The interplay between aerobic metabolism and antipredator performance: vigilance is related to recovery rate after exercise [PDF]

, 2015
When attacked by a predator, fish respond with a sudden fast-start motion away from the threat. Although this anaerobically-powered swimming necessitates a recovery phase which is fueled aerobically, little is known about links between escape performance
