Deb,
Those stocking rates seem insane to me. With 600 CC and 600 LMB it is no wonder the GG's grow so fast. They have NO competition from their offspring ( all would be eaten ). You could stock standard BG with a predator base that high and get just as good growth rates.
Do you tell your customers they need the pond dye? Is the dye to cover up the fact that 600 CC per acre turned their ponds into a turbulent mess?
Need your stocking rates/reasonings explained more in-depth. I was intrigued by the GG's until I started reading last post on stocking. I may be wrong, but it appears to me that you're just another hatchery feeding off the uninformed.
