House panel OKs spending to control sea lions

July 19, 2021 — U.S. Reps. Jaime Herrera Beutler (WA-03) and Kurt Schrader (OR-05) on July 14 announced that a joint Community Project Funding request they supported to protect endangered salmon, steelhead and other native fish species within the Columbia River system from sea lion predation, has been approved for $892,000.

The House Appropriations Committee — Subcommittee on Commerce, Justice, Science, and Related Agencies included the funding request as part of its Fiscal Year 2022 spending plan. The Washington Department of Fish and Wildlife is the recipient and would use the funding on equipment and related needs to remove sea lions in the Columbia River and its tributaries as outlined by a 2018 law Herrera Beutler and Schrader advocated.

The U.S. House as a whole and the U.S. Senate also must approve the spending before it will be dispersed to WDFW.

According to a press release from the representatives, the need for sea lion removal has sharply increased in recent years, as a record number of California and Steller sea lions come to the Columbia, Willamette and Snake Rivers, posing an extreme threat to struggling salmon, steelhead, sturgeon and other fish in the waterways. NOAA Fisheries says sea lions especially prey on adult salmon and steelhead migrating upriver from the ocean to Bonneville Dam, Willamette Falls and other tributaries to the Columbia River, further threatening the growth of native fish populations.

Is That Steller Sea Lion in Distress? Waving? Or Is It …Thermoregulation?

May 7, 2021 — The following was released by NOAA Fisheries:

Imagine that you are enjoying a wonderful day along Alaska’s rocky shores when suddenly you see something strange in the water. Is that an orca? You look through your binoculars and realize it is a Steller sea lion. You see its flipper in the air, and it only surfaces its head to breathe once in a while. Is it sick or injured? Or is this normal behavior?

NOAA Fisheries often receives reports of Steller sea lions exhibiting this behavior from concerned citizens who think the sea lion may be in distress.

“When people get hot or cold, they can remove or add a layer of clothing,” explains Steller sea lion expert Kim Raum-Suryan of NOAA’s Alaska Regional Office. “Since Steller sea lions don’t have this option, they do something a little different. They instead have this amazing ability to use thermoregulation—in other words, to regulate their own body temperature. “

A Steller sea lion’s core body temperature is about 100°F. Heat loss in water is about 25 times faster than in air. Steller sea lions deposit most of their body fat into a thick layer of blubber just under the skin. This blubber layer insulates the sea lion’s body from the cold water and provides an excess energy reserve.

However, the flippers are poorly insulated, with the blood vessels close to the surface of the skin. Sea lions often regulate their own body temperature by lifting and exposing one or more flippers as they are floating on the surface of the water. The blood vessels just under the skin dilate and either absorb heat from, or release heat to, the environment. Absorbed heat is then circulated to the rest of the body.

If you ever see a stranded, injured, entangled, or dead Steller sea lion or other marine mammal, please call the NOAA Fisheries Alaska Statewide 24-hour Stranding Hotline at (877) 925-7773. But the next time you see a sea lion or a group of sea lions with their flippers extended out of the water, there’s no need to call. This is just normal sea lion behavior … but you can wave back if you want to!

NMFS authorizes sea lion removals to save Columbia River salmon

August 28, 2020 — Up to 716 sea lions may be removed from a Columbia River management zone over the next five years to reduce the animals’ impact on salmon and steelhead populations, under a new federal authorization granted to states and tribes in the U.S. Northwest.

In 2018, the U.S. Congress amended the Marine Mammal Protection Act to allow removal of sea lions from a stretch of the Columbia River between the I-205 bridge on Portland’s east side and McNary Dam. The change also allowed for removing sea lions from Columbia River tributaries below the McNary Dam that are spawning habitat for threatened or endangered salmon and steelhead runs.

Federal officials approve sea lion kill program along the Columbia River

August 18, 2020 — As expected, federal officials on Friday approved a program to kill up to 716 sea lions along a nearly 200-mile stretch of the Columbia River and its tributaries in an effort to protect salmon at risk of extinction.

The program is a significant step-up in existing efforts, and will be in place for five years.

Targeted are both Steller’s and California sea lions, which will be darted with lethal levels of tranquilizing drugs by authorized teams from states and tribes.

West Coast Waters Shift Toward Productive Conditions, But Lingering Heat May “Tilt” Marine Ecosystem

March 6, 2020 — The following was released by NOAA Fisheries:

Burgeoning populations of anchovy and a healthy crop of California sea lion pups reflected improved productivity off parts of the West Coast in 2019. However, lingering offshore heat worked against recovery of salmon stocks and reduced fishing success, a new analysis reports.

The California Current Ecosystem Status Report explains that ocean conditions off the West Coast remain unusually variable. This has been the case since the arrival of a major marine heatwave in 2014 known as “The Blob.” NOAA Fisheries’ two West Coast laboratories, the Northwest Fisheries Science Center and Southwest Fisheries Science Center, issue the report each year to the Pacific Fishery Management Council.

“There is not a real clear picture here,” said Chris Harvey, co-editor of the report developed by the two laboratories’ Integrated Ecosystem Assessment approach. The approach integrates physical, biological, economic, and importantly social conditions of the California Current marine ecosystem into the decision-making process. “On the one hand, we have a lot of anchovy out there. On the other hand, we also have a lot of warm water. That is not usually a sign of improved productivity.”

Sea lions are cash cows in the Bay Area. Farther south, fishermen say, ‘Shoot ‘em’

January 13, 2020 — Sea lions are increasingly living in parallel universes along the California coast, a disparity best observed amid the noisy, stinking spectacle that rolls out daily at San Francisco’s Pier 39 shopping center.

There, hundreds of these enormous, mostly male California sea lions bark, defecate, urinate and regurgitate, but are immensely popular with tourists. As a result, the blubber boys are treated like royalty.

“The sea lions are a godsend: a natural attraction that’s phenomenal for business,” Sheila Chandor, Pier 39 harbormaster, said on a recent weekday as tourists snapped selfies against a backdrop of sea lions piled up like cordwood on docks.

Bill Monroe: Oregon seeking expanded sea lion controls following success of steelhead protections at Willamette Falls, Bonneville Dam

October 28, 2019 — Having fended off the threat of extinction of wild winter steelhead over Willamette Falls, Oregon biologists are now joining counterparts in Washington, Idaho and Native American tribes to expand that success.

Tuesday is the deadline set by the National Marine Fisheries Service for comments on a state and tribal proposal to reduce protections for both California and Steller sea lions in the Columbia river and its tributaries.

Changes in federal rules to streamline the control of sea lions have been approved by congress, but the states and tribes must still apply for authorization.

Current permits only allow the capture and killing of specific California sea lions at either Willamette Falls or Bonneville Dam.

The new proposal calls for the lethal take and euthanization of both California and Steller sea lions from anywhere in the Columbia River between the Interstate 205 bridge upriver to McNary Dam and from any lower Columbia tributaries such as the Willamette, Cowlitz and Lewis rivers. While there are no known sea lions upriver from The Dalles Dam (and only rumors of one between there and Bonneville), the area brings key fishing areas into the fold for six Native American tribes.

New plan targets salmon-eating sea lions in Columbia River

September 3, 2019 — More than 1,100 sea lions could be killed annually along a stretch of the Columbia River on the Oregon-Washington border to boost faltering populations of salmon and steelhead, federal officials said Friday.

The National Marine Fisheries Service said it’s taking public comments through Oct. 29 on the plan requested by Idaho, Oregon, Washington, and Native American tribes.

The agency says billions of dollars on habitat restoration, fish passage at dams and other efforts have been spent in the three states in the last several decades to save 13 species of Columbia Basin salmon and steelhead protected under the Endangered Species Act.

WASHINGTON: Outdoor notes: Application submitted to lethally remove sea lions from Columbia River

June 20, 2019 — The Washington Department of Fish and Wildlife, in partnership with several stakeholders, has submitted an application to remove by lethal force, California and Stellar sea lions that are preying on protected salmon and steelhead runs in the Columbia River and many of its tributaries.

Sea lion numbers have been growing alarmingly in the last decade, and they have been gathering below the Bonneville Dam to intercept salmon and steelhead as they make their way upstream. Many of the fish they are feeding on are listed as threatened or endangered under the Endangered Species Act.

Many runs of salmon, particularly chinook, are struggling. Chinook runs this year are so low that fishing closures have been enacted.

“The vast majority of these animals remain in coastal and offshore waters, but several hundred have established themselves in upriver locations,” said Kessina Lee, Region 5 director with WDFW in a news release. “Where salmon and steelhead numbers are low, any unmanaged increase in predation can cause serious problems.”
