Are There Snakeheads In Tennessee? Exploring The Invasive Species Threat

Is it illegal to have snakehead fish in Tennessee? Yes, snakeheads are classified as injurious to the environment species in Tennessee, and it is prohibited to possess them. This designation was made on January 12, 2006, to safeguard the local ecosystem from the potential harm these invasive fish can cause.

Snakehead fish, a group of invasive species, have been detected in various regions of the United States. One notable presence is that of the northern snakehead, which has successfully established populations in the Potomac River, spanning across Maryland, Virginia, and Washington D.C. Additionally, the blotched snakehead, scientifically known as Channa maculata, has been a longstanding inhabitant of Oahu, Hawaii, since the late 1800s. These introductions of snakeheads into different ecosystems in the United States have raised concerns about their environmental impact and the measures needed to manage and control their spread.

Which invasive fish species have established themselves in Tennessee, and how did they arrive in the state? Tennessee is home to several invasive carp species, namely silver carp, bighead carp, grass carp, and black carp. These non-native fish were introduced to the United States in the 1970s with the initial purpose of aiding in the maintenance of aquaculture ponds. Understanding both the species present and the historical context of their introduction sheds light on the invasive fish issue in Tennessee.
