What some bozo(does that term offend you too much?) chooses to stuff down the throat or up someplace else on a fish doesn't call for anything. Their current existence on the east coast of the US is what calls for their eradication. Their current existence in Mexico, where they are directly responsible for the vast majority of recent extinctions in the family Goodeidae calls for their eradication. A few examples: Skiffia francesae, Zoogeniticus tequila, Characodon garmani, Allotoca goslinei.Several of these fish still survive in aquaria. There are others, and many that have been brought to the brink of extinction because of Largemouth Bass introduction. You should educate yourself on the subject. My main point is that govt agencies need to stop supporting some invasives such as Bass, Rainbow Trout (not native east of the Mississippi), Brown Trout (native to Europe) while persecuting others. Since you seem to think that stocking non-native fish is ok I bet you can't wait for the Asian Carp you'll be seeing in the Lakes within a few years!
