Hey ewest thanks for help ,I understand some peoples thoughts on the Herons and I think the trout now are too big for the Herons .I will let them feast on the frogs and minnows . I put a horse trough full of shiners in my pond each spring for food for the trout. Get them locally at this time of the year out of the ditchs leading from a lake close by .
The worst problem we have here is the Commorants and I have seen first hand how much damage they can do to a trout pond . Once they know there are fish in the pond they will not leave to they have eaten every one, and of course these suckers are also a protected species. I tried a floating gator last year to no effect didn't scare them a bit . But they do seem a little shy when I go visit my pond with my trusty sidekick Browning. Take care all. Thanks for all the advice and help. This is great place for info.
