June 19, 2025 — From Gulf of Maine draggers to deep-sea pair trawlers, the push to modernize New England’s trawl gear has met a familiar wall: cost.
Paul Nosworthy, owner of New England Marine Engineering and Supply Inc., knows the numbers better than most.
“The back end of a midwater trawl — just the codend — costs around $40,000,” said Nosworthy. “Then you’ve got the sweep, the ground cables, the head section. All of that adds up. It’s not cheap gear.”
In a region where fuel efficiency is directly tied to profit margins, interest in lower-resistance nets, knotless twine, and semi-pelagic doors has grown, but Nosworthy said sticker shock still leads the conversation. “The technology has changed some,” he said, “There are new door designs depending on the fishery — midwater and otter trawls — but if you want to talk about what really works and what doesn’t, we’d need to ask the net-making companies.”
For now, fishermen are hesitant to gamble on new gear without proof that it will pay off. That hesitation, said Nosworthy, is rooted in survival. “It’s all about the cost. Gear on the bottom has a short life and a high cost to build and maintain,” he said. “And regulations are always changing — mesh sizes, chafing gear limits, you name it. Guys are less willing to try new stuff when the rules could change next year.”
He’s not wrong. In 2023 to 2024, five researchers with deep roots in the U.S. commercial fishing industry joined forces through the Fishery Friendly Climate Action Campaign to establish an evidence-based framework for fishing industry-led advocacy aimed at fostering a transition to a low-carbon fishing fleet. They evaluated emissions-reduction programs like the EPA’s Diesel Emissions Reduction Act (DERA) andCalifornia’s Carl Moyer Program, which underscore the high financial bar for commercial fishermen. According to the DERA report, the average cost of upgrading even a single engine on a fishing vessel is tens of thousands of dollars. While grants have made a difference, they haven’t erased the problem. Though these programs offer opportunities for some commercial fishermen, the programs and grants mainly focus on reducing air pollution, but do not cover all the technology and equipment that could lead to a low carbon fishing fleet.
