Washington’s fishing fleet due for a big makeover

November 18, 2016 — The fishing fleet in Washington State is getting older, and it’s due for a big upgrade. A new study says that work could bring in billions of dollars for the state. That could help save the region’s struggling shipyards.

But first you’ll have to convince the old fishermen to spend money on their boats.

It’s hard to be a shipyard in Seattle. There’s a lot of competition for the land they’re sitting on. “There was a bunch of other smaller yards around here, and they’ve gone away” said Scott Woodard. He works at Pacific Fishermen Shipyard in Ballard.

He fell in love with working on old boats. He mastered an ancient technique where you push strings of tarred hemp into the seams between planks on a wooden boat.

“This is caulking,” he explained. “But people will say corking. My mentor was kind of a traditionalist. And he called himself a caulker. So in honor of him, that’s what I say. I’m a caulker, not a corker.”

But it’s not caulking or corking that pays the bills at this shipyard. Most fishing boats are metal. The real money is in fixing up those boats, doing things like painting and sandblasting.

Conservation groups petition President Obama to create ‘safe zone’ for orcas

November 7, 2016 — SEATTLE — Conservative groups from the Pacific Northwest petitioned President Obama on Friday in an effort to protect the Puget Sound orcas.

The Orca Relief Citizen’s Alliance and Project Seawolf want the Obama administration to create a ten square mile “whale protection zone” near San Juan Island.

The groups claim the noise and pollution from boats and other human disturbances interfere with the orcas’ feeding.

Warm Pacific Ocean ‘blob’ facilitated vast toxic algae bloom

September 30, 2016 –SEATTLE — A new study finds that unusually warm Pacific Ocean temperatures helped cause a massive bloom of toxic algae last year that closed lucrative fisheries from California to British Columbia and disrupted marine life from seabirds to sea lions.

Scientists linked the large patch of warm ocean water, nicknamed the “blob,” to the vast ribbon of toxic algae that flourished in 2015 and produced record-breaking levels of a neurotoxin that is harmful to people, fish and marine life.

The outbreak of the toxin domoic acid, the largest ever recorded on the West Coast, closed razor clam seasons in Washington and Oregon and delayed lucrative Dungeness crab fisheries along the coast. High levels were also detected in many stranded marine mammals.

“We’re not surprised now having looked at the data, but our study is the first to demonstrate that linkage,” said Ryan McCabe, lead author and a research scientist at the University of Washington’s Joint Institute for the Study of the Atmosphere and Ocean. “It’s the first question that everyone was asking.”

Studies Focus on Acidic Ocean Impact on Dungeness Crabs

September 23, 2016 — Millions of pounds of Dungeness crab are pulled from Pacific Northwest waters each year in a more than century-old ritual for commercial and recreational fishermen.

But as marine waters absorb more carbon dioxide in the atmosphere, federal scientists are worried that the ocean’s changing chemistry may threaten the sweet-flavored crustaceans.

So scientists with the NOAA Fisheries’ Northwest Fisheries Science Center are exposing tiny crab larvae to acidic seawater in laboratory experiments to understand how ocean acidification might affect one of the West Coast’s most lucrative fisheries.

Research published this year found that Dungeness crab eggs and larvae collected from Puget Sound and exposed to higher levels of carbon dioxide — which increases ocean acidity — grew more slowly and larvae were more likely to die than those in less corrosive seawater.

Now, researchers are taking the experiments a step further to study how the crabs respond to multiple stressors during various growth stages. They also plan to analyze the sublethal effects: Even if the crabs don’t die, are they affected in physiological or other ways by ocean acidification?

“They’re so economically and ecologically important here on the West Coast,” said Paul McElhany, a research ecologist with the Northwest Fisheries Science Center north of Seattle, who is leading the current experiments.

Crab larvae are valuable food for small salmon and forage fish like herring that are eaten by salmon. Dungeness crabs are also the top revenue-fetching fishery in Washington and Oregon. In 2014, nearly $200 million worth of crabs were harvested along the West Coast.

Seattle company debuts high-tech, sustainable fishing vessel

September 7, 2016 — SEATTLE — A new commercial fishing vessel, built in Washington, is charting new territory for sustainability and crew safety.

The F/V Blue North is a 191 foot freezer longliner owned by Seattle based Blue North Fisheries. The vessel was designed in Norway and built by Dakota Creek Industries in Anacortes.

“I’m kind of pinching myself – we are finally here – we’ve got it,” said Patrick Burns who is the co-founder of Blue North. “It’s a state of the art vessel.”

The $36 million fishing boat has been under construction for several years. It was delivered last week and has been receiving some final touches at Seattle’s Pier 91 as it prepares to make fishing history in Alaska’s Bering Sea.

“This vessel is a game changer – it’s the greenest, most sustainable and highest tech commercial fishing vessel that’s ever been built in the United State and possibly the world,” said Kenny Down, President and CEO of Blue North Fisheries.

There is no other vessel like it in the Alaska hook and line cod fishery.

Rarely seen Arctic seal spotted in Washington State – 2,000 miles from home

August 19, 2016 — A rarely seen pinniped that inhabits sub-Arctic and Arctic waters – from the Bering Sea north to the Chukchi Sea – has been spotted 2,000 miles from home, on a beach in Washington state.

Biologists spotted a single ribbon seal hauled out on Long Beach Peninsula on Tuesday, and captured a few images before the seal returned to the water.

The extraordinary sighting marks the second time in four years that a ribbon seal has appeared so far south of its typical range. The other was 2012, when a ribbon seal was spotted twice in the Seattle area.

After that sighting, Peter Boveng, leader of the polar ecosystem program with the National Marine Fisheries Service, told the Associated Press, “There are not many people who see these regularly.”

Coral reefs need fish urine to thrive

August 17, 2016 — SEATTLE — Coral reefs offer many fish species camouflage and a variety of nooks and crannies in which to hide. In return, fish offer their urine.

It’s not exactly a symbiotic relationship, but it’s a pretty good deal for both parties. When they pee, fish release phosphorous, a vital nutrient. They also excrete nitrogen in the form of ammonium through their gills, another important food for coral.

New research suggests a lack of fish pee explains the lack of nutrients surrounding coral in waters where commercial fishing is common.

The research was published this week in the journal Nature Communications.

“Part of the reason coral reefs work is because animals play a big role in moving nutrients around,” lead study author Jacob Allgeier, a postdoctoral researcher at the University of Washington’s School of Aquatic and Fishery Sciences, explained in a news release.

“Fish hold a large proportion, if not most of the nutrients in a coral reef in their tissue, and they’re also in charge of recycling them,” Allgeier said. “If you take the big fish out, you’re removing all of those nutrients from the ecosystem.”

From ‘The Water’s Edge To The Cutting Edge’: Fish Skeletons, CT Scans And Engineering

August 1, 2016 — Adam Summers used to trade Snickers bars to get free CT scans of dead fish.

He likes fish. A lot.

Summers is a professor at the University of Washington in the biology department and School of Aquatic and Fisheries Sciences.

“I’ve always been a fish guy,” he says. “It’s just been in my blood since I was as small as I can remember.” Summers was a scientific consultant on Finding Nemo and did similar work with Finding Dory.

He describes himself as a biomechanist — he studies “how physics and engineering govern some parts of biology.” Some of that refers to, for example, studying how humans could use ideas from the structure of a fish skeleton to design an underwater vehicle.

“A lot of what I do is in the realm of what’s called biomimetics,” Summers tells NPR. “I’m looking to the sea for inspiration, for biomimetics solutions to technical problems.”

He’s based on an island about 60 miles north of Seattle, at the University of Washington’s Friday Harbor Laboratories. The lab is only a short walk from the water — from “the water’s edge to the cutting edge,” Summers says. As part of his work at the lab, his team is trying to make 3-D CT scans of all 33,000 varieties of fish.

So, why?

Researchers like Summers want to understand how fish work. To do that, he says, “one of the very, very useful things is to understand exactly what the skeleton looks like. It is shockingly complex. Your skull is just a few bones. Fish skulls are dozens and dozens of bones.”

That’s where the CT scans come in. The machines are usually used to see the insides of humans. Many years ago, Summers wanted to see the insides of fish.

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.
