New Study Shows Pacific Cod Eggs are Highly Vulnerable to Changes in Bottom Temperature

February 21, 2020 — The following was released by NOAA Fisheries:

The 2013 to 2016 marine heatwave—known as “The Blob”—is the largest warm anomaly ever recorded in the North Pacific. In the Gulf of Alaska, scientists have connected low numbers of Pacific cod larvae, juveniles, and adults to loss of spawning habitat. This occured during and immediately following the heatwave. Compounding the ecological loss is the significant economic impact on the second most valuable commercial fishery in Alaska. The fishery experienced large reductions in their annual catch limits in 2018 (a 58 percent cut) and a fishery closure in 2020.

“We combined results of laboratory studies, stock assessment model output and survey data to help us better understand what happens to Pacific cod in warm and cold years,” said Benjamin Laurel, NOAA Fisheries biologist and lead researcher for this new study. “We found that the recent three-year heatwave and return to similar conditions in 2019 potentially had the greatest effect on spawning habitat for the years we had available data (1994 to 2019).”

Water temperature is an important component of fish habitat. Temperature influences every stage of a fish’s life. During the first year of life, fish eggs are particularly sensitive to changes in environmental conditions.

Laurel and colleague Lauren Rogers determined that Pacific cod eggs have a narrow optimal range for hatching success, only 3-6º C. This is much narrower than other related species like walleye pollock and Atlantic cod.

“Early life stage distribution and survival may set biogeographic boundaries and limit productive capacity for fish stocks,” added Rogers. “Pacific cod are unique among cod species; they only spawn once in a season and have eggs that adhere to the seafloor. Pacific cod females can actually place their eggs in habitats with temperatures that optimize hatch success. However, during these warm years, it may have been more challenging to find suitable habitat because the warmer water temperatures extended into the ocean depths.”

Gulf of Alaska cod exemplifies commitment to sustainability

February 19, 2020 — Recent headlines discussing a potential suspension of the Marine Stewardship Council’s certification for Gulf of Alaska Pacific cod have included some misleading and even inaccurate depictions of the status of the fishery. As the client for both MSC and Responsible Fisheries Management certifications for all Alaska Pacific cod, Alaska Fisheries Development Foundation feels it is important to provide necessary context and clarification.

Most importantly, all Alaska Pacific cod is currently certified under both the MSC and RFM programs, with only a small percentage (6 percent or less) of the commercial harvest under review in 2020 by the certification bodies. Alaska’s Pacific cod fishery is split into three primary commercial fishing regions — the Bering Sea, Aleutian Islands, and Gulf of Alaska — which will account for about 78 percent, 16 percent, and 6 percent of the 2020 harvest, respectively. Only the Gulf of Alaska harvest is under review and subject to a potential change in certification status. The Bering Sea and Aleutian Islands produce 343 million pounds of Alaska Pacific cod, and recent surveys from these fisheries show abundant populations.

To say that sustainability certification and fisheries management standards are complicated is an understatement. Yet every aspect of fisheries management in Alaska is based on the best available scientific data, effective management practices, and a precautionary approach designed specifically to sustain the long-term health of the species and ecosystem. In Alaska, we are now challenged by the fact that climate or environmental changes are often the key drivers in fisheries health and management. This makes our investment in and commitment to federal surveys, annual stock assessments, monitoring, and catch accounting data even more important.

Adherence to our robust management systems, even when climate-driven events necessitate a fishery closure, is the strongest demonstration of Alaska’s sustainable fisheries.

Gulf of Alaska cod to lose sustainability certification by March, MSC confirms

February 5, 2020 — Pacific cod from the Gulf of Alaska is expected to lose its Marine Stewardship Council (MSC) sustainability certification in the coming months due to a decline in the stock, according to the organization.

“The Gulf of Alaska Pacific Cod fishery is currently undergoing an expedited audit against the MSC fisheries standard following new information from the National Marine Fishery Service showing that the Gulf of Alaska Pacific cod stock had declined to less than B20,” said MSC Senior Public Relations Manager Jackie Marks. “This resulted in closure of the federal Gulf of Alaska Pacific cod fishery by federal fisheries managers, effective January 2020. This information triggered an expedited audit of the fishery’s MSC certification status, which is currently being undertaken by the conformity assessment body.”

State will open small Alaska cod fishery

January 10, 2020 — A small cod fishery will occur in Gulf of Alaska state waters (out to three miles) for 2020, putting to rest speculation that no cod would be coming out of the Gulf next year.

A catch quota of about 5.6 million pounds, down from 10.2 million pounds, will be split among five regions: Prince William Sound, Cook Inlet, Kodiak, Chignik, and the South Alaska Peninsula, with limitations on gear and staggered openers.

Scientists, Fishermen Team Up to Track Cod in Alaska’s Outermost Aleutian Islands

January 9, 2020 — SEAFOOD NEWS — Last winter scientists and Alaskan fishermen agreed to launch a pilot study to develop methods for tagging cod on active commercial fishing vessels in the Aleutian Island.

Satellite tags had never been used on Pacific cod. No one had recorded seasonal movements of cod in the Aleutian Islands. This was the first time industry, scientists, and the fishing community all took part in the research.

Marine Stewardship Council’s Certifier MRAG Americas Calls for Audit on Gulf of Alaska Cod

January 9, 2020 — SEAFOOD NEWS — The Marine Stewardship Council’s certifying agency for Gulf of Alaska Pacific cod, MRAG Americas of Florida, announced an expedited audit for the GOA Pcod based on the new stock assessment that resulted in the fishery’s 2020 closure last month.

“New information on stock status provided by NOAA Fisheries and decisions of the North Pacific Fisheries Management Council in December of 2019” is the basis for a desk-based audit covering Principle 1 (stock status) only, the MSC announcement reads.

Adak, Groundfish Trawlers at Odds on P-Cod Processing

December 18, 2019 — Pacific cod stocks hard hit by warming ocean temperatures are becoming a focal point at federal fisheries meetings, where harvesting sectors and processors fight over who gets to catch and process this versatile vitamin and protein packed white fish.

Stock assessments in the fall of 2019 put the population of P-cod in the Gulf of Alaska below the federal threshold that allows for commercial harvest, for the benefit of endangered Steller sea lions who rely on them as a food source.

The Gulf cod fishery was cancelled. The Bering Sea/Aleutian Islands TAC was cut from 24,319,000 metric tons in 2019 to 22,000 metric tons for 2020.

The lower quota is intensifying the race for fish, and a fight between the trawlers and the community of Adak, Alaska, over where that fish will be processed.

At the heart of the battle is Amendment 113 to the fishery management plan for BSAI groundfish. This amendment set aside a portion of the Aleutian Islands cod fishery TAC for harvest by vessels directed fishing for Aleutian Islands Pacific cod and delivering their catch for processing to a shoreside processor located on land in Adak. The 5,000 metric tons P-cod harvest set-aside was designed to provide the opportunity for vessels, Aleutian Islands shore plants and communities where Aleutian Islands shore plants are located to benefit from the P-cod fishery.

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.

Alaska Cod Fishery Closes And Industry Braces For Ripple Effect

December 9, 2019 — In an unprecedented response to historically low numbers of Pacific cod, the federal cod fishery in the Gulf of Alaska is closing for the 2020 season.

The decision, announced Friday, came as little surprise, but it’s the first time the fishery has closed due to concerns over low stock.

“We’re on the knife’s edge of this over-fished status,” North Pacific Fishery Management Council member Nicole Kimball said during talks in Anchorage.

It’s not over-fishing to blame for the die-off, but rather, climate change.

Warming ocean temperatures linked to climate change have wreaked havoc on a number of Alaska’s fisheries in recent years, decimating stocks and jeopardizing the livelihoods of fishermen and locals alike who rely on the industry.

A stock assessment this fall put Gulf cod populations at a historic low, with “next to no” new eggs, according to Steven Barbeaux, a research biologist with the National Oceanic and Atmospheric Administration, who authored the report. At their current numbers, cod are below the federal threshold that protects them as a food source for endangered steller sea lions. Once below that line, the total allowable catch goes to zero. In other words, the fishery shuts down.
