I am by far an expert on any of this. But heres my idea. Fence off a small section of your pond with netting (Seine net). It would only take a few t-post and the netting. Might be pretty cold setting it up this time of year thou. You would have to worry bout any kind of system setup this way. I'm sure someone with more knowledge will chime in but this is what i would do. And plan on doing this spring.
