Pebble to the metal: A boulder approach to enrichment for Danio rerio

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 is due to perceived concerns...

Pain management in zebrafish: Report from a FELASA Working Group

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 fields and their use is...

Environmental conditions shape learning in larval zebrafish

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 life stages, potentially overlooking the...

The zebrafish health and welfare database, where we are now

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 Zebrafish community. Since then the...

Comparative study of tricaine methanesulfonate (MS-222) and eugenol as euthanasia agents in zebrafish (Danio rerio) as an experimental model

In experimental procedures inevitably leading to the sacrifice of animals, suitable measures should be taken to minimise their pain and suffering as much as possible, as well as to prevent any modification or masking in the experimental results obtained. An...

Effects of different handling methods on the behavior of adult zebrafish

The zebrafish is an important biomedical research organism. In most research, zebrafish are removed from their home tank and subsequently their phenotype is measured. The method of handling the fish, however, may significantly affect a variety of phenotypes. This is...

Laboratory-based measures of temperature preference and metabolic thermal sensitivity provide insight into the habitat utilisation of juvenile California horn shark (Heterodontus francisci) and leopard shark (Triakis semifasciata)

Laboratory-based studies examining fish physiological and behavioural responses to temperature can provide important insight into species-specific habitat preferences and utilisation, and are especially useful in examining vulnerable life stages that are difficult to study in the wild. This study couples...

Comparison of tricaine methanesulfonate (MS-222) and alfaxalone anesthesia in zebrafish (Danio rerio)

The research use of zebrafish has risen exponentially over the past decade while anesthetic options have remained largely unchanged.6 ricaine methanesulfonate (MS-222) is widely accepted as an anesthetic for routine husbandry procedures, however it has limitations and safety concerns. 11...

Zebrafish (Danio rerio) distinguish between two human caretakers and their associated roles within a captive environment

Zebrafish have become a popular biomedical model in recent decades, and are now maintained in laboratories worldwide. However, living within a captive environment can introduce novel environmental stressors and experiencing stress chronically can negatively affect animal welfare and, if applicable,...
