“It’s All About Momentum” - How The Massachusetts Oyster Project is Sustainably Enhancing Waterways


What is an oyster upweller?

“For change to happen, something has to be real and recognizable.”

Oyster shells are not trash
Another keystone program is recycling empty shells and putting them back in the water to create favorable environments for oyster reefs to grow.
“Shells are considered trash,” Erika says. “But the value they add when back in the water is huge.”
MOP has been recycling shells from restaurants across Cape Cod since 2021. After a year of drying and aging to kill any harmful bacteria, all the shells they collect in the buckets are ready to begin protecting and preserving our coastlines once again.
Restaurants can take pride in recycling their shells rather than sending them to landfills, giving customers confidence not only in where their food comes from but also in how it’s disposed of afterward.

Engaging the local community in Yarmouth
A great example of the programs in action can be found in Yarmouth, Massachusetts, where Shellfish Constable Casaundra Healy has collaborated with MOP to establish both oyster upwelling and shell recycling programs in the town.
Casaundra fell in love with aquaculture during a college internship and has now been working in the shellfish industry for seven years. As Yarmouth’s Shellfish Constable, she’s in charge of an area where fishing is “almost religion,” and people have “salt water in their veins.”
Alongside patrolling and ensuring strict compliance with fishing rules, Casaundra is also tasked with monitoring, protecting, and preserving Yarmouth’s national habitats.
“It comes down to sustainability,” she says. “If I see further decline anywhere, I will come up with ways to resolve it.”

The Yarmouth Upweller is one such solution, and Casaundra hopes it will grow 60,000 oysters to put back in the Bass River.
“We’re very proud to be running both programs,” Casaundra says. “Shellfish are a critical piece of the puzzle on how to get nature back in balance with itself.
“Our key focus is on improving water quality and bringing back the native population of shellfish that have declined over time.
“We’ve had a huge outpouring of support from the local community with multiple organizations and departments coming together.
“We rely on their insight to guide where changes can be implemented that will hopefully revert some of the critical endangerments before they get too extreme.”

One million oysters by 2030
The shell recycling program aims to collect over 75,000 pounds of shells in 2024 with the help of volunteers and local restaurants––and ultimately plant one million oysters by 2030. As momentum continues to grow, the hope is that more communities will start implementing MOP’s programs.
Erika concludes: “As we continue to expand and start more programs, I hope other cities will think: ‘If they can do it, why can’t we? What’s holding us back?’
“It’s all about momentum, and I think we can continue building it.”
