The new regional shellfish hatchery taking shape in the Town of Islip just got another $6.5 million from Albany. Governor Kathy Hochul announced the additional state capital funding on Tuesday, October 20 after touring the town's existing hatchery with Islip Supervisor Angie Carpenter, bringing New York's total commitment to the project to $16.5 million.

The state first put $10 million behind the hatchery in June 2024. Construction costs have risen since then, and the new money is meant to carry the building through to completion rather than let it stall partway.

Why a hatchery matters to the bay

A shellfish hatchery is where oysters and clams begin: juvenile shellfish are raised in controlled conditions until they are large enough for farmers to plant in their underwater plots. Islip's current hatchery is one of only a few in New York where the state's shellfish farmers can buy that seed stock, and its output reaches well beyond the town line. By the state's count, the existing operation produces about 25 percent of all caged oysters harvested in New York.

It is also an aging facility, which is what the replacement is for. When the project was announced in 2024, the state projected the new hatchery would raise production from roughly 20 to 40 million juvenile clams and oysters a year to somewhere between 100 and 200 million, along with about 500 million oyster larvae and spat on shell for restoration work.

Small farms, cleaner water

Most of New York's shellfish aquaculture is made up of small, family-owned operations, and the governor's office framed the investment as support for that industry and for the state's Blue Food Transformation initiative, launched in 2024 to build up New York's seafood economy. Earlier this year the state also helped secure a federal agricultural disaster designation for Long Island's shellfish industry.

The bay gets something out of it too. Oysters filter water as they feed and draw down excess nutrients, so every market oyster and every restoration reef seeded from the hatchery does a share of cleanup work in Great South Bay while it grows.

Supervisor Carpenter, who hosted the governor's tour, said the hatchery supports the local oyster growers, the local economy and the health of Great South Bay itself.

What happens next

The additional funding advances construction of the new facility on Great South Bay. The state has not announced an opening date. When the doors do open, the projection on the table is as much as five times the current seed stock, grown a short boat ride from the plots where it will be planted.
