I’m sure most if not all are still hybrids.
I put 250 HBG in myself back in sept of 2016. Also bought from NEMO hatchery, they’ve been nothing but trouble since introduced. We swam every day last weekend, and they nip the floating adults.
I’m not willing to drain and start over, and I won’t add LMB or CC. It’s just going to always be a battle. I usually comment/warn anyone looking at a SMB YP pond, to “NOT” consider adding HBG or BG.
I’m not that far from Boone County, let me know if you need help with a seine. I’m retired, so my schedule is fairly flexible. Good luck.

Maybe you could refresh your RES genetics with an infusion of good stock from a reliable supplier?
