Dams give way to better habitat in Chesapeake Bay region

September 1, 2026 — A few years ago, biologist Brian Watson was looking for endangered mussels in Virginia’s Rock Island Creek when his assistant went around a bend and made a startling discovery. It wasn’t a rare mussel.

“There’s, like … a stone wall,” she shouted back to Watson. Then added, “That’s a dam.”

Standing 6 feet tall and stretching 55 feet across the creek, the dam was entirely unknown to them — appearing nowhere on maps or dam inventories.

But the dam wasn’t irrelevant to their project: It was taking a toll on mussels, as so many dams do. The biologists found shells of dead James River spinymussels, an endangered species, behind the structure.

“We assumed the mussels probably got washed down to the dam and then died as they got trapped,” said Watson, a mussel specialist for the Virginia Department of Wildlife Resources, noting that the sandy substrate and water depth behind the structure was unsuitable habitat.

It was one of more than 6,500 dams that dot more than 200,000 miles of waterways draining the Chesapeake Bay watershed. That’s an undercount. Many of them don’t appear on dam inventories. Research was required to learn that the one on Rock Island Creek was called the Baber’s Mill Dam, built in the early 1800s.

Large or small, dams create a host of problems. They alter habitat, block fish movement, change water temperatures, promote algal blooms and contribute to the decline of native species. Some are safety threats to people.

But the Baber’s Mill Dam no longer causes such problems.

By chance, an aquatic ecologist from the timber company Weyerhaeuser, which owned the property, contacted Watson about the dam a few months later. The state and company teamed up to remove the structure in April 2024.

Invasive green crabs are bad for the environment so New Englanders are starting to eat more of them

August 26, 2026 — As a morning fog lifted over Maine’s York River, Mike Masi and his two interns stood on a dock sorting through a mound of one of the region’s most despised crabs and hoped to find a few that would end up on a gastronome’s plate somewhere in New England.

The trick is to identify invasive European green crabs that are about to shed their hard shell, or molt, revealing a softer exterior that has the feel of a leather couch, and are popular at restaurants. Not only do these green crabs fetch more money — Masi can get $3 a crab at market compared to as little as 8 cents for a hard shell — but catching them provides a service of sorts to the ocean’s ecosystem.

“Just about everyone hates them and we’re trying to turn them into a premium seafood product,” said Masi, whose company, shell+claw, is the only one that commercially cultivates these crabs.

Masi, a 45-year-old former marine science teacher, is part of a growing movement across New England aiming to lessen the crabs’ destructive impact by developing new markets. Others are putting green crabs in pet treats, fish sauce and even a line of green crab whiskey in New Hampshire.

The green crabs, Carcinus maenas, made their way from Europe to the East Coast in the ballast waters of ships hundreds of years ago. Numbering in the tens of millions, they outcompete Atlantic rock crab and juvenile lobster, destroy eelgrass beds and undermine salt marsh banks. They also are costing the region’s shellfish industry tens of millions of dollars each year, as they eat mussels, oysters and soft-shell clams.

Opinion: Seabed mining would strip mine fishermens’ future

August 24, 2026 — As a family of lifelong commercial fishers, we’ve always done our best to take care of the ocean off Virginia’s coast. But right now, an out-of-state company wants to dig out the foundation of our fishing grounds.

The federal government is considering a recent proposal by a Florida-based mining company to dredge Virginia’s seabed. If granted, our entire Eastern shore – 2,500 square miles – could be opened up to mining that would tear up the ocean bottom and crush the marine life that depends on it.

The two of us have saltwater running through our veins.

As for me – Jim – I fell in the water when I was two and have been driving a skiff since I was eight. My great uncle was a crabber, and my great aunt was picking crabs. I always knew I wanted to be a commercial fisherman here – just fell in love with fishing.

And as for me – Katie – my neighbor in Freeport, Long Island, threw me in the water and told me to swim when I was three. At about nine, I’d take the neighbors’ dog out on a paddle boat at six am to grab mussels off the pylons and stay out until dark. Neighbors would tell my parents they’d seen me.

Today, we are Virginia’s largest harvesters of black sea bass and flounder, fishing over 100 trips per season. Jim, the tech whiz with a chemistry degree, recently designed and built our own boat and fishes all day with our 24-year-old son, Matt. Katie takes care of lobsters in the tank and delivers our product every Saturday to people’s houses. Around Chincoteague, some people know us better as “Jimmy Neutron” and “The Lobsta Lady.”

MAINE: Gratitude for our sea farmers

August 22, 2026 — Cultivating food for human consumption is among the most noble and important jobs in society. Harnessing the resources gifted to us by nature and turning them into delicious meals for our neighbors and visitors is a challenging task, and farmers—of both the land and sea—deserve our gratitude.

Our pristine waters produce the most exquisite seafood on the planet. The flavors of our farmed oysters, mussels, and salmon are desired by the finest chefs in America and envied by seafood producers all over the world. Maine’s sea farmers are the ones who make it possible for us to be nourished by this local, sustainable, and delicious food.

The Maine Farmed Seafood Coalition consists of over 50 businesses and industry support groups—including seafood farmers and dealers, banks, educational institutions, and nonprofits. Our goal is to tell the authentic stories of sea farmers and educate the public about the opportunities aquaculture presents for our economy, communities, and ecosystems.

CALIFORNIA: Proposed Marine Protected Area would restrict fishing near Morro Bay

July 9, 2026 — A Marine Protected Area (MPA) petition filed by the Santa Ynez Band of Chumash Indians (SYBCI) includes the area from Morro Rock to the dog beach.

The MPA was one of 20 received by the California Fish and Game Commission in 2023. There were also 72 proposed regulatory changes.

“The original petition proposed the allowance of recreational take of finfish and invertebrates except mussels and scallops,” said Claire Wagonner, California Department of Fish and Wildlife Marine Region Habitat Conservation Program Manager. “So it would’ve still continued to allow some recreational take.”

Waggoner said that changed in April when the tribe requested to amend the petition, allowing only tribal fishing for the SYBCI.

“It’s our livelihood,” said Lori French, a Morro Bay fisherman’s wife. “It’s his identity. It’s not like you just go to work and shut the job off.”

WASHINGTON: Washington state reclassifying golden mussels as a banned invasive species

April 27, 2026 — The U.S. state of Washington is taking emergency action to reclassify golden mussels as a Prohibited Level 1 invasive species following the discovery of the species in Oregon earlier in the month.

Originally from China and Southeast Asia, golden mussels are an invasive species in the U.S. that are known to cause damage to infrastructure and reduce water quality, harming local fishing operations. The species was first detected in California in 2024, but a second instance was detected in Oregon in April 2026. According to the Oregon Department of Fish and Wildlife (ODFW), a watercraft was intercepted at the Ashland Boat Inspection Station carrying golden mussels.

Cocaine Pollution Seems to Make Salmon Swim Farther Than Usual. Scientists Don’t Know the Long-Term Consequences

April 24, 2026 — The world’s waterways are becoming increasingly contaminated with pharmaceuticals and illegal drugs—and the pollutants are seeping into marine animals. Cocaine, specifically, has been found in sharks, shrimp, mussels and eels, but exactly how these human-derived contaminants might be affecting wildlife has remained mysterious.

Now, new research offers a first look at how cocaine can alter the behavior of fish in the wild. Young Atlantic salmon exposed to cocaine’s primary metabolite—the compound created when human bodies break down the drug, which gets excreted into wastewater—swam farther than their sober peers in a Swedish lake, researchers report in a study published April 20 in the journal Current Biology.

The findings affirm the need to “carefully understand and manage all of the diverse chemicals society uses that can end up in our waterways,” Mark Servos, an ecotoxicologist at the University of Waterloo in Canada who was not involved with the research, tells Science’s Erik Stokstad.

The scientists behind the new study visited an Atlantic salmon hatchery in southern Sweden, where they outfitted 105 two-year-old, captive-raised fish with tracking tags and slow-release capsule implants. In one-third of the group, the implants gradually released cocaine into the creatures’ bodies. In another third, the devices released cocaine’s main metabolite, benzoylecgonine. In the final third—the control group—the implants provided no chemical related to the drug.

Gulf of Maine sees rising pH, defying expectations of increasing ocean acidity

July 31, 2025 — The Gulf of Maine—home to commercial fisheries for oysters, clams and mussels—has unexpectedly avoided an increase in seawater acidity, helping to preserve the health of its fisheries.

“Contrary to expectation,” a team of scientists wrote in a paper published in the journal Scientific Reports, we … find that pH has increased (+ 0.2 pH units) over the past 40 years, despite concurrent rising atmospheric CO2.” (Determining the decades-long trend required measurements of boron isotopes within annual skeletal bands built by crustose coralline algae. More about that later.)

The Gulf’s acidity levels are unexpected because atmospheric levels of  continue to climb. And because carbon dioxide is absorbed faster and easier into , the frigid waters of the Gulf would be expected to take in more carbon. More carbon in water generally lowers pH and increases acidity.

“One goes down and the other goes up,” said Alan Wanamaker, an Iowa State University professor of earth, atmosphere, and climate and a paper co-author. “That’s what we’ve seen in the .”

Plenty of Space to Flex on Mussel Beach

February 10, 2025 — The presence of freshwater mussels is indicative of high water quality and a healthy ecosystem. Their absence tells a different story, and the latter is the more-familiar tale in southern New England. Their populations in this three-state region have been degraded by a long history of damming and pollution.

University of Rhode Island research associate Elizabeth Herron noted these overlooked creatures are a critical part of the region’s aquatic systems.

“They help reduce nutrients and algae by filtering out things. They can reduce things like bacteria, so they’re important,” said the program coordinator for URI Watershed Watch. “They’re an important food source. I have a dock on a pond, and I can tell you every spring, when we put the dock back out, there’s a giant pile of empty, freshwater mussel clams that the muskrats feasted on over the winter.”

These bivalves are sometimes called “livers of the river,” because they filter particles such as algae, E.coli, and fungi out of the water. They also provide habitat for other invertebrates and fish, and they deposit nutrients into the benthic layer for other creatures to eat.
