Predators and food are the keys to understanding fish shoals; synchronised co-operation defeats predators, and optimal food gathering in shoals reflects a shifting balance between joining, competing in, or leaving the group. In the wild, predators may arrive while shoaling fish are feeding, and so vigilance is a crucial behaviour. Once detected, predator defence takes precedence over feeding, since an animal’s life is worth more than today’s dinner.

Fish odour triggers conspecific attraction behaviour in an aquatic invertebrate
TLDR
Without fish odour, the gammarids showed no significant tendency to aggregate, but in fish-conditioned water, they significantly preferred to stay close to conspecifics and Predation risk can, thus, influence gammarid social behaviour.
Social predation in electric eels
TLDR
These findings challenge the hypothesis that electric eels may have a single foraging strategy, and extend knowledge on social predation to an organism that employs high-voltage discharge for hunting, thereby offering a novel perspective for studies on the evolutionary interplay between predatory and escape tactics.
Effects of nutritional state on the shoaling tendency of banded killifish, Fundulus diaphanus, in the field
TLDR
It is concluded that nutritional state seems to affect an individual's decision to continue shoaling once an association has been made, and experimentally state-dependent changes in the size of social groups in fish under field conditions are investigated.
Social behaviour, homing and migration
TLDR
The problems to be solved in survival and reproduction are no less difficult for cyprinids, and their solutions have much to tell us about the evolution of social groups and the individual benefits of co-operation with others.
Information Transfer across Fish Shoals under Predator Threat
TLDR
The hypothesis that shoaling fish can obtain information about a predator's approach from changes in the behaviour of other shoal members was tested and there is clear evidence that receiver fish modify their own behaviour on the basis of information obtained from individuals which have seen a predator.
Early development of shoaling behaviour in larval capelin (mallotus villosus)
The ontogeny of shoaling behaviour in early‐stage larval capelin was examined for larvae raised under different conditions of prey concentration and disturbance. Shoals were evident from the first…
Dicing with death: predator inspection behaviour in minnow shoals
TLDR
Individual minnows which have carried out an inspection visit to the predator model exhibit changes in behaviour on return which are contingent upon the state of the model, demonstrating that information is gained.
Shoaling and Factors Underlying Shoal Composition in Fish Chantima Piyapong
This article reviews group-living of animals, by focusing on shoaling behaviour in fish. It provides a general overview of shoaling behaviour, costs and benefits of this behaviour, and also factors…
Zooplankton patchiness and the associated shoaling response of the temperate reef fish Trachinops taeniatus
TLDR
There may be an optimum shoal size to achieve maximum prey intake, and that shoal location and size may be linked to the distribution of zooplankton prey.
Size-segregative behaviour in minnow shoals
TLDR
The experiment shows that asymmetrical pay-offs in foraging and in response to predator threat are the probable reasons for size-segregation behaviours, and supports the views of earlier workers that mechanical sorting by swimming speed is not an important factor in size segregation in shoals.

Risk of predation and foraging behaviour in shoaling banded killifish (Fundulus diaphanus)
TLDR
Solitary and shoaling banded killifish altered their foraging behaviour to reduce risk of predation in the presence of a predator and appeared to trade off risk of mortality and energy gain.
Predator model recognition and response habituation in shoaling minnows
The effects of increasing shoal size on handling time in Goldfish, Carassius auratus L.
TLDR
Results indicate that handling times for a pellet of food shown by individual members of a shoal of goldfish decrease by some 20% as the number of fish in the shoal increases from two to 15.

Species segregation during predator evasion in cyprinid fish shoals
TLDR
Behaviour which sorted fish into species at the onset of predator attack was revealed, and the value to the individual of segregative behaviour in response to predator threat is discussed.

Adaptive Flexibility in the Foraging Behavior of Fishes
TLDR
Data are presented to show that juvenile coho salmon (Oncorhynchus kisutch) alter their behavior in an adaptive manner when faced with variable degrees of threat of competition from territorial intruders, and of risk of predation.
