Individual Behavioural Strategies Associated with Predator Inspection in Minnow Shoals
When confronted with a live pike, Esox lucius, European minnows, Phoxinus phoxinus, showing individual differences in rate of predator inspection, fish with high inspection rates were bolder, skittered more frequently and fed more persistently than fish with low inspection rates.
Dicing with death: predator inspection behaviour in minnow shoals
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.
Predator inspection behaviour in minnow shoals: differences between populations and individuals

Individual differences in inspection found within the two populations suggest that selfish behaviour was present in minnows sympatric with pike.
Habituation of Predator Inspection and Boldness in the Guppy (Poecilia reticulata)
This study examined habituation of the predator inspection behavior in the guppy ( Poecilia reticu- lata ) and its relationship with boldness (open field locomotion). Two different strategies were
Functions of Shoaling Behaviour in Teleosts
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
Species segregation during predator evasion in cyprinid fish shoals
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.
Provenance, shoal size and the sociobiology of predator-evasion behaviour in minnow shoals

Mnows from provenances with and without pike exhibited a similar repertoire of antipredator behaviour patterns, but those sympatric with the predator integrated their tactics more effectively and regained pre-exposure behaviour sooner after each encounter.
Preferences for familiar fish do not vary with predation risk in the European minnow
In the near-natural conditions of a fluvarium in the River Frome, U.K., European minnows Phoxinus phoxinus displayed schooling preferences for familiar conspecifics, despite the antipredator benefits afforded to individual members of schools of familiar fish.
Predator inspection behaviour in three-spined sticklebacks (Gasterosteus aculeatus): body size, local predation pressure and cooperation
It is confirmed that levels of predator inspection are both population- and situation-dependent, suggesting a trade-off in the potential costs and benefits of this behaviour.


Influence of a predator on the optimal foraging behaviour of sticklebacks (Gasterosteus aculeatus L.)
Three-spined sticklebacks' foraging behaviour changes such that they attack swarm regions of lower density which provide a lower feeding rate but should increase their ability to detect an approaching predator, predicted by a model using Pontryagin's principle of maximisation.
Constraints Placed by Predators on Feeding Behaviour
There is a high selection pressure to feed most efficiently in order to grow quickly in teleost fish, which is a good strategy for escaping the prey spectrum of many predators and for increasing reproductive success.
Individual Differences in Fish Behaviour
Fish behaviour, where most students begin by looking at the stereotyped response of the breeding male stickleback to things coloured red (Tinbergen 1951), reveals pronounced individual differences in the rate at whichmale sticklebacks attack red dummies.
Some ecological consequences of fish school volumes
It is shown that roach schools in one river are constantly within attack range of pike predators, and theories which assume that schools function strategically merely to reduce the probability of encountering a predator, break down.
The Annual Food Consumption and Prey Preferences of Pike (Esox lucius) in the River Frome, Dorset
The proportion of food used for maintenance by each age-group increased from 24.3% at age 1 to 77.5% atage 10 years, and it is suggested that, in game fisheries, the removal of coarse fish is suggested.
Some ethical issues raised by studies of predation and aggression
Cost of prey capture, growth rate and ration size in pike, Esox lucius L., as functions of prey weight
The data show that feeding behaviour can have a direct influence on the reproductive success of pike through its effect on growth rate, and the most profitable prey need only be available once every 84 min for pike to maximize their net energy gain.
