Right - well - goldfish are running rampant in northern lakes as are koi - are they going to be banned? IDK? Lionfish - we all know the story. Cichlids in Florida canals? Will Cichlids be banned - Discus? IDK. The point - you're taking a sanguine approach - that the government is going to do the right thing - based on science. I would suggest that the Hawaiian ban alone suggests we may very well be in trouble in this hobby.
The federal government already has the power to ban injurious species from importation. They also have the ability to investigate and enforce state bans on any injurious species. In theory the government already has all the power it needs to classify goldfish and koi as invasive species(as far as I am aware they havent) The big change in this bill is once it is listed as injurious then the federal government can prohibit interstate trade even if the state does not specifically ban that species. Because of this I am not sure I get your point. If the US wants to ban koi from importation today they have that legal ability..... yet they havent?
