Effects of familiarity on individual growth and feeding behaviour of European seabass Dicentrarchus labrax

Available literature indicates that fish are able to recognize familiar conspecifics and that familiarity may offer important benefits (e.g. more stable social environment, improved foraging behavior, growth, survival). In the practice of intensive rearing of European seabass Dicentrarchus labrax mixing...

A novel emotional and cognitive approach to welfare phenotyping in rainbow trout exposed to poor water quality

Recent scientific evidence for fish sentience has stressed the need for novel sentience-based detection tools of fish welfare impairment in commercial farms. In order to mimic a well-characterised stress situation, rainbow trout (Oncorhynchus mykiss) were exposed to poor water quality...

Body condition scoring for adult zebrafish (Danio rerio)

Body condition scoring (BCS) is a simple, rapid, noninvasive tool used to assess body condition in animals. In this study, we developed and validated a diagram-based BCS for adult zebrafish (Danio rerio), a popular research model. After receiving 20 min...

Tactile stimulation reduces aggressiveness but does not lower stress in a territorial fish

Body tactile stimulation has a positive effect upon highly social animals, such as mammals and cleaner-client coral-reef fish, by relieving stress and improving health. Conversely, some tactile contacts are naturally detrimental, such as those resulted from aggressive interactions. To study...

In-tank underwater cameras can refine monitoring of laboratory fish

Laboratory animals need to be monitored to check the status of their health and welfare. Routine checks of laboratory fish are limited to visual observations of physical appearance and behaviour, but for species held in opaque-walled tanks, such checks are...

Is heightened-shoaling a good candidate for positive emotional behavior in zebrafish?

Zebrafish, a highly-social species of freshwater fish, are widely studied across many fields of laboratory science including developmental biology, neuroscience, and genomics. Nevertheless, as standard housing for zebrafish typically consists of small and simplistic environments, less is known about their...

Impact of analgesic drugs on the behavioural responses of larval zebrafish to potentially noxious temperatures

Recent studies have demonstrated that fish exhibit behavioural responses to noxious stimuli, including mechanical, chemical or thermal stimulation. In many cases, these responses are characterised by a reduction in the locomotor activity, which in turn can be ameliorated by using...

Exploring the efficacy of immersion analgesics in zebrafish using an integrative approach

Home Office guidelines recommend the use of analgesics for all protected species, including fish during scientific procedures likely to result in pain, suffering, distress and lasting harm. In larger fish species some drugs have shown efficacy in terms of perioperative...

Effects of culture densities on feed demand, behavioural tests and on the hepatic and cerebral oxidative status in tilapia (Oreochromis sp

Less water renewal reduces effects on social aggression of the cichlid Pterophyllum scalare

Changes in aquatic environments can affect fish behavior. Water renewal, for example, can dilute chemical signals, which are a social communication tool used by some fish species, and this dilution increases aggressive interactions in the group. Fierce and prolonged fights...
