IMO this pond is not worth the trouble or cost to set up aeration. It is pretty much unattended from October through April. Is there a species that can survive better in low temps and low DO
If you were in NY on Lake Ontario - Bullhead would make it if they aren't already there. I doubt your situation is much different then some that I'm familiar with.
The "ponds" like you describe that do "OK" on lake ontario - have :
1. an inlet & a "cut"
2. or at least a "cut" in the dune - to the main lake.
Obviously in either situation your local fish run the risk of escaping - but at the same time you get a pretty neat natural fishery with the "cut". its also their way in and out in the event of low oxygen.
On of my favorite spots (Sterling Creek Pond at Fair Haven NY) has Crappie, Northern Pike, Bowfin, LMB and even EEL during the summer months - and Rainbow trout, Brown trout and King Salmon in the fall.
F-H
