Seems to me a legit fish farm, say in Hawai`i, could import fish from a legal source like a Singapore farm and start a breeding program. All fish could be chipped before sale, same as they are doing oversea, but domesticly. If our government wanted to use a percentage for conservation of the wild fish, no problem. It certainly would put no strain on wild populations, and might stop the black market, and you would think you could make a decent profit on such pricey fish. Plus, last I heard Tigers were endangered, but supposedly we have more in captivity around the world (and quite a few in the U.S.) than in the wild. That does not adress the conservation of habitat, but at least the animal is not extinct and now we have more Tigers than we have places to house them.
If overfishing or habitat destruction has cause this problem with the Asian Arowana, you can look for more of this in the future. There are several fish species that do not breed readily in captivity. Unless they have come up with artificial means of breeding, we may one day face the same situation with Clown Loaches, Knifefishes, Leporinus, or maybe some fish that you as a hobbiest enjoy. They will no longer be available.
To answer the poll question: I would buy one if it were legal in the U.S., I could get a permit for Florida and IF the price was right. But beauacracy being what it is, I don't look for that any time soon.
