On Lake of the Ozarks, we have a rogue otter that is stealing fish out of our baskets before we get them cleaned. Tried a snare on top of the wire baskets, but he just pushes them aside and helps himself. DNR said, "Go ahead and shoot it" Not going to do that for fear of float/dock damage, etc. Question: use conibear or leg hold trap? If so, what size? Thanks for any help offered.
