When water temperatures fluctuate strongly in summer, the water heats up significantly during the day and loses the ability to store oxygen. At night, plants and animals consume the remaining oxygen. In the morning, there is then a critical oxygen deficiency that forces fish into life-saving "emergency breathing" at the surface. During breeding season, birds like herons shamelessly exploit this behavior because the fish are unable to escape and are easy prey.When water temperatures fluctuate strongly in summer, the water heats up significantly during the day and loses the ability to store oxygen.

Nachts verbrauchen Pflanzen und Tiere den restlichen Sauerstoff. Morgens herrscht dann eine kritische Sauerstoffunterversorgung, die Fische in die lebensrettende „Notatmung“ an der Oberfläche zwingt. Zur Brutzeit nutzen Vögel wie Reiher dieses Verhalten schamlos aus, da die Fische fluchtunfähig und leichte Beute sind.
