I had a huge hatch of shiners this year and my RES pulled off a very good spawn too, YOY shiners are already 2", YOY RES 1-1/4". Most of my SMB are in the 8-10" size range so a 6" shiner is just competition for food with my SMB and RES. I did stock a total eight HSB two months ago. My big concern with having too many large GSH is the lack of recruitment of SMB that I have seen in the past, not sure why but RES seem to recruit well with large shiners present but SMB don't.
