Maine’s lobster industry is grappling with soaring fuel costs and multiple challenges that threaten its long-term viability, industry participants say. Lobstermen such as Steve Train, who operates a 36-foot boat out of Casco Bay near Portland, report that rising diesel prices and other expenses are cutting deeply into profits ahead of the upcoming U.S. midterm elections.

Train, 59, estimates that fueling his vessel now costs approximately $6.49 per gallon—an increase of nearly 45 percent compared to last year. Additional expenses include bait costs as high as $260 per drum, alongside growing fees for berthing, insurance, and maintenance. He said these unpredictable and escalating costs make it difficult for operators to plan their businesses with confidence. Despite these strains, Train remains supportive of Senator Susan Collins, a Republican from Maine, citing her longstanding backing of maritime workers, even as he criticizes President Donald Trump’s tariff and trade policies as detrimental to the industry.

The sector also faces ecological and regulatory pressures. Efforts to protect endangered North Atlantic right whales, which migrate through lobster fishing areas along the East Coast, have led to proposed restrictions designed to reduce entanglements caused by ropes connecting lobster traps to surface buoys. Recent legislative action in the U.S. House of Representatives sought to delay implementation of these measures until 2035, but if the Senate rejects this freeze, stricter rules could have significant operational and economic impacts on Maine lobstermen.

Economic data from the Maine Department of Marine Resources highlights a drop in the state’s lobster harvest to 78.8 million pounds in 2025, down eight million pounds from the previous year. Despite the decline, lobster remains a dominant contributor to the state’s fisheries revenue, accounting for nearly 75 percent of its value. Alexa Dayton, executive director of the Maine Center for Coastal Fisheries, noted that the town of Stonington, Maine’s busiest lobster port, lands around 11 million pounds annually, generating approximately $50 million for the local economy from 350 boats. However, she cautioned that rising costs combined with historically low lobster prices have strained profits, causing some fishermen to question the sustainability of their livelihoods.

Researchers have linked these challenges in part to environmental changes. Damian Brady, director of the Darling Marine Center at the University of Maine, explained that while the lobster population peaked in 2008 due to favorable conditions, catches have steadily declined since then. Brady and others point to climate change as a key factor, with the Gulf of Maine experiencing warming at nearly three times the global ocean average since 1982. This warming has compressed the lobster "sweet spot," forcing fishermen to venture farther offshore in larger vessels, consuming more fuel and requiring additional crew.

Comparisons with neighboring Canada underscore the impact of regional temperature differences on lobster populations. Canadian lobster landings remain relatively robust as their waters have not warmed as significantly. As a result, Maine’s fishermen face increased operational costs and environmental challenges amid shifting lobster distributions.

The convergence of economic, ecological, and regulatory factors poses a complex threat to Maine’s lobster industry, a cornerstone of the state’s coastal heritage and economy. With ongoing debates over whale conservation measures and evolving environmental conditions, the industry’s future remains uncertain.
