We accept donations of any amount. When we receive your donation, we will send you a written thank you acknowledging your fully tax deductible donation.

The Hatchery is a not-for-profit environmental education center. More than 50,000 visitors including school, scout and many other types of groups learn about Long Island’s various freshwater environments. Since our education programs depend entirely on the support of memberships, admissions, and some key grant supported projects, we must add to our list of members, in order to keep these programs functioning.

Please join us! Membership offers one year of free admission, quarterly newsletters, invitations to special events, discounts on seasonal programs for children, and discounts in our gift shop.

The Cold Spring Harbor Fish Hatchery & Aquarium offers volunteer opportunities for adults and high school students.  Volunteers are needed to help out with the care of our animals, and or to assist at the Hatchery’s special events and educational programs.  No experience is necessary, training will be provided by members of the Hatchery’s staff.

Sponsor an Animal

The Cold Spring Harbor Fish Hatchery & Aquarium is home to the largest living collection of New York State freshwater fishes, reptiles and amphibians. Sponsoring an animal is great for gifts, children, adults, families, scout groups and schools. The money donated to the “Sponsor an Animal” program goes toward enhancing the livelihood of our animals by aiding in purchasing food, maintaining the exhibit habitat, assisting in veterinary care, and expanding our educational programming.

All sponsors will receive a 4x6 color photo and fact sheet about the animal, a certificate of sponsorship, and recognition on our sponsor's board.

Where are the fish stocked?
Fish are stocked all over Long Island and eastern New York and as far north as the Adirondacks.
What time of year are fish stocked?
We stock fish year round, but mostly in the spring and fall due to cooler temperatures. The warmer weather in July and August is more stressful for the trout and makes it more difficult to transport them.
What type of pond is ideal for trout?
Trout require cold, highly oxygenated water (50-65°F), but can tolerate temperatures up to 70°F for short periods of time.
What type of trout do you sell?
We currently sell rainbow and brook trout
Where do the eggs come from?
We take our own brook trout eggs from on-site broodstock.
What size fish do you stock?
The majority of the fish we stock range from 10"-18" brook and rainbow trout.
Where does the water come?
The water comes from spring water and six artesian wells. We get 50-75 gallons per minute of spring water from the Upper Spring Pond and 325 gallons per minutes of well water. This water is at a constant 52°F all year long. No pumps are used to move water through the Hatchery. The springs and artesian wells flow naturally from underground pressure and a slight pitch on the Hatchery grounds allows water to flow freely through the trout ponds.
What about New York State Disease Inspections?
The Hatchery has not tested positive for any certifiable diseases.
