SynopsisWe report the first investigation of the structure of schools of predatory fish, analyzed from aerial photographs of Atlantic bluefin tuna,Thynnus thynnus, in the wild. Internal structure of formations of giant bluefin supports two hypotheses for the formation of predatory fish schools. The parabolic shape of the schools suggests that tuna hunt cooperatively and the position of fish within the schools is such that individuals benefit from hydrodynamical interactions with their neighbors… 
Ontogenetic changes in schooling behaviour during larval and early juvenile stages of Pacific bluefin tuna Thunnus orientalis.
Schooling was first observed at 25-27 days after hatching (26. 2-33. 8 mm, total length) in the Pacific bluefin tuna Thunnus orientalis. At this time, the mode of swimming changed from intermittent

Analysis of foraging movements of Atlantic bluefin tuna (Thunnus thynnus): individuals switch between two modes of search behaviour
The authors' results provide evidence that bluefin tuna attempt to optimize their searching efficiency through adjustments in the duration and timing of switching between these two searching strategies.
Risk of predation, hydrodynamic efficiency and their influence on school structure
Respirometer experiments indicated these fish were capable of achieving some hydrodynamic benefits from schooling but these benefits may be a function of fish size.
Group size affects predation risk and foraging success in Pacific salmon at sea
Group Grouping (schooling, flocking, herding) is broadly distributed across taxa and environments, and is particularly common in marine fishes. A rich body of theory outlines ways in which grouping
A study of Mediterranean bluefin tuna (Thunnus thynnus L.) with reference to stock identification and management strategies
The management of bluefin tuna (Thunnus thynnus) in the north Atlantic has been based on the assumption that there are two separate stocks (an eastern Atlantic stock, including the Mediterranean Sea
Atlantic Bluefin Tuna in the Gulf of Maine, I: Estimation of Seasonal Abundance Accounting for Movement, School and School-Aggregation Behaviour
Direct assessment of the abundance of highly migratory pelagic species, such as tuna, is rarely available and most indices are based on catch information. We estimate the seasonal abundance of North
Seasonal Distribution, Aggregation, and Habitat Selection of Common Carp in Clear Lake, Iowa
Using radiotelemetry to quantify seasonal distribution, aggregation, and habitat selection of adult and subadult common carp in Clear Lake during 2005-2006 in an effort to guide future control strategies, adults demonstrated a clear tendency to aggregate in an offshore area during the late fall and winter and in shallow, vegetated areas before and during spring spawning.
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.


Some Aspects of the Organization of Fish Schools
School organization differed among species at the adult stage; schools of Scomber were typically the most compact and organized; Trachurus and Engraulis schools were intermediate in their organization and Atherinops schools were the least organized.
Evidence against a hydrodynamic function for fish schools
The model proposed by Weihs5,6 for the first time makes precise predictions about school structure which can be verified, and it is demonstrated that three species of schooling fish do not swim in appropriate positions to gain hydrodynamic advantage.
The squid Loligo opalescens forms schools which are similar in many respects to those of obligate schooling fishes and laboratory experiments indicate that the main sensory modality regulating schooling is vision.
Hydromechanics of Fish Schooling

  • 1973
Hydrodynamical effects appear to be important to obligate schooling species, and the endurance of the fish is found to be increased twice to six times when in schools.

Theoretical Effect of Schooling by Planktivorous Fish Predators on Rate of Prey Consumption
This study suggests that schooling of predators occurs at the expense of prey consumption, and there may be some advantage to schooling when prey have a clumped distribution.
An analysis of school structure for tadpoles (Anura: Amphibia)
In the absence of other cues, Bufo and Xenopus tadpoles orient parallel to nearest neighbors under a variety of conditions of density, size, and in both the light and dark, although more strongly in the light.
The three-dimensional structure of fish schools
Methods for producing and analyzing long-term three-dimensional records of the positions of individuals within fish schools are described and shape of cod schools and, to a lesser degree, saithe schools, is shown to be highly variable.
