This is a difficult topic.The intended goalof 713 is humane treatment of wildlife. That includes hunting, but in a humane manner. I am not an anti-hunting advocate and neither is my wife ( whom also worked on the bear and cougar init). We both understand that management is something that has to be done for the benefit of a species. She and others are concerned about how humanely these animals are being killed. Your statement that these people are chipping away at the rights of hunters, and that these people do not want any animal killed is not completely accurate. While some have that idea that is the minority.
Traps and poisons are indiscriminent. You have to admit that these devices prolong the agony of whatever animal is caught in them (wether or not you think that is ok). We dont allow people to fish with dynamite, and we argue that nets are indiscriminate to native fish species as well as birds and mammals, well so are traps.
I will leave this post and get back to its intent, fishing.
