Climate Change Hitting Top U.S. Fishery in the Arctic: NOAA

December 11, 2019 — Climate change is causing chaos in the Bering Sea, home to one of America’s largest fisheries, an example of how rising temperatures can rapidly change ecosystems important to the economy, U.S. federal government scientists said in a report on Tuesday.

Rising temperatures in the Arctic have led to decreases in sea ice, record warm temperatures at the bottom of the Bering Sea and the northward migration of fish species such as Pacific cod, the U.S. National Oceanic and Atmospheric Administration, or NOAA, said in its 2019 Arctic Report Card.

While the changes are widespread in the Arctic, the effect on wildlife is acute in the eastern shelf of the Bering Sea, which yields more than 40% of the annual U.S. fish and shellfish catch.

“The changes going on have the potential to influence the kinds of fish products you have available to you, whether that’s fish sticks in the grocery store or shellfish at a restaurant,” said Rick Thoman, a meteorologist in Alaska and one of the report’s authors.

US Pacific cod TAC set to drop below Russia’s next year, 2021 reduction also likely

December 3, 2019 — The total allowable catch (TAC) for US Pacific cod will drop again in 2020 and beyond, as Russia increases its TAC way past the Alaskans and also has now Marine Stewardship Council (MSC) for a large chunk of its fishery.

Alaska’s Pacific cod biomass is down considerably in 2020 and will drop further in 2021, according to the draft stock assessment and fisheries evaluation (SAFE) report on stocks in the eastern Bering Sea and Aleutian Islands, which will be discussed Monday at the North Pacific Fishery Management Council (NPFMC) meeting, held from Dec. 2-10, 2019, at the Hilton Hotel in Anchorage, Alaska.

At the end of the meeting, TACs for Pacific cod, pollock and other species will be recommended to the government. According to historical catch data, the last time Russia had a higher Pacific cod catch than the US and Canada was 1987, when it was 175,271t compared to 150,591t.

Alaska’s northern rock sole another climate change winner

December 3, 2019 — Count Alaska’s northern rock sole among the fish species that appear to have more promise as water temperatures continue to increase as a result of climate change, Alaska TV station KTUU reports.

Using biomass data collected from 1982 through 2014 as well as wind and temperature data, Dan Cooper, a fish biologist with the US National Oceanic and Atmospheric Administration, and his team have determined that the flatfish species has higher reproductive success in warmer years, according to the NBC affiliate.

Though its females grow to a size of up to 27 inches in length and males up to 19 inches, northern rock sole is harvested significantly less than pollock and Pacific cod, in Alaska. The North Pacific Fishery Management Council set the acceptable biological catch for the fish in the Bering Sea and Aleutian Islands at 143,000 metric tons for 2020, yet in 2018 only 60% of the total allowable catch was harvested, the news service noted.

ALASKA: Warmer Bering Sea may benefit an Alaskan flatfish

November 27, 2019 — While the repercussions of climate change are complex and many impacts are unknown, newly published research suggests that one winner in a shifting environment is Alaska’s Northern rock sole.

The Northern rock sole is a flatfish that is commercially harvested, although it is fished significantly less than Pollock and Pacific cod.

Females grow up to 27 inches, while makes grow up to around 19 inches. The North Pacific Fishery Management Council set the acceptable biological catch for the fish in the Bering Sea and Aleutian Islands at 143,000 metric tons for 2020, yet in 2018 only 60% of the total allowable catch was harvested.

Research by NOAA Fisheries biologists suggest that the fish have higher reproductive success in warmer years, meaning that a higher percentage of eggs laid will grow to become part of the catch-able population.

The investigation started after surveys of juvenile showed dramatically different results in the same location.

“One year we went in this area between Nunivak Island and Cape Newenham offshore and we found very high densities of the animals. We estimated that there were billions and that was in 2003 – a warm year,” said Dan Cooper, a research fisheries biologist with NOAA’s Alaska Fisheries Science Center.

He said it’s the opposite in cold years.

ALASKA: Northern Bering Sea trawl survey shows fisheries in flux

November 19, 2019 — Norton Sound red king crab are moving, Arctic cod numbers have dropped significantly and Pacific cod are continuing to increase as the Northern Bering Sea ecosystem undergoes drastic change. That’s all according to preliminary results from a National Oceanic and Atmospheric Administration trawl survey this summer in the Northern Bering Sea (NBS).

Before Lyle Britt even began leading the NOAA Fisheries’ study of the NBS in September, he anticipated seeing more warm water fish in a region that stretches from Nunivak Island north to the Bering Strait.

“We can tell that the ecosystem is very much in flux up here,” Britt said. “We’re seeing expansion of ranges of some fish and invertebrates, and we’re seeing the retraction of others. Now how permanent or ephemeral those are, I think is still in question.”

As an example of a species that’s expanding its range based on what was discovered in the 2010 baseline survey of the Northern Bering Sea, Britt points to Pacific cod.

“Between 2010 and 2017 there was about a 900% increase in the amount of Pacific cod we saw in the Northern Bering Sea region, based on that biomass or total weight estimate,” he said. “That number sounds really dramatic in part because there were so few in 2010 and now there are some. That number increased between 2017 and 2019 by about 30%, so it’s continued to go up.”

ALASKA: City of Adak Asks Court for One-Year Stay to Keep Plant Open for Cod A Season

November 19, 2019 — SEAFOOD NEWS — Last week the city of Adak asked a federal court to stay their order from last March — until January 1, 2021 — so the city’s only processing plant can operate during the Pacific cod season next year.

The March 2019 court decision agreed with plaintiffs representing the Bering Sea bottom trawl fleets that target flatfish, mackerel and cod, that Amendment 113, setting a 5,000 mt cod set-aside for remote villages in the Aleutian Islands, was not compliant with the Magnuson-Stevens Act.

The court vacated Amendment 113 and instructed the North Pacific Fisheries Management Council to work on an amendment that would comply with the legislation in specific areas.

The Council took up the issue, beginning an arduous process of analysis, developing alternatives, and public comment that will take at least another 18 months.

Meanwhile, representatives of the Adak plant, central to the economy of the 350-resident community, began an ambitious effort to find a pathway that would allow the set-aside to continue while the Council worked on corrections to a new amendment. But their efforts fell short, whether it was a plea for emergency action or language in new federal legislation for a temporary fix, last summer.

Even though the Council asked industry sectors to work together for a solution that could keep the Adak plant viable, there was no longer any authority providing a separate allocation for Adak, and little incentive to find an industry-based workaround.

In addition, all fleets targeting Pacific cod in the Bering Sea and the Aleutian Islands were well aware of the recent situation for cod stocks. Recent scientific assessments indicate the biomass is increasing in the northern Bering Sea and decreasing in traditional areas. Was the biomass moving north? How fast? Could the fish be crossing over to Russian waters? The ‘race for fish’ nature of the BSAI fishery made even the previously acceptable 5,000 mt set-aside — now vacated and available to anyone — more valuable than it was a few years ago.

Last Wednesday’s Memorandum in Support of Defendant-Intervenors’ Motion for Limited Relief From Judgment and Indicative Ruling included declarations of support from Adak as well as the Alaska Department of Fish and Game, Golden Harvest plant owner Jason Ogilvie, the Adak School District, and other private enterprises that rely on the winter operations of the plant.

City Manager Lyle Lockett noted that without continuous operation of its sole fish processing plant, Adak will see cascading economic impacts causing irrepairable harm to the community, including the city stopping subsidies to the school district, the medical clinic, the library, the gymnasium, and the community center.
“Shutting down the City Hall building would force all of these services to scramble to find a new location on the island, perhaps in private residences, which would be disruptive and likely expensive for Adak’s residents,” according to the memorandum.

Adak’s only school serves 19 students, 13 whose parents are employed directly or indirectly through the Adak plant. If enrollment drops to 10 or less, the state of Alaska’s subsidies stops and the school shuts down.

Both the crab and cod fleets that deliver to Adak would have no option other than Dutch Harbor to deliver their catch to — a 450-mile one-way trip.

The request asks the court to respond by January 10, 2020, ten days before the A season begins next year.  The motion supporting the stay was filed while the original decision is under appeal, and would be subject to that ruling if it came before.

NOAA proposes humpback whale habitat protections

November 11, 2019 — NOAA’s fisheries division, the National Marine Fisheries Service, has proposed creating a number of critical habitat sites ranging from the Channel Islands in southern California to the Bering Sea, including the waters off Juneau.

The critical habitats, created with the aim of protecting the feeding areas of three separate groups of humpback whales, or Megaptera novaeangliae, will not affect anything except for federal agencies seeking to use those waters for other purposes, said Lisa Manning, an official with NOAA. Her presentation to the public on the proposed habitats was held at University of Alaska Southeast on Thursday evening, and was attended by more than 30 people.

“A critical habitat does not establish a sanctuary or preserve. It does not affect recreational activities. It does not affect private lands,” Manning said. “It only affects federal activities.”

The proposed habitats, which cover 175,182 square nautical miles in total, are the traditional feeding areas of three of the 14 major humpback whale distinct population segments (DPS), Manning said. The three groups that come to Alaska and California to summer and feed spend the rest of their time west of Mexico, west of Central America and east of Taiwan respectively. These three groups are currently threatened, and protecting their feeding areas may help them to regain their footing, Manning said. Some of these groups may number 2,000 whales or less.

Why Are Birds and Seals Starving in a Bering Sea Full of Fish?

November 4, 2019 — The shipment arrived airfreight: 47 seabird carcasses collected by the Bering Strait villagers of Shishmaref.

Marine biologist Gay Sheffield drove to the airport on an August day to pick up the grisly cargo and bring it back to a laboratory just off the main street of this northwest Alaska town.

Inside a cardboard box, Sheffield found mostly shearwaters, slender birds with narrow wings — also kittiwakes, crested auklets, thick-billed murres, a cormorant and a horned puffin. Most were painfully skinny, bones protruding like knife-edged ridges.

“They starved to death,” Sheffield said. “Why?”

The birds should have been able to fatten on small fish, krill and other food that typically abound in the northern Bering Sea, a body of water so rich in marine life that gray whales, after they winter off Mexico, swim more than 5,000 miles north to feed here each summer.

But as climate change warms the die-offs of seabirds and marine mammals have been on the rise. The grim tally includes a nearly fivefold increase in ice-seal carcasses spotted on shore, strandings of emaciated gray whales, and near the St. Lawrence Island village of Savoonga, a discouraging spectacle: auklets abandoning seaside nests as their chicks succumb to hunger.

Agencies still looking for answers in marine mammal die-off

November 4, 2019 — The National Marine Fisheries Service is still trying to figure out what is causing marine mammals to die at high rates in Alaska.

In September, the National Oceanic and Atmospheric Administration declared an unusual mortality event for three types of seals in the Arctic, including bearded, ringed and spotted seals in the Bering and Chukchi seas.

“Our normal stranding numbers for ice seals is about 20 to 30 a year,” said NOAA Marine Biologist Barbara Mahoney. “So we are dealing with more than five times the dead animals that we’ve had in the past.”

But it isn’t just seals.

In May, NOAA declared an unusual mortality event for gray whales along the West Coast from Mexico to Alaska. As of Sept. 30, the agency reported a total of 121 dead gray whales in 2019.

NOAA trawl surveys estimate more cod, pollock in Bering Sea

October 29, 2019 — The results from recent US government trawl surveys of the Bering Sea are in and they estimate the biomass of pollock and Pacific cod have risen relative to previous years.

Two vessels — Alaska Knight and Vesteraalen — completed summer surveys of the eastern and northern Bering Sea from the US National Oceanic and Atmospheric Administration’s (NOAA) Alaska Fisheries Science Center.

The AFSC said in a presentation that the trawl surveys led scientists to estimate the pollock biomass at 5.46 million metric tons for the Eastern Bering Sea, a 75% year-on-year rise and 1.17m metric tons for the Northern Bering Sea, compared to the last major survey, which was performed in 2017.

For Pacific cod, the surveys led to an increased biomass estimate of 517,000t in the Eastern Bering Sea, a 2% y-o-y rise and an estimate of 368,000t for the Northern Bering Sea, up 30% from 2017.
