Since 1990, surveys have been conducted of horseshoe crabs spawning in Delaware Bay. Data collected by volunteers during these surveys is key for scientists in monitoring changes in numbers of spawning crabs in the Bay. Each spring during the new and full moon evening high tides in May and June, volunteers donate their time to count crabs on key beaches in Delaware and in New Jersey. Delaware’s well-trained and enthusiastic volunteers have made this program one of the most successful volunteer-based wildlife surveys in the country. For general information about the Horseshoe Crab spawning surveys assist with one of the other beaches, please visit the main Delaware Bay Horseshoe Crab Spawning Survey ( What role does DNERR play? The Delaware National Estuarine Research Reserve (DNERR) coordinates the survey on three Delaware Bay beaches each spring (Kitts Hummock, Ted Harvey Wildlife Area, North Bowers Beach). This is a wonderful way to see this natural spectacle on the Delaware Bay and we invite anyone who is interested in this fascinating creature to participate! *Volunteers are required to be trained in survey protocols before being able to participate in a survey.*
