I have a pond that freezes over most winters for a month or two with up to 5 or 6 inches of ice. I do not aerate. During the winter it is 15 to 20 feet at its deepest below the ice. It is about an acre in size. gravel bottom. And mostly ground water filled..although in winter and spring a small spring feedsin and so overflows into a wetland swamp.

Would I expect the temp under the ice in this type of pond to be ok to sustain HSB? I currently have BG and LMB in the pond? Also what size and how many would be good to stock with an established LMB and BG population? The goal is recreational fishing.

Any advice would be helpful.

Thanks.
