Depends on your time frame. I stocked 100 BG 2" long +- into a 1 acre pond in early spring. they spawned same year & it is loaded with them. I did wait to stock LMB. On CC with my experience on another pond I have do not stock anymore then you want to harvest. They will eat everything when they get big. I do have a pond with two huge CC that I enjoy watching eat.
I am in southern Oklahoma so my growing season on BG is longer.
