Thousands of invasive fish have been removed from the Chesapeake Bay watershed at the Conowingo Dam earlier this year and donated to local food banks through a continuing partnership between Maryland Department of Natural Resources and others. During the 2024 season, which ran from March to June, more than 18,000 pounds of invasive fish (blue catfish, flathead catfish, and northern snakehead) were removed from Maryland waters.
Maryland’s eastern shore has seen thousands of acres of protective marshland impacted by the nutria's destructive feeding habits. To protect the valuable resources of Maryland’s Chesapeake Bay, The Chesapeake Bay Nutria Eradication Project (CBNEP) began in 2002 to permanently remove invasive nutria from the marshes of the Delmarva Peninsula and to protect, enhance, and restore the aquatic and river ecosystems they damaged.

From March to May 2024, scientists from the USGS will install baiting platforms for invasive grass carp and equipment for monitoring fish movement in pool 19 of the Upper Mississippi River. Pool 19 contains 30,466 acres of aquatic habitat, extending 46.3 miles from Lock & Dam 19 located near Keokuk, Iowa upstream to Lock & Dam 18 located near Burlington, Iowa.
Project completion is expected by December 2024, with results being publicly available in 2025. This project is supported through the U.S. Geological Survey Ecosystems Mission Area, Biological Threats Research Program, and the Great Lakes Restoration Initiative.
