that's nothing new! They've already overtaken the southern rivers. Stupid things jump out of the water when scared and routinely injure people in boats. Second vid they are shooting them out of the air with bowfishing rigs. I've also seen people shoot them with shotguns like you would a clay pigeon. There's lots of speculation on the kind of harm they have done and will do to the native species. Time will tell, but they sure aren't helping any.
