While I suppose that at least for now these piebalds will remain shrouded in mystery, after conversing with a non-biased authority on the subject of the bans in place in Mexico, it appears that permits can indeed be obtained for importation of fish into the USA as long as the exporter is a registered company, and the species of fish at the time of export is not on a protection list.
I don't expect anyone to produce any import statements or permits, or name their exporter/s, that's obviously not going to happen, but at least we can remove any doubt that wild fish can under the proper conditions be exported out of the country in question. Different permits, different variables involved, but it sounds like it's doable. I suspect that if anyone knew how to go about getting permits in that part of the world it would be Don Conkel.
