From firsthand experience, I don't think funding is a major issue for this project. The task of making a "safe" list is daunting, and I believe impossible to do just because of how taxonomy is not a static science. Most likely, the job will be contracted out to a number of universities for grad students to work on for slave wages. This keeps the real work out of USFWS hands, and in the hands of academia. There's enough money floating around USFWS to regionally dole some out for graduate-level projects across the country. If this were my project, the most logical way to approach it would be to primarily focus on fishes with high invasive potentials. They immediately (with documented reasons) would be on the "no" list based on the region in question. Then the "safe" list would be made by analyzing fishes that wholesalers are moving into pet stores. Many fishes would be immediately placed on a "safe list" because they pose no invasive threat. Questionable fish could easily be analyzed in controlled experiments in labs, or better yet, experimental ponds and raceways. It would be a task, but I don't think it's an impossible undertaking. Hopefully science will remain true, and the invasive potential of fish will really be considered instead of a knee-jerk reaction to ban just because the fish might be able to live in a certain area. Just because a fish might be able to live in a certain area does not mean it will necessarily make a noticable impact on the ecosystem.
For instance, I've mentioned the scurge of suckermouth catfish on spring-fed systems in Texas. Detrimental? Definitely. Should they have been banned
in this state a long time ago? Certain species of suckermouths, yes. On the other hand, back in the 1890's rock bass were introduced in the San Marcos River. Sure, they probably eat some endangered salamanders and fountain darters, but they are not considered invasive because they are pretty much kept in check by eeking out a living in a niche filled by the warmouth and other centrarchids.
I don't think fish will be banned across the US just because of invasive potential in Florida. Maybe Florida will be forced, due to regional regulations (which they needed to get a hold of a long time ago), to change how they run their farms.
People have brought up blanket bans on flora and fauna in Australia and parts of Western Europe. If commmon sense prevails (maybe, there's a chance), it will be made apparent that, for the most part, this idea is ludicrous in the US. Regionally, many problems could have been avoided west of the rockies and in Florida if people had understood invasions and natural resource protection for the past 100+ years. This didn't happen and now we're in a mess. Most of the invasives in this country are from this country, anyway.
Maybe the pet industry will be forced to take some responsibility in the push to protect ecosystems. A system that is healthy (as in not dammed up, stripped down, polluted, etc.) is generally more resilient and resistant to invasions. When systems become degraded, the natives that have evolved to live in them don't do as well, and niches are freed up/created just waiting to be filled. If the pet industry wants to move an animal that is questionable on it's invasion potential into an area for the pet trade, they will have a much better chance on getting a green light on that species if they can justify why the animal/plant they want to sell has a low invasion potential. The statement "animal x could not withstand the seasonal drying/flash flooding" would definitely help get an animal a green light if it was in question for an area.
As has been said before, it all falls back on the responsibilty of the pet industry to educate its patrons. It has failed miserably in this respect. Also states, for the most part, have failed miserably by allowing wholesale stocking of native invaders into altered/degraded systems. As for fish farms, we know hurricanes hit. We also know that ponds flood and get mixed around when this happens. Fish get released into the surrounding environment, and in South Florida, become established. Knowing all of this, what has been done to prevent it? Walls or dyes might be a start. There are other solutions, too, I'm sure. Nobody seems to have jumped on these solutions, and we need to address the issue.
For the Betta folks, I don't think y'all have anything to worry about. I think the fear of people getting their fish taken away is about on par with the fear of getting your guns taken away. Have you tried to buy ammo lately? It's ridiculous.
I hate the idea of a nanny state, but this is beyond the issue of the gov't just telling us what to do to save us from ourselves. In it's purest sense, I think regulations on the pet/plant industry are to protect a resource that is all of ours from a minority that has a track record of putting it at risk, directly or indirectly, for personal profit. What has the pet industry done to negate its impact on the environment in South Florida, as well as other places prone to invasions? Not much that I can tell. If they had any sense, they would work something out very soon for the PR aspect if nothing alse.
