Saving Seafood

Reinforcing the diverse ways people access seafood can ensure healthy communities in the face of change

February 8, 2024 — As climate change affects the oceans, coastal communities—particularly those at the front lines of ocean warming and sea level rise—are facing pressures that could threaten their access to aquatic foods.

“Climate change and other economic shocks are impacting how people access seafood, and typically households that are most reliant on seafood, such as those in Pacific Island countries, are most at risk,” said Jacob Eurich, a research associate at UC Santa Barbara’s Marine Science Institute, and a fisheries scientist at the Environmental Defense Fund. Which is why, he added, it is necessary to increase food system resilience in the area, which entails—among other things—the ability to maintain high levels of seafood consumption.

Senators support fisheries in the face of climate change

Janurary 30, 2024 — U.S. Senators Chris Murphy (D-Conn.), Richard Blumenthal (D-Conn.), and Elizabeth Warren (D-Mass.) introduced legislation to modernize outdated regulations governing commercial fishing along the Atlantic Coast. Even with fish locations changing drastically in response to warming ocean temperatures, the restrictions on species and the number of fish caught in Atlantic waters have not been updated in decades.

According to the release, commercial fishermen have been forced to travel further distances to access fish populations and are often forced to throw landings back, which results in higher mortality rates. The Supporting Healthy Interstate Fisheries in Transition Act (SHIFT) will require the Department of Commerce to consider changing geographic ranges of fish populations as it oversees federal fishery management plans and quota allocations for Atlantic states.

Senator Murphy of Connecticut has focused on job creation within his state, and in May 2023, he was a proponent of increasing federal and state spending on the cleanup of Long Island Sound to help restore commercial and recreational fishing in the state. Murphy also helped increase federal funding for aquaculture to $19 million in 2023.

NEW JERSEY: Fish mortalities up in New Jersey waters due to low oxygen levels

January 26, 2024 — Dead fish, lobster, and crab were found in the ocean off the U.S. state of New Jersey in the summer of 2023, and the suspected cause of death was low oxygen and pH levels, according to a report by Rutgers University researchers.

Lower dissolved oxygen levels alone are not uncommon in summer months, as they are a natural part of the seasonal stratification of warmer and cooler waters off the U.S. Mid-Atlantic, but 2023 was notable for both lower than usual oxygen and a drop in pH – the measure of relative acidity in the water – the study found.

Canada lags behind on efforts to address human rights abuses in seafood supply chains

January 26, 2024 — Seafood has become a source of concern for consumers who pay attention to the environmental and social impacts of what they buy. Climate change is adversely affecting ocean ecosystems, and a series of widely publicized scandals have exposed widespread illegal fishing and awful working conditions in both fishing and seafood processing.

Seafarers in fishing often work 18 hours a day in what is widely considered to be the world’s most dangerous profession. Many are at sea for months or even years at a time, and most have no access to Wi-Fi. They are often excluded from labour laws and all are paid very low wages, despite producing food for high-income consumers.

Similarly, those working in seafood processing are also poorly paid, and many are migrant workers who lack basic labor rights.

In response to these concerns, governments in many seafood importing countries have taken action. The European Union and Japanese government have banned imports of seafood produced by illegal fishing, while the United States’ program to ban imports produced by forced labour includes seafood.

Climate change could critically harm $253 billion US fishing industry, experts tell senators

January 25, 2024 — Climate change has caused ocean temperatures to steadily rise, which, experts warned senators Wednesday, could significantly harm the fishing industry.

Andrea Dutton, a professor at the University of Wisconsin–Madison, said burning fossil fuels primarily drives climate change, which could cause widespread economic and environmental problems.

Fossil fuels generate high levels of carbon dioxide, which, in oceans, could cause heat waves and create acidic seawater that could harm anything living in the ecosystem.

Rashid Sumaila, a University Killam professor and research chair at the University of British Columbia’s Institute for the Oceans and Fisheries, said fisheries catch about 120 million tons of fish annually, generating about $240 billion in worldwide revenue.

Seafood industry well-positioned to meet challenges of climate change

January 25, 2024 — Climate change is undeniably having an impact on where certain seafood species are located, and its exact effects are still being researched.

Research being done in how stocks are shifting varies. Some NOAA studies have predicted high-value groundfish species will migrate toward deeper offshore waters on the west coast of the U.S., while others are pointing out the risks it poses to global blue food production. Despite those risks, a panel covering seafood sourcing amid climate change at the Global Seafood Market Conference – which ran from 23 to 25 January in Orlando, Florida, U.S.A. – said the seafood industry can meet the challenges and even weather them better than other protein industries.

Marine heat waves found to trigger shift in hatch dates and early growth of Pacific cod

January 24, 2024 — Marine heat waves appear to trigger earlier reproduction, high mortality in early life stages and fewer surviving juvenile Pacific cod in the Gulf of Alaska, a new study from Oregon State University shows.

These changes in the hatch cycle and early growth patterns persisted in years following the , which could have implications for the future of Gulf of Alaska Pacific cod, an economically and culturally significant species, said Jessica Miller of OSU’s Coastal Oregon Marine Experiment Station at Hatfield Marine Science Center in Newport and the study’s senior author.

“We found that the  were hatching two to three weeks earlier. To see that dramatic of a shift in hatch dates of a species due to a one- or two-year event is pretty remarkable,” Miller said. “That those changes continue to persist suggests that marine  might be having long-lasting impacts that also influence the likely trajectory of the species under .”

MAINE: How the Maine coast will be reshaped by a rising Gulf of Maine

January 23, 2024 — Extreme weather made more frequent and ferocious by climate change has walloped Maine in the last year, and the coastal devastation wrought by recent storms is causing many Mainers to realize that climate change is happening right now.

From Kittery to Eastport, climate change came to life. Mainers could do little but watch as storms rushed in on seas elevated by climate change, buckling roads, scouring beaches and washing away our working waterfronts.

“People aren’t just waking up to climate change, but these storms have made theory into a pretty scary reality,” said Hannah Pingree, co-chair of the Maine Climate Council. “People thought we’d have more time to change, to prepare. This was our wake-up call. We’re running out of time.”

Between the two storms that hit the coast on Jan. 10 and 13, and the Dec. 18 storm that wreaked at least $20 million in damage to 10 Maine counties, there’s almost no way a Mainer could have missed the impact of this extreme weather, which can be traced back to climate change.

Too little, too late: the desperate search for cod babies

January 23, 2024 — Guðrún Bjarnadóttir Bech sings to herself while she sorts through baby fish with a pair of tweezers. “Ding! Ding! Ding!” she suddenly bursts out. “That’s a plaice,” she says – her reaction testament to how few she sees.

It is 2021 and Bech is working onboard the Jákup Sverri, a Faroese marine research ship that’s trawling for juvenile fish around the Faroe Islands in the north Atlantic to assess the state of populations including haddock, sand eel and Norwegian pout.

But there is one juvenile the scientists onboard are desperate to find: cod. The babies are minute, each measuring between 2mm and 25mm (0.08in to 1in). The smaller the individual, the more difficult it is to distinguish between different species. But as cod grow, their eyes and heads get bigger, and their skin, though still quite transparent, turns grey-green.

Q&A: Growth rings in fish give clues about fluctuations in climate over decades

January 21, 2024 –A giant tree in your backyard can reveal stories about Earth’s past climate. The concentric rings in the trunk, besides indicating the age of the tree, also shed light on the corresponding weather conditions during each year of the tree’s life.

But  are not exclusive to trees. Similar rings found in the tiny ear bones of  provide clues about the effects of climate change on both land and sea.

Bryan Black, an associate professor of dendrochronology at the University of Arizona Laboratory of Tree-Ring Research, has been applying the tree-ring dating techniques to so-called “fish rings” to understand how environmental variability is affecting fish growth and productivity over decades.

In this Q&A, Black discusses the techniques he uses to study growth increments in the ear bones, or otoliths, of fish; the correlation between otoliths and climate change; and how the fish-ring dating technique is comparable to tree-ring dating.
