Dispute about salmon and whales between Alaska and Washington again before federal regulators

October 10, 2023 — The fishing of chinook or king salmon is back on the desk of the National Marine Fisheries Service, part of the whipsaw rulings this past summer that saw the king salmon season shut down — and then reinstated — as a case brought by environmentalists wound its way through the courts.

NMFS issued a notice Wednesday it is beginning work on an Environmental Impact Statement (EIS) and a review of alternatives to its incidental take statement (ITS). The ITS is the amount of take allowed to occur in compliance with the Endangered Species Act.

NMFS is accepting public comments through noon on Nov. 20, said Gretchen Harrington, assistant regional administrator for the Sustainable Fisheries Division. The EIS is required under the National Environmental Policy Act (NEPA).

The case, Wild Fish Conservancy v. Quan, was filed in U.S. District Court in March 2020. Lawyers for WFC argued fishery managers and representatives of the Pacific Salmon Treaty were ignoring their own research by allowing fishing that harmed the endangered king salmon and the southern resident killer whale population, which feeds on them.

ALASKA: Why sockeye flourish and chinook fail in Alaska’s changing climate

July 27, 2023 — University of Washington ecologist Daniel Schindler is at the mouth of a salmon stream at Lake Nerka, in Southwest Alaska. It’s roiling with fish.

“They sort of pile up in balls of thousands of fish for a couple of weeks. I think that’s when they’re doing their final maturation,” he said of the sockeye mob. “They’re jostling with each other and splashing, occasionally jumping.”

Schindler is in his 27th year of field work, studying Bristol Bay sockeye. This year is on par with the sockeye abundance Bristol Bay has seen in the last decade, he said, which is far higher than the historical average.

The unlikely hero of this story of plenty: Climate change.

“We tend to think of climate warming is bad news for wild animals,” he said. “But for sockeye Bristol Bay warming has been good news.”

For other salmon, climate change is a villain.

Chinook – or king – salmon are in terrible decline all over the state, and especially dire on the Yukon River. Meanwhile, sockeye – or reds – are having another banner year in Bristol Bay, and everywhere.  Scientists say they don’t know exactly why one salmon species is doing so well while the other is in crisis, but some clues are coming into sharper focus.

One key difference, Schindler said, is what kind of river habit each species needs.

Sockeye use lakes as their nurseries. Since the 1980s the water in those lakes has warmed significantly. The warmth stimulates plankton to reproduce more, and young sockeye eat plankton. Fifty years ago, Schindler said, a lot of sockeye spent two years in Lake Nerka before heading out to sea.

“And now they grow so fast that nearly all of them leave after a single year in freshwater, which is a reflection of the fact that the freshwater systems have become more productive,” he said.

Warmer Ocean Temperatures Increase Risk of Salmon Bycatch in Pacific Hake Fishery

July 17, 2023 — Rates of Chinook salmon bycatch in the Pacific hake fishery rise during years when ocean temperatures are warmer, a signal that climate change and increased frequency of marine heatwaves could lead to higher bycatch rates, new research indicates.

During years when sea surface temperatures were higher, including during a marine heatwave, Chinook salmon were more likely to overlap with the Pacific hake and raise the risk of bycatch as they sought refuge from higher temperatures.

The findings, based on 20 years of bycatch data and ocean temperature records, provide new insight into the ecological mechanisms that underlie bycatch, which is the incidental capture of a non-targeted species, said the study’s lead author, Megan Sabal.

“The impact of ocean warming on bycatch has potential cultural, economic and ecological consequences, as the hake and salmon fisheries are each worth millions of dollars and salmon are critical to both Indigenous tribes’ cultural heritage and healthy ecosystems,” said Sabal, who worked on the project as a postdoctoral scholar at Oregon State University.

Pacific hake, also known as Pacific whiting, is the largest commercial fishery by tonnage on the U.S. West Coast. The rate is low, but bycatch remains a concern for the Chinook salmon population, said Michael Banks, a marine fisheries genomics, conservation and behavior professor at Oregon State University and a co-author of the study.

The research was just published in the journal Fish and Fisheries.

Pacific hake school in midwater depths off the West Coast from southern Baja California to the Gulf of Alaska. Hake is commonly used in surimi, a type of minced fish used to make imitation crab.

ALASKA: Dunleavy again vetoes research project on salmon bycatch

June 23, 2023 — Among the projects Gov. Mike Dunleavy vetoed from the state budget on Monday was salmon research to help determine the causes of the chinook and chum crisis in western Alaska.

Dunleavy vetoed $513,000 for research on the origins of salmon caught by accident in the Bering Sea pollock fishery, as well as the origin of salmon intercepted by fishermen off the Alaska Peninsula in what’s known as “Area M.” Dunleavy vetoed the project last year, too.

“You never know what’s going to come of these budgets. But this is quite a disappointment, again,” said Karen Gillis, program director of the Bering Sea Fishermen’s Association. The association was to receive the money and pass it on to a partnership of federal and university scientists.

OREGON: Oregon gov. calls for fishery resource disaster over Chinook season closure off West Coast

April 24, 2023 — Oregon Governor Tina Kotek is calling on the U.S. government to declare a federal fishery resource disaster over the closure of the 2023 season for all commercial and most recreational Chinook salmon fishing along much of the West Coast.

This month, the Pacific Fishery Management Council recommended closing all commercial ocean fishing ror Chinook from Cape Falcon on Oregon’s northern coast to Mexico. The action is in response to low Chinook returns.

ALASKA: ADF&G predicts weak pink salmon harvest, tightens Chinook harvest restrictions

April 17, 2023 — Southeast Alaska’s pink salmon run is predicted to be weak this summer. The region’s commercial harvest is expected to increase by just five percent this year compared to last year, according to a report from the Alaska Department of Fish & Game released earlier this month. But it’s forecast to be more than a 60% drop from the last odd-year harvest in 2021 – pink salmon runs in Southeast peak in odd years and fall in even years.

The 2023 pink salmon harvest is predicted to be around 19 million fish, with a probable range of between 12 and 19 million. That’s what the department classifies as a weak run. It’s nowhere near Southeast’s record harvest of 2013, which saw more than 89 million pink salmon.

The estimate comes mostly from analysis of juvenile pink salmon abundance indicators collected by researchers in Southeast in previous years.

California salmon fishing slated to shut down this year due to low stock

April 10, 2023 — Chinook salmon fishing off the California coast will be called off until next spring in anticipation that a near-record-low number of fish will return to the state’s rivers to spawn.

The recommendation was made by the Pacific Fishery Management Council, a federal commission that oversees West Coast fisheries. It will need to be approved by the National Marine Fisheries Service by May 16.

The measure, unseen in 14 years, would temporarily ban both commercial and recreational salmon fishing in the state. Much of the fishing off the coast of neighboring Oregon would also be canceled until 2024.

Chinook salmon are the “largest and most highly prized” of all the salmon in the Pacific ocean, according to the council. But over the years, the species has become increasingly endangered as a result of drought, heat waves and agriculture.

OREGON: Likely closure to Chinook salmon season in Oregon due to California drought

April 4, 2023 — Recent years brought a sizeable dip in ocean Chinook salmon numbers out of California causing low returns throughout Oregon, according to the Pacific Fishery Management Council (PFMC).

This week, a meeting of the PFMC will decide whether to close fall Chinook salmon fishing in Oregon this summer.

Federal agencies, tribal members, state representatives, and members of the fishing community comprise the Pacific Fishery Management Council.

The Council began a week-long meeting in California Monday to design a plan to protect this year’s run of fall Chinook salmon.

“They look at the data, the reports from the scientists, and the estimates of what the salmon season is going to look like in terms of numbers of fish coming back and then they determine the best way to shape the fishing season,” said Michael Milstein with the National Oceanic and Atmospheric Administration (NOAA).

OREGON: ‘It’s a painful year’

April 4, 2023 — Mark Newell typically buys and processes a lot of salmon and tuna. But this year, he expects that a lack of salmon fishing off Oregon’s southern coast during the spring and summer seasons could wipe out a major chunk of his income.

Newell, based in Newport and a member of the Oregon Salmon Commission, has been a commercial fisherman since the 1970s and, in the past 15 years, a wholesale seafood buyer and processor. Ocean Beauty in Astoria is one of his accounts.

“It’s a tough deal,” he said. “It’s just tough to have no options.”

He is referring to ocean salmon season alternatives proposed by the Pacific Fishery Management Council, the entity responsible for setting ocean salmon seasons off the Pacific Coast.

In March, the council unveiled its alternatives for the summer salmon seasons and the picture was bleak.
