I'm involved in management of several nice ponds right now, so I'll give them example of Bill Westlund's pond near Lincoln, NE

Year stocked: 1999 (I think...I'll check)
Size of Lake: 2.5 acres
Number of CC stocked: 100
Approximate number of CC removed to eat: 80 so far
Approximate size of CC removed: 24 inches
Restocking plans: Not currently. Landowner likes LMB, BG and BC, and feels that the CC were taking almost all of the feed and although he enjoys them, he wants them to play a smaller roll for now.
Will he let them die out?: He may consider restocking 20 or so in the next two to three years.

Holding a redear sunfish is like running with scissors.
