What Is a Snakehead Fish
Snakehead fish are freshwater predatory fish in the family Channidae. They have elongated bodies, large mouths, and can breathe air using a primitive lung-like organ.
Why Snakehead Fish Are Invasive
Snakehead fish are invasive because they reproduce quickly, tolerate a wide range of conditions, and have no natural predators in non-native waters. They outcompete native species for food and habitat, reducing biodiversity in lakes, rivers, and wetlands.
Spread, Impact, and Management
Snakehead fish spread through illegal releases, accidental escapes from aquaculture, and the live food trade. Their expansion can affect local fisheries, recreational fishing, and ecosystem balance. Agencies monitor populations and encourage immediate reporting and removal.
