I'm not the best guy to ask regarding breeding/commercialization of native species here in TX, because currently I don't do that. That being said, here are some of Texas' byzantine regulations and attempts at interpretation by TPWD officials who sometimes don't really understand what the statutes say (e.g. their FAQs can at times be misleading interpretations of the no-kidding Texas Parks and Wildlife Code).
Texas recently (well, past 10 years or so) divided up many species of herps and other animals into a "white list" and a "black list," with regulations regarding what you can do with "white list" species being more permissive than those for the "black list."The somewhat confusing and contradictory "official" TPWD FAQ on white/black list speciesWhite List SpeciesBlack List Species
