I have been wanting to travel down to the Potomac and fish for snakeheads for a while now. I really don't think that they are posing nearly as much of a threat as people thought that they would. They seem easy to target and basic bass techniques seem to work well in shallow weedy water that is also typical largemouth habitat.
One thing that I always find particularly humoring when buzz over invasive species starts happening is the old assumption that "they have no natural predators so nothing is going to eat them." This is one of the dumbest arguements I have ever heard and any fisherman should know that. I've caught bass and other fish on so many lures that resemble NOTHING NATURAL and they ate it. If a fish sees a smaller fish, or anything that resembles someting edible, and they have the easy opportunity to eat it, then they often times will. They don't discriminate and say, "oh, that's a snakehead, I can't eat that because I'm not supposed to be its predator." The only displaement issue would be if it takes over bass spawning areas and spawns earlier, grows faster, etc and then snakeheads are more likely to eat the YOY bass than vice versa. The snakeheads really don't seem to be affecting the largemouths too negatively, however. Let's not forget, Largemouths are also voracious predators with HUGE mouths that will eat A LOT.
