Good addition to the thread, 4Corners!

Culling 300 LMB over a three year span in a 1/4 acre pond shows just how productive a small pond can be. That is a lot of fish mass in a small space, I wonder if you were getting close to a fish kill?

Did you ever have a good population of YP in your pond?

I like the idea of a small pond that is YP only. Buy pellet-trained (if you can) and start them with good forage minnows and an automatic feeder. When the YP are large enough to eat, start catching them and ladder stock some more YP if you did not have good recruitment.
