Devastating Collapse of Groundfish Fishery Forces a More Sustainable Future

October 9, 2019 — The following was released by NOAA Fisheries:

The groundfish fishery closures in 2002 were sweeping. Hundreds of thousands of square miles of West Coast waters shut off to the very same bottom fishing that had many fishing ports booming in the previous decade. The Secretary of Commerce declared the 2000 groundfish fishery a failure, with losses to fishermen estimated at $11 million.

The rockfish boom was going bust.

“Behind the sweeping action is a reluctant realization that the vast ocean has limits and cannot, as was long believed, provide an inexhaustible supply of fish,” the Los Angeles Times said in announcing the closures that in effect created the largest marine reserve ever off the West Coast. The closures covered most of the continental shelf, home to nearly 100 different species of rockfish.

Scientists estimated that some of those fish could take nearly a century to rebuild.

“It was devastating,” said Jason Cope, a research fish biologist at NOAA Fisheries’ Northwest Fisheries Science Center in Seattle who worked on teams assessing the decline of groundfish. “It radically altered people’s expectations of their livelihood. Suddenly a future they thought was reliable turned out to be anything but.”

West Coast Rockfish Boom with the Blob

October 4, 2019 — The following was released by NOAA Fisheries:

The high temperatures that came with the marine heatwave known as the Blob led to unprecedented mixing of local and subtropical species. There were, often with new and unpredictable outcomes. Out of that mix came one unexpected winner: West Coast rockfish. These bottom-dwelling species, which that had previously collapsed in the face of overfishing during the 2000s, thrived under the new conditions.

Scientists from Oregon State University and NOAA Fisheries’ Northwest Fisheries Science Center recount the boom in young rockfish in a new research paper in the journal Fisheries. It examines the effects of the Blob as documented by NOAA Fisheries offshore surveys. Scientists have been conducting the surveys for more than 20 years. The Blob years brought some of the most dramatic changes in marine life off the West Coast they’ve ever seen.

Unexpected interactions may have also altered the abundance of some species, from plankton that support the food web to fish that depend on them, the researchers wrote.

In the waning months of the Blob in 2016, juvenile rockfish increased over a large area from California to Alaska. Since juvenile rockfish are very difficult to distinguish from one another, scientists could not tell which species benefited. They could not tell what specifically drove the boom in their numbers and or whether they will support fisheries in future years.

Jamestown S’Klallam Tribe partnering with Cooke Aquaculture Pacific for Northwest native species farm

October 3, 2019 — The following was released by the Jamestown S’Klallam Tribe:

The Jamestown S’Klallam Tribe is pleased to announce a joint venture with Cooke Aquaculture Pacific.

The joint venture will initially work to rear sablefish (black cod) and sterile triploid, all-female rainbow trout. The venture will require reinstatement of the farm lease at Port Angeles, in exchange for significant investment by the venture in new infrastructure and local jobs in the area. The two partners will work together to rear these Northwest native species in Port Angeles Harbor.

“Our Council is committed to pursuing our self-reliance goal through diversified economic development and education, and we believe this partnership with Cooke Aquaculture Pacific will contribute to meeting that goal,” says Jamestown S’Klallam Tribe Chairman/CEO W. Ron Allen. “We, along with our sister tribes, are strong stewards of our environment. And we firmly believe we can implement net pen aquaculture consistent with our tribal heritage and cultural values. By working together, combining our history and experience fishing on the Olympic Peninsula with Cooke’s experience and expertise in aquaculture, we are confident that we can raise a sustainable supply of trout and sablefish and contribute to our local economy.”

This partnership with Cooke augments the well-established working relationship between the Tribe, National Oceanic and Atmospheric Administration’s (NOAA’s) Northwest Fisheries Science Center, Manchester Research Laboratory and the University of Washington, who have worked together since 2015 on black cod aquaculture research.

The Jamestown S’Klallam Tribe is the second largest employer in Clallam County, providing jobs for over 750 people in its Tribal government and businesses. In addition to the businesses that provide revenues for Tribal programs and services, the Tribe is an active partner in many community projects focusing on protection and restoration of natural resources and habitat, improving health and wellness for the Olympic Peninsula, public safety, and promoting quality education.

“The Jamestown S’Klallam Tribe is known for being progressive and forward-thinking in its approach to resource management and economic development,” says Glenn Cooke, CEO of Cooke Aquaculture Pacific. “We look forward to working together to produce top quality seafood for consumers in Washington and across the US.” The partners are expecting to start up the operations in the fall of 2019.

Study: Fishery consolidation in Alaska leaves fishermen vulnerable

May 9, 2019 — Alaskan commercial fishermen are specializing more and more, leaving them more vulnerable to the immense uncertainty fishermen have to contend with, according to a new study.

Targeting a diverse array of fish types in different regions can allow fishermen to weather the ups and downs instigated by fish population changes, new regulations, deflating markets and environmental disasters. But fishermen in Alaska are increasingly specializing. Fewer fishermen are on the water than three decades ago, and those who remain are participating in fewer fisheries, according to the study, which was published in Fish and Fisheries.

“Across different fisheries and regions of Alaska, there are fewer people fishing than there used to be and their fishing portfolios have become less diverse,” Anne Beaudreau, the lead author of the study and an associate professor at the University of Alaska Fairbanks, told SeafoodSource.

Individual fishery quota systems, plus the high cost of permits and other institutional barriers, have made it more difficult for new players to enter Alaskan fisheries, according to the study.

Though fishermen could, in theory, diversify their portfolio of permits, those management restrictions and high costs often prevent them from doing so, leading to more specialization. Permits can cost hundreds of thousands of dollars depending on the fishery, Beaudreau said.

Research expedition reports surprising findings on coho, sockeye salmon in Pacific Ocean

March 28, 2019 — After five weeks at sea, a team of 21 scientists from five countries returned Monday with some surprising findings about the mysterious lives of salmon in the Pacific Ocean, according to Laurie Weitkamp, a salmon biologist with NOAA’s Northwest Fisheries Science Center in Newport, Oregon.

“It was quite an experience,” said Weitkamp, one of three chief scientists aboard the Russian research vessel Professor Kaganovsky.

The expedition was part of activities associated with the International Year of the Salmon and was meant to look at how salmon fare in the open ocean. Among the surprises that emerged from the cruise was the relatively small number of pink salmon. Pinks, the most abundant salmon in the Pacific Ocean, normally make up about half of all the salmon in the region. Yet during the expedition — which covered some 345,000 square miles — pink salmon made up only about 10 percent of the salmon caught in the researchers’ nets.

“We kept asking, ‘Where are the pinks? Why aren’t you here?’” Weitkamp recalled.

Decline of salmon adds to the struggle of Puget Sound’s orcas

February 26, 2019 — The crew of the Bell M. Shimada hauled in the net, long as a football field and teeming with life. Scientists, off the coast of Washington for a week on this June research trip, crowded in for a look.

Each tow of the net revealed a changing world for chinook salmon, the Pacific Northwest’s most famous fish — and the most important prey for the southern-resident killer whales that frequent Puget Sound.

There were salmon the scientists expected, although fewer of them. But weirdly also pompano, tropical fish with pretty pink highlights, iridescent as a soap bubble, that were not supposed to be there at all.

What the scientists see each year on this survey underway since 1998 has taken on new importance as oceans warm in the era of climate change.

Decadelong cycles of more and less productive ocean conditions for salmon and other sea life are breaking down. The cycles of change are quicker. Novel conditions in the Pacific are the new normal.

“It used to be up, or down. Now, it is sideways,” said physiological ecologist Brian Beckman, of the National Oceanic and Atmospheric Administration’s Northwest Fisheries Science Center in Seattle.

That’s bad news for endangered orcas that rely on salmon for food. When salmon decline, orcas suffer.

Pacific Hake Researchers Hustle to get U.S. Data into Stock Assessment After Government Shutdown

February 1, 2019 — SEAFOOD NEWS — The Pacific Hake Joint Technical Committee, comprising both U.S. and Canadian scientists, is hustling to include U.S. Pacific hake age data in the coastwide draft stock assessment, the Committee said in an email to interested parties this week.

The researchers made the update this week after the partial U.S. government shutdown ended. U.S. scientists Ian Taylor and Aaron Berger, both with the NMFS Northwest Fisheries Science Center, were furloughed during the shutdown. The JTC is responsible for producing the coastwide whiting stock assessment upon which both countries’ allocations are based.

At the time of the shutdown in December 2018, U.S. age data was not included in the modelling. Canadian researchers said then they would do their best to produce the stock assessment based on information they had at the time. The draft assessment is due for publication on Feb. 6.

In this week’s email notice, the JTC said it will “present the assessment based on the modelling done so far, without 2018 age data included for the base model and sensitivities. The Executive Summary will be based on the model which does not include 2018 age data.”

However, they are still hoping to get 2018 U.S. age data included.

“If this happens within the next few days, the model with 2018 age data included will be run as an MCMC and presented as an appendix with all projections and decision tables, the same as what appear in the Executive Summary,” the JTC said in the email. “It will be subject to review and can be chosen to be the model for providing advice by the [Scientific Review Group] should they choose to do so.”

The SRG is scheduled to meet Feb. 19-22 in Vancouver, British Columbia, to review the assessment.

Salmon to lose sense of smell as CO2 levels rise

December 19, 2018 — As atmospheric CO2 levels continue to rise, increasing amounts of carbon dioxide will be absorbed into the ocean. New research suggests rising CO2 levels in the ocean could disrupt the olfactory abilities of coho salmon.

Salmon rely on their sense of smell to track prey, find mates and navigate their way back upstream to spawn. According to the new study, published this week in the journal Global Change Biology, a compromised sense of smell would pose a serious threat to the health of salmon populations.

Lab experiments showed rising acidity levels caused by elevated CO2 levels inhibits salmon’s already vulnerable sensory-neural system.

“Our studies and research from other groups have shown that exposure to pollutants can also interfere with sense of smell for salmon,” Evan Gallagher, a professor of toxicology at the University of Washington, said in a news release. “Now, salmon are potentially facing a one-two punch from exposure to pollutants and the added burden of rising CO2. These have implications for the long-term survival of our salmon.”

ALASKA: Researchers work on better model for impact of fishery closures

November 21, 2018 — Fisheries managers are faced with a firestorm every time they decide to close a fishery because of poor returns or low population numbers. A new economic model is trying to help them see into the future to understand the effects of a closure before it happens.

Researchers from the National Oceanic and Atmospheric Administration and the University of Washington worked together on the model, finished in 2017 and published in the journal Marine Policy this past September.

It takes into account items like fishery participation, the amount of each vessel’s annual revenue that comes from the affected fishery, which vessels participate in other fisheries and the value of the fishery; the aim is to calculate the total impact when managers have to limit or close a fishery.

The origin of the idea came after a disastrous broad closure in salmon fishing on the West Coast in 2008. The closure, caused by poor salmon returns correlated to unfavorable ocean conditions, resulted in a federal disaster declaration and a $170 million relief distribution.

Had officials and fishery managers been able to estimate the impact better, relief funds might have been distributed sooner, said Kate Richerson, a marine ecologist with NOAA’s Northwest Fisheries Science Center and the lead author of the study.

New Tech Makes Scientific Data Cheaper And Easier To Secure

September 18, 2018 — To understand what climate change is doing to the Pacific Ocean scientists need data.

Lots of it.

Traditionally, data has been expensive to secure because it involves large equipment and ocean voyages. But the miniaturization of technology and some clever new machines mean scientists are now getting lots of data — sometimes delivered via phone to the comfort of an office chair.

A good example can be found on the deck of the Forerunner, a small Clatsop Community College research vessel that sails out of Astoria.

A deck hand lowers a detector the size of a suitcase into the crystal blue waters of the Pacific. National Oceanic and Atmospheric Administration fisheries biologist Curtis Roegner is using it to look for a scanner on the sea floor.

“There. Found it,” he said. “OK, so here it’s recognizing that I’ve found one of our scanners and here’s its code number. It’s out there and we could talk to it. And now we could tell it to release from the bottom, pop-it-up and retrieve it.”
