Predators select against high growth rates and risk–taking behaviour in domestic trout populations
TLDR
This is the first large–scale field experiment to directly test theory and simultaneously quantify the initial invasibility of domestic salmonid strains that escape into the wild from aquaculture operations, and the ecological conditions affecting their survival.
The role of turbidity as a constraint on predator-prey interactions in aquatic environments
TLDR
The hypothesis that most antipredator behaviour will become ineffective and that predator-prey interactions in turbid water will be primarily characterised by the direct effects of predator consumption of prey, rather than behavioural modification reducing the growth rates of prey is suggested.

TLDR
A review of tests of Tests of ideal free distribution (IFD) theory reveals a characteristic bias: patches with a small proportion of the resources are relatively overused and patches with more than a larger proportion are relatively underused.
Behavioural trade-offs between growth and mortality explain evolution of submaximal growth rates.
TLDR
Whereas rapid growth is beneficial in many ecological interactions, the results show the mortality costs of achieving it are large in the presence of predators, which can help explain the absence of an average phenotype with maximized growth rates in nature.
Sensory compensation and the detection of predators: the interaction between chemical and visual information
TLDR
A simple model is presented which suggests that the combination of risk of predation and information from other sources will determine when fishes should react to chemical alarm cues in water.
Variation in tolerance to hypoxia in a predator and prey species: an ecological advantage of being small?
TLDR
In aquatic ecosystems where smaller fishes are more tolerant to hypoxia than their larger predators, hypoxic environments may have the potential to act as a refuge from predators.
Ontogeny of energy allocation reveals selective pressure promoting risk-taking behaviour in young fish cohorts
TLDR
The results indicate that the size-dependent risk of predation promotes risk-taking behaviour of age-0 trout to increase growth and minimize time spent in vulnerable sizes, and the physiology of energy allocation and behaviour interact to mediate growth/mortality trade-offs for young animals at risk ofpredation and starvation.
The interaction between antipredator behaviour and antipredator morphology: experiments with fathead minnows and brook sticklebacks
TLDR
The data suggest that the morphology of brook sticklebacks and their behavioural sensitivity to predation risk may allow them to efficiently exploit habitats that contain predators.
The foraging and antipredator behaviour of growth-enhanced transgenic Atlantic salmon
TLDR
It is suggested that growth rates of Atlantic salmon may be optimized by the risk of predation, and the genetic manipulation necessary to increase growth rates is achievable through evolutionary change.
Predator–prey interactions and changing environments: who benefits?
TLDR
It is demonstrated that changes in the thermal environment can result in a net benefit to cold-adapted species through the mechanism of predator–prey interactions, indicating that potential implications associated with thermal change are unlikely to be straightforward and may present a greater threat to predators than to their prey.
