Bruce,
I know the trout can as I have run an aerator in deep water in the trout pond with no problems. Could be the the walleye and perch are more tolerant, but it could also be they can handle lower D.O. or a little of both. Trout cannot handle low D.O. very well in most circumstances.
Believe it or not aquaculturists and academics around here are referring to largemouth now as "coolwater" fish. It was not so when I studied fisheries. If you think about it they are a coolwater fish ih contrast to catfish and talapia which have higher optimum temps. I see the AFS now considers the Florida largemouth a different species than the northern largemouth due to DNA analyisis.
