Title Addendum VII to the Interstate Fishery Management Plan for Horseshoe Crabs for Public Comment.

Abstract The horseshoe crab is a benthic or bottom-dwelling arthropod that utilizes both estuarine and continental shelf habitats. The horseshoe crab is an ecological generalist and although it is called a 'crab,' it is not a true crab, but rather is more closely related to the arachnids. Horseshoe crabs range from the Yucatan peninsula to northern Maine. Horseshoe crabs were traditionally used for fertilizer and livestock food in the late 1800s and early 1900s. During this period of time, harvest was substantial (over 4 million crabs were landed annually in Delaware Bay). However, evidence suggests that stocks were depleted by the 1940s and commercial harvesting of horseshoe crabs ceased in the 1960s. By the late 1970s, observations of spawning horseshoe crabs indicated that the population had substantially recovered. Recently, renewed commercial interest in horseshoe crabs has been driven by their use as bait in the American eel and conch pot fisheries, and use of horseshoe crab blood by the biomedical industry. Between 1990 and 1996, reported harvest in several states (e.g., New Jersey, Delaware, and Maryland) has increased. During this period of time, several cases of apparent localized population declines may have occurred within the Delaware Bay. The goal of this plan is to conserve and protect the horseshoe crab resource to maintain sustainable levels of spawning stock biomass to ensure its continued role in the ecology of coastal ecosystems, while providing for continued use over time.
