Lower light intensity reduces larval aggression in matrinxã, Brycon amazonicus

Brycon amazonicus shows a high frequency of aggressive behavior, which can be a limiting factor in intensive farming systems. Environmental changes can modulate the social interactions of fish and reduce aggression during the different stages of production. Groups of three...

I3S software as a refinement technique to identify individuals within a captive Scyliorhinus canula population

Demarking individual animals within a group is often required in research. However, the process of invasive tagging induces stress and if a tag becomes detached it may wound the animal and/or prevent identification. Photo identification using natural marks can be...

Effects of different levels of environmental enrichment on the sheltering behaviors, brain development and cortisol levels of black rockfish Sebastes schlegelii

Environmental enrichment is a promising way to increase the fitness and survival of fish released for stock enhancement and biological conservation programs. However, the effects of enrichment in different studies on the fish behavior, physiology and neural development were considerably...

Positive welfare for fishes: Rationale and areas for future study

Traditional animal welfare paradigms have focused on maintaining physical health and mitigating negative impacts to wellbeing. Recently, however, the field has increasingly recognized the importance of positive welfare (i.e., mental and physical states that exceed what is necessary for immediate...

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...

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...

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...

Individual consistency and context dependence in group-size preference of Eurasian perch

Many fish spend a large part of their life in groups. The size of the group influences potential costs and benefits of group living, and depending on context a fish may prefer different group sizes. Group-size preference may also depend...

Assessing husbandry requirements of Zebrafish (Danio rerio) and Medaka (Oryzias latipes) using background literature and comparative information

Zebrafish are the most common species of fish used for research in the UK. However, the species Medaka is establishing itself as a complimentary species to the Zebrafish. Despite having similar husbandry requirements and physiology, there are areas where development...
