Aquaculture Leasing
How Long Island's Shellfish Industry Gets Its Footing
Recreational permits cover the wading clammer — but commercial growers operate under a very different framework. Two municipal programs, plus a Cornell-led training pipeline, shape nearly every working oyster and clam farm on Long Island today.
Commercial Leases
Suffolk County Shellfish Aquaculture Lease Program (SCALP)
Suffolk County Department of Economic Development & Planning
The backbone of commercial oyster and clam farming on the East End. SCALP administers underwater lease parcels across a designated Shellfish Cultivation Zone of more than 22,000 acres in Peconic Bay and Gardiners Bay — the framework most modern North Fork farms operate under.
- •Lease parcels averaging ~10 acres
- •Standard 10-year lease terms
- •Oyster farming, clam cultivation & off-bottom cage culture
- •Active in Southold, Riverhead, Shelter Island & East Hampton waters

Town of Islip Shellfish Cultivation Facility
Town of Islip — Environmental Control
More marine economic-development engine than lease program — Islip's facility is a working hatchery and nursery producing oyster seed, clam seed, and seaweed products that supply commercial growers and fuel water-quality restoration across the Great South Bay.
- •Hatchery & nursery operations
- •Oyster seed, clam seed & seaweed production
- •Supports Great South Bay restoration
- •The most locally relevant program for South Shore residents

Cornell Cooperative Extension — Suffolk County Marine Program
Cornell Cooperative Extension of Suffolk County
Not a municipal lease program, but the connective tissue of Long Island aquaculture. CCE runs SPAT (Southold Project in Aquaculture Training), shellfish and bay scallop restoration, and hatchery operations — typically the first entry point for anyone trying to break into oyster farming on Long Island.
- •SPAT aquaculture training
- •Shellfish & bay scallop restoration
- •Hatchery operations & research
- •Pathway into the commercial industry
Visit the CCE Marine Program →The Real Bottleneck
Demand for Long Island oysters is exceptionally strong. The constraints on the industry are lease availability, permitting, waterfront access, and capital for gear and boats — not buyers. That dynamic leaves real room for adjacent businesses: hatchery supply, marine equipment, municipal restoration contracts, aquaculture tourism, and floating raw-bar concepts built around the farms themselves.
