I have a 1/2acre pond and there are over a hundred 1in to 4in bluegill's. Its around 6''ft deep in the middle,they have shelter. when it freezes over its around 6in thick if not more.It's over 5 years old and the only fish that lived in it were goldfish. Over the summer i put some bluegill in and now there are lots of them.I like bluegill and hope to fish for them from this pond. How many of these little guys will make it to see the warm sunny spring day's?
