If you stock 50 LMB you are slightly under stocking your preditors which can end up being very advantageous especially if you like catching large bass! Those origionally stocked 50 should have outstanding growth rates and do a decent job of keeping the bluegill in check. Bc you undwrstocked the LMB the bluegill should maintain high numbers and be easy to catch. If you want grow trophy bluegill you should probably stock more LMB or consider another type of predator species. If you go that route it will be somewhat harder to catch bluegill in the pond but they will tend to be bigger nicer fish.

That’s the best part it’s your world and you get to create whatever environment you want!! The only thing you probably should def do is stock small LMB. If you stock fish that are in the 5-7 inch range or larger they could easily get big enough by end of season to start taking out your brood stock bluegill which you def don’t want!
