Saving Seafood

Changes are coming to the Chesapeake Bay, thanks to climate change

December 31, 2025 — Warming temperatures and changing rainfall patterns are changing the Chesapeake Bay.

New kinds of fish are venturing to the bay and long-established species face challenges as their bodies respond to warmer temperatures and changing salinity — salt and ion levels — in bay waters, recent studies show.

“We know climate is warming, and so are the waters of the bay, and we’ve seen this in our own time,” said Mary C. Fabrizio, a professor of natural resources at the Virginia Institute of Marine Science.

“We need to look at all the processes in the body of the fish that are affected by temperature, things like growth, things like reproduction and feeding behaviors.” She said these include: “When do fish migrate up river to spawn, or when do fish return to the bay to feed? And how do fish use the bay as a nursery area?”

Conflicting Ocean Indicators Suggest Moderate Returns of Pacific Salmon

December 30, 2025 — Juvenile salmon encountered a mixed bag of ocean conditions off the West Coast in 2025, based on an annual analysis by NOAA Fisheries and Oregon State University researchers.

The researchers examine 16 ocean indicators, from temperature and salinity to the quantity and quality of food available to juvenile salmon during their first months in the ocean. That is a crucial period for young fish as they search for prey to grow big and fast enough to stay ahead of predators.

Researchers refined the indicators through years of monitoring. They help fish managers anticipate how many juvenile salmon will survive to grow large enough to be caught in fisheries or return to rivers as adults in the next few years. The insight can help shape fisheries worth millions of dollars to the coastal economy and ensure that recreational, commercial, and tribal fisheries continue at sustainable levels.

ALASKA: Alaska fisheries in 2025: turmoil, economic and environmental challenges and some bright spots

December 26, 2025 — For Alaska’s fishing industry and fishing-dependent communities, 2025 was a year of turmoil and uncertainty, much of it imposed by ideological pursuits from the new Trump administration.

The short-lived agency called the Department of Government Efficiency hacked away at federal funding for science across the board. The National Oceanic and Atmospheric Administration in particular was in its crosshairs; the Heritage Institute’s Project 2025 blueprint for the second Trump administration heaped scorn on NOAA, saying its National Weather Service, National Marine Fisheries Service and other agencies “form a colossal operation that has become one of the main drivers of the climate change alarm industry and, as such, is harmful to future U.S. prosperity.” The NMFS’ Alaska Fisheries Science Center, which does the bulk of the research on which fishery managers depend, was among the agencies that suffered deep budget and staffing cuts.

The prospect of more cuts is unsettling, some officials said. “I guess now we’re getting to a point that I’m getting really concerned and almost freaked out about how much data that we’re potentially losing that we’re used to having,” Anne Vanderhoeven, a member of the North Pacific Fishery Management Council, said on Dec. 4 during that body’s December meeting.

Ecosystem shifts, glacial flooding and ‘rusting rivers’ among Alaska impacts in Arctic report

December 18, 2025 — The National Oceanic and Atmospheric Administration issued its annual Arctic Report Card on Tuesday, which documents the way rising temperatures, diminished ice, thawing permafrost, melting glaciers and vegetation shifts are transforming the region and affecting its people. The agency has released the report for 20 years as a way to track changes in the Arctic, according to Yereth Rosen with the Alaska Beacon.

“The Arctic continues to warm faster than the global average, with the 10 years that comprise the last decade marking the 10 warmest years on record,” Steve Thur, NOAA’s acting administrator for oceanic and atmospheric research and the agency’s acting chief scientist, said at a news conference Tuesday.

The report card is a peer-reviewed collaboration of more than 100 scientists from 13 countries, with numerous coauthors from the University of Alaska Fairbanks. It was officially released at the American Geophysical Union’s annual meeting in New Orleans, where Thur and other officials held the news conference.

The report is the first under the second Trump administration, at a time when the federal government’s commitment to documenting Arctic climate change has diminished: The president has repeatedly called climate change a hoax and federal departments are cancelling climate change-related research and projects, as well as scrubbing climate information from public view.

Crab prices may rise during the holidays due to delayed season

December 18, 2025 — Delays in California’s Dungeness crab season are continuing to impact Humboldt County and other parts of Northern California as state wildlife officials conduct safety testing for domoic acid, a naturally occurring toxin that can accumulate in shellfish.

While much of Humboldt County remains closed to crabbing, the ripple effects of the delay are already being felt across the state. With local crab limited or unavailable in several regions, seafood markets are turning to out-of-state supply, driving prices higher during what is typically one of the busiest times of year.

The delays stem from elevated levels of domoic acid detected during preseason testing conducted by the California Department of Fish and Wildlife. Domoic acid is a neurotoxin produced by certain types of marine algae and can build up in shellfish under specific ocean conditions.

“Domoic acid is produced by a naturally occurring single-celled marine alga,” said Christy Juhasz, a senior environmental scientist specialist with the California Department of Fish and Wildlife’s Marine Region. “Under certain ocean conditions, that alga can proliferate and release this toxin into the water.”

Under directives from the Trump administration, NOAA no longer provides information that the National Snow and Ice Data Center once used to monitor sea ice and snow cover, for example. The Colorado-based center now relies on satellite information from the Japan Aerospace Exploration Agency for its sea ice reports, and it has reduced its analysis.

Chevron’s demise could snarl Trump environmental agenda

December 16, 2025 — A new slate of environmental rollbacks from the Trump administration are poised to serve as early tests of a recent Supreme Court ruling that limited federal agencies’ power to defend their rules against legal attack.

Over the last few weeks, EPA and the Interior Department have floated rescissions of protections for federal waters, vulnerable species and climate change.

Each proposal presents a dramatic change in position from earlier regulations, and in the absence of Chevron deference — which gave agencies the benefit of the doubt when statutes are unclear — the Trump administration will have to make the case that its approach is the best interpretation of federal law.

New England’s shrimp fishery to shut down for the long haul after years of decline

December 11, 2025 — Regulators voted Thursday to extend a shutdown preventing New England fishermen from catching shrimp, a historic industry that has recently fallen victim to warming oceans.

New England fishermen, especially those from Maine, used to catch millions of pounds of small pink shrimp in the winter, but the business has been under a fishing moratorium since 2014. Rising temperatures have created an inhospitable environment for the shrimp, and their population is too low to fish sustainably, scientists have said.

An arm of the regulatory Atlantic States Marine Fisheries Commission voted Thursday to shut down the fishery for at least another three years. Abundance of the shrimp remained “poor” this year despite slightly improved environmental conditions, the Atlantic States said in documents.

Snow Crab Collapse Linked to Energetic Limitations During a Marine Heatwave

December 8, 2025 — A new study addresses one of the largest mass mortality events in recent marine history—the abrupt collapse of the snow crab population in the eastern Bering Sea. The research team was led by NOAA Alaska Fisheries Science Center fishery biologist Erin Fedewa. They set out to identify potential factors driving the increased mortality, population collapse, and recovery potential of Bering Sea snow crab.

Erin and her team measured snow crab energy reserves during and after the 2018–2019 marine heatwave and population collapse. This approach is the first of its kind for Bering Sea crab stocks. Findings show that warmer conditions and high population density led to energetic limitations—likely causing the snow crab population collapse.

A New, Rapid Energetic Condition Metric for Fisheries Management

Poor energetic condition is a state in which crabs have low energy reserves. This can increase starvation and mortality risk, emphasizing the importance of monitoring the energetic condition of individuals in marine populations. Techniques used to monitor energy reserves in fish often rely on data collected rapidly during annual scientific surveys, such as the weight-at-size of individual fish.

However, snow crabs have exoskeletons; they molt as juveniles, which uses a lot of their energy stores. They require more sensitive techniques to detect energy reserves beyond simple length-weight measurements. These techniques are often time-intensive and costly. Scientists have not routinely monitored energetic condition in Bering Sea crab populations to date.

Europe’s Green Energy Rush Slashed Emissions—and Crippled the Economy

December 2, 2025 — European politicians pitched the continent’s green transition to voters as a win-win: Citizens would benefit from green jobs and cheap, abundant solar and wind energy alongside a sharp reduction in carbon emissions.

Nearly two decades on, the promise has largely proved costly for consumers and damaging for the economy.

Europe has succeeded in slashing carbon emissions more than any other region—by 30% from 2005 levels, compared with a 17% drop for the U.S. But along the way, the rush to renewables has helped drive up electricity prices in much of the continent.

Germany now has the highest domestic electricity prices in the developed world, while the U.K. has the highest industrial electricity rates, according to a basket of 28 major economies analyzed by the International Energy Agency. Italy isn’t far behind. Average electricity prices for heavy industries in the European Union remain roughly twice those in the U.S. and 50% above China. Energy prices have also grown more volatile as the share of renewables increased.
