Anybody have any tried and true methods for catching river otter along open streams or rivers? I need something that is effective, but prevents birds from getting in it. I've tried submerged 220's around their "toilet" areas and have had them dance all around them, but with ice overhang its hard to make a set a good set for more than a few hours since the ice is constantly moving. I did catch one in a cubby with a #2 foot hold, but I'm afraid of birds eating the otter before I get to it... Ive heard of using buckets and 220's similar to wolverine sets. The problem is I don't want the birds to eat my catch before I get to them, so something underwater would be better. Any info would be appreciated.
