Zebrafish maintenance conditions affect behavioral and biochemical biomarkers: A possible interfering factor on the research results

Over the years, scientific research with fish models has grown at a rapid pace, and issues such as animal welfare are becoming increasingly important in various areas of animal husbandry and experimentation. Here, we evaluated whether Danio rerio behavior is...

The effect of preference assessment-informed enrichment device colour on biting and foraging behaviour in loggerhead sea turtles

Although environmental enrichment procedures have demonstrated their benefit to non-human animals in zoos and aquariums, the field has given little attention to phylogenetic variables that might affect their efficacy. Recently, research with loggerhead sea turtles Caretta caretta has demonstrated that...

What are the priority welfare issues facing parrots in captivity? A modified Delphi approach to establish expert consensus

Parrots (Psittaciformes) are widely kept in captivity, yet their welfare is under-researched in comparison to other captive species. This study aimed to determine key welfare issues affecting parrots through a modified Delphi approach. Twenty-eight welfare issues were first compiled via...

Evaluating enrichment use in group-housed rhesus macaques (Macaca mulatta): A machine learning approach

Environmental enrichment programmes are widely used to improve welfare of captive and laboratory animals, especially non-human primates. Monitoring enrichment use over time is crucial, as animals may habituate and reduce their interaction with it. In this study we aimed to...

Structural enrichment promotes natural behaviour and welfare of captive gilthead seabream broodstock

The intensification of aquaculture practices in the last decade can compromise the welfare of farmed fish. However, one strategy to be considered to improve the welfare of captive fish is the implementation of structural enrichment in the rearing environment. The...

Evaluating indicators of wellbeing in captive grey mouse lemurs, Microcebus murinus, in the context of enrichment

Developing and implementing effective approaches to improve the welfare of animals participating in research requires reliable monitoring of their wellbeing. Since wellbeing is a multidimensional state that relates to an individual's physiological, behavioural and psychological/mental health, assessing it requires the...

The voice of choice: A scoping review of choice-based animal welfare studies

“Choice and control” is a phrase used widely in animal welfare science to describe providing captive animals with the ability to select between possible outcomes (stimuli or events). This concept has gained traction as a pivotal management technique across a...

Exploring pet rat care: A comprehensive survey of husbandry, health, behavior, and the associations between caretaker attitudes, attachment, and husbandry practices

Pet rats are still understudied in terms of animal welfare and human-animal interaction research. An extensive online survey targeting German-speaking rat caretakers was conducted (n = 978). One of the study's goals was to investigate husbandry practices, health indicators, rat...

Novel scent enrichment enhances socio-sexual and olfactory behaviors in zoo-housed gentle lemurs

The Alaotran gentle lemur (Hapalemur Alaotrensis) is one of the most endangered primates in the world and shows a low success rate in captive breeding programmes. We tested a novel scent enrichment, made up of a synthesized mixture likely conveying...
