What Are Invasive Species in the Chesapeake Bay
Invasive species are nonnative plants, animals, and pathogens that spread quickly and disrupt the Chesapeake Bay ecosystem. They often arrive through ballast water, aquaculture, and accidental releases.
Key Invasive Species in the Chesapeake Bay
Notable invaders include the blue catfish, northern snakehead, and Asian shore crab. The Chesapeake Bay Program tracks these species and their impacts on native fisheries and habitats.
Why Invasive Species Matter for the Bay
Invasive species compete with native fish and shellfish for food and habitat. They can alter water quality, reduce biodiversity, and affect local economies that depend on fishing and tourism.
Management efforts include monitoring, targeted removals, and public outreach. Learn more about current programs at https://www.chesapeakebay.net/invasive-species.
