I purposely introduced some CNBG from Harbin Fish Farms in Central KS in hopes of limiting BG reproduction some-as Cody suggests "may" happen. I can't confirm that but with RES present, it's made for some interesting colors and some fast growing sunfish.
It seems the opercular tab is the best indicator of purest vs mixed/hybrid, or at least that is what I'm finding in common with other more visible ques.
Snipe,
Any reproduction of pure CNBG in your ponds?
Are the original stockers showing decent growth?
(I thought you were too far north for waters favorable to CNBG. I also thought that Harbin's CNBG came out of their Oklahoma operations. Of course there is a LOT that I don't know!)
