Since 1991, The Wetlands Institute has brought scientists and volunteers together to conduct surveys of horseshoe crabs spawning on New Jersey’s Delaware Bay beaches. These surveys take place during full and new moon phases during the months of May and June at the height of the spawning season. During this time, thousands of crabs crawl onto Delaware Bay beaches to lay their eggs in nests along the shoreline’s high tide line. Our horseshoe crab spawning surveys are coordinated with other groups in New Jersey and Delaware so that they are standardized and take place on the same dates and tides. By taking snap shot counts of the number of horseshoe crabs spawning on Delaware Bay beaches, scientists are able to gain insight to the Delaware Bay’s horseshoe crab population status and trends.
