When do perch abandon the weeds in fall?
When the weeds stop being worth it. As water falls through the low teens °C (mid-50s °F), shallow vegetation browns and dies, its invertebrate larder thins, and decaying weed actually consumes oxygen instead of making it — so the flats that fed the school all summer go quiet from the inside out. Schools slide down the weedline to the deep edge first, then out onto bare flats and shell beds in 6–12 m (20–40 ft). The tell is green versus brown: the last living green weed patches hold the last shallow fish, and once they brown, the basin has everyone. At Canadian latitudes this runs late September into October; further south it stretches weeks later.
