    Are you a crabber, waterman, or concerned citizen? We need your help to detect and assess the status of Chinese Mitten Crabs. The "Mitten Crab Watch" website provides information on the invasion of the mitten crab and allows users to more easily report catches.

    Please help us detect live mitten crabs by reporting any sighting in North America. We are especially interested in collecting sightings from the Chesapeake Bay, Delaware Bay, Hudson River, and San Francisco Bay --- where the crab has been common in the past. Please visit the Mitten Crab Watch website to learn more about the crab and to report sightings.

Federally Regulated

  • DOI. FWS. Fish and Aquatic Conservation.

    Includes species listed as injurious wildlife under the Federal Lacey Act (18 USC 42), which makes it illegal to import injurious wildlife into the United States or transport between the listed jurisdictions in the shipment clause (the continental United States, the District of Columbia, Hawaii, the Commonwealth of Puerto Rico, and any possession of the United States) without a permit. An injurious wildlife listing would not prohibit intrastate transport or possession of that species within a State where those activities are not prohibited by the State.

    Injurious wildlife are wild mammals, wild birds, amphibians, reptiles, fishes, crustaceans, mollusks and their offspring or eggs that are injurious to the interests of human beings, agriculture, horticulture, forestry, wildlife or wildlife resources of the U.S. Plants and organisms other than those stated above cannot be listed as injurious wildlife.
