[1] [a] Although shoaling fish can relate to each other in a loose way, with each fish swimming and foraging somewhat independently, they are nonetheless aware of the other members of the group as shown by the way they adjust behaviour such as swimming, so as to remain close to the other fish in the group. Shoaling groups can include fish of ...
Strategies such as those outlined in the previous section can work to a degree against freely streaming fish schools, but work much better if the fish school is first compacted into a bait ball. It is difficult for predators working individually to scare a fish school into a bait ball, and they usually work together.
Shoaling – describes the behaviour of fish which aggregate together, including mixed species groups. Fish derive many benefits from shoaling behaviour including defence against predators through better predator detection and by diluting the chance of capture, enhanced foraging success, and higher success in finding a mate.

Forage fish, also called prey fish or bait fish, are small pelagic fish that feed on planktons (i.e. planktivores) and other small aquatic organisms (e.g. krill). They are in turn preyed upon by various predators including larger fish, seabirds and marine mammals , this making them keystone species in their aquatic ecosystems .
A flock of auklets exhibit swarm behaviour. Swarm behaviour, or swarming, is a collective behaviour exhibited by entities, particularly animals, of similar size which aggregate together, perhaps milling about the same spot or perhaps moving en masse or migrating in some direction.
