We have only taken some 16 to 18 in catfish out. we thought this winter it might be time to take some bluegills. After reading many of the posts we decided to try and use the slot method. Only take bluegill between 4 and 7 inches and cats over 18. We have been concerned about the coppernose though with the cold winter tempatures. We have a Koender windmill and have made the decision to not aerate this winter. We have read the many post on winter aeration and water tempatures and feel that the warmer deep water would be beneficial to the coppernose. This winter so far has been mild, with no ice as of yet. I would like to hear from anyone else in the northern states who might have coppernose.
