Conservation group asks New Jersey to take action over biomedical bleeding of horseshoe crabs

The decline that preceded the recovery alarmed wildlife managers because horseshoe crabs play a critical role in both the coastal ecosystem and modern medicine. According to Cape Cod National Seashore, the animals are harvested for bait in eel and whelk fisheries, while their blue blood is used to produce Limulus amebocyte lysate, a substance used to detect bacterial contamination in injectable drugs, vaccines and implantable medical devices.
