Bob,

Yes, I have a very good population of them...when I did an electro-survey this spring, they were popping out of the water like popcorn.

I have no idea how they got established (maybe the old bird discussion) but am very happy to have them. I can't really determine the effect they have on the food chain, but certainly believe they are very positive.

Never thought of trying to catch them for bait..do you cast net them like the saltwater version?
