The Asian Shore Crab (Hemigrapsus sanguineus) originated in the western part of the Pacific Ocean, near Japan, China and Korea. It was first identified in the U.S. in 1988 at Cape May, New Jersey and now ranges from Maine to North Carolina. It is thought to have arrived in the United States as larvae in ballast discharged from cargo ships from these areas. It competes for similar habitat to native blue crab, rock crab, and lobster. The Asian Crab's breeding season is twice as long as native species so its wide-ranging appetite and growing population threaten both coastal ecosystems and aquaculture operations.
