The GSH and FHM that I stocked in my pond have had a 3yr jump on any predators. Shrimp, bluntnose minnows, and spotfin shiners had a one year jump. The schools of GSH will literally stretch nonstop across the dam which is 200'.
I just stocked the predators this spring. 50lb adult YP, 100 4-6" YP, 800 4-6" BG, 200 4" RES, 50 7-9" HSB, 50 4" LMB, and 150 12"+ RBT. We keep all trout that are caught for food...should be depleted by early June.
The RBT, YP, HSB, and BG are hitting pellets hard...but also will see them busting top of water hitting shiners. Shiners still get right in the middle of them hitting pellets though.
The GSH population exploded in pond W/O predators. I do not regret stocking them...should see tremendous growth out of other fish that just went into pond
