Many studies highlighted that gravel is a preferred enrichment of zebrafish, therefore we were keen to explore this anecdotal evidence further, to ascertain if the spatial distribution of the zebrafish was significantly linked to the...
Zebrafish (Danio rerio) is a widely used vertebrate animal for modeling genetic diseases by targeted editing strategies followed by gross phenotypic and biomarker characterization. While larval transparency permits microscopic detection of anatomical defects, histological adult...
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...
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...
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...
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...
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 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...
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...
The zebrafish (Danio rerio, Hamilton, 1822) is one of the most important fish model species in scientific research, with millions of fish housed in laboratory animal facilities around the world. During husbandry, it is necessary...
