YORK, Maine — <\/span>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.<\/p>\n The trick is to identify invasive European green crabs<\/a> 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 \u2014 Masi can get $3 a crab at market compared to as little as 8 cents for a hard shell \u2014 but catching them provides a service of sorts to the ocean’s ecosystem.<\/p>\n \u201cJust about everyone hates them and we\u2019re trying to turn them into a premium seafood product,\u201d said Masi, whose company, shell+claw, is the only one that commercially cultivates these crabs.<\/p>\n 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<\/a>.<\/p>\n 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.<\/p>\n Chad Coffin, a clam fisherman from Maine, blamed a dramatic decline in his catch on the emergence of green crabs. Soft-shell clam landings have gone from 7.8 million meat pounds in 1978 to 1.3 million pounds in 2025, according to the state.<\/p>\n Green crabs, known for their brown or green shells and five spines on either side of their eyes, have taken advantage of warming ocean waters, a result of climate change that’s driven mostly by the release of greenhouse gases when coal, oil and gas are burned. The crabs are able to survive New England winters while also thriving in a range of diverse habitats. They eat almost anything and produce plenty of young; a female will release up to 185,000 eggs once or twice a year.<\/p>\n These traits have made them among the world\u2019s most successful invasive species, expanding along the West Coast<\/a> and into Alaska and reaching South Africa, Japan, Argentina and Australia.<\/p>\n \u201cThey\u2019re really pretty resilient little guys,\u201d said Carolyn Tepolt, an evolutionary biologist at Woods Hole Oceanographic Institution who has studied green crabs for two decades and uses them to understand why some species thrive in different environments.<\/p>\n For the past decade, the region\u2019s campaign to combat the crab invasion has been a grassroots affair that has had minimal impact on their numbers.<\/p>\n While a growing list of restaurants and seafood businesses are offering green crab, there are very few New England fishermen catching the crabs and almost no infrastructure to process the catch and get them to market. There isn’t even enough data to show how many crabs a fishery in New England could support, though experts say capacity is far higher than currently being caught.<\/p>\n Marissa McMahan, vice president of fisheries at Manomet Conservation Sciences, says that people in Washington County, Maine, on the Canadian border, tell her they can catch \u201cas many green crabs as you could ever possibly want.\u201d<\/p>\n \u201cBut they can\u2019t get them on a truck and get them to where they need to actually be, and often that\u2019s Boston or New Bedford or New York City,\u201d she said. \u201cThat is a huge impediment.\u201d<\/p>\n Small steps have been taken. Rhode Island passed a law that offers a green crab fishing license for just $10, Connecticut now allows crabs to be sold to restaurants without extra permitting, and Maine made it easier to get the crabs to market.<\/p>\n The problem, many advocates say, is the absence of significant government support in New England. Only Massachusetts offers incentives to catch them: Fishermen receive 40 cents per pound on top of what they get selling them, up to $100,000 per year. <\/p>\n Meanwhile, Washington state<\/a> declared an emergency in 2022 and expects to spend more than $38 million in state and federal funds through fiscal year 2027 eradicating the crabs. So far this year, nearly 2 million crabs have been caught and mostly converted into 135,000 pounds of waste that goes to an organic fertilizer company. The Shoalwater Bay Indian Tribe and Lummi Nation also catch crabs and use them as compost.<\/p>\n \u201cWe\u2019ve got treaty-protected fisheries at risk and critical habitats that are used by all sorts of native species, so we\u2019re really worried that we\u2019ll start to see those types of effects that they saw on the East Coast if we let the population get established,\u201d said Raquel Crosier, the deputy director of the state\u2019s Fish Program.<\/p>\n The good news in New England is that there is a growing appetite for green crab.<\/p>\n Since 2021, advocates have seen a more than 10-fold increase in restaurants offering crab. Some are putting fried green crab in sandwiches, on top of pasta dishes and in their sauces. Many take part in green crab weeks that happen during the roughly two-month softshell season.<\/p>\n PAGU, a Spanish Japanese tapas restaurant in Cambridge, Massachusetts, puts the crustaceans into the broth of its green crab laksa, a Malaysian-inspired noodle soup, and, when available, puts a tempura-fried soft-shell green crab inside a steamed bun called bao.<\/p>\n \u201cThese crabs are way more potent in terms of flavor,\u201d said PAGU’s chef and owner Tracy Chang.<\/p>\n Comparing them to king, stone or Jonah crabs, she added: \u201cThose all have just kind of like a sweet light crab flavor and this has like a really rich deep like luscious crab flavor.\u201d<\/p>\n Sitting in the crowded restaurant, Dr. William Li, a physician and author, took his first bite from his bao. Tangy, sweet and crunchy with its claws sticking out, the dish caught Li’s attention because he loves crab.<\/p>\n \u201cThis is kind of like a bite-sized treat to elevate your health,\u201d Li said. \u201cThis green crab bao was spectacular, filled with flavor, easy to eat, and very tasty.\u201d<\/p>\n Back out on the water with Masi, however, it feels like industrial-scale green crabbing is a long way off.<\/p>\n Masi’s system is labor intensive: His crew picks through thousands of green crabs by hand to spot those about to molt. Caught in the wild, the crabs are stored out on the water. Once they show signs of molting or busting, the crabs are relocated into a network of tubes in lobster crates.<\/p>\n Masi’s business has grown since he began five years ago, but he says it still feels like a hobby that brings in up to $20,000 annually. He remains bullish on a green crab fishery, talking of one day getting a bigger boat and improving efficiency. His inspiration is a centuries-old fishery in Venice, where green crabs, which are native there, are caught by families and fried to make a dish called moeche, among other delicacies.<\/p>\n \u201cI am cautiously optimistic about the potential for green crabs,\u201d Masi said. \u201cWe are one breakthrough from making this a profitable business.\u201d<\/p>\n ___<\/p>\n The Associated Press\u2019 climate and environmental coverage receives financial support from multiple private foundations.
