Good, manual trapping helps reduce populations - well done. What are your fishery species again? General population dynamics of apex predators? Have you experienced general reduction in macrophytes/FA due to dense crayfish populations? My .25 ac pond had all vegetation and algae denuded due to crays - my BG and RES couldn't keep up with YOY and had far too many adults. Even a few SMB couldn't help the situation, had to drain, seine, and start over [4 times!].

Many men go fishing all of their lives without knowing that it is not fish they are after. ~ Henry David Thoreau
