canadian-origin.

Four strata of chum salmon genetic samples have been processed in 2017. The strata from May 31–June 19 consisted of 99% summer chum salmon, 73% lower stocks, 23% were bound for the middle Yukon River and about 4% were bound for the Tanana River. The strata from June 20–June 26 also consisted of 99% summer chum salmon, 91% lower stocks, 5% were bound for the middle Yukon River and about 4% were bound for the Tanana River. The strata from June 27–July 9 consisted of 96% summer chum salmon, 69% lower stocks, 22% middle Yukon River stocks, and 5% Tanana River stocks there was also a small showing of fall stocks at 4%. The strata from July 10–18 consisted of 98% summer chum salmon, 71% lower stocks, 18% middle Yukon River stocks, and 10% Tanana River stocks and only 1% fall stocks.
