Invasive fish competition returns with anglers making 'Reel Rewards'

"Invasive fish species threaten the Baltimore Harbor ecosystem, economy, and native species," the group's website says. 

"Invasive snakehead, blue catfish, and flathead catfish prey on and compete for resources with native species that are important to anglers and businesses," the site also notes.

Snakeheads have scales similar to a boa or python, giving meaning to their name.

They can be found at the bottom of shallow, slow-moving, weedy waters, according to the U.S. Fish and Wildlife Service (FWS).

The fish have large mouths full of pointed teeth, according to FWS.

Snakeheads vary in size, but generally range from stretching a few inches to over three feet long, according to New York Invasive Species.
