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...

DNA sampling by skin swabbing for Zebrafish (Danio rerio) and sticklebacks (Gasterosteus aculeatus)

Fin clipping of live fish under anaesthesia is widely used to collect tissues samples for DNA extraction. However, this technique raises a number of ethical concerns, since the use of anaesthetic and/or physical fin damage may cause behavioural changes, pain,...

Use of tricaine methanesulfonate or propofol for immersion euthanasia of goldfish (Carassius auratus)

OBJECTIVE To substantiate current AVMA guidelines for immersion euthanasia of goldfish (Carassius auratus) with tricaine methanesulfonate (TMS), determine whether immersion in propofol at 5 times its immersion anesthesia concentration for 30 minutes is sufficient for euthanasia of goldfish, and quantify...

Uses and doses of local anesthetics in fish, amphibians, and reptiles

Local anesthetics are an integral part of routine pain management in mammals, yet their use is relatively limited in fish, amphibians and reptiles. These animals frequently undergo potentially painful surgical procedures and therefore could possibly benefit from those drugs. Some...
