Abstract
Effects of group size on schooling behavior in two cyprinid fish species
Highlights
Any group of fish that stays together is considered to be shoaling, and if the group swims in the same direction in a coordinated manner, it is said to be schooling (Pitcher & Parrish 1993, Delcourt & Poncin 2012)
The maximum swimming speed for qingbo was recorded in the 8-individual groups, which was significantly higher than the values of the other 2 group sizes, and the swimming speed of 4-individual groups was significantly higher than that of the 2-individual groups (p < 0.05)
The synchronization of speed increased with group size in Chinese bream, whereas it showed no change in qingbo among different group sizes
Summary
Any group of fish that stays together is considered to be shoaling, and if the group swims in the same direction in a coordinated manner, it is said to be schooling (Pitcher & Parrish 1993, Delcourt & Poncin 2012). Fish derive many benefits from living in groups, including defense against predators, enhanced foraging success and improved swimming efficiency (Hemelrijk et al 2015). Fish in the field do not always choose to stay in large groups, suggesting that the benefits of group living are offset by certain costs. How the behavior of individuals, and the interac- interesting information for understanding schooling tions between them, influence group-level behaviors behaviour. Is at the heart of collective behavioral research.
