Zebrafish are an established and widely used animal model, yet there is limited understanding of their welfare needs. Despite an increasing number of studies on zebrafish enrichment, in-tank environmental enrichment remains unpopular among researchers. This...
Cognitive bias is defined as the influence of emotions on cognitive processes. The concept of the cognitive judgement bias has its origins in human psychology but has been applied to animals over the past 2...
Laboratory fish play an important role in modern scientific research. More and more researchers have begun to pay attention to the other living environment except the physical and chemical factors of the water body, because...
Laboratory fish play an important role in many research fields, and they are also raised and bred in many laboratories around the world. While many studies have suggested suitable feeding densities for various laboratory fish...
Anesthetics are commonly used in fish for surgery and to facilitate capture, handling and transport in aquaculture and experimental procedures. In research, the selection of the anesthetic depends on its properties and on the recovery...
Empirical evidence suggests fishes meet the criteria for experiencing pain beyond a reasonable doubt and zebrafish are being increasingly used in studies of pain and nociception. Zebrafish are adopted across a wide range of experimental...
In fisheries science, chemical anaesthesia and electrical immobilisation are often studied in laboratory or aquaculture settings with little focus on post-release behaviours of fish in the wild. We used nest-guarding smallmouth bass (Micropterus dolomieu) as...
Growing evidence reveals notable phenotypic plasticity in cognition among teleost fishes. One compelling example is the positive impact of enriched environments on learning performance. Most studies on this effect have focused on juvenile or later...
The spotted ratfish Hydrolagus colliei is the most common holocephalan species exhibited in aquaria worldwide for introducing deep-sea environments and raising awareness of their conservation. However, little is known about the biology of H. colliei...
In 2019 the first Zebrafish health and welfare terms database was created. Working in collaboration with Zebrafish specialists and veterinarians we defined severity scores, welfare indicators, definitions and images to form a resource for the...
