Learning from gorillas to save killer whales

November 9, 2018 — In 2018, the southern resident killer whale population in the Pacific Northwest’s Salish Sea was at its lowest ever. The world watched in September as an orca named Scarlet, or J50, wasted away and died, leaving just 74 of her kind left. Some wondered if this was “What extinction looks like.”

Meanwhile, endangered mountain gorillas in Africa hit a milestone in the opposite direction. Their population climbed to more than 1,000—the highest in nearly a century.

Building on work begun by primatologist Dian Fossey of Gorillas in the Mist fame, Gorilla Doctors, a program led by the University of California, Davis, has been providing personalized veterinary care to these animals in the wild since the late 2000s. The gorillas have their own long-term health records, and the international team of veterinarians that observe and treat them know each one as they would their own family members and friends—down to the individual.

Judge rules EPA must protect salmon from rising water temperatures in Washington

October 29, 2018 — A U.S. Federal Court in Seattle, Washington, U.S.A. has issued a ruling that is intended to protect salmon and steelhead trout in the Columbia River basin from rising water temperatures.

In the mile-long lakes created by hydropower dams on the rivers, the water temperature has often exceeded 70 degrees Fahrenheit for days at a time, though the Clean Water Act bars the temperature in the river from exceeding 68 degrees. Cold water species such as sockeye and steelhead become stressed at temperatures over 68 degrees and stop migrating when the temperature exceeds 74 degrees.

The ruling instructs the Environmental Protection Agency to protect the species. The EPA will, within 60 days, come up with a “comprehensive plan to deal with dams’ impact on water temperature and salmon survival,” according to Columbia Riverkeeper Executive Director Brett VandenHeuvel, one of the plaintiffs of the case, which was initially filed in February 2017. Other conservation and fishermens’ groups were plaintiffs in the suit as well: Idaho Rivers United, Pacific Coast Federation of Fishermen’s Associations, Snake River Waterkeeper, and The Institute for Fisheries Resources.

Environmental groups sue U.S. Army Corps over Willamette dams, say salmon and steelhead at risk of extinction

March 14, 2018 — Three environmental groups followed through on a threat to sue the federal government Tuesday over the decline in wild salmon and steelhead in the Upper Willamette watershed.

The groups say the U.S. Army Corps of Engineers and National Marine Fisheries Service have failed to take required steps to improve conditions for the threatened fish.

The lawsuit targets the Willamette watershed’s system of dams and its negative impact on fish habitat.

“Federal dam operators in the Willamette River basin must act now to protect our native fish,” said Mark Sherwood, executive director of the Native Fish Society.

The lawsuit is derived from a legal agreement, called the Biological Opinion, issued in 2008, that essentially requires the Corps to modify dams to improve fish habitat.

Fishin’ Company leading MSC certification effort for Oregon’s Dungeness crab fishery

March 14, 2018 — An agreement between the Oregon Dungeness Crab Commission and The Fishin’ Company will pave the way for the Dungeness crab fishery in Oregon to seek Marine Stewardship Council certification.

The memorandum of agreement signed on 7 March will see The Fishin’ Company, a Munhall, Pennsylvania, U.S.A.-based  company that is a major buyer of the crab, provide financial resources and personnel to work alongside the fishery as it enters the MSC pre-assessment process.

“The Oregon Dungeness crab fishery is committed to a sustainable fishery through proven methods of management,” The Fishin’ Company Director of Sustainability Justin Baugh said. “They are focused on continuous improvement through science-based research and we believe the ODCC should be recognized for this and are excited to place our support behind them.”

West Coast Waters Returning to Normal; Some Fisheries Remain Disrupted

March 13, 2018 — SEAFOOD NEWS — Ocean conditions off most of the U.S. West Coast are returning roughly to average, after an extreme marine heat wave from about 2014 to 2016 disrupted the California Current Ecosystem and shifted many species beyond their traditional range, according to a new report from NOAA Fisheries’ two marine laboratories on the West Coast. Some warm waters remain off the Pacific Northwest, however.

The Southwest Fisheries Science Center and Northwest Fisheries Science Center presented their annual “California Current Ecosystem Status Report” to the Pacific Fishery Management Council at the Council’s meeting in Rohnert Park, Calif., on Friday, March 9. The California Current encompasses the entire West Coast marine ecosystem, and the report informs the Council about conditions and trends in the ecosystem that may affect marine species and fishing in the coming year.

“The report gives us an important glimpse at what the science is saying about the species and resources that we manage and rely on in terms of our West Coast economy,” Council Chairman Phil Anderson, of Westport, Wash., said in a press release. “The point is that we want to be as informed as we can be when we make decisions that affect those species, and this report helps us do that.”

Unusually warm ocean temperatures, referred to as “the Blob,” encompassed much of the West Coast beginning about 2014, combining with an especially strong El Nino pattern in 2015. The warm conditions have now waned, although some after-effects remain.

Warmer waters were blamed for increased growth of Pseudo nitzschia, which produces domoic acid. The domoic acid interrupted several fisheries, including Dungeness crab, rock crab and spiny lobster.

This Is Why You Don’t See People-Size Salmon Anymore

March 13, 2018 — While the orcas of Puget Sound are sliding toward extinction, orcas farther north have been expanding their numbers. Their burgeoning hunger for big fish may be causing the killer whales’ main prey, Chinook salmon, to shrink up and down the West Coast.

Chinook salmon are also known as kings: the biggest of all salmon. They used to grow so enormous that it’s hard to believe the old photos now. Fishermen stand next to Chinooks almost as tall as they are, sometimes weighing 100 pounds or more.

“This has been a season of unusually large fish, and many weighing from 60 to 70 pounds have been taken,” The Oregonian reported in 1895.

Now, more than a century later, “it’s not impossible that we see individuals of that size today, but it’s much, much rarer,” University of Washington research scientist Jan Ohlberger says.

Ohlberger has been tracking the downsizing of salmon in recent decades, but salmon have been shrinking in numbers and in size for a long time. A century’s worth of dam-building, overfishing, habitat loss and replacement by hatchery fish cut the size of the average Chinook in half, studies in the 1980s and 1990s found.

Dam-building and fishing have tailed off, but Chinooks have been shrinking even faster in the past 15 years, according to a new paper by Ohlberger and colleagues in the journal Fish and Fisheries. Older and bigger fish are mostly gone.

NOAA is pro-aquaculture, but won’t weigh in on salmon farm ban

March 13, 2018 — BOSTON — Don’t look for the US National Oceanic and Atmospheric Administration (NOAA) to challenge the recent decision by Washington state to end salmon farming off its coast. The federal government’s hands are tied, said a senior NOAA official at the Seafood Expo North America, in Boston, Massachusetts, on Sunday afternoon.

“We do have separation of powers in the United States between the federal government and the state government,” said Michael Rubino, NOAA’s director of aquaculture, when asked. “And this was largely a state government matter.”

Washington state governor Jay Inslee is expected to soon sign House Bill 2957, a bill passed by the state’s Senate, 31-16, on March 2 that would allow the leases for offshore aquaculture facilities there to expire by 2025. The state’s House voted roughly two weeks earlier to support the bill.

Washington state’s dramatic action followed the much-publicized escape, in August, of more than 250,000 Atlantic salmon from a Cooke Aquaculture facility near Cypress Island.

When asked if NOAA might weigh in, Rubino simply responded that NOAA doesn’t have a say in the matter.

Cooke Aquaculture continuing to fight Washington ban even as it ponders next steps

March 9, 2018 — In an interview with SeafoodSource, Cooke Vice President of Communications Joel Richardson discussed his company’s efforts to convince Washington Governor Jay Inslee of the merits of the industry as the governor considers signing a bill that would phase out non-native finfish aquaculture in his state. Richardson also discussed the formulation of his company’s back-up plan in case it was unsuccessful in convincing the governor to veto the bill.

SeafoodSource: Is Cooke making any efforts to reach out to Gov. Inslee as he considers signing the bill?

Richardson: Yes, we will continue to reach out to Gov. Inslee over the coming days to urge him to veto HB 2957. Over the last few months we have provided Gov. Inslee and all legislators in Washington with evidence-based science from well-respected, credible fishery scientists to inform and educate on sea farming practices.  We are also aware that the Washington Fish Growers Association is now urging Governor Jay Inslee to veto the bill this week calling on a ban on Atlantic salmon aquaculture in state waters “Ill-conceived and politically motivated rather than based on the best available science.”

SeafoodSource: In what ways was science not taken into proper account by legislators as they considered the bill?

Richardson: You will have to ask the governor and legislators to answer that question.  However, in the aquaculture industry’s view, it’s appalling that that lawmakers have ignored calls to drop the ban from some of the world’s top aquaculture and fisheries scientists, including from the state Department of Fisheries and Wildlife, who refuted false and misleading claims made by anti-sea farming groups, tribes, and politicians that Atlantic salmon, when and if they escape, could interbreed with Pacific stocks or colonize rivers. Nothing could be further from the truth. The fact is that the science from decades of peer-reviewed research does not support the conspiracy theory that Atlantic salmon that escape from net pens will colonize our rivers and/or interbreed with native stocks.

Scientists Send Letter to Washington Legislature Urging Delay on Legislation to Ban Net Pens

March 1, 2018 — SEAFOOD NEWS — Four prominent scientists have sent a letter to the Washington State Legislature urging them to stop House Bill 2957, which “would essentially halt Atlantic salmon aquaculture in this state forever.”

The scientists include the former 40-year director of the Manchester, Washington, laboratory; two former directors of the national aquaculture program run by NOAA; a former Director of the Northwest Fisheries Science Center; and the former president of Stolt Sea Farms Washington, Inc.

“We call on our esteemed elected representatives to delay any decisions regarding the future of salmon farming in Washington until the scientific community, represented in this state by some of the world’s leading aquaculture and fisheries scientists and researchers in the fields of fish culture, genetics, nutrition, and fish behavior, has had an opportunity to present science in a clear and objective light—rather than in a climate fueled by fear and propaganda,” the letter states.

The authors offer to present research that responds to the legislature’s fears on four areas of concern for Atlantic salmon farms in the event of a pen failure or escape.

Interbreeding — the authors point out that interbreeding has been encouraged in a scientific setting, and all attempts for the past f40 years have been unsuccessful.

Competition for food — Peer-reviewed studies have shown convincingly that “captive” or pen-reared salmon have not learned how to “hunt” for food, simply because they are used to being fed on a regular timetable.

Competition for habitat —  Scientists to date have found no evidence of Atlantic salmon spawning on the West Coast of North America.

Disease transmission — the authors say “No example of disease transfer from farmed salmon to wild fish has ever been documented by any regulatory agency in the state of Washington.”

Finally, they strongly urge legislators to not “throw out the baby with the bathwater”—salmon farming—that is now producing millions of metric tons of nutritious salmon, worth billions of dollars, around the world.

The letter is signed by Linda Chaves, former Senior Advisory on Seafood and Industry Issues; Dr. John Forster, former president of Stolt Sea Farm; Dr. Robert Iwamoto, director of the office, management, and information at the Northwest Fisheries Science Center, NOAA; and Dr. Conrad Mahnken, former NOAA National Aquaculture Coordinator, director of the NOAA Manchester Laboratory, and Washington Fish and Wildlife Commissioner.

California sea lion population rebounds

January 24, 2018 — California sea lions are doing just fine. Thanks for asking.

More than fine, actually.

Sea lions have fully rebounded with an estimated population of more than 250,000 in 2014, according to a recent study by scientists with the National Oceanic and Atmospheric Administration. In 1975, the population was estimated at less than 90,000.

The study reconstructed the population’s triumphs and trials over the past 40 years.

“The population has basically come into balance with its environment,” co-author Sharon Melin, a research biologist at the Alaska Fisheries Science Center, said in a statement. “The marine environment is always changing, and their population is at a point where it responds very quickly to changes in the environment.”

NOAA’s declaration that California sea lions have fully rebounded does not mean a “delisting” as it would if the sea lion was listed as threatened or endangered under the federal Endangered Species Act.

“Although there is no provision in the Marine Mammal Protection Act (which protects sea lions) to delist a species, there is a provision that allows states to ask NOAA Fisheries to take over management of species that have reached carrying capacity (in the law it is called Optimum Sustainable Population or OSP) and potentially do more to control their numbers,” wrote NOAA spokesperson Michael Milstein when announcing the report’s findings.

The goal now, Melin said, is to keep the population balanced between 183,000 and 275,000 individuals.

The rebound is a victory for the federal Marine Mammal Protection Act. But as in other instances of animal populations beating the odds — wolves, for example — it’s a success story that comes with challenges.

As the California sea lion population has grown, the animals have expanded their range, bringing them into conflict with humans and endangered fish.

Where you sit’

In Astoria, male California sea lions have taken over an entire stretch of docks at the Port of Astoria’s East Mooring Basin. Port employees have attempted numerous deterrent tactics over the years, everything from fluttering wind dancers to a fake killer whale. Nothing has really worked.

Upward of 1,000 pinnipeds were recorded in a single daily count at the mooring basin in 2015. While fewer sea lions returned this spring, plenty showed up in the fall and many have stuck around through the winter instead of leaving like they have in the past, said Janice Burk, marina manager.

The port plans to install more low railing fabricated by students from Knappa along the docks in the spring. It has proved to be the one deterrent that seems to work. Sometimes.
