Well my first hatch of bluegills of July 08 where I crossed some of Bruce Condello's bluegills with some of my existing stock were separated from some yellow perch in a cage and put into their own cage for the winter today. I need to sort the perch by sex in the cages next spring and don't want to handle the bluegills in that cold of water if I don't have to. I will sort the yellow perch and dump the female yellow perch into the pond cage free in March.
Anyway average size for these 1 year 3 month old fish is about 6 inches with the largest at 6 7/8 inches and 6 1/4 oz. (Don't have a gram scale.)These fish have been in the cage most of their lives.
Here are a few pics.

Once again a special thanks to Bruce Condello for the fine stock I got from him.
Note: I do not supply any fish for stocking. My fish are produced for my own use. Bruce is the man to contact if you want any of his excellent stock.
