York, Maine startup turns invasive green crabs into popular restaurant fare
YORK, Maine — In his days as a York High School marine science teacher, Mike Masi would educate his students about green crabs and other invasive species in the Gulf of Maine. Nowadays, Masi and a former student catch green crabs and sell them as food to high end restaurants and bait to commercial fishermen.
Masi, a diver, fisherman and member of the York Shellfish Commission, and Sam Sewall, an eighth-generation lobsterman and Masi’s old student, are the co-founders of York-based Shell + Claw, a business devoted to the study and commercial harvesting of green crabs. The two founded the business in 2020 and have sold green crabs for the last three years, putting in long hours of work to further their knowledge of the crustacean’s impact on local marine life.
The state refers to green crabs as Maine’s “most destructive and costly invader.” The species arrived to Maine shores in the mid-1800s in ballast water from European ships and soon began damaging soft-shell clams and the local marine habitat through their predation.
One solution to help curb the crabs’ impact? Catch them, cook them and eat them, just as Shell + Claw’s co-founders do. Crabs caught in the York River are taken by Masi and Sewall, when they are molting, and sold to regional restaurants for their soft-shell crab meat while hard-shell green crabs can be purchased as bait.
“One of the things we’re really trying to do is diversify the options of working waterfront,” Masi said. “So many of our eggs are in the basket of lobster here in the state of Maine. It’s lobster or nothing in a lot of communities. So what happens if the lobsters continue moving offshore, continue moving more up the coast? What happens if regulations become too stringent? It could be a real hit to the working waterfront. Once you lose working waterfront, it’s not going to come back. Having diversity will add resiliency to the working waterfront here.”
In the winter, according to Masi and Sewall, the annual freeze usually kills off a chunk of the local green crab population. However, amid warmer winter temperatures in recent years, green crabs have been able to remain alive and active, feeding on soft-shell clams, tearing up eelgrass and eroding marshbanks as they excavate and scour for food.
A single green crab can consume upwards of 40 half-inch soft-shell clams in a day, according to the Gulf of Maine Institute.
The green crab invasion is apparent in the state’s statistics on soft-shell clam landings. In the mid-1970’s, Maine fishermen caught nearly 40 millions of pounds of soft-shell clams per year. But last year, fishermen caught approximately 5 million pounds of soft-shell clams in Maine waters.
Sewall was 8 years old when he received his commercial lobster license from the state. He’s seen the change in the local supply of soft-shell clams and the growing impact of green crabs.
“There’s no clams left in the York River,” he said. “Even when I was a kid, I remember being able to go out and dig a whole meal for the family in an hour.”
Among all commercial catch in Maine in 2023, just 3% of the total was attributed to soft-shell clams. The state’s report shows lobster made up 46% of all commercial catch in Maine last year. The entire year’s worth of commercial catch in Maine last year tallied almost 205 million pounds and totaled over $600 million in value, according to the state.
“Clams are historically a very, very important part of the coastal economy. We’ve seen that drop off significantly,” Masi said.
The Shell + Claw co-founders hope that other Maine fishermen, namely oyster farmers, could be interested in harvesting green crabs in the future to revive the soft-shell clam population and fill in a gap in the offseason for those fishermen.
Beginning on Earth Day next year – April 22, 2025 – Shell + Claw will launch a state-approved oyster and green crab farm in the York River, an experimental lease set to last for three years. There, Masi and Sewall hope to show more local fishermen the benefits of green crab harvesting and encourage them to follow suit while perfecting their own trapping processes.
“We think that green crabs could fill that little niche and be a supplementary income for interested oyster farmers that want to pull in a little bit more money in May and June,” Masi added.
But is the business of green crabs a profitable one?
Hard-shell green crabs trapped by Shell + Claw have been sold to a single buyer in Rhode Island, whose fishermen use the species as bait to catch channeled whelk, a predatory sea snail.
Dating back to 2022, Shell + Claw reports having sold 48,000 pounds of hard-shell crab. At $0.60 per pound, the York business has made just shy of $29,000 from bait sales alone. However, the bait market has at times been unreliable for Shell + Claw, as channeled whelk buyers in China have not always needed Rhode Island fishermen to go out and fish for the snails.
Shell + Claw has sold about 1,600 soft-shell green crabs each year to restaurants at around $3 per crab, resulting in nearly $5,000 in additional sales.
From what they hear from their customers, though, the more green crabs Shell + Claw can harvest and sell, the better.
“We could triple our production and probably not meet the demand, just from what we have right now,” Masi said. “The chefs have been great and they know that we’re in the research and development phase, but to become more of a business, we’ve got to be able to more consistently produce product.”
Shell + Claw sells soft-shell green crabs to four restaurants, according to the co-founders – Portsmouth, New Hampshire restaurants Black Trumpet bistro, Botanica Restaurant and Gin Bar and Row 34, in addition to Moeca in Cambridge, Massachusetts.
“It’s tough for a restaurant to not know what they’re going to get because they want to make a menu,” Sewall said. “Line cooks, if they get trained on something and then it’s gone the next day, it’s just a big waste of time. So we’ve got to be able to give them a steady supply for a month or two, whatever the season is, so they can have it that whole time.”
A goal of Masi and Sewall is to conduct outreach to people of southeast Asian descent living around New England, as Cambodian, Filipino and Vietnamese consumers have shown strong interest in Shell + Claw’s green crabs.
Seacoast chef says soft-shell green crab meat taste is sweet
Chef Jeremy Sewall, managing partner of the Row 34 seafood restaurants, was skeptical that green crabs would be deemed tasty enough to ever be appealing to diners. Now, he’s a green crab convert.
“Having spent a lot of time on the York RIver in Maine as a kid, they were kind of gross,” he said of green crabs. “They were in the mud and I thought they would taste muddy and a little earthy. They’ve actually got a nice sweetness to them. It’s a nice sweet crab meat.”
Sewall, a cousin of Sam Sewall, is a James Beard Foundation-nominated chef and received his training at the Culinary Institute of America. His career has taken him to London, Amsterdam and California before returning to his New England roots. Row 34, of which he’s a partner with Shore Gregory, has grown to include locations in Portsmouth, New Hampshire and three in Massachusetts, with restaurants in Boston, Burlington and Cambridge.
Jeremy Sewall and the Row 34 staff have been serving green crab at all four locations since the start of Shell + Claw’s harvesting efforts. The crustaceans have been served two ways by Row 34, either fried and served on a slider, or chopped up and served with seasonal vegetables in a pasta dish.
“They’re just really good. It’s another tasty seafood that I think New England has to offer,” Jeremy Sewall said.
Due to the bulk of harvesting being conducted in the spring and summer, Row 34 is not currently offering green crab on its menu. But the business will again in the future, continuing a partnership with Shell + Claw that is a first-of-its-kind initiative for the Row 34 brand.
Chefs at Row 34 have had to become innovative in preparing a menu with lesser-known fish due to the occasional shortage of more popular species.
“We’ve had to rely on other species from a seafood standpoint because the ones we tend to like, we’ve eaten all of them,” Jeremy Sewall said. “Eating a diversity of creatures out of the ocean is a great thing.”
But in the chef’s mind, for New England’s soft-shell clam population to boom once more, green crab harvesting and marketing efforts need to expand. It can’t just be up to seafood lovers to endlessly eat green crabs out of existence, he added.
“It’s got to go beyond restaurants to really make an impact on the green crab population,” Jeremy Sewall said. “You’re going to need to get it into the mainstream diet and in front of more consumers rather than (just at) a bunch of small restaurants around New England.”
Shell + Claw attemping to streamline their process
Another next step in Shell + Claw’s growth is to become more efficient in identifying green crabs that are about to molt. Rather than go through each crab one by one, Masi and Sewall hope to be able to locate green crabs that are about to transition into a softer shell just by looking into a trap or tray full of the crustaceans.
In the early days of their startup, Masi and Sewall would check on the pre-molt green crabs every 12 hours, sometimes trudging into the dark of night to observe their catch and separate the crabs.
“We’re putting a lot of man hours in when we’re actually sorting these every day between us and the interns,” Sewall stated. “If we’re going to make it a business, we have to pay these people and then make a little ourselves.”
While the number of green crabs in the Gulf of Maine is anecdotally high, Shell + Claw’s operation is still relatively small. The business has 30 green crab traps and a homemade “crab condos” where the captured about-to-molt crabs are placed before being sold to restaurants. By comparison, Sewall owns 800 lobster traps.
But amid the uncertainty of the soft-shell clam population, and state fishermen bringing in the lowest amount of lobster in 15 years in 2023, Masi and Sewall see green crab harvesting as a way forward for those trying to make a living on the docks.
“I think that those that are going to be successful in the working waterfront in the years to come are going to be the individuals that are nimble, that are willing to try new things,” Masi said.
Green crab bounty program in Massachusetts seen as crucial for soft-shell clamming industry
In Ipswich, Massachusetts, historically teeming with soft-shell clams, officials have initiated a town- and state-funded green crab bounty program that pays fishermen to catch and dispose of the crustaceans. The program pays a select group of fishermen $0.40 per pound of green crabs that they catch and remove from the water.
Last year alone, a total of 85,838 pounds of green crabs were trapped and taken out of Ipswich waters, according to town Shellfish Constable Matthew Bodwell. In turn, over $34,000 was paid to the fishermen that caught them, while thousands more pounds of green crabs were caught in the town outside of Ipswich’s program.
Green crabs are “the most dangerous threat to Ipswich shellfish populations,” Bodwell says, and taking them out is “essential to the future of our clamming industry.”
“Green crab trapping is a very important program that has been, and continues to be, effective in lowering overall green crab numbers,” he said. “This in turn allows more juvenile soft shell clams to grow to harvest size, protects the Great Marsh from the destructive burrowing of the crabs, and protects eel grass from being eaten by the crab. Trapping, in my opinion, is the best solution for sustaining clam populations and protecting our marshland.”
Back in York, Masi believes Shell + Claw’s unofficial study has had a mirroring effect in rejuvenating the soft-shell clam population in Braveboat Harbor.
By removing tens of thousands of pounds of green crabs themselves, slowly but surely, some soft-shell clams are living longer.
“I am seeing some inch-and-a-half-sized clams and those ones definitely settled within the time period that we’ve been working there and when we’ve been harvesting (for green crabs),” Masi said. “I think we are seeing that we’ve done some ecological good in trying to protect the clam resource.”

You drew a Maine moose permit. Here’s what to do right now.
For many hunters, drawing a Maine moose permit is a once-in-a-lifetime opportunity. After years — and sometimes decades — of applying, the excitement of seeing your name among the winners quickly turns into a new challenge: planning for the hunt.
Whether you’re going on your first moose hunt or preparing for another trip into the Maine woods, there are several important steps permit winners should take as soon as possible.
Hire a registered Maine guide
Many permit winners hire a registered Maine guide to help locate a moose, scout hunting areas and navigate unfamiliar country. You’re paying for their knowledge, experience and time spent scouting before the season ends. Even if you’re a Maine resident, hiring a guide should be a consideration. Most hunters don’t have the time to make multiple scouting trips, and trail cameras aren’t always an option because cell service is limited or nonexistent in many hunting areas.
If you’re considering hiring a guide, don’t wait too long. Available openings often fill up the night of the lottery.
Book lodging for your moose hunt
Sporting camps, cabins, campgrounds and hotels near popular moose hunting areas will also fill up quickly. If your hunt will take place hours from home, securing lodging should definitely be one of your first priorities. Waiting until summer will leave you with fewer options and a longer commute to your hunting area.
Find a meat processor
The state maintains an official list of moose meat processors. The last thing you want to be doing is calling around on a warm September day trying to find a butcher willing to take your moose. Processors can only handle so many animals each season, and much like guides and lodging, many fill their schedules quickly. Calling ahead and having a plan in place can save a lot of stress after a successful hunt.
Line up your hunting partners and helpers
If you’re not hunting with a guide, it’s helpful to know who will be accompanying you. Aside from sharing the experience, friends and family can help scout, call, spot animals, film the hunt and retrieve a harvested moose.
How will you retrieve the moose?
Depending on where the animal is harvested, you may need an ATV, side-by-side, trailer, winch, ropes or other equipment to retrieve it. Keep in mind that ATVs and side-by-sides are prohibited in the North Maine Woods, so you may need to quarter and pack the moose out instead. In that case, game bags, packs, knives and saws will be essential, while items such as a jet sled or game cart may help make the job easier.
Gather your moose hunting gear
In addition to your weapon, consider what you’ll need for the hunt itself. Tarps, coolers, headlamps, GPS units, an inReach, radios, rain gear and extra fuel can all make a hunt more comfortable and efficient.
If you’re planning on getting away from the roads, you may need or want a wall tent. You’ll also need cots or other sleeping gear, a heating source, water, cooking gear and emergency supplies. A spare tire, jumper cables, chainsaw and basic tools can also be invaluable when traveling remote logging roads.
Prepare for meat care and transportation
Make plans to have coolers, ice, transportation and storage well before opening day.
Sight in your rifle or practice with your bow
Don’t be the hunter who misses because their scope was 8 inches off, got bumped during travel or hasn’t been checked since last season. Confirm your rifle is properly sighted in before the hunt, and shoot again after arriving in camp. Stock up on ammo and spend time practicing from realistic field positions.
Don’t overlook shooting sticks, either. Many hunters regret leaving them behind. Shot opportunities are often farther than expected, and a stable rest can make all the difference when anticipation and excitement start to take over.
The same applies if you choose to bring a bow. Reps, shooting from different positions and accurately judging distance can all improve your chance of success.
Scout your zone
If you don’t hire a guide, make sure you’re familiar with your hunting area. Not only will you likely run into other hunters during the week, you may arrive at your preferred spot only to find another truck already parked there. Having backup options is key.
Conditions also vary dramatically from year to year, so what worked for hunters last season may not work this fall.
Depending on the weather, moose may be farther away from roads, requiring hunters to do more walking. Last September’s hunt saw lower success rates in every wildlife management district compared to 2024.
Moose biologist Lee Kantar noted that drought conditions and slightly earlier September dates can lead to changes in moose behavior. Drought and warm weather likely affect moose movement, feeding patterns and activity levels, resulting in moose staying closer to areas with moisture and green vegetation.
“If bulls are not widely searching for cows, if bulls and cows are bedding or ruminating more in dark growth during the day, and if hunters do not adjust and ‘go in after them’, then success will drop,” Kantar said
The same challenges can affect October hunts.
Study maps, use onX, review aerial imagery and learn access roads before the season begins. Many logging roads shown on maps are no longer passable or have been blocked off.
Prepare physically for the hunt
Even hunters who plan to hunt from roads may end up walking several miles in a day.
Just getting into a producing moose area can require long walks down logging roads, skid trails or old cuts. Moose hunting can be physically demanding, with long days outdoors, rough terrain, bugs and heavy lifting. Spending a few months improving your fitness can make the experience more enjoyable.
Create a checklist
Make a list of everything you’ll need including licenses, permits, firearms, ammo, retrieval equipment, coolers, camping gear, food, water and emergency supplies. The more organized you are, the smoother the hunt is likely to be.

Two charged with assault after boater dies overboard in Hurricane Sound
VINALHAVEN, Maine (WGME) — Two boaters are charged and a third is dead after he went overboard in Downeast Maine.
Just before 5 Thursday, Maine Marine Patrol says a boater fell overboard in “Hurricane Sound” near Vinalhaven.
He’s identified as 57-year-old Marshal Ames.
Marine Patrol says before they arrived, a good Samaritan from Hurricane Island was able to reach Ames and began CPR, but he was pronounced dead by first responders.
Officers say when the other crewmembers arrived on shore, they got into a fight with them.
The crew members, 39-year-old Geoffrey Barrett and 27-year-old Theodore Lane, are facing charges including assault.
The Maine State Police major crimes unit is now part of the investigation.

Local control is holding education back in Maine | Opinion
Scott A. Harrison, Ed.D., M.B.A., is a senior advisor at The Harrison Group, a consultancy based in Yarmouth.
Maine has long valued local control in education. That tradition reflects an important belief that communities should have a strong voice in shaping their schools. But local control should not prevent us from asking a harder question: Are there core functions that could be delivered more effectively through a single statewide framework?
One of the most important is educator evaluation and professional growth. Maine law already recognizes the importance of this work. Under Title 20-A, Chapter 508 (Educator Effectiveness), districts must implement performance evaluation and professional
growth systems that evaluate educators, assign effectiveness ratings and support
professional growth.
The law further requires superintendents to use those ratings to inform key human capital decisions, including recruitment, hiring, induction, mentoring, professional development, compensation, assignment and dismissal. In short, educator evaluation is not intended to be a compliance exercise. It is intended to be a primary lever for the continual improvement of teaching and learning.
In 2012, LD 1858 sought to advance that vision by giving districts broad flexibility to design their own systems. Districts could choose instructional frameworks, establish measures of effectiveness and determine how evaluators would be trained and calibrated. The goal was to balance local autonomy with professional accountability.
More than a decade later, however, the evidence suggests that flexibility alone has not produced consistent results.
My research involving 130 educators across four Maine school districts found only modest perceptions of performance evaluation and professional growth systems’ effectiveness.
On a four-point scale, average ratings ranged from 2.48 to 2.99. While educators generally agreed that districts provide individualized growth plans and can differentiate levels of instructional effectiveness, they rated several critical implementation areas notably lower, including instructional coaching, evaluator training, feedback quality, evaluator calibration and the use of evaluation data to inform professional learning and personnel decisions.
Although the sample was relatively small, the findings closely mirror what I have observed while working with predominantly rural Maine districts over the past decade.
The qualitative findings were equally revealing. Teachers and administrators described systems that are often cumbersome, inconsistently implemented and difficult to sustain. Educators reported spending significant time developing goals and documenting evidence, while administrators acknowledged that competing priorities frequently reduce evaluation to a compliance exercise rather than a meaningful opportunity for growth.
Participants cited insufficient training, inconsistent expectations, limited coaching support and weak connections between evaluation results and professional learning. Perhaps most significant, though not surprising given the realities of today’s schools, the primary obstacle appears to be not commitment, but capacity — the time, expertise and tools required to implement these complex systems with fidelity.
Designing and sustaining high-quality evaluation systems requires expertise in instructional leadership, observation and feedback, adult learning, professional development, data use and evaluator calibration. While some districts have built this capacity, many — particularly smaller and rural systems — have not. Even where expertise exists, time remains a major barrier.
Effective evaluation depends on regular observation, coaching, feedback and calibration. Yet for principals balancing instructional leadership with the daily demands of running a school, carrying out these responsibilities consistently can be extraordinarily difficult.
As a result, Maine has effectively asked more than 250 districts to independently build and maintain highly complex educator effectiveness systems. The outcome is predictable: uneven quality and implementation, and variable impact on teaching and learning.
This raises an important policy question: Should every district continue to design, train, calibrate and maintain its own evaluation system, or would educators and students be better served by a common statewide framework supported by regional and state expertise?
A statewide approach would not eliminate local control. Districts would continue to make decisions about hiring, staffing, curriculum, budgeting and school improvement priorities. Instead, the state would provide shared infrastructure: a common instructional and evaluation framework, validated tools, evaluator training, calibration supports, professional learning resources and implementation assistance.
The benefits extend beyond evaluation. A common framework would create stronger alignment across Maine’s educator pipeline. Colleges and universities could align coursework, clinical experiences and assessments to the exact same standards used in schools while sharing responsibility for educator success beyond initial placement.
Preparation programs, districts and the state would become partners in a continuous system of educator development, creating mutual accountability for results and a stronger return on Maine’s investment in teacher preparation.
Such alignment matters. As systems thinker Peter Senge observed, people working within the same system tend to produce similar results. If we want more consistent outcomes for students, we must pay closer attention to the systems shaping educator practice.
A statewide approach would not eliminate local control. Districts would continue to make decisions about hiring, staffing, curriculum, budgeting and school improvement priorities.
A common framework would establish a shared language and clearer expectations throughout the career continuum. It would also make continuous improvement easier. Rather than asking hundreds of districts to independently revise complex systems, the state could evaluate implementation, refine practices, share lessons learned and respond to emerging research. Educators have experienced too many short-lived initiatives that consume considerable time and effort before fading away.
A coherent statewide system would provide greater stability and more meaningful long-term improvement. The question is not whether local control matters. It does. The question is whether every district should be expected to independently build and sustain complex systems that require specialized expertise, significant resources and ongoing refinement.
If Maine is serious about improving outcomes for students, it should rethink which functions are best managed locally and which are better supported through statewide infrastructure. Educator effectiveness is one example. There are likely others.
In a previous op-ed here, I argued that Maine should reconsider whether teacher compensation is best negotiated district by district. The same question applies here. When critical human capital systems are essential to student success, a coherent statewide framework may be better positioned to advance equity, efficiency and effectiveness while preserving local decision-making where it matters most.
The goal is not less local control, but a smarter balance between local autonomy and statewide support — one that strengthens schools and improves outcomes for every student, regardless of geography.
