both because of the regular spacing that seems to characterize fish in schools and because fish in shoals tend to be uniform in size. To gain hydrodynamic advantages, however, each fish must maintain rather precise positioning within a school to use the hydrodynamic ...
For fish that shoal throughout their lifetimes, little energy has to be expended in finding a mate when spawning time comes. Presumably, shoaling also allows fish to closely synchronize their reproductive cycles (through behavioral and hormonal cues). In addition, for fish that migrate long distanc...

First, antipredator functions and changes in fish shoal parameters caused by predation risk are briefly discussed. Then, effects of parasites that have the potential to act as a force that can select for either larger or smaller group size, or even for solitary behavior are reviewed. Predation-...
Fish in shoals share information by monitoring each other’s behavior. Feeding behavior in one fish quickly stimulates food-searching behavior in others. For planktivores, however, this advantage may be decreased by having to share the patch with many other fish: fish in the rear of a school...
Shoaling is the behavior in which fish aggregate and swim together. If an invasive fish shoals strongly, it should be susceptible to capture using 'Judas' fish, the technique in which individuals are tracked as they locate (and 'betray') other members of their group. This technique is already...

Shoaling behaviorZebrafish\n Danio rerio\nShoaling behavior provides numerous fitness benefits for fish, including enhanced access to mates, increased success in foraging and protection from predators. We were interested in determining whether shoaling intensity differed throughout the day. To do this we...
