The purpose of this rule amendment is to allow a person diving in state waters by means of a rebreather to harvest and possess lionfish. Harvest by divers is currently the primary means of lionfish population control, but harvest of any marine species while diving by means of a rebreather is currently prohibited. The effect of this rule amendment will be to generate additional opportunities for divers to remove invasive lionfish from Florida’s waters, by removing a regulatory impediment to their harvest.
