Saving Seafood

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.

Baby sharks grow up in New Jersey’s back bays. Climate change could threaten the nurseries

July 31, 2026 — New Jersey’s back bays, those lush wetlands that sit between the barrier island beach towns and the mainland, are home to unknown numbers of baby sharks that feast on the American eel, crabs and small fish that thrive in the coastal salt marshes. Giving birth to litters in those food-rich shallow waters like Little Egg Harbor is just about all the maternal care given to the shark pups by their mothers, who swim back out to the Atlantic Ocean soon afterwards.

The tiger shark, the sandbar shark and the smooth dogfish return each summer to the Jersey coast to give birth between June and July, utilizing the safety of shallow waters that are free from predators that would devour their newborns. Although the smooth dogfish can grow to 3 feet long, the babies are no larger than 12 inches at birth and litters range in size from four to 20 pups. The dogfish are benthic feeders, meaning they forage along the bottom of the marsh.

“We all have our favorite shore towns,” said Adrianna Zito-Livingston, an ecologist who works as the climate adaptation project manager for the New Jersey Nature Conservancy. “We come back year after year. The sharks are doing the same thing.”

The Nature Conservancy is working with Monmouth University to research the health of the salt marshes that have become eroded due to the impacts of climate change. As part of that work, researchers like Zito-Livingston are tagging the sharks with acoustic trackers that are then monitored by listening stations placed along the Jersey coast. She said the sharks provide a good indication of the health of the salt marshes.

“In a lot of ways, sharks are a canary in the coal mine,” she said. “They’re top predators and healthy sharks with a good distribution are indicative of healthy, diverse ecosystems.”
