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...
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...
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...
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...
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...
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...
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...
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...
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...
The average survival rate for our Zebrafish (ZF) embryos was 65%. When it was time to create our next generation of Wild Type (WT) (used for embryo production), we decided to run a trial focussing...
