Well over the last 3 to 4 days I have been finding large dead bluegill and observing my largest bluegill struggling here and there. I have been aerating every night from 6PM to 9AM since I am in Southwest Louisiana. I guess it is an oxygen crash but I can't understand how with the aeration. Sad to see the fish I was proudest of to be floating. Not many fish but it is a small pond. Death Toll is at 9 7.5" to 8.5" bluegill. Right now I have changed my aeration to 24/7, is that the right move?
