Avoiding predation is generally seen as the most common explanation for why animals aggregate. However, it remains questionable whether the existing theory provides a complete explanation of the functions of large shoals formation in marine fishes. Here, we consider how well the mechanisms commonly proposed to explain enhanced safety of group living prey explain fish shoals reaching very large sizes. By conceptually re-examining these mechanisms for large marine shoals, we find little support… 
A meta‐analysis of fish behavioural reaction to underwater human presence
A comprehensive meta‐analysis evaluating FID of fish in response to human presence found that individual fish size was strongly and positively correlated with FID and the most important moderator that explained the variance in individual body size‐FID relationship was shoaling behaviour.
Anthropogenic Marsh Impoundments Alter Collective Tendency in Schooling Fish
Animal groups are known to exhibit collective behaviours that allow for effective responses to predators and environmental factors. Habitats with high levels of structural complexity have been shown
Rheotaxis performance increases with group size in a coupled phase model with sensory noise
It is found that under noisy environmental conditions, increased group size improves rheotactic behavior, and this model has implications for understanding animal behavior, as well as for potential applications in bio-inspired engineering.
Group size affects predation risk and foraging success in Pacific salmon at sea.
Grouping is ubiquitous across animal taxa and environments. Safety in numbers is perhaps the most cited reason for grouping, yet this fundamental tenet of ecological theory has rarely been tested in
Predators attacking virtual prey reveal the costs and benefits of leadership
The results suggest that goal-orientated individuals (i.e., potential leaders) are under selective pressure to maintain group cohesion, favoring effective leadership rather than group fragmentation, which has significant implications for understanding the evolution and maintenance of different social roles in groups.
Social and Ecological Factors Influencing Collective Behavior in Giant Danio
This dissertation focuses on shoaling (aggregating) fish and focuses on two ecologically relevant decision-making behaviors: rheotaxis, or orientation with respect to a flow, and startle response, a rapid response to a perceived threat.


Critical Population Density Triggers Rapid Formation of Vast Oceanic Fish Shoals
By quantifying the formation processes of vast oceanic fish shoals during spawning, it is shown that a rapid transition from disordered to highly synchronized behavior occurs as population density reaches a critical value and general theoretical predictions believed to apply in nature irrespective of animal species are confirmed.
Do Predators 'Shape' Fish Schools: Interactions Between Predators and Their Schooling Prey
Whether safety accrues differentially among school members, and between school members and isolates, depends on: the size and shape of the school, the individual member's behaviour, the 'behaviour' of the group, and, most importantly, the relative frequency and abundance of each predator type.
Confusion of predators does not rely on specialist coordinated behavior
The results suggest that the confusion effect can arise under less specialist circumstances than previously realized, and so the importance of this mechanism in shaping aggregation by prey and predator--prey interactions may be substantially greater than previously considered.
Scale-free correlations in starling flocks
It is suggested that flocks behave as critical systems, poised to respond maximally to environmental perturbations, through scale-free behavioral correlations, which provide each animal with an effective perception range much larger than the direct interindividual interaction range, thus enhancing global response to perturbation.
Inferring the structure and dynamics of interactions in schooling fish
Comparing data from two-fish and three-fish shoals challenges the standard assumption that individual motion results from averaging responses to each neighbor considered separately and finds no evidence for explicit matching of body orientation.
Shapes of Krill Swarms and Fish Schools Emerge as Aggregation Members Avoid Predators and Access Oxygen
Inferring the rules of interaction of shoaling fish
Three key rules for the social interactions of mosquitofish (Gambusia holbrooki) are identified, which are different from the classical models of collective animal motion, raising new questions about how fish and other animals self-organize on the move.
Empirical investigation of starling flocks: a benchmark study in collective animal behaviour
Schools of fish and flocks of birds: their shape and internal structure by self-organization
Models of self-organization have proved useful in revealing what processes may underlie characteristics of swarms and when group size becomes larger, temporary subgroups may increase the complexity of group shape and internal structure.
