I've debated with PETA activists, and they sure do make easy targets when something like this comes along. But I still don't think the US Bill is a PETA driven one.There is a sound ecological argument behind it. It's using a cannon to wound a mouse, and is hopefully going to get dumped. But our hobby has failed dismally in regulating itself, and that makes us as easy a target as PETA is.
Yes, the introductions of invasives issue can be government driven, with Gambusia as the poster child and Tilapia right behind. In the south of the US though, it's Oscars, plecos, Midas Cichlids, etc. It's people who want arapaimas, northern snakeheads, etc. They're the "kick me" sign on the back of the aquarium hobby.
