The agreement restricts the collection of horseshoe crab on the beaches of over 30 islands across the South Carolina coast, and prohibits the temporary placement of female horseshoe crabs in holding ponds so they continue to spawn on the state’s beaches, among other measures.
The joint agreement was signed by South Carolina Department of Natural Resources, private companies Gault Seafood and Marsh Point Farm and the Southern Environmental Law Center, which is representing Defenders of Wildlife and the Coastal Conservation League.
The agreement provides for five years of enhanced protections for spawning horseshoe crabs and migrating red knots while ensuring continued access to horseshoe crabs for use in biomedical testing.
