Minnows become nocturnal at low temperatures
Juveniles of several species of salmonid become almost exclusively nocturnal in winter. Their diel activity schedule is determined mainly by temperature, with the fish seeking shelter increasingly during the day as the temperature drops. Through controlled laboratory experiments, it is demonstrated...
