Across species, animals organize into social dominance hierarchies that serve to decrease
aggression and facilitate survival of the group. Neuroscientists have adopted several model …

Social status is recognized as a major determinant of social behavior and health among
animals; however, the neural circuits supporting the formation and navigation of social …

The organization of the brain serotonergic system appears to have been highly conserved
across the vertebrate subphylum. In fish as well as in other vertebrates, brain serotonin (5 …

In order to investigate the effects of hypoxic periods on the feeding behaviour and
physiology of Atlantic salmon (Salmo salar L.) post-smolts (237±7g), fish were kept at …

Aquaculture is the fastest growing animal producing sector in the world and is expected to
play an important role in global food supply. Along with this growth, concerns have been …

Signalling systems activated under stress are highly conserved, suggesting adaptive effects
of their function. Pathologies arising from continued activation of such systems may …

Dominance-based social hierarchies are common among teleost fishes. The rank of an
animal greatly affects its behaviour, physiology and development. The outcome of fights for …

Theory suggests that habitat structure and population density profoundly influence the
phenotypic development of animals. Here, we predicted that reduced rearing density and …

Background Fish telemetry using electronic transmitter or data storage tags has become a
common method for studying free-swimming fish both in the wild and in aquaculture …
