In situ examination of boldness–shyness traits in the tropical poeciliid, Brachyraphis episcopi
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
The future of stock enhancements: lessons for hatchery practice from conservation biology
Conservation reintroduction techniques including environmental enrichment, life-skills training, and soft release protocols are reviewed and it emerges that many of the methods examined could be implemented by hatcheries with relative ease and could potentially provide large increases in the probability of survival of hatchery-reared fish. Expand
Social learning and life skills training for hatchery reared fish
New methods and recent findings are reviewed that suggest how social learning protocols could realistically be applied on a large scale to enhance the viability of hatchery fish prior to their release into the wild. Expand
Heritable and experiential effects on boldness in a tropical poeciliid
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
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
Social learning in fishes : a review
Animals acquire skills and knowledge from other animals, and fish are no exception. There is now strong experimental evidence that many species of fish exhibit social learning and traditionalExpand
Fish intelligence, sentience and ethics
The current state of knowledge of fish cognition is reviewed starting with their sensory perception and moving on to cognition, revealing that fish perception and cognitive abilities often match or exceed other vertebrates. Expand
Environmental enrichment and prior experience of live prey improve foraging behaviour in hatchery-reared Atlantic salmon
The assertion that the provision of enriched environments in combination with exposure to live prey prior to release may significantly improve the post-release survival rates of hatchery-reared fishes is supported. Expand
Correlation between boldness and body mass in natural populations of the poeciliid Brachyrhaphis episcopi
The boldness of individual Brachyrhaphis episcopi, collected from regions of high and low predation, was investigated using two independent assays, revealing a strong correlation between the time to emerge from cover and the propensity to leave shoal mates and investigate a novel object. Expand
The influence of early experience on, and inheritance of, cerebral lateralization
Cerebral lateralization refers to the lateralized partitioning of cognitive function in either hemisphere of the brain. Using a standard detour test, we investigated lateralized behaviour inExpand
