OR, be a real sportsman, and put it back, they clean the bottoms of dying/dead vegetation, eat invasive plants, and other stuff that would otherwise rot and not be eaten by anything else.
Give me a good reason why they should be killed, being non-native isn't a good reason (Bass, Bluegill, and anything else not a salmonid are non-native), and the fact that they stir up a little mud (its a river for crying out loud, mud is everywhere) isn't a reason. Yes, they might enjoy a few eggs once in a while, WHAT FISH WOULDN'T? Catfish are nuts over eggs, do you kill them? Suckerfish love eggs, and they also do a fine job of eating algae off the river bottom.
Rascal,
Enlighten me with your knowledge (I mean Ignorance)
Waco,
the vibe I get tells me you wouldn't do such a thing.
P.S. LOL at your post Hitman, so true, if one doesn't agree or understand, then OPINION comes into play.
