Try in a little more shallow for perch this early, around points and known weed bed areas. Oxygen levels here should still be a lil higher due to vegetation, especialy if south facing. Deeper of course as the season continues... and move, move, move! If your using electronics have a buddy drill while you check for fish. When you find them, make swiss cheese around there and hit it hard, that way when the school moves you can move with them. Somedays its fun to just sit and wait for them while you get a tan but being aggressive will typically ice more fish! Good Luck
