I restock HBG about every year so they will not die out. One year we lost most of our HBG population and nothing came feeding. Right now there is a couple of HBG spawning in the pond I guess it could be one of them species. We have caught green sunfish but they are kept if caught.
Take someone new fishing at your pond. They'll be hooked forever. 1 acre LMB/HBG/BG pond
