The current Chief of Freshwater Fisheries feels mortality isn't affected by barbs or trebles and has studies to back that up. So impossible more or less. But if it did happen, it couldn't happen until 1/1/2016 which is the next regulatory change period for fisheries. We just started the most recent reg changes on the 1st of this year and they are on a two year cycle just like hunting (which is on a different cycle, 1/1/2013 - 12/31/2014).
