Report your catch of invasive fish species (northern snakehead, blue catfish, flathead catfish) in the Chesapeake Watershed for a chance to win great prizes! The Great Chesapeake Invasives Count is an annual angling-based effort (April 1, 2024-March 31, 2025) to provide important data to the Maryland Department of Natural Resources, USFWS, and other management agencies on what you're seeing on the water. Information related to the number of fish you catch during a given time, as well as the length and weight of the fish you catch is important to fishery managers. It is also vital to investigate the feeding habits of invasive fish to help understand the short and long-term impacts that their existence may cause on native species. It is important that the public recognizes the impacts that these species can have on our natural ecosystems, and does not continue the spread of these fish.
