The Town of Islip is dedicated to the responsible development of the aquaculture industry, while expanding our marine-based economy, enhancing our shellfish production and improving the water quality of the Great South Bay.
The Town of Islip Shellfish Cultivation Facility produces the highest quality shellfish and seaweed products for growers and distributors throughout the country. Our hatchery plays a vital role in meeting the needs of the aquaculture community and ensures the continuation of the tradition of farming on the Great South Bay.
In the 1980’s the Great South Bay began to see a steady and significant decline in shellfish production due in part to over harvesting and algae blooms such as brown tide.
In 1985 the Town of Islip established a Division of Bay Management and Shellfish Management that included the development of a shellfish culture facility to help augment the spawning of oysters and clams.
In 2009, the Town established the Bay Bottom Aquaculture Licensing Program, which encompasses over 1,500 acres of Town-owned bay bottom. The intent of the program is to have individuals with experience in shellfish cultivation that are committed to promote the overall health of the Great South Bay’s ecosystem thru sustainable farming
The Town of Islip’s Shellfish Cultivation Facility and the Bay Bottom Program focuses on restoring the value of the Great South Bay’s historical success.
Bay Bottom Aquaculture Licensing Program
The Program is a partnership of government, local business and individuals working together to manage parcels of underwater land in the Great South Bay to grow oysters, hard clams, bay scallops and kelp.
The Town currently has a waiting list for future available parcels. To place your name on the waiting list, contact the Department of Environmental Control (DEC), by clicking HERE, or by calling the DEC at (631) 595-3630.
Phase III Expansion
The environmental benefits of the expansion of Phase III are multi-faceted. The most apparent benefit to the sizable Phase III expansion will be a significant volume of bay water filtered as a result of the addition of millions of shellfish to the cultivation site. Biofiltration by shellfish is an acknowledged method of algae population control, which improves water quality. Having cages and trays on the bay bottom also provides protection and a habitat for small fish, crabs and other marine life, which increases the biodiversity of the bay.
Another environmental benefit of having millions of clams and oysters growing in the same location is they will spawn and provide larvae to set up in the bay. The Town has received feedback from Growers in Phase I and Phase II that they are finding natural set oysters and scallops in the areas around the cultivation site. Shellfish from this program are naturally spawning, reproducing and are showing up on our shorelines. This will have a direct positive effect on our natural resource by enhancing the wild fishery. The filtering capacity from culturing these shellfish in Islip waters is enormous. The millions of shellfish grown at the Facility and placed at the Phase I and II cultivation site are naturally and efficiently filtering 330-550 million gallons a day of the Great South Bay’s water. The filtering reduces the turbidity, improves light penetration, reduces anoxia and improves the overall water quality.
If you are interested in placing your name on the waiting list or submitting comment on the expansion proposal please call the DEC at (631) 595-3630.
