I have to side with the biologists on this one, listed INVASIVE for a reason, and no it's not a government conspiracy. We INTRODUCE fish into our water ways with careful consideration. As explained to me an INVASIVE fish will DISPLACE the other fish by eating all the food and spawning twice as fast. Yes you caught a bass where snakeheads are but were there more bass there before, have the other fish moved on because of lack of food ? I'm not a fan of these fish nor Flathead catfish, BUT both are good eating.
Some parts of the world brown trout are listed as invasive, maybe the brown trout we introduced became invasive to brook trout, so we never really know. In Round Valley after the lake trout took over the brown trout went nuts looking for food, it was no big deal in the end before the baitfish crashed to cast a live herring out and catch a big brown trout instantly, the browns were starving. The introduction of lake trout was not thought out very well and an INTRODUCED fish became INVASIVE in a way.
It's just humans HOMOGANIZING the earth, by picking things up and putting them down where they don't belong, and it's only going to get worse. Despite all this nature has a way of taking care of things, there is no EXCESS in nature.
I'm torn by this and wish there were more answers.
