Sponsor 1,000 Oysters
CSLI will raise 1,000 oysters in your name!
We will send photos of our volunteers cleaning, measuring, and caring for the oysters every 2 weeks. In the fall or early winter, you’ll receive a video of them being released into Mt. Sinai or Port Jefferson Harbor where they will join our thousands of other oysters placed there to grow into mature oysters, repopulating the harbors and cleaning the water.
