DD1, yes I've found it strange that GSF increase in abundance while BG dwindle.
If indeed GSF spawn earlier at lower water temp than BG, the greenie fry and fingerlings could be gobbling up the later hatched BG?
The BG stockers went in the year I started hammering down the LMB numbers. I took out just over 100 LMB that year. The next year, the year I stocked GSF, I only was able to remove approx 45 LMB. Year after that, 30 something. This year it's down in the teens, and a number of LMB are eating Optimal BG, so have little need to eat sunfish.
It could be the LMB got too many BG early on, although the year after I stocked BG I could catch and release a few each day I fished.
Pardon my late reply. I travelled to se Colorado for several days of excellent dove hunting.
Brad, thanks for you posts. We may soon have some answers.
