Lb, save all your halibut, rockfish and white fleshed fish skins, heads, bones and rot them in a bucket for at least a year. Seal the bucket to keep the flies out. After a year, slowly open the lid, and I mean slowly, then strain the juice through a window screen , add glycol according to your climate down there and funnel it into a clean dish soap bottle. Put it in a gallon ziplock and when your ready just open the bag, pry the snap spout open on a tree, squirt on the pole and close it on a tree, hang a wing and you're good to go. I've got hundreds of marten with this over the years. Tried salmon once and didn't have much luck. Everything seems to like it including wolves. To change it up you can add a little skunk to it, but then the wolves wont have nothing to do with it. Be careful this can be ugly.
