What water temperature do perch feed best in?
The comfort band is roughly 17–23 °C (63–73 °F) — a true cool-water fish, slotted between the warm-water bass and the cold-water trout. Metabolism, and therefore feeding, peaks in that band, which at Great Lakes and southern Canadian latitudes means early summer and again in fall. The more useful fact is how wide the working range is: perch feed measurably from near 0 °C (32 °F) under ice up to about 26–27 °C (79–81 °F), so the question is rarely whether they are eating but where the comfortable water is.
