What does a summer day look like for a perch school?
Like cattle crossing a pasture. Feeding starts after sunrise, and the school grazes across the flat as a loose front, tipping nose-down to vacuum midge larvae, scuds, and young-of-year minnows off the bottom; a school found at 9 a.m. may be several hundred meters away by noon. Peaks come mid-morning and again mid-to-late afternoon, with smaller fish on the 2–6 m (6–20 ft) weed flats and the bigger fish on deeper flats and shell beds of 6–12 m (20–40 ft), especially in high summer. At dusk everything stops, the school disbands, and the fish sit out the night near bottom.
