Pond Boss Forums MANAGING AN EXISTING POND Corrective stocking Stocking a pond--recommendation from local fishery

I thought that, over time, GSF cross-breed with bluegill, and their genes are dominant, thus eventually ending back up with a population of GSF? --- No. BG and GSF will first try to spawn with their kind and they are both very protective. They will cross in some cases but not normal in a standard pond situation. Once they cross they are HBG and can not go back to either BG or GSF. HBG offspring are not wanted due to outbreeding depression. BG will out reproduce GSF all other things being equal.

Why do you have to reduce the GSF population? --- To increase the BG fry and FH survival rate. Same for LMB stockers if small ones are used. Also to have less competition for the pellets so BG can eat and grow faster. I would take out bigger GSF by angling not necessarily trap the small ones.
