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

The present study examines whether fish density affects behavioural tests, feed demand, and different parameters indicative of the oxidative status of the liver and brain of Orechromis sp. to identify welfare indicators for fish culturing. The fish were maintained at...

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...

Physiological and behavioural evaluation of common anaesthesia practices in the rainbow trout

Anaesthetic drugs are commonly administered to fish in aquaculture, research and veterinary contexts. Anaesthesia causes temporary absence of consciousness and may reduce the stress and/or pain associated with handling and certain invasive procedures. The rainbow trout (Oncorhynchus mykiss) is a...

Behavioural responses of fish larvae modulated by analgesic drugs after a stress exposure

Fish are known to respond to a wide range of irritant chemicals, displaying clear behavioural changes after exposure to potentially noxious stimuli. Recent evidence shows that these agents can have an impact on larval forms of fish. However, very little...

Free-choice exploration increases affiliative behaviour in zebrafish

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 opportunities available in nature, captive environments can be under-stimulating—with the potential to induce anhedonia and...

Zebrafish welfare: Natural history, social motivation and behaviour

Zebrafish are now one of the most used animal model species in scientific research worldwide. Our current knowledge of wild zebrafish is limited to an estimated range of their natural habitats and their tendencies to form groups. In laboratories, zebrafish...

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,...

Review: Zebrafish environmental enrichment

Recently environmental enrichment for laboratory housed fish has received increasing levels of attention from a variety of interested parties from hobbyists, through animal technologists and aquaculturists, to scientists. Over the last few years, the growth in use of Zebrafish demonstrates...
