Temperament describes the idea that individual behavioural differences are repeatable over
time and across situations. This common phenomenon covers numerous traits, such as …

This review examines the contribution of research on fishes to the growing field of
behavioural syndromes. Current knowledge of behavioural syndromes in fishes is reviewed …

Recent progress has been made on the study of personality in animals, both from a
mechanistic and a functional perspective. While we start knowing more about the proximal …

Farmed fishes are often selectively bred for desirable production traits, such as rapid growth,
that brings with them behavioural differences. In addition, the striking differences in the …

Endocrine disrupting chemicals (EDCs) enter aquatic ecosystems through discharged
effluents, mainly from wastewater treatment works and diffuse run off from land, and affect a …

Social interactions in small groups of juvenile rainbow trout (Oncorhynchus mykiss) lead to
the formation of dominance hierarchies. Dominant fish hold better positions in the …

Studies of fish behaviour have demonstrated the existence of social interactions that result in
dominance hierarchies. In environments in which resources, such as food, shelter and …

Consistent individual differences in behaviour have been described for several species of
salmonid fish, the group that has been most intensively farmed. In particular, fish accept …

Studies of the fitness consequences of behavioral types often focus on isolated behaviors
and ignore potential across-context correlations that may affect fitness. This approach leads …

Animals often prefer areas containing physical structure, and population density often
increases with structural complexity, presumably because physical complexity in habitats …
