Eric, it's the SMB reproduction pond we're talking about. I added 4 BG to provide forage for 4 months over Summer as an experiment. Since I can't get out and feed daily, and auto feeders dump way too much into the pond at a given time leading to nutrient overload, adding some natural forage helped my SMB recruitment and overall body condition tremendously this year. The BG apparently spawned a couple times over the Summer, and the YOY SMB responded very well. I'll definitely be doing it again this Summer - helped solve the nourishment issue I've been facing with they YOY SMB the past several seasons. I will probably add some FHM early season to allow them to reproduce a few times before I stock the brood fish, maybe some GSH - not sure. Goal here is to feed the SMB offspring for maximum growth.
