Effects of different tank sizes on laboratory rare minnow (Gobiocypris rarus)-Under the same density

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, significant variations exist in the...

Are lateralized and bold fish optimistic or pessimistic?

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 decades. In this study we...

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...

Growth and oxidative stress of clownfish Amphiprion ocellaris reared at different salinities

Aquaculture of ornamental marine fish is often conducted in recirculating aquaculture systems (RAS) using artificial seawater. Considering the cost of salts to produce artificial seawater (salinity 35‰), we investigated the effect of different salinities (5, 15, 25, and 35‰) on...

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...

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...
