Jersey, I think I remember seeing that somewhere, but many ponds have them, some exclusively. Maybe some have experienced this. Blues would be more apt to I wound think. If you have good solid banks and no errosion, I wouldnt worry about it. As I said, there are thousands of ponds with them, and I have only seen it mentioned once. Hopefully we will get more on this. If you like fishing for kids or grandkids, as I do, I would definitely want some. Just go light on the stocking considering the size of your pond, or some will not be caught and grow too big.
