Fishery council must act to reduce Alaska halibut bycatch

December 13, 2021 — The North Pacific Fishery Management Council, or NPFMC, has hardly been an Alaska household name, but we think it should become one. The 11-member council makes fisheries policy for the North Pacific Ocean that greatly shapes Alaskans’ livelihoods and lives, including an awfully big decision in the coming days that all Alaskans should know about.

This decision is an “all the marbles” decision to reduce — or to fail to reduce — how much halibut the Seattle-based Bering Sea groundfish trawl fishery can catch and discard as bycatch. Bycatch is when a “non-target” species of fish is accidentally caught while fishing — and is almost always discarded, often dead or dying, back to the ocean.

This is a very important decision for all Alaskans who care about our fisheries and our halibut. We believe halibut trawl bycatch caps must be substantially reduced. We believe most Alaskans feel similarly.

Right now, 3.3 million pounds of halibut are caught and discarded by the Bering Sea trawl fleets every year. Of the various trawlers in the Bering Sea, the 19 vessels that constitute the groundfish bottom trawl fleet — also known as the “Amendment 80″ fleet — are the biggest contributors to halibut bycatch.

NPFMC approaches pivotal decision on halibut bycatch, with USD 100 million potentially at stake

December 9, 2021 — The North Pacific Fishery Management Council (NPFMC) is once again considering whether or not to implement abundance-based management for halibut bycatch on the groundfish fleet, a decision stakeholders say could cost Alaska’s Amendment 80 fleet over USD 100 million (EUR 88 million).

The council faces four separate alternatives on how to handle the amount of halibut bycatch the Amendment 80 fleet – which harvests various flatfish, rockfish, Atka mackerel, Pacific Ocean perch, and Pacific cod in the Bering Sea/Aleutian Islands and Gulf of Alaska – should be allowed to catch. The four alternatives call for the council to either continue with the status quo on halibut bycatch, or ask the Amendment 80 fleet to reduce it by various amounts, up to a maximum of 40 percent.

Pacific halibut stock increases after four years of decline

December 7, 2021 — The Pacific halibut stock appears to be on an upswing that could result in increased catches for most regions in 2022.

At the interim meeting of the International Pacific Halibut Commission last week, scientists gave an overview of the summer setline survey that targets nearly 2,000 stations over three months. The Pacific resource is modeled as a single stock extending from northern California to the Aleutian Islands and Bering Sea, including all inside waters of the Strait of Georgia and the Salish Sea.

The survey results showed that coast-wide combined numbers per setline increased by 17% from 2020 to 2021, reversing declines over the past four years. The coast-wide weights of legal size halibut (over 32 inches) also increased by 4%.

“We’re seeing some new trends this year,” said Ian Stewart, lead scientist for the IPHC, which has managed the fishery for the U.S. and Canada since 1923. “The first is we saw some improving trends from our survey that correspond to a shift both in the fish and in the fishery to younger fish.”

Two Trawl Surveys in Northern Bering Sea Show Overall Decline in Many Species

November 30, 2021 — Results from two annual surveys in the northern Bering Sea this summer, one using bottom trawl and one using a surface trawl, show a decline in sea temperatures since the 2019 survey. Last year’s surveys, conducted by the National Oceanic and Atmospheric Administrations’ Fisheries branch, were cancelled due to Covid-19. This year’s surveys showed the precipitous drop in snow crab and “large declines in the Bering Sea include walleye pollock, saffron cod, and various types of jellyfish.”

The presentations, reported by KNOM.org on November 10 and November 19, were part of the Strait Sciences program presented via Zoom reported Marion Trujillo of KNOM.

The surveys cover a grid from Cape Wales, the westernmost point on the North American mainland in the Bering Strait south to Nunivak Island, west of Bethel, AK.

“At this moment we’ve been in a very long stanza for warming. But we’ve dropped down a little bit. Both not only on the bottom temperatures but the surface temperatures. And I think there’s kind of a hope that maybe we are going to see us go into a cold stanza for a while, and start to cool down the Southeastern Bering Sea. But, this might also just be a little bit of variation, and (it will) jump back up. Next year is going to tell us a whole lot about what is happening,” NOAA research scientist Lyle Britt said in the presentation.

Surface Trawl Survey Reveals Shifting Fish Populations

November 23, 2021 — Researchers are predicting low fish runs in the Norton Sound and Northern Bering Sea region again next year, according to research biologist Jim Murphy.

Murphy, who works with the Salmon Ocean Ecology and Bycatch Analysis Group at the Alaska Fisheries Science Center in Juneau, presented the findings of the recent 2021 surface trawl survey during a Strait Science event. The survey, which tracks marine life across the surface and midlevel of the northern Bering Strait, was conducted in September this year. Researchers studied salmon, seabirds, shrimp, zooplankton and several other marine species.

The surface trawl survey has been conducted every year for almost two decades, and Murphy says when the survey is conducted is crucial. “The timing of the survey was established at the beginning to match the timing of marine entry and dispersal of juvenile salmon from estuarine habitats, and we’ve attempted to keep the timing of the survey as consistent as possible.”

Though the primary purpose of the surface trawl is to track pelagic fish, or species found in the middle and upper water columns, and invertebrate populations, researchers also collect zooplankton and sediments, as well as bottom-dwelling fish, crab and invertebrates.

ALASKA: Dunleavy administration announces formation of bycatch task force

November 22, 2021 — Gov. Mike Dunleavy’s office recently announced that it’s setting up a task force to tackle the thorny issue of trawler bycatch.

Bycatch is what fishermen catch unintentionally — fish they aren’t targeting that get caught up in their nets, anyway. Federal bycatch data shows trawl fisheries in the Bering Sea and Gulf of Alaska this year have caught tens of thousands of chinook salmon, millions of pounds of halibut and hundreds of thousands of crabs.

Meanwhile staple species like chinook salmon, red king crab and halibut have been on the decline, forcing subsistence, sport and commercial fishermen to pack up nets or reduce harvest.

“We’ve had a reduction in or closure of the crab fisheries in the Bering Sea. The [North Pacific Fishery Management] Council is discussing how to deal with halibut bycatch, and I think there’s a lot of perception that there are bycatch issues associated with what’s happened with salmon in Western Alaska systems,” said Alaska Fish & Game Commissioner Doug Vincent-Lang.

Alaska crab population crash blamed on mysterious mortality event

November 5, 2021 — A crash in crab populations in the U.S. state of Alaska is being partially blamed on a mortality event scientists cannot fully explain.

A catastrophic drop in Alaska’s snow crab population led the state to set a much lower quota for the upcoming season. Along with a significant drop to the Bering Sea bairdi crab quota and the closure of the winter Bristol Bay red king crab fishery, Alaska’s overall crab fishery could lose up to USD 100 million (EUR 86.5 million) or more in value in the 2021-2022 season, according to the Alaska Bering Sea Crabbers.

Dungeness emerges as Alaska’s top crab fishery

November 4, 2021 — It’s hard to believe, but Dungeness crab in the Gulf of Alaska is now Alaska’s largest crab fishery — a distinction due to the collapse of stocks in the Bering Sea.

Combined Dungeness catches so far from Southeast and the westward region (Kodiak, Chignik and the Alaska Peninsula) totaled over 7.5 million pounds as the last pots were being pulled at the end of October.

Ranking second is golden king crab taken along the Aleutian Islands with a harvest by four boats of about 6 million pounds.

For snow crab, long the Bering Sea’s most productive shellfish fishery, the catch was cut by 88% to 5.6 million pounds this season.

The Gulf’s Dungeness fishery will provide a nice payday for crabbers. The dungies, which weigh just over two pounds on average, were fetching $4.21 per pound for 209 permit holders at Southeast who will share in the value of over $14 million.

As tribal leaders, we urge collective action for Western Alaska salmon now

November 1, 2021 — This past summer, fish racks, smokehouses and fish camps across the Yukon and Kuskokwim Rivers and Norton Sound region in the western part of our state stood empty. Chinook and chum salmon are critical to the lifeblood of our nearly 100 regional tribal communities and are central to our cultures. However, they did not return this year throughout much of our regions. Our people are now facing a winter without this essential food source and missing an essential part of our traditions and way of life.

While tribes along our rivers were not allowed to harvest a single salmon or were severely restricted in their harvests last summer, the largely out-of-state industrial Bering Sea pollock trawl fleet is allowed to catch vast quantities of salmon as bycatch. In 2021 alone, 12,000 Chinook salmon and over 500,000 chum salmon thus far have been caught as bycatch in the Bering Sea pollock fishery. Wasting is not acceptable according to our cultural values, which guide us to take only what we need and use everything we take. This level of bycatch – viewed by the industry as discarded salmon – is disrespectful and should not be allowed.

Tribes and communities have been doing our part to help protect and restore our salmon runs by foregoing our subsistence harvests, engaging in research, and testifying about our experiences amid this salmon collapse. Earlier this month, we called on the North Pacific Fisheries Management Council to do their part by reducing this bycatch to zero for 2022 and taking strong steps towards a long-term solution to eliminate salmon bycatch and restore salmon runs to abundance.

Study Finds Growing Potential for Toxic Algal Blooms in the Alaskan Arctic

October 6, 2021 — Changes in the northern Alaskan Arctic ocean environment have reached a point at which a previously rare phenomenon—widespread blooms of toxic algae—could become more commonplace. These blooms potentially threaten a wide range of marine wildlife and the people who rely on local marine resources for food. That is the conclusion of a new study about harmful algal blooms of the toxic algae Alexandrium catenella published in the journal Proceedings of the National Academy of Science. Microscopic algae in the ocean are most often beneficial and serve as the base of the marine food web. However, some species produce potent neurotoxins that can directly and indirectly affect humans and wildlife. 

Dormant Cysts Could Seed a Toxic Bloom

The study was led by scientists at the Woods Hole Oceanographic Institution (WHOI) in collaboration with colleagues from NOAA’s Northwest Fisheries Science Center and researchers in the United States, Japan, and China. It looked at samples from seafloor sediments and surface waters collected during 2018 and 2019. Samples were taken in the region extending from the Northern Bering Sea to the Chukchi and Beaufort Seas north of Alaska. The sediment samples allowed the researchers to count and map Alexandrium cysts. The cysts are a seed-like resting stage that lies dormant in the seafloor for much of the year, germinating or hatching only when conditions are suitable. The newly hatched cells swim to the surface and rapidly multiply using the sun’s energy. This produces a “bloom” that can be dangerous due to the family of potent neurotoxins, called saxitoxins, that the adult cells produce.

When the algae are consumed by some fish and all shellfish, those toxins can accumulate to levels that can be dangerous to humans and wildlife. In fish, toxin levels can be high in digestive and excretory organs (e.g., stomach, kidney, liver), but are very low in muscle and roe.  Although fish can be potential toxin vectors, the human poisoning syndrome is called paralytic shellfish poisoning. Symptoms range from tingling lips, to respiratory distress, to death. The toxin can also cause illness and death of marine wildlife such as larger fish, marine mammals, and seabirds. This is of particular concern for members of coastal communities, Alaskan Native Villages, and Tribes in northern and western Alaska who rely on a variety of marine resources for food.
