Saving Seafood

What lives, what dies? The role of science in the decision to cull seals to save cod

March 16, 2020 — Atlantic cod on the Grand Banks of Newfoundland supported one of the world’s greatest fisheries for over three centuries. Yet this seemingly inexhaustible resource is in bad shape. Some stocks are now endangered and their survival could depend on removing a key predator, the grey seal.

This raises some difficult questions: How do we determine the value of one species over another, and what is the role of science in this conundrum?

My colleagues and I in the Fisheries Economics Research Unit at the University of British Columbia are fascinated by these questions. As an interdisciplinary group of economists, ecologists and social scientists, we commonly attribute values to animals in different ways. But determining whether to kill one animal to preserve another is less straightforward.

The collapse of the Grand Banks fisheries is considered one of the most significant failures in the history of natural resource management — akin to the ongoing degradation of the Amazon — and casts a long shadow over Canadian fisheries management.

Scientists Collecting Data on Commercial Fish Species in Wind Energy Lease Areas

March 12, 2020 — The following was released by NOAA Fisheries:

NOAA Fisheries scientists and colleagues have started a three-year study of Atlantic cod and other commercial fish species in Southern New England. Their goal is to gather baseline data to address how offshore wind development in the region could affect these animals.

An autonomous underwater glider is surveying areas in and around Cox’s Ledge. This includes the South Fork wind energy lease area south of Rhode Island and Massachusetts. The glider has a hydrophone to detect fish spawning sounds and an acoustic telemetry receiver to detect tagged fish. The receiver will identify location and seasonal occurrence of hotspots for key commercial and federally listed fish species.

According to project lead Sofie Van Parijs, there is little information on Atlantic cod spawning specific to Southern New England waters. Cod elsewhere are known to form large, dense spawning aggregations in predictable locations relatively close to shore, where they can be vulnerable to disturbance that might affect spawning success. Van Parijs also heads the Passive Acoustics Research Group at the Northeast Fisheries Science Center laboratory in Woods Hole, Massachusetts.

“Biological sampling will determine the population’s onset of spawning and track growth, maturity, age structure, and other life history parameters,” Van Parijs said. “This information will help inform the starting date for our glider surveys each year. We will tentatively conduct these surveys from December through March this year and for longer periods in the subsequent two years.”

Conservation Law Foundation petitions to halt Northeast cod fishing

February 14, 2020 — Charging that New England fishery regulators are dominated by “deference to short-term economic interests,” the Conservation Law Foundation on Thursday filed a petition with the Department of Commerce seeking a halt to all directed fishing for Atlantic cod.

No fishing should be allowed until the New England Fishery Management Council and NMFS meet their legal obligation to end overfishing and rebuild the Georges Bank and Gulf of Maine cod stocks, the Boston-based environmental group says. Those steps should include 100 percent at-sea monitoring, area closures to protect spawning locations and habitat, and requiring selective groundfish gear, such as haddock separator trawls, the petition says.

The foundation wants a prohibition on directed commercial and recreational fishing using large area closures “once a stock’s incidental catch limit is caught.” The petition also calls for reducing “the incidental catch rate annually consistent with the current acceptable biological catch control rule until overfishing at sea is ended.”

 “Our regional managers have lost control of and abandoned the cod fishery,” said Peter Shelley, the foundation’s senior counsel, in announcing the petition.

“After decades of reckless decision-making, Atlantic cod populations are now in crisis,” said Shelley. “To give this iconic species a chance at survival and recovery, the federal government must take the strongest possible action today and temporarily prohibit further cod fishing.”

Fishing rules don’t match industry realities, advocates say

October 11, 2019 — The federal government on Wednesday released data showing that cod stocks in the area remain overfished and are not on target to be rebuilt by 2024. NOAA Fisheries also reported that “overfishing is occurring” among an already-depleted Gulf of Maine Atlantic cod population.

“Abundance is very low, not the way it used to be, so that’s obviously of great concern to us,” Division of Marine Fisheries Director David Pierce told the News Service after participating in “seafood day” activities Thursday to recognize the contributions of the fishing sector and the 90,000 jobs in the seafood industry.

Pierce said he had not yet reviewed the latest federal assessment, but said an industry-based survey and one in the works at the University of Massachusetts Dartmouth will also influence cod quotas for 2021 and 2022.

“It’s a very important assessment. A lot hinges on it,” Pierce said. “The health of the Gulf of Maine groundfish fishery is very dependent on the health of that Gulf of Maine cod stock.”

Calling the report “concerning,” Sen. Bruce Tarr, who represents the fishing port city of Gloucester, told the News Service, “I’m still reading through the details but I think it points to the fact that we should be doing things differently than we are today.”

NOAA: Overfished cod not on target to rebuild by 2024

October 10, 2019 — Cod stocks in the area remain overfished and are not on target to be rebuilt by 2024, according to new federal data. In its latest stock status for the Gulf of Maine Atlantic cod, NOAA Fisheries also reported that “overfishing is occurring” among an already-depleted population. The status is unchanged from NOAA’s 2017 assessment.

“The Gulf of Maine Atlantic cod shows a truncated size and age structure, consistent with a population experiencing high mortality,” researchers wrote in a 208-page report released Wednesday. “Additionally, there are only limited signs of incoming recruitment, continued low survey indices, and the current spatial distribution of the stock is considerably less than its historical range within the Gulf of Maine.”

The cod assessment is part of an operational assessment, updated through 2018, of 14 Northeast groundfish stocks by the Northeast Fisheries Science Center. Cod was identified as a stock that is experiencing overfishing, and the report categorizes eight groundfish stocks as having been overfished.

Canada’s ‘transformative’ fishing bill, C-68, heads to royal assent

June 19, 2019 — Canada’s Senate on Tuesday night passed C-68, a bill that amends the country’s more than 150-year-old core fishing legislation, to require rebuilding plans for depleted species populations among other important changes.

Just three of the country’s 105 senators voted against the measure, which now heads to the desk of governor-general Julie Payette for her signature, an act known as “royal assent”, bringing it almost immediately into effect.

“Today is a great day for our oceans. The overhauled Fisheries Act has the potential to be one of the most transformative things that has happened for our oceans in many years,” said Josh Laughren, executive director of Oceana Canada.

Just 34% (66 of 194 stocks) of commercial fish populations in Canada are healthy, while 13% (26 stocks) are critically depleted, only five of which have rebuilding plans (Atlantic cod in the Bay of Fundy/Scotian Shelf; boccaccio rockfish; two yelloweye rockfish groups and northern shrimp in fishing area 6, off the coast of Newfoundland and Labrador).

Cod Fishermen Upend Carveout for Alaskan Villages

March 22, 2019 — A federal judge cut the line Thursday on the government’s effort to promote sustainable cod-processing operations in a pair of Alaskan fishing villages.

Unveiled in 2016, the new scheme carved out a portion of the Pacific cod fishery off the coast of the Aleutian Islands to be used exclusively each year by vessels that planned to process their catch onshore rather than at sea.

Pacific cod, in contrast to the much-suffering Atlantic cod, is one of the most abundant and lucrative species of groundfish harvested in the region.

Without government intervention, however, the National Marine Fishery Service argued that the Aleutian fishing communities of Adak and Atka would catch less and less cod, and struggle to compete as centers for fish processing.

‘Three-fold competition’ arises for tighter cod supplies as tariffs could invert haddock price gap

January 18, 2019 — According to figures released at the National Fisheries Institute’s Global Seafood Market Conference, world cod supply is expected to decline to 1.5 million metric tons in 2019, down from 1.59 million metric tons in 2018.

Todd Clark, a founder and partner at Endeavor Seafood, an importer and marketer of frozen seafood based in Newport, Rhode Island, said that there’s a downward supply trend in both Atlantic cod, driven by reductions out of the Barents Sea, and Pacific cod, where US supply has fallen somewhat in the Bering Sea and sharply in the Gulf of Alaska.

“There’s a steady decrease in both of these resources, really,” Clark said.

Looking at Atlantic cod supply in historical perspective, the resource, at 1.3 million metric tons in 2017, has fluctuated between a low of under 1 million metric tons in 2007 and a 2.75 million metric ton high seen in 1974.

Catch Of The Day Or Tuna From A Test Tube? How Innovation Could Change Seafood

December 10, 2018 — Massachusetts is home to the nation’s top fishing port. More than $300 million in seafood lands in New Bedford every year.

But the kinds of seafood are changing.

Rising ocean temperatures are driving southern fish species into our coastal waters. Today’s there are strict catch limits on Massachusetts’ state fish, the Atlantic cod. Scallops are now the New Bedford fishing industry’s primary source of revenue.

In response, local researchers are developing artificial intelligence to promote smarter fishing. And private companies are working on alternatives — including bioengineered fish and even fish flesh grown in laboratories.

Acid threatens almighty cod

November 30, 2018 —Climate change could devastate a major northern hemisphere fishing industry, modelling finds.

For cod facing the effects of climate change, it’s not the heat but the acid that threatens.

Ocean acidification – caused by atmospheric carbon dioxide entering the water and lowering its pH value – means there’s a narrower thermal window for the success of two species of northern cod, meaning that one of the world’s largest fisheries will be threatened if global temperature increases are not limited to 1.5 degrees Celsius, a new study finds.

The researchers, led by Flemming Dahlke of the Alfred Wegener Institute in Germany, find that embryos of cod are able to survive only within a limited temperature range, and that the range lessens in more acidic conditions.

The researchers predict that Atlantic cod (Gadus morhuai) would be unable to spawn below the Arctic Circle by 2100 under a “business as usual” emissions scenario. The polar cod (Boreogadus saida) faces an even more perilous future, since it not only needs colder water, but also depends on ocean ice for its habitat.
