University of Washington scientist launches effort to digitize all fish

July 27, 2016 — SEATTLE — University of Washington biology professor Adam Summers no longer has to coax hospital staff to use their CT scanners so he can visualize the inner structures of stingray and other fish.

Last fall, he installed a small computed tomography, or CT, scanner at the UW’s Friday Harbor Laboratories on San Juan Island in Washington state and launched an ambitious project to scan and digitize all of more than 25,000 species in the world.

The idea is to have one clearinghouse of CT scan data freely available to researchers anywhere to analyze the morphology, or structure, of particular species.

So far, he and others have digitized images of more than 500 species, from poachers to sculpins, from museum collections around the globe. He plans to add thousands more and has invited other scientists to use the CT scanner, or add their own scans to the open-access database.

“We have folks coming from all over the world to use this machine,” said Summers, who advised Pixar on how fish move for its hit animated films “Finding Nemo” and “Finding Dory” and is dubbed “fabulous fish guy” on the credits for “Nemo.”

He raised $340,000 to buy the CT scanner in November. Like those used in hospitals, the CT scanner takes X-ray images from various angles and combines them to create three-dimensional images of the fish.

With each CT scan he posted to the Open Science Framework, a sharing website, people would ask him, “What are you going to scan next?” He would respond: “I want to scan them all. I want to scan all fish.”

NOAA: Dungeness crab in peril from acidification

May 19, 2016 — The Dungeness crab fishery could decline West Coastwide, a new study has found, threatening a fishing industry worth nearly a quarter-billion dollars a year.

Scientists at the Northwest Fisheries Science Center in Seattle found that pH levels likely in West Coast waters by 2100 at current rates of greenhouse-gas pollution would hurt the survivability of crab larvae.

Increasing ocean acidification is predicted to harm a wide range of sea life unable to properly form calcium carbonate shells as the pH drops. Now scientists at the NOAA’s Northwest Fishery Science Center of Seattle also have learned that animals with chitin shells — specifically Dungeness crabs — are affected, because the change in water chemistry affects their metabolism.

Carbon dioxide, a potent greenhouse gas, is pumped into the atmosphere primarily by the burning of fossil fuels. Levels of atmospheric C02 have been steadily rising since the Industrial Revolution in 1750 and today are higher than at any time in the past 800,000 years — and predicted to go higher.

When carbon dioxide mixes with ocean water it lowers the pH. By simulating the conditions in tanks of seawater at pH levels likely to occur in West Coast waters with rising greenhouse gas pollution, scientists were able to detect both a slower hatch of crab larvae, and poorer survival by the year 2100.

Puget Sound Crisis Brings Salmon Fishing Closure

April 29, 2016 — SEATTLE — All salmon fishing in Puget Sound will close on May 1 unless federal officials issue last-minute permits.

State and tribal fisheries managers failed to reach an agreement Wednesday for this year’s Puget Sound fishing season, which runs from May 1 to April 30, 2017.

“We had one last round of negotiations in hopes of ensuring salmon seasons in Puget Sound this year,” Washington Department of Fish and Wildlife Director Jim Unsworth said in a statement. “Regrettably, we could not agree on fisheries that were acceptable to both parties.”

Washington Salmon Run Called ‘Disastrous’

April 20, 2016 — SEATTLE — Fisheries managers on Friday approved limited ocean salmon fishing off the Washington coast, but are still discussing plans for Puget Sound, including closing all fishing in the region due to disastrous runs.

The Pacific Fishery Management Council, which includes state and tribal officials, met last week in Vancouver, Wash. to set commercial and recreational fishing guidelines.

The president of the Puget Sound Anglers called predictions for this year’s salmon run “the worst we probably have ever seen.”

The council set an ocean-salmon sport catch at 35,000 Chinook and 18,900 hatchery coho salmon.

Debate continues this week on what, if any catch, will be allowed in Puget Sound.

ALASKA: Gulf fishermen wary of Congressional intrusion into council process

April 7, 2016 — Gulf of Alaska fishermen suspect that Washington, D.C., politics might come into play for fisheries regulations they want left to the North Pacific Fishery Management Council.

A letter circulated by the Alaska Marine Conservation Council and signed by 250 Gulf of Alaska fishermen and residents was sent to each of Alaska’s three congressional delegation members.

The letter asks that the Alaska’s representatives in the nation’s capital oppose any legislation intended to press Gulf of Alaska fisheries regulations.

“Specifically, we request our Alaska delegation to support development of a Gulf of Alaska Trawl Bycatch Management Program (aka catch share) in the Council process so all stakeholders may contribute to a transparent process,” the letter asks.

“Please do not support any attempt to circumvent the council process through legislation in Washington, D.C., as that would effectively preclude Alaskan coastal communities and stakeholders from having a direct voice in the process.”

During ComFish, an annual Kodiak commercial fisheries booster event, Stephen Taufen of Groundswell Fisheries Movement acknowledged writing the letter and said that the Congresswoman in question is Rep. Jaime Hererra Beutler, R-Wash.

Beutler, a representative of southwest Washington, sits on the House Appropriations Committee. Much of the Gulf trawl industry is based in Seattle.
