I'm suprised no "hybrid CC" are being sold. Seems like a Market exists.

I'm on year 3 of of a ladder stocking of CC, 25, 50, 50 in a .5 acre clay farm pond with very little to no structure. So far, no YOY that I have seen. It's not a fertile pond.
This fall I'm planning to harvest as many CC under 2lbs as I can.
