Current issues in fish welfare
TLDR
This paper focuses on welfare as the absence of suffering in fish, arguing that complex animals with sophisticated behaviour, such as fish, probably have the capacity for suffer ing, though this may be different in degree and kind from the human experience of this state. Expand
In situ examination of boldness–shyness traits in the tropical poeciliid, Brachyraphis episcopi
TLDR
Fish from high- and low-predation regions within four streams that run independently into the Panama Canal were tested and boldness scores were strongly influenced by standard length and the relative level of predation pressure in the rivers. Expand
Do fishes have nociceptors? Evidence for the evolution of a vertebrate sensory system
TLDR
This study provides significant evidence of nociception in teleost fishes and demonstrates that behaviour and physiology are affected over a prolonged period of time, suggesting discomfort. Expand
Heritable and experiential effects on boldness in a tropical poeciliid
TLDR
First-generation laboratory-reared fish showed similar behaviour to their wild parents suggesting thatboldness has a heritable component, and repeated chasing with a net increased boldness in both high- and low-predation offspring, showing that boldness is also heavily influenced by life experiences. Expand
Size matters: a test of boldness in eight populations of the poeciliid Brachyraphis episcopi
TLDR
The relation between body size and time to emerge from a shelter was positive, with larger fish taking longer to emerge, and the underlying importance of variation in boldness and its effects on other behavioural and life history traits is discussed. Expand
Do Fish Feel Pain
TLDR
Victoria Braithwaite fluently and convincingly describes why the subject of fish pain and suffering has only been recently addressed and acknowledges the paradox that the authors' own existence is so inextricably tied to these “alien”-looking species. Expand
Indirect fitness consequences of mate choice in sticklebacks: offspring of brighter males grow slowly but resist parasitic infections
TLDR
The association with reduced growth suggests a mechanism for the maintenance of heritable variation in both disease resistance and male sexual coloration, and suggests that highly ornamented males confer disease resistance on their offspring. Expand
Environmental enrichment promotes neural plasticity and cognitive ability in fish
TLDR
Exposing fish to enriched conditions upregulated the forebrain expression of NeuroD1 mRNA and improved learning ability assessed in a spatial task, and promotes neural and behavioural changes that are likely to promote behavioural flexibility and improve post-release survival. Expand
The importance of wild populations in studies of animal temperament
TLDR
This review highlights potential problems that arise from using captive animals to elucidate the ecological and evolutionary functions of temperament in wild populations, and stresses the need for measurements of repeatability and heritability, and the importance of biological and ecological validation of temperament tests in wild animals. Expand
The evolution of sex differences in spatial ability.
TLDR
The authors critically review the proposed evolutionary explanations for sex differences in spatial cognition and conclude that most of the hypotheses are either logically flawed or, as yet, have no substantial support. Expand
