The 2021 Yukon River Chinook salmon run will seemingly be a small one, in response to pre-season forecasts. Officials on each side of the border are involved that the run will as soon as once more fail to satisfy conservation and harvest objectives.
Somewhere between 42,000 and 77,000 Canadian-origin fish are anticipated to make the journey from the Bering Sea this yr, Alaska and Yukon specialists informed attendees throughout the Yukon River Panel’s pre-season assembly on Tuesday. The most probably run measurement can be 57,000, they stated.
That’s smaller than the pre-season outlooks for 2020 and 2019 — and each these years ended disastrously when it got here to getting sufficient salmon throughout the border.
Under a global treaty, Canada and the U.S. are presupposed to work collectively to make sure no less than 42,500 fish make it to their spawning waters in Yukon. That spawning escapement purpose hasn’t been met since 2018 — final yr, solely about 33,000 Chinook made it.
More fishing restrictions ‘seemingly’ in Alaska
“Based on our outlook and recent escapements, our management will be more restrictive than it was in 2020,” Denna Jallen, the Alaska Department of Fish and Game’s (ADFG) summer season season administration biologist, informed assembly attendees.
“In 2020 we had fishing restrictions — in 2021, we’re likely going to have more fishing restrictions.”
Alaska will probably be “managing conservatively” this yr till no less than the mid-point of the run, Jallen defined. Depending on what the precise numbers seem like, the state could implement full fishing closures.
It’s extremely unlikely that the run will permit for a full subsistence harvest in Alaska, she stated, and whereas fishermen will probably be allowed to catch different species, ADFG can be placing gear restrictions in place as the primary group of Chinook make their method upstream.
Besides getting sufficient fish into Canada, Jallen stated there have additionally been worries about getting sufficient Chinook into Alaska tributaries. The forecast for your complete Chinook run is 102,000 to 189,000 fish, in response to Jallen. Runs smaller than 160,000 typically fail to satisfy escapement objectives.
‘Very restricted’ Yukon First Nations harvest
Jesse Trerice, Yukon River fishery supervisor for Fisheries and Oceans Canada, stated the 2021 outlook did not “bode well for Canadian harvest opportunities.”
Only Yukon First Nations have been allowed to fish for Chinook on the Yukon River for years now as a result of steadily-declining run sizes. Trerice stated they might seemingly have a “very limited” fishery this yr, with public angling and business and home fisheries closed as regular.
“We can assume that there’s a reasonable probability that the Canadian harvest share could be less than 1,400 Chinook, which is about less than a fifth of a full First Nation fishery allocation,” she stated.
Depending on the in-season numbers, there may be a full closure on harvest if the variety of Canadian-origin Chinook is available in on the decrease finish of the forecast and the spawning escapement purpose cannot be met.
Chinook salmon sometimes start getting into the Yukon River in late May and June.
