Fisheries Managers Face Mixed Forecast For Northwest Salmon, Concerns Over Endangered Orca

March 12, 2019 — About this time every year, the Pacific Northwest gets a report card from the natural world. It comes in the form of salmon run forecasts and gives us an indication of how healthy the Pacific Ocean and our rivers and streams are.

The grades are in, and here’s what you need to know about our scores.

How’d we do this year?

It’s definitely looking like we’re in for a “there’s room for improvement” kind of year.

Every spring, a group called the Pacific Fishery Management Council gets together and look at the salmon forecasts from the Puget Sound all the way down to the Sacramento River in California. They use this data to decide at a week-long meeting in April what overall catch limits will be. This catch allowance is then split between commercial, recreational and tribal fishermen in the Pacific Northwest. The goal is to make sure we don’t catch more salmon than the numbers can actually support.

Feds could restrict Pacific Ocean fishing over endangered orcas, NOAA letter says

March 8, 2019 — The National Oceanic and Atmospheric Administration (NOAA) is taking a fresh look at whether new fishing restrictions are needed to help prevent the extinction of endangered southern resident killer whales that frequent Puget Sound.

New evidence about the fish the whales depend on and the risk posed to orcas by depleted prey has caused the agency to write a letter of guidance to the Pacific Fishery Management Council, indicating the agency is examining whether new restrictions are needed — particularly on fisheries in the Lower Columbia and Sacramento River and on fall-run chinook salmon in the Klamath River.

NOAA in 2009 concluded fisheries did not jeopardize the survival and recovery of killer whales.

But since then, “a substantial amount of new information is available on SRKW (southern resident killer whale) and their prey,” and has the agency wanting to take another look at fishing, Barry Thom, regional administrator for NOAA’s West Coast region, wrote to Phil Anderson, chairman of the council, on Wednesday.

Decline of salmon adds to the struggle of Puget Sound’s orcas

February 26, 2019 — The crew of the Bell M. Shimada hauled in the net, long as a football field and teeming with life. Scientists, off the coast of Washington for a week on this June research trip, crowded in for a look.

Each tow of the net revealed a changing world for chinook salmon, the Pacific Northwest’s most famous fish — and the most important prey for the southern-resident killer whales that frequent Puget Sound.

There were salmon the scientists expected, although fewer of them. But weirdly also pompano, tropical fish with pretty pink highlights, iridescent as a soap bubble, that were not supposed to be there at all.

What the scientists see each year on this survey underway since 1998 has taken on new importance as oceans warm in the era of climate change.

Decadelong cycles of more and less productive ocean conditions for salmon and other sea life are breaking down. The cycles of change are quicker. Novel conditions in the Pacific are the new normal.

“It used to be up, or down. Now, it is sideways,” said physiological ecologist Brian Beckman, of the National Oceanic and Atmospheric Administration’s Northwest Fisheries Science Center in Seattle.

That’s bad news for endangered orcas that rely on salmon for food. When salmon decline, orcas suffer.

Orcas thrive in a land to the north. Why are Puget Sound’s dying?

November 16, 2018 — Bigger and bigger, with a puff and a blow, the orca surfaces, supreme in his kingdom of green.

Northern resident orcas like this one live primarily in the cleaner, quieter waters of northern Vancouver Island and Southeast Alaska, where there also are more fish to eat. They are the same animal as the southern residents that frequent Puget Sound, eating the same diet, and even sharing some of the same waters. They have similar family bonds and culture.

The difference between them is us.

The southern residents are struggling to survive amid waters influenced by more than 6 million people, between Vancouver and Seattle, with pollution, habitat degradation and fishery declines. The plight of the southern residents has become grimly familiar as they slide toward extinction, with three more deaths just last summer. Telling was the sad journey of J35, or Tahlequah, traveling more than 1,000 miles for at least 17 days, clinging to her dead calf, which lived only one half-hour.

Impossible Choices: The Complicated Task of Saving Both Orca and Salmon

September 10, 2018 — Decades of politics and foot-dragging have stymied the recovery of threatened and endangered Chinook salmon, while an iconic population of killer whales that depends on them veered toward extinction. Now, a last-ditch effort to save the whales may also be what thwarts the recovery of Chinook.

The Southern Resident killer whales are dying. An extended family of 75 orcas living year-round in the sea surrounding the San Juan Islands near Seattle, their numbers never fully rebounded since aquariums that later became SeaWorld captured a third of them in the late 1960s.

And there are other culprits.

Cargo ships and whale-watching boats zip through the Salish Sea, adding noise that interferes with the whales’ ability to locate each other and their prey. The water they live in is toxic. The Puget Sound outside Seattle is tainted with flame retardant, and PCBs and pollutants gush from nearby rivers into the sea.

The Chinook salmon they eat to live are contaminated with mercury, lead and organic compounds like PCBs. The Washington state Department of Health advises humans to limit their consumption of Chinook salmon to eight ounces per week. But Southern Residents eat dozens of the fish per day.

Not only is their food toxic, there’s also less of it than ever before. Five populations of Chinook the whales depend on are listed as threatened; a sixth is endangered. And they’re smaller, declining in size by 10 percent since the late 1970s, according to research published February in the scientific journal Fish & Fisheries.

Scientists Working On Orca Recovery Not Surprised By Recent Tragedies

August 7, 2018 –A multitude of factors are harming Puget Sound’s local population of endangered orcas: water pollution, noise, loss of habitat.

But topping that list right now for many scientists is recovery of their primary food source: Chinook salmon.

The tragic scenes captured on the water over the past week – of the grieving orca J35 incessantly carrying her deceased calf, and of 4-year-old J50 ill and starving –  are sad events, but not surprising to scientists working on orca recovery.

They say they established years ago that when Chinook salmon are scarce, local orcas become sick and unable to effectively reproduce.

“This is just a really conspicuous example of it,” said Sam Wasser, who directs the Center for Conservation Biology at the University of Washington.

He’s part of a team of scientists that has done DNA and hormone analysis of orca scat collected by sniffer dogs. They’ve proved that when pregnant orcas are low on food and start metabolizing their blubber, toxins are released into their bloodstream that cause them to miscarry.

Study Shows Importance Of Puget Sound Chinook Production To Starving Orcas

July 26, 2018 –A new analysis is showing the importance of Puget Sound Chinook for the inland sea’s orcas.

Fall kings from the Nooksack to the Deschutes to the Elwha were ranked as the most important current feedstocks for the starving southern residents, followed by Lower Columbia and Strait of Georgia tribs.

For the analysis, NOAA and WDFW sampled orca doots to “assist in prioritizing actions to increase critical prey for the whales.”

Nutritional stress has been identified as among the chief causes of their declining numbers, and the news comes as officials report a newborn calf died off Victoria yesterday. Just half of the 28 reproductive-age “blackfish” have produced calves in the last 10 years, another report said.

“Ramp up the hatchery production. Do it now. It’s the only way,” says Tom Nelson, co-host of Seattle outdoors radio show The Outdoor Line on 710 ESPN.

He was reacting this morning while fishing for coho at Possession Bar to a Seattle Times scoop on the findings.

Orca population hits 30-year low in Puget Sound

July 11, 2018 — The Southern Resident orca pods are in a tough spot — literally.

Their primary food source is dying off; the Trans Mountain Pipeline is expanding, which will increase the number of tankers trucking through the orcas’ habitat by seven times, among other exposure risks like noise and spills.

And now comes the latest spot of bad news: For the last three years not one calf has been born to the shrinking pods of the black-and-white killer whales in the Pacific Northwest, resulting in a 30-year low in orca population.

The annual census of Puget Sound’s resident orcas found that just 75 killer whales, across the three Southern Resident pods (J, K, and L), are still swimming through the Pacific Northwest waters. The J pod has 23 members, while K has 18, and L has 34.

In addition to finding no new births of Southern Residents, the census reported two missing and presumed dead members, 23-year-old Crewser (also known as L-92), and a 2-year-old calf named Sonic (J-52).

Mussels test positive for opioids in Seattle’s Puget Sound

May 29, 2018 — Scientists at the Washington State Department of Fish and Wildlife have found that mussels in Seattle’s waters are testing positive for opioids.

The finding suggests “a lot of people” are taking oxycodone in the Puget Sound, researchers say.

Scientists used mussels as a way to test pollution in Seattle’s waters and discovered high enough oxycodone levels for the shellfish to test positive.

Mussels do not metabolise opioids, but some fish can become addicted.

Mussels are filter-feeders, which means they filter water for nutrients to nourish themselves. In the process, they end up storing pollutants in their tissues, which makes them a prime indicator species.

State researchers distributed clean mussels around the Puget Sound and extracted them months later to test the waters.

Of the 18 locations scientists used, three showed traces of oxycodone. The drug traces were not enough to get any humans high from consumption, but enough to indicate a problem, officials said.

“What we eat and what we excrete goes into the Puget Sound,” Jennifer Lanksbury, a biologist at the Washington Department of Fish and Wildlife, told CBS News affiliate KIRO.

“It’s telling me there’s a lot of people taking oxycodone in the Puget Sound area.”

Washington: Some Puget Sound Tribal Dungeness Crab Fisheries Will Remain Closed This Year

May 14, 2018 — SEAFOOD NEWS — The Washington Department of Fish and Wildlife announced Thursday that two marine areas in south Puget Sound will not open for crab fishing this summer to allow Dungeness crab populations to rebuild.

Tribal commercial crab fisheries will remain closed in marine areas 11 (Tacoma/Vashon Island) and 13 (south Puget Sound) this summer. Recreational crab fisheries also will not open in those areas this year.

State and tribal co-managers are developing crabbing seasons for the rest of Puget Sound and plan to announce those later this month.

“We are still working on setting crab seasons but wanted to give people early notice about these closures, which is a change from previous years,” WDFW Puget Sound shellfish manager Bob Sizemore said in a press release. Sizemore said the department will continue working to structure fisheries in each Puget Sound region, but he does not anticipate closures similar to those in marine areas 11 and 13.

The populations of harvestable Dungeness crab are low in both areas 11 and 13, based on pre-season test fisheries, Sizemore said. Additionally, Dungeness crab harvests have fallen 88 percent in Marine Area 11 and 90 percent in Marine Area 13 since the 2014-15 season. Input from recreational crabbers also indicates support for the closures.

“We are taking this step to protect crab in these areas and allow the populations to rebuild,” Sizemore said.

Water currents can carry young crab long distances, making it possible for crab larvae from robust populations to settle and grow in areas 11 and 13, Sizemore said. But it can take several years for a newly settled Dungeness crab to grow and reach the minimum harvestable size of 6-¼ inches.

A variety of factors could be contributing to the declining population of crab in areas 11 and 13, Sizemore said. These include reduced survival of crab larvae, a higher-than-normal mortality rate for juvenile crab, or changing ocean conditions such as elevated surface water temperatures.
