November 15, 2018 — The lobster industry in southern New England has been on the decline for decades. As waters warm, some lobster fishermen are adapting by switching their catch to Jonah crab, a crustacean once considered a trash species.
Mike Palombo is captain of a 72-foot lobster boat, but his main catch is crabs.
He leaves from the Sandwich Marina for three-day fishing trips, going out over 100 miles to haul traps in the Canyons. One day this fall, he and his crew returned with around 23,000 Jonah crab and 2,000 lobsters in big saltwater holding tanks. “It was a good trip, very productive,” he said.
Jonah crab are sturdy, hard-shelled creatures, with black-tipped claws. They’re about a pound apiece. You might not have heard of them, but Jonah crab are sustaining Southern New England fishermen left stranded by the decline of lobsters.
Tracy Pugh, a lobster biologist with the Massachusetts Division of Marine Fisheries, said there’s been a drop in the lobster population south of the Cape, in part because the water temperature is rising. “The Southern New England lobsters are experiencing the bad aspects of climate change,” she said, “because they’re already in the southern extent of their range.”
Pugh says the warmer water is causing the lobsters to experience physiological stress. It’s also bringing in new diseases that affect lobster, and an uptick in predators like black seabass and tautog.
