Saving Seafood

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.

Canada proposes more habitat protection for southern-resident orcas

September 6, 2018 — Canada is taking steps to expand habitat protection for killer whales to boost survival of the critically endangered southern-resident population.

The Department of Fisheries and Oceans Canada announced Wednesday the department is initiating a 60-day comment period on creating new areas of critical habitat for the whales. One area is off the coast of southwestern Vancouver Island, including Swiftsure and La Pérouse banks (important for both northern and southern residents). The other is in Dixon Entrance, along the north coast of Graham Island from Langara to Rose Spit (important for northern residents).

The move to expand habitat protection comes on top of a reduction by the department of chinook salmon harvest by up to 35 percent for the 2018 fishing season, with a full closure of commercial and recreational fish for chinook in three key foraging areas for the southern residents: the Strait of Juan de Fuca, the Gulf Islands and the mouth of the Fraser River. These measures, enacted June 1, will continue until Sept. 30, and include increased monitoring to assess the effectiveness of the closures.

The critical-habitat designations could lead to further fishing reductions as well as restrictions on vessel traffic. The survival of southern-resident orcas — which are actually a large dolphin — is threatened because of underwater noise that disrupts their ability to hunt, as well as toxins and reduced availability of their primary prey, chinook salmon.

‘Our killer whales aren’t doing well:’ Lawsuit aims to protect struggling orcas

August 20, 2018 — Southern Resident Killer Whales are endangered and in decline.

Thursday a national environmental group filed a lawsuit against the Trump Administration. According to the suit, the National Marine Fisheries Service has failed to protect the winter habit of the Orcas.

“Our killer whales aren’t doing well,” said Sarah Yhlemann, a senior attorney for the Center for Biological Diversity who filed the lawsuit.

For 17 days a grieving mother Orca carried her dead calf more than 1,000 miles through the waters of the Salish Sea. An act of grief that environmentalist claim highlights the need to help the troubled Orcas.

“We know that protecting the whales themselves is absolutely important, but protecting their habit is really important too,” said Yhlemann.

The suit says NOAA has failed to act on a 2014 petition that includes expanding habitat protections to the Orcas’ winter foraging and migration areas off the coasts of Washington, Oregon and California.

“Right now their full habitat is not protected for the winter and travel down the coast, they don’t have habit protections,” said Yhlemann.

The lawsuit is asking for what the law requires for endangered species: to protect the entire habit of the Southern Resident killers whales.

The animals were listed as endangered under the Endangered Species Act in 2005, after the center sued to get the status. The following year, the fisheries service designated the inland waters of Washington state as critical habitat. The designation means federal agencies must ensure that activities they pay for, permit or carry out do not harm the habitat.

Group sues to expand protected orca habitat along West Coast

August 17, 2018 — An environmental group sued President Donald Trump’s administration Thursday to make officials move more quickly to protect the Pacific Northwest’s endangered orcas.

The recent grieving of one whale for her dead calf and scientists’ extraordinary attempts to save another from starvation highlight the urgency of their plight, the Tucson, Arizona-based Center for Biological Diversity said as it filed the lawsuit in U.S. District Court in Seattle.

There are just 75 orcas remaining in the Pacific Northwest population, the lowest number in 34 years. They’re struggling with a dearth of chinook salmon, their preferred prey, as well as toxic contamination and vessel noise.

The lawsuit says the National Marine Fisheries Service has failed to act on the center’s 2014 petition to expand habitat protections to the orcas’ foraging and migration areas off the coasts of Washington, Oregon and California — even though the agency agreed in 2015 that such a move was necessary.

The center says the protections would help reduce water pollution and restrict vessel traffic that can interfere with the animals.

“Time is running out fast for these magnificent, intelligent orcas,” Catherine Kilduff, an attorney with the organization, said in an emailed statement. “It’s heartbreaking to watch them starving to death and mourning their dead calves. Every day that Trump’s people delay action is a step toward extinction for these whales.”

An Ailing Orca Was Given Medication in the Wild for the First Time Ever

August 13, 2018 — A team of experts injected an ailing orca calf with a dose of antibiotics, in a medical intervention that’s never been tried before on a wild killer whale.

A team of biologists from NOAA Fisheries, Vancouver Aquarium, and other institutions have been tracking the three-year-old orca, named J50, or Scarlet, for weeks. They’re not entirely sure what’s wrong with her, but she’s dangerously underweight and often lethargic. Scarlet is a member of the J-Pod, a group of about 76 critically endangered southern resident orcas, or killer whales. Maintaining the life of each pod member, females especially, is crucially important, hence the extraordinary and unprecedented measure to administer medication.

Yesterday, Vancouver’s head veterinarian, Martin Haulena, managed to visually inspect Scarlet from a boat near Washington state’s San Juan Island. With the help of his team, Haulena administered a dose of antibiotics at close range using a dart, as AP reports. It’s the first time that a killer whale has been given medication while living in the wild, the CBC reports.

“Response teams reached J-Pod in Canadian waters and followed them into U.S. waters near San Juan Island. While very skinny and small, J50/Scarlet kept up well with her mother and siblings,” explained NOAA Fisheries in a press release. “Vancouver Aquarium’s veterinarian and the team conducted a visual assessment, obtained a breath sample that will help assess any infection, and administered antibiotics through a dart.”

Other orcas in Scarlet’s pod are not malnourished, so food shortage is not considered the problem.

Vets ready for rare efforts to save ailing endangered orca

August 8, 2018 — Experts are preparing rare emergency efforts to administer antibiotics or feed live salmon to try to save a young emaciated orca that’s part of a critically endangered pod of killer whales.

But veterinarians haven’t spotted the 3½-year-old female killer whale in several days. They are waiting for her to show up again in Washington state waters so they can zip out on a boat to do a health assessment, said Teri Rowles, marine mammal health and stranding coordinator for NOAA Fisheries.

The whale known as J50 is underweight and may have an infection.

“It is very possible that she has succumbed at this point and that we may never see her again,” Rowles told reporters Tuesday. “We are hopeful that there’s still a chance that we will be able to assist her with medical treatment to give her enough time to get nourishment and treat infections, if indeed that is what is causing her decline.”

The orca, which was last seen Friday, is part of an endangered population that has dwindled to just 75 whales. Another female orca from the group that spends time in U.S. Northwest waters attracted global attention as the grieving animal tried to keep her dead baby afloat.

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.

For Marine Life, New Threats from a Fast-Tracked Canadian Pipeline

August 2, 2018 — Nearly everyone involved in the controversy over Canada’s troubled Trans Mountain Pipeline was surprised when Prime Minister Justin Trudeau announced in May that his government would take over the construction from a private company to ensure that additional tar sands crude oil can move from northern Alberta to a port in British Columbia.

The 715-mile Trans Mountain pipeline expansion would add a parallel pipeline to an existing one, increasing the route’s capacity from 300,000 to 890,000 barrels per day and helping producers sell crude and refined oil to Asian markets. Trudeau’s action means that a pipeline many thought might never be built is now on a fast track to completion by 2020. Construction is scheduled to begin this month.

The expansion of the Trans Mountain pipeline poses a range of environmental impacts and risks — from the possibility of leaks as the new line crosses hundreds of streams, rivers, and lakes across the breadth of the British Columbia wilderness, to the fact that it will allow Alberta’s massive tar sands reserves to be further exploited and contribute large amounts of CO2 to the atmosphere. But the most immediate and serious impacts may be to the marine environment along the coast of British Columbia, where the pipeline would terminate at the Westridge Marine Terminal at Burnaby near Vancouver.

The pipeline is expected to lead to a sharp increase in oil tanker traffic in the Salish Sea — a network of inland ocean waterways shared by British Columbia and Washington State — from four tankers a month to 34, along with associated construction and other ship  traffic. Marine biologists are especially concerned about the impact of increased ship noise on a highly endangered population of 75 killer whales, known as the “southern residents,” shared by the two countries.

Conservation groups launch lawsuit to establish ‘protection zone’ for endangered orcas

August 2, 2018 –Conservation groups are putting the feds on notice. The Center for Biological Diversity and Orca Relief Citizens’ Alliance on Wednesday sent a notice of intent to sue the Trump administration for failing to protect critically endangered orcas that live in the Pacific Northwest.

In November 2016, they petitioned the federal government to designate a “whale protection zone” in an area conservationists say is a critical to the population that has dropped to a 34-year low.

The latest move comes as heartbreaking images of J35, who has been carrying her dead orca calf for a week, highlight the struggles facing the critically endangered southern resident killer whales.

“What we are doing right now is just not working,” said Sarah Uhlemann with the Center for Biological Diversity.

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).
