Maine's catch of lobster declines again as high costs and climate change impact industry

PORTLAND, Maine (AP) — Maine's catch of lobsters declined for the fourth straight year, state fishing regulators said Friday, as the industry continued to grapple with soaring business costs, inflation and a changing ocean.

The haul of lobsters, Maine's best known export and a key piece of the state's identity and culture, has declined every year since 2021, and some scientists have cited as a reason warming oceans that spur migration to Canadian waters.

The sector brought in 78.8 million pounds (35.7 million kilograms) of lobsters in 2025, down from more than 110 million pounds (49.9 million kilograms) in 2021, regulators said. It was the lowest total since 2008.

Inflation hit the industry hard last year, and there were more than 21,000 fewer fishing trips than in 2024, according to Carl Wilson, commissioner of the Maine Department of Marine Resources. Market uncertainty due to tariffs and a late start to the busy portion of the fishing season also played roles, he said.

“This combination of factors likely contributed to the decline from 2024 to 2025 in the lobster harvest of more than eight million pounds and a decrease in the overall value of more than $75 million,” Wilson said in a statement.

The vast majority of the country's lobsters are caught in waters off Maine, though they are also trapped elsewhere in New England.

The overall catch, among the most lucrative in the U.S., is frequently worth more than $500 million at the docks each year. Last year it was more than $461 million.

The southern New England lobster fishery has been declared depleted by regulators for years. That decline happened as waters warmed off Rhode Island and southern Massachusetts, and scientists have warned that the trend could be repeating off Maine. The crustaceans are sensitive to changes in temperature, particularly when young but also throughout their lives.

Last year the regulatory Atlantic States Marine Fisheries Commission said lobster populations have shown “rapid decline in abundance in recent years” in key areas and declared the species to be experiencing overfishing. Environmental groups have called for tighter regulation of the fishery.

Some members of the industry have pushed back on that assessment and say fishermen are already restricted by regulations meant to conserve the lobsters and save endangered whales.

Last year's catch was still relatively high compared with historic numbers, up from typically 50 million to 70 million pounds (about 23 million to 32 million kilograms) in the 2000s and even less in the decade before that.
