The situation you have with otter, is one that is constantly brought up by locals in the form of resolutions, that are then presented to the gov't and their powers to be. Because, this has never been a wide spread "problem", it is not often that any wholesale changes are made. I, do believe, there has on different occasions, minor adjustments made to quotas. Secondly, are the adjoining trappers, having the same problem as you. Ask and find out ?? And thirdly -- There is also studies out that indicate, otter do not adversely affect beaver population and they state why they make such statements. Maybe, tularemia or food supply could be the problem. I'm lucky I don't have your problem cuz, I've only got a quota of 2..
If you want to get more activity, during the dog days of July, you'll have to find that "soft spot ",
