you're LMB and HSB will annihilate those bh yoy this fall. I bet they were still balled up when they entered the trap - that's awesome!
Are you going to keep the GSF in the pond? Have you thought about feed training them?
Interestingly, I could hold ~6 BH in my palm and immediately those needle sharp spines would start burning into me as they flopped about. Perhaps a 4" bass would rather eat FHM. Hope I can catch more balled up schools if there are any.
I prefer old school native BG so I won't be promoting GSF. As of now I don't plan to feed fish, nor aerate.
