The pic is of a HBG. I assume you are going to stock 1500 BG. Is that correct ? HBG are different and will not provide much forage for the LMB.
Yes, it is BG being stocked. The BG/HBG/GSF in the pond now came from various ponds/lakes last year after the fish-kill. Before I knew any better. Does it appear the HBG in the photo may be pre-spawn? It seemed to have a pretty big belly.
