Post Here: Definition Topic/Audiences/Exigence > Environmental Impact and Ecological Threat Posed by the Northern Snakehead

Topic: The recent introduction of the northern snakehead (Channa Argus) to the Potomac River has gained much media attention and even some controversy over the years. What threat does the northern snakehead specifically pose to the ecosystems of aquatic Maryland.

Lay Audience: Anyone interested in the ecological issues and questions or local impacts of conservation and invasive species. Anyone interested in environmental science or the impact humans have on the planet, as invasive species are a mechanism of humans transporting species to regions where they are not native.

Technical Audience: Policymakers, ecological scientists, environmental biologists, anyone who works on conservation projects in the Potomac River and Chesapeake Bay, even some professional fishermen.

Exigence: The discovery of snakehead in the Potomac River and Chesapeake Bay watershed area spawned a wave of terrifying and dramatic articles emphasizing the snakehead’s mouth full of sharp, predatory teeth; ability to travel short, muddy distances over land; and potential to throw off the delicate balance of Maryland’s aquatic ecosystems. The Potomac River and Chesapeake Bay are well-documented to be watershed areas are among the most diverse aquatic ecosystems on the East Coast of the United States. Among the native and naturalized species native to the aquatic ecosystems are the bald eagle, the oyster, and the blue crab. Native species in the Chesapeake Bay watershed region, whether aquatic or not, are dependent on the health and stability of the local waters. In order to understand whether or not the snakehead poses a threat to Maryland’s aquatic ecosystems, we look to researchers and policymakers working together to ascertain the threat level posed by invasive species such as the snakehead.
