Can robots improve New England’s commercial fishery?

October 14, 2025 — Imagine a troller headed out to sea in search of its catch. Logbooks and experience tell the captain where to look. But ocean conditions are changing, and so is fish behavior. Historical knowledge is not as helpful as it once was.

Today’s fishermen need more information, according to Melissa Sanderson, Chief Operating Officer of the Cape Cod Commercial Fisherman’s Alliance.

“We’re looking primarily at salinity, dissolved oxygen, temperature and chlorophyll-a – so how much phytoplankton is in the water,” she explained. “And those correlate really well with what we think are going to be the environmental triggers for when fish change their behavior.”

Enter the robots. Yes, robots. It turns out robots could be the next tool in the toolbox for local commercial fishermen.

“So they’re about three feet long,” Sanderson said. “They’re sort of in the shape of a torpedo. And the fisherman can just toss them overboard when they get out to sea.”

The fishermen program the robots, tell them what data to collect, then get down to work.

“The fishermen just keep doing what they’re doing,” said Sanderson. “They’re hauling their gear. They’re catching their fish. And the robot will come back when it’s done with its assignment. And when it gets onboard they can have all of the data and they’ll know what the temperature and salinity and the other environmental variables are over in that area.”

Pier to Plate Brings Sustainably Harvested, ‘Under-Loved’ Fish to New England Diners

September 8, 2017 — Every summer, tourists flock to Chatham Pier on Cape Cod, Massachusetts to watch commercial fishermen unload their catch. And for hundreds of years, it was cod that fishermen hauled into Chatham’s storied harbor—and cod that gave this coastal region its name.

Today, however, it’s dogfish and skate the fishermen are hauling, as warming waters, prior bad management, and a host of other factors have made cod increasingly hard to find in New England’s Gulf of Maine.

The fishermen are paid pennies for their catch—literally 20 cents per pound for dogfish—and the majority of the fish is whisked off to markets in Europe and Asia, where higher demand fetches better prices.

Tired of telling Chatham Pier’s tourists, “You have to go to Europe!” when asked what their catch was and where it could be bought, a group of fisherman launched Pier to Plate, a Cape Cod effort to shift the market away from cod and toward the lesser-known species that are more readily available in the New England waters, says Nancy Civetta, a spokesperson for the Cape Cod Commercial Fisherman’s Alliance.

“Pier to Plate is a way for the public to support local fishermen,” said Civetta. “The truth is, what used to be the bread and butter for Cape fishermen has changed. Now it’s dogfish and skate.”

Launched this year, the initiative provides the fish for free to chefs at participating restaurants, an idea that came from the fishermen themselves. “We all sat around and brainstormed, and the fishermen said, ‘Just give it away for free,’” Civetta said, at least until the effort gets off the ground. “Chefs still need to experiment with the fish, but they’re not going to do it out of pocket.”

MASSACHUSETTS: Chatham Dogfish Goes To College

February 16, 2017 — Dogs are going to college and it’s not a case of affirmative action run amok. The Cape Cod Commercial Fisherman’s Alliance is spearheading a new program to get dogfish into university dining halls.

A new “from boat to campus” version of a fish-to-table program is putting the fish on the tables of some of America’s leading universities including Yale, UMass, and Ohio State.

UMass has already ordered thousands of pounds for this academic year, and Yale plans to feature spiny dogs for their next Thanksgiving feast.

Christopher Howland is director of purchasing for UMass. He says, “Supporting local and regional farmers and fishing communities is extremely important to our team at UMass Dining. We’re very excited to be able to feature local and sustainable dogfish on the menu. Our talented chefs have been able to develop creative recipes that our students love.”
