You will have to feed the CNBG in the hatchery pond, and since not all fish grow at the same rate AND you will have multiple spawns, you will be stocking a multitude of sizes, not just >3" BG. The only way to do that is to seine and grade the fish, returning the smaller ones to the hatchery pond to grow larger.
