A fish mystery solved using genetic testing

October 17, 2019 — The population of cod in the Northern Bering Sea has increased immensely since 2010, and scientists are using fish DNA to find out why.

Think of it like a genetic ancestry test, but for fish.

Until recently, pacific cod were rarely found in the Northern Bering Sea. A 2010 survey showed cod made up only three percent of the entire fish population. That’s been changing, fast.

A survey in the summer of 2017 showed that number shot up 900 percent.

Ingrid Spies is a research fisheries biologist who led the way on this research to determine whether the population spike is evidence of a growing population or of an existing population migrating from elsewhere?

One thought was that cod could have migrated from Russia or the Gulf of Alaska, where they observed cod numbers decline significantly in 2017. Scientists were able to come to a conclusive answer to the question using genetic testing.

New Seafloor Maps Reveal Habitat Sculpted by Ancient Glaciers

September 24, 2019 — The following was released by NOAA Fisheries:

New seafloor maps show for the first time the course of ancient ice masses. They show how they shaped essential habitat for the western Gulf of Alaska’s abundant fish, seabirds, and marine mammals.

Scientists wove together historical and modern data—from century-old hand-drawn charts to modern multibeam surveys. They created a highly detailed view of the seafloor and its geological features. The results will help scientists better understand the habitat requirements of many species and the oceanographic processes that influence their success.

The western Gulf of Alaska is both ecologically and economically important. Shelikof Strait, a major feature of the region, holds special importance as spawning ground for the Gulf’s biggest stock of walleye pollock. Together with other Alaska pollock stocks, they are the target of the world’s largest fishery. Shelikof Strait is also home to rare species like the mysterious Pacific sleeper shark. Within the Gulf of Alaska bottom trawl survey area, almost half of all sleeper shark occurrences are in Shelikof Strait.

Despite its importance, until now much of the western Gulf of Alaska had not been mapped in sufficient detail to describe the geological features of this vital habitat. To create and analyze new maps, NOAA Fisheries and U.S. Geological Survey scientists teamed up to bring together geographical and geological expertise.

Salmon studies: North Pacific project trawls for data, funding

May 24, 2019 — “I like to say to people that after 100 years of research, we know a lot about salmon. But what we need to know most, we mostly don’t know,” said fisheries scientist Richard Beamish following the first International Year of the Salmon expedition this year. “We can’t forecast how a changing ocean ecosystem is going to affect salmon.”

Beamish, who organized the expedition and is an emeritus scientist at Fisheries and Oceans Canada’s Pacific Biological Station in Nanaimo, British Columbia, is seeking $1.5 million from governments, the private sector and nonprofit organizations for a 2020 expansion. The program’s researchers would like to carry the program into 2021 to continue their work on North Pacific salmon stocks and climate change.

The 2019 expedition, which was a signature project of the program, kicked off in February with an international winter salmon study in the deepest regions of the Gulf of Alaska. The 2020 expedition would put two Russian trawlers on the water to expand the work of a pilot 25-day single-vessel survey that ran early this year in the Gulf of Alaska.

A bigger survey is in the works for 2021. It would involve five ships surveying the entire North Pacific Ocean. The cost of that project is estimated at $10 million.

ALASKA: Study pinpoints trend toward fisheries specialization

May 10, 2019 — Commercial fishermen in Alaska have gotten older in the past three decades. As it turns out, they’ve become more specialized, too.

Fewer permits overall are in the water; between the early 1990s and 2014, commercial fishing permits in Alaska decreased by 25 percent. On top of that, fewer individual fishermen are moving between fisheries.

From 1988-2014, the number of individuals holding multiple permits declined from 30 percent to 20 percent, according to a study published in the journal Fish and Fisheries.

The bottom line: fishermen are increasingly putting all their economic eggs into one basket, and that makes them more vulnerable to the ups and downs of fishing.

The study was born out of a workgroup that met through the National Center for Ecological Analysis and Synthesis at the University of California Santa Barbara, said co-author Anne Beaudreau, an associate professor of fisheries at the University of Alaska Fairbanks.

The original intent was to study the long-term effects of the 1989 Exxon Valdez oil spill, but the data on fisheries specialization arose out of that work, she said.

“As we worked on this, we realized there are so many things that have caused long-term changes in the Gulf of Alaska; in the fisheries, it’s really hard to see the long-term effects of the oil spill,” she said. “A lot of the focus of the working group was on the biological effects … this paper sort of came out of the end of that.”

Overlooked jellyfish play big role in Gulf of Alaska

April 15, 2019 — “Jellyfish have superpowers,” assured Heidi Mendoza-Islas, a graduate student at the University of Alaska Fairbanks College of Fisheries and Ocean Sciences.

The voracious carnivores will eat almost anything that fits into their mouths. When conditions are good, they grow fast and multiply. When conditions aren’t ideal, baby jellies can transform into cysts and wait it out.

So it is no surprise that jellyfish have been successful predators in the Gulf of Alaska, Mendoza-Islas said. But few studies have focused on the role jellyfish play in the Gulf’s ecosystem or how jellyfish affect commercially important finfish, such as pollock. Mendoza-Islas wants to change that.

Alaska Fish and Game forecasts a 2019 salmon catch of 213.2 million fish

April 10, 2019 — Alaska fishermen could catch 85 percent more salmon this year (nearly a hundred million more) if state forecasts hold true.

That’s good news for fishermen in many Gulf of Alaska regions who in 2018 suffered some of the worst catches in 50 years.

The Alaska Department of Fish and Game is predicting a total salmon catch of 213.2 million fish for 2019, compared to about 116 million salmon last year. The increase comes from expectations of another big haul of sockeyes, increases in pinks and a possible record catch of chum salmon.

The harvest breakdown calls for 112,000 chinook salmon in areas outside of Southeast Alaska. The catch for the Southeast troll fleet, which is determined by a treaty with Canada, will be 101,300 kings, a 5,600-fish increase.

International study to shed light on the mysterious lives of salmon at sea

March 29, 2019 — Scientists know surprisingly little about a salmon’s life outside of their freshwater and nearshore habitats, but an ambitious study is attempting to change that. The International Year of the Salmon put together an expedition with 21 international scientists in the Gulf of Alaska, all in the hopes of understanding more about the mysterious lives salmon lead in the open ocean.

The International Year of the Salmon is a quasi-international organization aimed at bringing attention to all five species of Pacific salmon as warming ocean temperatures affect their survival at sea.

“We will set the conditions that we need for salmon and people to be resilient as we’re dealing with this change in climate,” Mark Saunders explained.

Saunders works for the North Pacific Anadromous Fish Commission and he helped establish the International Year of the Salmon initiative. The project is brining scientists, fishery managers and policy makers together from Japan, Russia, the U.S. and Canada in the hopes of making salmon management in the Pacific Ocean an international effort.

“We’re looking for those projects that we believe are transformational and then going after the funding to do it,” Saunders added.

One of the projects was a five-week expedition that acted as a first-of-its-kind stock survey for salmon in the Gulf of Alaska.

Predicting marine heatwaves can have economic implications

March 6, 2019 –The Gulf of Alaska is once again experiencing a marine heatwave. This follows the infamous warm-water event known as the “blob,” that formed back in 2014, which scientists have tied to seabird die-offs and declining Pacific cod stocks.

Scientists around the world are trying to predict these events, but there are economic implications to forecasting the future.

Scientists around the world are working to understand the impacts of marine heatwaves as they become more common. They also want to predict when and where the world’s oceans will heat up.

“If I gave you this information about the future, what would you possibly even do with it?” Alistair Hobday said. “And people’s first reaction is, ‘nothing, I don’t know what I would do.’”

Hobday is a research scientist with Australia’s Commonwealth Scientific and Industrial Research Organisation. Hobday said the predictive models for marine heatwaves are about 60 percent accurate currently, slightly better than a flip of a coin.

He wants to boost that number to 80 percent, and he said marine heatwave forecasts have practical applications.

NPFMC Considers Rationalizing Bering Sea Pacific Cod Fishery

March 5, 2019 — SEAFOOD NEWS — The North Pacific Fisheries Management Council is considering rationalizing the Bering Sea/Aleutian Islands trawl pacific cod fishery after voting to take action on the fishery at its February meeting. A number of alternatives for management changes to the fishery have been released for public review; the council will be considering final actions during upcoming meetings.

The fishery is facing a number of issues, including decreasing stocks, an increase in participation and an increasingly shortened season. Among the actions that the council is considering to address these issues is the introduction of a catch-share system, in which quota would be allocated.

The council is also weighing up its options to address the increasing prevalence of catcher/processor vessels — also known as motherships — which is resulting in a loss of deliveries to shore-based processing facilities. The council is looking at various ways to limit the participation of certain vessels acting as motherships.

At its June 2018 meeting, the council adopted a purpose and need statement, which acknowledged recent increases of motherships and a decrease Pacific cod deliveries to shoreside processors.

“The council is concerned about the impacts of the recent increases and potential for future growth in offshore deliveries of Pacific cod to … vessels operating as motherships, and the potential impacts those increases could have on shoreside processors, communities and participating catcher vessels,” the statement reads.

The statement also notes that the race-for-fish management system has resulted in a “decreased ability to maximize the value of the fishery … negatively impacting fishery participants,” as well as discouraging fishing practices that can minimize bycatch.

“Additional entrants could exacerbate these issues and threaten the viability of the fishery,” the statement reads. “The council is considering options to improve the prosecution of the fishery, with the intent of promoting safety and increasing the value of the fishery.”

TAC for the fishery has been reduced in recent years. While the cod fishery in the gulf of Alaska has fared worse, with its TAC being cut by 80 percent, the TAC for the Bering Sea/Aleutian Islands fishery was cut by nearly 50 percent last year.

At the council’s February meeting, Darral Brannan, a consultant for the NPFMC, noted that the 2019 Bering Sea/Aleutian Islands trawl Pacific cod A season was the fishery’s shortest ever.

“In 2018, the A season for the trawl CV sector closed on February eleventh. This year, the fishery closed February first. It was 12 full days of fishing. It covered 13 calendar days, but it was noon to noon,” he told the council. “It was the shortest ever A season that we’ve had.”

According to Brannan, in 2018, 18 percent of the Pacific cod from the fishery was delivered to motherships, rather than shoreside processors. Comparatively, in 2019, mothership deliveries rose to 30 percent.

The council is considering a number of different options to limit activity in the Bering Sea/Aleutian Islands Pacific cod trawl fishery, which are outlined in six alternatives.

At its February meeting, the council voted on a motion to bifurcate alternatives two, three and six in order to address concerns around motherships separately from issues surrounding higher levels of participation in the fishery. (Alternative one is for the council to take no action). Alternatives two, three and six specifically address the issues with increased mothership participation in the fishery, and these have now been released for public review.

Respectively, these alternatives would involve: limiting the number of motherships that can take Bering Sea/Aleutian Islands Pacific cod deliveries; limiting the total amount of Pacific cod that can be delivered to motherships; or prohibiting certain vessels from participating in the fishery as motherships.

The council received several letters urging it to take action on this issue — including one from the Pacific Seafood Processor Association, a nonprofit trade association comprised of nine processing companies, located in 18 communities throughout Alaska. Pacific Seafood Processor Association has members that operate processing facilities in Dutch Harbor, King Cove, Sand Point, Akutan and others. The letter urged the council to expediently address the issue.

“This issue continues to have meaningful impacts for BSAI coastal communities, who rely heavily on volume fisheries like pollock and cod,” the letter states. “All of these local governments levy local raw fish taxes on the value of fish landed at local processing facilities and inshore floating processors.”

The council also received public comment requesting that it take a more mediated approach to limiting motherships.

In a letter to the council Matthew Doherty, president and CEO of United States Seafoods, which operates the catcher processor Seabreeze Alaska, argued that the Seabreeze Alaska has an “extensive history in the fishery” and that United States Seafoods depends on the ability of its catcher vessels to deliver cod offshore.

Doherty argued that the United States Seafoods has been “a good citizen” in the fishery by coordinating with other stakeholders — even suspending its operations in the Aleutian Islands cod fishery in 2018 in an attempt to aid the Adak plant’s success.

“The SEAFREEZE ALASKA’s participation in the fishery is NOT part of the ‘recent increases . . . in offshore deliveries’ noted as problematic in the Council’s purpose and need statement for this action,” the letter states. “If the Council restricts offshore cod processing, we recommend the action be narrowly focused on recent problematic changes in the fishery.”

While this item was originally scheduled for final action at the council’s June meeting, according to the most recent draft of the council’s upcoming meeting schedule, the item has been moved up to the council’s next meeting, which is in April.

The issues surrounding increasing participation in the fishery are being addressed as a separate agenda item. The council also voted on a motion to develop a scoping paper, which may be used to develop a comprehensive Bering Sea/Aleutian Islands cod trawl catcher vessel management program.

The scoping paper will analyse the possibility of introducing Pacific cod endorsements for trawlers with LLP licenses, which would rationalize the fishery.

A NPFMC Advisory Panel, which is made up of various fishery stakeholders, offered the council both arguments for and against this action. Meetings from the AP’s February meeting noted that some of the panel argued that a catch share program would the best solution for protecting stock levels and giving harvesters, processors and their communities the chance to maximize the value of the fishery.

Other fisheries have been rationalized in the past, including rockfish in the Gulf of Alaska and Bering Sea/Aleutian Islands crab.

“The problems currently being faced by the BSAI trawl CV cod fishery are similar in nature to problems previously faced by other fisheries that now operate under a catch share program,” the AP minutes state. “The multiple successes achieved under these varying programs established in the North Pacific now lead the participants in the BSAI cod trawl fishery to believe that the development of a cooperative-based program for BSAI Pacific cod is the best solution.”

However, not all of the panel was onboard. The minutes state that a catch share program for Bering Sea/Aleutian Islands trawl cod may make it harder to enter the fishery.

“Catch share programs that allocate quota to LLPs can make access to the fishery more expensive for new entrants and have potentially negative impacts on communities,” the minutes state.

Some public comments reflected a concern that, should the council establish a catch share program in the Bering Sea/Aleutian Islands fishery, it could negatively impact other fisheries. Among them was a letter from Patrick O’Donnell, the owner and operator of the F/V Caravelle, a trawler homeported in Kodiak. O’Donnell expressed concern that an action on the Bering Sea/Aleutian Islands fishery could have an impact on the Gulf of Alaska cod fishery and requested that the council postpone further action until it can ensure that Gulf of Alaska fishermen wouldn’t be affected.

“GOA trawlers have asked for a catchshare management plan, with tools to better manage bycatch in the Gulf, and I would like to see that program move forward at the same time as any changes to the (BS cod fishery),” the letter states. “Any action that moves the cod TLAS fishery closer to a rationalized program has the potential to create spill-over effects in the GOA.

“It will create advantages for boats that have a guaranteed share in the BS, and give them an incentive to race for fish in the GOA first, then go harvest their share in the Bering Sea.”

The scoping paper is scheduled for council discussion at its October meeting.

All the alternatives that the council is considering, along with staff analysis and public comments can be found on the NPFMC’s website. Those looking to provide public comment prior to the council’s April meeting can do so via the NPFMC’s online comment portal, or at the meeting itself.

ALASKA: Part of Bering Sea Pacific cod fishery could move toward quota system

February 20, 2019 — About a year after federal regulators dramatically cut the Pacific Cod quota in the Gulf of Alaska, some fishermen in the Bering Sea say there are too many boats fishing for the declining species.

The North Pacific Fishery Management Council is looking into the problem, but potential solutions are likely to be controversial.

Since Pacific cod stocks crashed in the Gulf of Alaska in recent years, members of the fishing industry say fishermen are focusing their efforts farther west.

Tom Enlow is the president of UniSea, which operates a large shore-side processor in Unalaska. He said more vessels — especially trawlers — are crowding the fishing grounds. He also said there are more offshore processors competing for their cod.

“You’re seeing people who have historically not participated in these fisheries – as a processor standpoint – now coming into the fishery,” Enlow explained. “So there’s a lot of excess capacity now and pressure on this resource.”
