Virtual Birthday Party

Celebrate your birthday by inviting your friends to meet our reptiles and amphibians through Zoom. Interactive programming will give you and your guests a chance to learn about the amazing adaptations of these animals and ask our expert staff your very own questions. All parties last approximately 40-minutes long and cost $200. We recommend you keep groups small (maximum of approximately 15 children) to increase the time each child has to ask questions and interact with our staff.  Please contact krissyf@cshfishhatchery.org  with any questions or fill out and return our request form to schedule your party today!

Fish Sales

The Hatchery sells brook and rainbow trout for stocking purposes. If you are interested in purchasing trout, contact Steve DeSimone, Director, at (516) 692-6768. Trout pricing and delivery charges are subject to change. Please contact the Hatchery for the most up to date pricing. We’ll deliver a few dozen for backyard ponds or hundreds for sportsmen clubs. Place your orders early to ensure your preferred delivery date.

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.
