I’m located in west central Ohio and have had ice covering my one year old 3/4 acre pond for 2-3 weeks now. The recent warm up has opened up the edges some and I broke up some bigger spots along the edge. I noticed today that about 7-8 large hybrid bluegill were floating under ice. Is it acceptable to expect to lose some fish during periods of ice? I have aeration that was installed this fall but shut it off once water got colder. I only have deep aeration and pond is around 13 feet deep and averages 8 foot probably. What I read On Here was that ponds should be ok in Ohio with that depth and shallow water aeration not needed. Was wondering if I should run a line this spring to the shallow end for winter aeration and leave it run if needed or maybe some dead loss is expected.
Thanks for any help.
