August 9, 2021 — New research from Oregon State University recently published in the Marine Ecology Progress Series indicates climate conditions have a significant impact on Antarctic krill reproductive success.
Because krill is such an important component of healthy ecosystems, the impacts of krill abundance be far-reaching, the study found.
August 9, 2021 — The following was released by the Mid-Atlantic Fishery Management Council:
On the East Coast of the United States, some species of fish are already experiencing climate-related shifts in distribution, abundance, and productivity. Although the future is uncertain, a continuation or acceleration of climate change has the potential to strain our existing fishery management system and alter the way fishermen, scientists, and the public interact with the marine environment.
In order to begin preparing for this possibility, management bodies along the entire Atlantic seaboard have teamed up to launch a new project called East Coast Climate Change Scenario Planning. Scenario planning is a way of exploring how fishery management may need to evolve over the next few decades in response to climate change. You can find additional details in the introductory brochure.
Weigh In! Stakeholder Input is Key to Effective Scenario Planning
The initiative is being organized by a Core Team of representatives from the New England, Mid-Atlantic, and South Atlantic Fishery Management Councils, the Atlantic States Marine Fisheries Commission, and NOAA Fisheries. The team has lined up three kick-off webinars:
Please register at the links above. The webinars will introduce stakeholders to the overall initiative, explain the benefits of participating in the process, outline additional ways to become involved, and begin collecting stakeholder input.
An online questionnaire will be available soon to serve as an additional tool to collect input. Watch the Scenario Planning webpage for updates.
August 9, 2021 — For generations, winter flounder was one of the most important fish in Rhode Island waters. Longtime recreational fisherman Rich Hittinger recalled taking his kids fishing in the 1980s, dropping anchor, letting their lines sink to the bottom, waiting about half an hour and then filling their fishing cooler with the oval-shaped, right-eyed flatfish.
Now, four decades later, once-abundant winter flounder is difficult to find. The harvesting or possession of the fish is prohibited in much of Narragansett Bay and in Point Judith and Potter ponds. Anglers must return the ones they accidentally catch to the sea.
Overfishing is easily blamed, and the industry certainly bears responsibility, as does consumer demand. But winter flounder’s local extinction isn’t simply the result of overfishing. Sure, it played a factor, but the reasons are complicated, from habitat loss, pollution and energy production — i.e., the former Brayton Point Power Station in Somerset, Mass., pre-cooling towers, when the since-shuttered facility took in about a billion gallons of water daily from Mount Hope Bay and discharged it at more than 90 degrees Fahrenheit.
August 6, 2021 — An international agreement to protect the fisheries of the central Arctic region, signed in 2018, went into effect 25 June.
The agreement was signed by nine countries and the European Union. Signatories include Arctic countries – the United States, Canada, Russia, Denmark, and Norway – and countries with fishing interests there, including China, Japan, South Korea, and Iceland.
August 5, 2021 — NOAA announced on Tuesday, 3 August that its scientists have determined the size of this year’s “dead zone” in the Gulf of Mexico to be more than 6,300 square miles, a figure that’s both above the recent average and well above what officials initially forecasted in June.
The “dead zone” is term applied to the hypoxic zone that is annually established in the Gulf of Mexico. Fed by agricultural runoff, the Mississippi River dumps nutrient-rich water into the gulf, leading to algae growth during the spring and summer months. As that dies and sinks to the bottom, bacteria decay the algae but also consume oxygen in the process, resulting in an area of the ocean that is considered unsustainable for marine life.
August 4, 2021 — The National Oceanic and Atmospheric Administration (NOAA) is warning that the Gulf of Mexico’s “dead zone” is larger than average, with about 4 million acres of water potentially uninhabitable to fish and other marine life.
The agency said in a Tuesday report that for the past five years, the average hypoxic zone, or area with little to no oxygen where marine life easily dies, has been 5,380 square miles.
In 2021, this area is about 6,334 square miles, about 2.8 times larger than the 2035 target set by the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force, better known as the Hypoxia Task Force.
August 3, 2021 — Chinook salmon runs are in decline across Alaska, and research suggests a host of factors are to blame, from ocean predators to warmer streams and excess rain. But Alaska Congressman Don Young recently added a novel suspect to the list: nuclear submarines.
“We have to figure this out. Have to work on it and make sure there’s not something going on,” he said of the poor runs. “Is it climate change? Are they moving north? Is there a nuclear sub stuck out there somewhere?”
Young spoke at a subcommittee hearing Thursday, and acknowledged his theory sounds unusual.
“Everybody laughs at me but at one time I counted 64 nuclear subs from Russia,” he said. “We kept track of them as they came off the coast of California.”
A spokesman said Young was referring to matters like those described in a 2020 BBC article on radioactive submarine wrecks.

August 2, 2021 — New research from Rutgers University has investigated community and fisher strategies for adapting to stocks changing as a result of ocean warming.
The paper, “Not All Those Who Wander Are Lost – Responses of Fishers’ Communities to Shifts in the Distribution and Abundance of Fish,” focused on the groundfish trawl fishery in Northeast U.S., an area that is already seeing warming temperatures and is considered a hotspot for the effects of global warming.
August 2, 2021 — A heat wave that sent temperatures into the triple digits for three days in the U.S. Pacific Northwest in late June and early July drove up levels of the vibrio bacteria in area oysters, causing record numbers of illnesses from the bacteria and prompting oyster recalls.
The Washington State Department of Health (DOH) reported 75 lab-confirmed cases of vibriosis as of Wednesday, 29 July, and said there are likely many unreported cases. According to figures provided by DOH, the previous record number of vibriosos cases through 28 July was 48 in 2018.
August 2, 2021 — Small Pacific Island states depend on their commercial fisheries for food supplies and economic health. But our new research shows climate change will dramatically alter tuna stocks in the tropical Pacific, with potentially severe consequences for the people who depend on them.
As climate change warms the waters of the Pacific, some tuna will be forced to migrate to the open ocean of the high seas, away from the jurisdiction of any country. The changes will affect three key tuna species: skipjack, yellowfin, and bigeye.
Pacific Island nations such as the Cook Islands and territories such as Tokelau charge foreign fishing operators to access their waters, and heavily depend on this revenue. Our research estimates the movement of tuna stocks will cause a fall in annual government revenue to some of these small island states of up to 17%.
This loss will hurt these developing economies, which need fisheries revenue to maintain essential services such as hospitals, roads and schools. The experience of Pacific Island states also bodes poorly for global climate justice more broadly.
