2019 Yukon River Summer Salmon Fishery News Release #23 Summer Update # 5, Yukon Area Salmon Fishery

Districts Affected: Yukon Area

The Chinook salmon run is currently coming in stronger than the run observed in 2018 and will most likely be within the preseason projection range of 168,000 to 241,000 fish. (Figure 1). The average first quarter point for Chinook salmon for a run with normal run timing at Pilot station sonar is June 18 and the midpoint is typically June 24. Like 2018, some subsistence harvest restrictions are necessary in order to meet escapement goals and harvest share objectives on a run of this size.

Summer chum estimates are well below average at the Pilot Station sonar, indicating the run is late and weaker than expected. However, summer chum salmon passage in the lower river increased dramatically during the last two days and passage at the sonar has exceeded the lower end of the drainage-wide escapement goal of 500,000 fish. Current projections indicate a commercial surplus available for harvest (Figure 2). The average first quartile and midpoint are on June 24 and June 30, respectively, at the sonar project for years with late summer chum salmon run timing.

The strong early trickle of Chinook salmon may be as far upriver as the Canadian border, and sonar counting operations near Eagle are beginning now. As of June 30, the first pulse of Chinook salmon should be in Rampart and above. A smaller, second, pulse of Chinook salmon should be in District 4-A lower. A third pulse of Chinook salmon is currently passing by the Pilot Station sonar. Early summer chum salmon may be near Nenana and the first large group of summer chum salmon should be near District 4-A. The largest group of summer chum salmon (over 300,000 fish) just passed the sonar in District 2 and should be entering District 3.

Genetic mixed stock analysis (MSA) on the early group and first pulse of Chinook salmon sampled at the Pilot Station sonar project (June 2 to June 23) indicated that 56% of the fish sampled were of Canadian-origin. Genetic MSA will continue throughout the season. The age composition of 390 Chinook salmon sampled from the drift gillnets in the Pilot Station test fishery through June 23 was 11% age-4, 52% age-5, and 36% age-6 fish. The percentage of fish that were female (48%) was above average.

The inseason salmon management teleconferences hosted by Yukon River Drainage Fisheries Association are held every Tuesday at 1:00 p.m. To participate, call (800) 315-6338, and enter code: YUKON# (98566#). Sharing your local knowledge, harvest information and fishing observations on these calls is very helpful for effective management.

Assessment Projects

Lower Yukon Test Fishery (LYTF)/ ADF&G and YDFDA

The combined cumulative Chinook salmon CPUE for the 8.5-inch set gillnet at the Big Eddy and Middle Mouth sites is 32.39, which is above the historical average of 20.81. The cumulative Chinook salmon CPUE in the 8.25-inch drift gillnet at the Big Eddy site is 351.30, which is below the historical average of 362.41. The combined cumulative summer chum salmon CPUE for the 5.5-inch drift gillnet at the Big Eddy and Middle Mouth sites is 5,475.78, which is below the historical median of 6,150.43 for this date. All CPUEs are current through June 30.

Operations at the LYTF have been altered from previous years, so caution should be taken when comparing current catch rates to historical catch rates. Any Chinook salmon healthy enough will be released alive from the test nets. Injured salmon and mortalities will be distributed to village elders by the Tribal Councils.

Sonar Project near Pilot Station/ ADF&G

The Pilot Station sonar is operating well and is not currently experiencing any issues with debris. Chinook salmon passage is estimated to be 155,319 fish, which is above the historical cumulative average of 138,044 fish. Summer chum salmon passage is estimated to be 570,564 fish, which is below the historical cumulative median of 1,093,691 fish. All passage estimates are current through June 30.

East Fork Andreafsky River Weir / USFWS

The East Fork Andreafsky River weir began operations on June 28, nearly 13 days late (due to high water). Chinook salmon passage is estimated to be 370 fish, which is above the historical cumulative average of 268 fish. Summer chum salmon passage is 520 fish, which is below the historical cumulative median of 10,283 fish for this date. All passage estimates are current through June 30. The sustainable escapement goal for summer chum salmon is 40,000 fish.

Anvik River Sonar / ADF&G

The Anvik River sonar began operations on June 16. Summer chum salmon passage, as of June 30, is 9,965 fish, which is below the historical cumulative median of 108,988 fish for this date. The biological escapement goal for Anvik summer chum salmon is 350,000–700,000.

Henshaw Creek Weir / TCC

The Henshaw Creek weir began operations on June 30 and 2 summer chum salmon were counted on that date.

Chena River Tower / ADF&G

The Chena River tower began operations on June 24. Chinook salmon passage is estimated to be 33 fish, which is below the historical cumulative average of 87 fish. Summer chum salmon passage is 27 fish, which is above the historical cumulative median of 0 fish for this date. All passage estimates are current through June 30. The BEG for Chinook salmon is 2,800–5,700 past the tower site.

Salcha River Tower / ADF&G

The Salcha River tower began operations on June 24. Chinook salmon passage is estimated to be 51 fish, which is below the historical cumulative average of 74 fish. No summer chum salmon have been counted at the sonar. All passage estimates are current through June 30. The BEG for Chinook salmon is 3,300–6,500 past the tower site.

Management Strategy

While the Chinook run projection indicates escapement goals and harvest shares should be met, some level of harvest restriction, similar to last year, is needed. Like last year, fishing has been reduced to half the regulatory (windows) fishing schedule in all districts, gillnets are being restricted to 6-inch or smaller mesh, and one fishing period per week has been cancelled, as needed, to allow fish to pass upriver. As the majority of Chinook are moving out of the lower river and chum numbers are increasing, gillnet restrictions are being relaxed to allow fishermen to target Chinook salmon, or chum salmon as needed.

Summer chum run projections have indicated a likely commercial surplus available for summer chum, though buyer capacity and incidental harvest of Chinook salmon will be considered for any future commercial openings.

Current Subsistence Management

As a reminder to fishermen, dip nets are now a legal subsistence gear type and are allowed during subsistence salmon gillnet openings. Subsistence fishermen may retain any Chinook salmon harvested in dip nets, gillnets and fish wheels, unless otherwise specified in the announcements. During salmon fishing closures, fishing for non-salmon is allowed, however, gillnets must be 4-inch or smaller mesh.
