New administration at the wheel for two years now - is it still the fault of the notorious 1916 enviro-wackos?
Apply for an aquaculture license, then apply for a depredation permit to protect your aquaculture business. Cecil Baird did that [In IN] and was able to permanently discourage GBH that were hammering his trophy trout, IIRC. Or, try to source a time machine, maybe, and enlighten the 1916 wackos before they pass the legislation. If you decide the latter, be sure to bet against the Brooklyn Robins and cash in!
