When observed in their preferred environments, animals display behavioural changes, such
as an increase in resting or a reduction in agonism, suggestive of positive affect and …

Despite generations of rearing in a laboratory environment, zebrafish (Danio rerio) retain
innate preferences for environmental features that mimic their natural habitat (eg plants and …

Simple Summary Despite increasing interest in fish welfare, we still know very little about
positive emotions in fish. This study had two aims:(1) to characterize a previously …

Testing animals in groups can provide valuable data for investigating behavioural stress
responses. However, conventional measures typically focus on the behaviour of individual …

Behavioral assays of zebrafish shoaling have recently been employed to investigate social
behavior in zebrafish models of psychiatric disease. Many studies have developed …

The zebrafish has become a major model system for biomedical research and is an
emerging model for the study of behaviour. Although adult zebrafish express a visually …

Zebrafish (Danio rerio) have an innate tendency to join shoals. Based on this, we refined
visual choice tests to focus on social interaction and novelty preference. Our design follows …

Collective behavior is ubiquitous among fish, yet, its hows and whys are yet to be completely
elucidated. It is known that several environmental factors can dramatically influence …

Cognitive stimulation has been shown to be rewarding and capable of eliciting positive
emotions in several species. In contrast to the abundant learning and exploration …

Social context may influence the perception of sensory cues and the ability to display refined
behavioral responses. Previous work suggests that effective responses to environmental …
