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.”

LSU researcher, a modern-day explorer, travels to remote parts of world to discover new fish species

September 21, 2016 — Prosanta Chakrabarty travels the world searching for fish that few humans have ever seen.

The LSU researcher wants to learn what these underwater unknowns can teach about evolution and the history of the earth.

He’s a modern-day explorer, swimming through murky waters and diving into caves in search of seldom-seen species.

“It’s such a wonderful job. It’s a great experience to be having,” he said. “Fish let me do that. They let me go to these weird places and discover them in odd areas of the world that most people don’t get to go to.”

And Chakrabarty, 37, uses his adventures — along with his natural ability to captivate an audience — to teach the world about science.

Speaking at the prestigious TED conference in Vancouver, British Columbia, earlier this year, Chakrabarty told an audience that ichthyology — the study of fish — is the only science with YOLO in the name.

“Now, to the cool kids in the audience, you already know,” he said. “YOLO stands for ‘you only live once.’ And because I only have one life, I’m going to spend it doing what I always dreamed of doing — seeing the hidden wonders of the world and discovering new species. And that’s what I get to do.”

Born in Montreal, Quebec — where his family lived after immigrating from India — Chakrabarty grew up in Queens, New York.

“Not the kind of place you would expect for someone who loves nature,” Chakrabarty said. “I think I went fishing once in some dirty pond catching sunfish.”

Why a Single Crab Has West Coast Researchers Worried

September 8, 2016 — Invasive European green crabs have been swarming up and down both coasts, but because of the flow of ocean currents around the Pacific Northwest, inland waters of BC and Washington State were thought to be relatively safe. Well, on Sept. 2, volunteers announced they’d recently caught a single crab on San Juan Island, in Puget Sound. Although it’s just one for now—and it could have hitched a ride on someone’s fishing gear, or another way—it’s the first confirmed sighting in these inland waters.

Starting next week, a “rapid response team” will be out laying traps and trying to figure out if there are more crabs out there. The aliens pose a threat to the region’s native species.

“I’ll admit, I have a lot of respect for these crabs,” Sean McDonald, a research scientist at the University of Washington, told me. McDonald works with the Washington Sea Grant’s Crab Team, a network of citizen scientists that serves as an early alert for the crustacean’s encroachment. They caught the crab, and will be organizing next week’s response. “They’re tough and resilient,” he continued. “They make a living anywhere they can.”

Strong halibut catches in Alaska leading to higher quotas

July 1, 2016 — After years of slashed quotas, the Alaskan halibut fishery is enjoying a second year of growth in 2016.

The 2016 quota share commercial halibut fisheries opened on 19 March with a fleet-wide quota of 18.16 million pounds. The quota is up from 17.93 million pounds in 2015 and 16.75 million pounds in 2014.

Quota improvements have also been seen in British Columbia, Canada. The 2016 B.C. quota is 6.20 million pounds up from 5.91 million pounds in 2015 and 5.79 million pounds in 2014.

“We’ve been on a bit of decrease since the peak of the halibut stock abundance in the late 1990s, but last year [2015] saw the first year of an increase in quite a number of years,” said Bruce Leaman, the executive director of the International Pacific Halibut Commission, the public international organization responsible for managing the fisheries.

IPHC released its latest landing report on 21 June, 2016, and to that date, catch rates have been similar to last year. Alaskan fishermen have landed 8.8 million pounds of halibut, or 48 percent of the 2016 commercial fishery catch limit. At this same date last year 8.8 million pounds had been harvested, representing 49 percent of the 2015 catch limit.

“[The fishing is] about on par with what we’ve seen other years in terms of how quickly the quota is being caught,” Leaman said.

He went on to predict a lull in halibut landings during the summer as many vessels leave off halibut fishing to pursue salmon and other species caught during shorter management periods.

Alaska asks John Kerry to raise B.C. mine pollution concerns with Canada

May 16, 2016 — VANCOUVER, British Columbia — British Columbia’s downstream neighbours in Alaska have long been concerned about mining pollution flowing across the border.

Now that B.C.’s Auditor-General has confirmed that those fears are well founded, issuing an audit recently that found the province is doing a poor job of regulating its mines, three Alaskan politicians have elevated the issue in Washington.

In a letter sent on Thursday, Senators Lisa Murkowski and Dan Sullivan, and Congressman Don Young, urged U.S. Secretary of State John Kerry to talk about it with the Canadian government.

“We write to express our continuing concerns about the development of several hardrock mines in British Columbia and their potential effects on water quality in the transboundary rivers that flow from Canada into southeast Alaska,” the letter states.

The Alaskans told Mr. Kerry that he should “utilize all measures at your disposal to address this issue at the international level.”

Warming Oceans Are Turning Sea Stars to Goo and Killing Lobsters, Scientists Say

February 17, 2016 — Warming waters in the Atlantic and Pacific oceans have increased the prevalence of diseases that are turning sea stars to mush and killing lobsters by burrowing under their shells and causing lesions, two new studies say. The outbreaks are so lethal, according to a biologist involved in both studies, that at least one species of sea star has vanished off the coasts of Washington and British Columbia and the lobster fishery, already decimated in southern New England, will likely be threatened in Maine.

In the Pacific, a wasting disease is blamed for the disappearance of the technicolor sunflower sea star. It’s also laying waste to the ochre sea star that scientists at Cornell University, the University of Puget Sound and Northeastern University, as well as other institutions, examined for the latest research. Their reports were published this week.

Numerous climate studies have shown that the oceans are warming. In addition, 30 percent of the carbon released into the atmosphere ends up there, leading to acidification that’s further destroying coral, shell life and other organisms.

The sea-star study was led by Morgan E. Eisenlord, an evolutionary biologist at Cornell, and published in the Proceedings of the Royal Society B. Both in a laboratory and at 16 sites on the San Juan Islands off Washington’s coast, researchers determined that ochre sea stars gradually became sicker as water temperatures rose slightly. Conditions simulated in the lab confirmed what the scientists observed in the field.  As temperatures rose, the disease became more prevalent, and adult ochres died within days. The disease, plus death, was more prominent in temperatures between 54 degrees and 66 degrees Fahrenheit. For the adults, the risk of death was 18 percent higher at 66 degrees.

Studies aim to restore habitat of imperiled Northwest fish

February 8, 2016 — BOISE, Idaho (AP) — Scientists in the Pacific Northwest are studying more than a dozen watersheds to develop templates on habitat restoration that could be used in similar streams to bolster struggling fish populations.

The federal government lists 28 populations of salmon and steelhead on the West Coast that need protections due to low numbers despite spending millions of dollars every year on restoration efforts.

 The studies aim to make those efforts more successful. They focus on 17 watersheds in Washington, Oregon, Idaho, Northern California and British Columbia and examine the benefit of everything from dam removal to building artificial beaver dams in tributaries.

Creating templates for habitat restoration could save time and money by using strategies known to produce good results in similar habitats in the region, said George Pess, a research fisheries biologist for the National Oceanic and Atmospheric Administration.

“The overall goal is to learn enough to be smart about our restoration,” he said, noting that the studies will offer recommendations to private, tribal and government entities but won’t produce any legally binding regulations.

A Canadian Threat to Alaskan Fishing

January 23, 2016 — SITKA, Alaska — From fall through spring, the fleet of commercial fishing boats here in the panhandle of Alaska stalk winter king salmon. In the mornings prisms of ice sparkle beneath the sodium lights of the docks, where I live on a World War II tugboat with my wife and 8-month-old daughter. This winter I’ve been out a few times fishing on the I Gotta, catching pristine wild salmon, torpedoes of muscle. But the work is slow, five fish a day, and my skipper recently traveled down to Reno, Nev., for knee surgery.

Carpeted in rain forest and braided with waterways, southeast Alaska is among the largest wild salmon producers in the world, its tourism and salmon fishing industries grossing about $2 billion a year. But today, the rivers and the salmon that create these jobs — and this particular way of life, which attracted me from Philadelphia to Sitka almost 20 years ago — are threatened by Canada’s growing mining industry along the mountainous Alaska-British Columbia border, about a hundred miles east of where I now write.

At least 10 underground and open-pit copper and gold mining projects in British Columbia are up and running, in advanced exploration or in review to be approved. These operations generate billions of tons of toxic mine tailings stored behind massive dams, creating an ecological hazard at the headwaters of Alaska’s major salmon rivers — the Stikine, Unuk and Taku, which straddle the border with Canada.

Despite being subjected to the environmental and health risks of these upstream mining projects, Alaskans have no say in their approval. Which is why fishermen, Alaska native tribes, local municipalities, tourism businesses, our congressional delegation and thousands of individual Alaska residents have been clamoring for the State Department to refer this issue to the International Joint Commission, an American and Canadian advisory body established in 1909 to ensure that neither country pollutes the waters of the other.

Shellfish Farmers Fear Ocean Acidification May Affect Harvests in 2016

January 8, 2016 — Ocean acidification was blamed for the shutdown of the Washington oyster fishery last year and B.C. could be next, partially for the same reason, said Rob Saunders, owner of Island Scallops at Qualicum Beach.

Speaking to TheProvince, Mr Saunders said that Island Scallops, which provides seed oysters and scallops for farmers, lost 90 per cent of its oyster larvae last year.

Acidic water affects the oysters’ ability to grow a hard shell. It takes two years for oysters to mature for harvest, and Mr Saunders said oysters may be in short supply this year.

Protesters threaten to renew blockade in B.C. fish farm dispute

September 21, 2015 — Protesters who had been attempting to block a fish farm on Vancouver Island say they will return to their camp unless the Norwegian company behind the site removes its docks and equipment, as protesters had expected.

Protesters who call themselves the Yaakswiis Warriors said representatives from Cermaq, an aquaculture company with operations in Canada, Chile and Norway, recently promised to remove the installation at a site near Ahousaht, B.C., on Monday morning. A small group of opponents had been blockading the site, located north of Tofino, since Sept. 9, citing potential environmental damage that could result from the plant.

But while Cermaq vessels were nearby, nothing was moved, even though protesters who had previously blockaded the site and their supporters waited several hours in the hopes of seeing some activity.

“About 15 of us went out on four boats this morning just before first light, about 6 a.m. and we waited out there for near six hours,” said Sacheen Seitcham, a spokeswoman for the protesters. “They were about 10 minutes away… the barge was there, with the crane on it, and the tugboat was there.”
