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.
It is crucial to keep the mussels from moving from Lake Powell to other lakes and rivers. Utah and Arizona state laws require you to clean, drain, and dry your boat when leaving Lake Powell using self-decontamination procedures. Additional steps are required if you launch on other waters without a significant drying period or if you are on Lake Powell for more than 5 days.
The National Animal Disease Preparedness and Response Program (NADPRP) strengthens our country's ability to combat animal disease outbreaks. Through this program, APHIS provides tens of millions in funding to States, producer organizations, universities, and others to carry out high-value projects that help our Nation prepare for the most critical animal health threats facing U.S. livestock industries today.
Building a structure for interagency coordination to support early detection surveillance and rapid response to invasive species. Scientists and resource managers agree that preventing invasive species establishment is the most cost-effective approach to avoiding many of the long-term economic, environmental, and societal costs associated with invasive species.
The Bipartisan Infrastructure Law (BIL) was passed in 2021, a portion of which was directed to funding invasive species detection, prevention, eradication, including research.

NEMESIS is a resource for information on non-native (or exotic) species that occur in coastal marine waters of the United States. This relational database compiles detailed information on approximately 500 different non-native species of plants, fish, invertebrates, protists and algae that have invaded our coastal waters. The database identifies which species have been reported, their current population status (i.e., whether established or not), as well as when, where, and how they invaded; it also summarizes key information on the biology, ecology, and known impacts of each invader.
