Simple Summary The circadian system synchronizes physiology and behavior to predictable
environmental variations (daily cycles in light, temperature, or food availability). To this …

Estimating individual feed intake of fish held in groups has long been a challenge
precluding precise knowledge of the individual variation of feed efficiency (FE) in fish. In this …

To assess mechanisms relating to food intake and glucosensing in fish, and their interaction
with stress, we evaluated changes in the expression of orexigenic (NPY) and anorexigenic …

The relatively easy access to fish worldwide, alongside the increase of aquaculture
production contributes to increased fish consumption which result in higher prevalence of …

In all vertebrates, the regulations of growth and energy balance are complex phenomena
which involve elaborate interactions between the brain and peripheral signals. Most …

When Atlantic salmon parr migrate from fresh water towards the sea, they undergo extensive
morphological, neural, physiological and behavioural changes. Such changes have the …

To assess the effects of subordinate social status on digestive function, metabolism, and
enzyme activity in salmonid fish, juvenile rainbow trout Oncorhynchus mykiss were paired …

Hydrogen sulfide (H 2 S) related mass mortality events in land-based recirculating
aquaculture systems (RAS) are associated with the sudden release of substantial amounts …

To assess whether the brain's monoaminergic and/or corticotropin-releasing factor (CRF)
systems may be involved in mediating the appetite-suppressing effects of high …

This Chapter summarises recent research on the interrelationships between social
behaviour and physiology in fish, discussing the physiological factors that determine social …
