I had similar problems on my pond but with a pair of great blue herons. These are beautiful stately birds and I should feel honored that they chose my pond to feed, but the sight of one of them nabbing one of my bass didn't sit well with me. My problem is, or was, lack of habitat or hiding places for my fish. My water was also pretty clear, 3 to 4 foot with a secchi disk, so they had a field day. I started to build habitat and now that most of the structures have been there for a year the fish have a place to hide. I know this is working because now I can regularly see the herons wading in the shallows which they never did before. Without cover they just flew in and BAM, caught a fish. Now they have to work for it and although they spend more time doing it, they don't seem to be as successfull. In my mind I've been doubly successfull, these are beautiful birds and they spend more time hunting around my shallows, and my fish have a fighting (or hiding) chance.
