Leo, the majority of BG in my pond were sourced from a local lake, and haven't seen a pellet before being stocked into my pond. The lake was last stocked by the DNR in 1969. I stocked a couple hundred YOY BG from Cecil 2 years ago, but with the predators in the pond I doubt enough survived to make a difference. They were stocked right before the winter, so there was little cover for them to hide in for a number of months and their growth in that time would have been minimal.
