depends on the water body type I caught it in.
Riverine systems are robust and the fish have the ability to move to where the food is located. In a lake or pond there is a finite forage base that I could possibly see them impacting.
Watched a pretty good series of Robert Field videos on the topic. He toured the river with a Virginia state biologist who was under the opinion that the snake head is not out competing other fish and the population has stabilized. LMB love the snakehead fry!
Here is the 3rd video in the series with the biologist

Amazing how strong they are. They really have to crank up the electroshock to stun them.
I am not a scientist but I did stay at a Holiday Inn Express last night!
