Thanks for starting this discussion John and I hope I'm not hijacking here. I would love to get some thoughts from others. I'm not good at identification yet. I have been concerned that the "BG" I received at stocking were in fact mostly HBG (or even worse just GSF). I haven't kept a faithful log, but 90% of what I catch with a worm under a bobber are like the HBG/GSF in my pics attached. I was supposed to get 200 BG and 100 HBG at the time of stocking. I understand HBG should be more aggressive, but I hardly catch anything but what's in the pics.

My pond is only two years old and stocked last spring (2017). I think most seem to be doing well (most are 5-6" with an occasional 7-8"), but I'm not confident I got exactly what I was told.
