Environmental Enrichment

Environmental enrichment impacts discrimination between familiar and unfamiliar human odours in snakes (Pantherophis guttata)

Environmental enrichment has been found to significantly influence the cognitive abilities of a variety of mammalian and avian species, with effects ranging from positive to negative, however, these effects have been little studied in reptiles. This is problematic given their...

Does the provision of environmental enrichment affect the behaviour and welfare of captive snakes?

There is a wealth of evidence demonstrating the benefits of environmental enrichment across a range of different animal species. However, there is comparatively little such research into the effect of enrichment provision on captive reptiles. The aim of this study...

Preference and motivation tests for body tactile stimulation in fish

We tested whether territorial fish (Nile tilapia) perceive body tactile stimulation as a positive or negative resource. Individual male fish were placed for eight days in an aquarium containing a rectangular PVC frame, which was filled with vertical plastic sticks...

A comparative study on two territorial fishes: The influence of physical enrichment on aggressive behavior

Intraspecific aggression is detrimental to body/fin damage, physiological stress, and other problems in aquaculture. Environmental enrichment has been proposed to have positive effects on fish aggressive behavior, physiological stress, and fish welfare, but there are mixed results. Here, we examine...

Effect of environmental enrichment on the brain and on learning and cognition by animals

The humane treatment of animals suggests that they should be housed in an environment that is rich in stimulation and allows for varied activities. However, even if one's main concern is an accurate assessment of their learning and cognitive abilities,...

Report of the 2020 RSPCA/UFAW rodent and rabbit welfare meeting

The RSPCA/UFAW rodent and rabbit welfare group has held a one-day meeting every autumn for the last 27 years, so that its members can discuss current welfare research, exchange views on welfare issues and share experiences of the implementation of...

Enrichment for laboratory zebrafish—A review of the evidence and the challenges

Good practice for the housing and care of laboratory zebrafish Danio rerio is an increasingly discussed topic, with focus on appropriate water quality parameters, stocking densities, feeding regimes, anaesthesia and analgesia practices, methods of humane killing, and more. One area...

Neurobehavioral effects of restricted and unpredictable environmental enrichment in rats

To study how motivational factors modulate experience-dependent neurobehavioral plasticity, we modify a protocol of environmental enrichment (EE) in rats. We assumed that the benefits derived from EE might vary according to the level of incentive salience attributed to it. To...

A novel dietary restriction method for group-housed rats: Weight gain and clinical chemistry characterization

Laboratory rodents are usually fed ad libitum. Moderate dietary restriction decreases mortality and morbidity compared with ad libitum feeding. There are, however, problems in achieving dietary restriction. Traditional methods of restricted feeding may interfere with the diurnal rhythms of the...

Living with low environmental complexity increases fear indicators in Nile tilapia

Animals are often kept in conditions with low environmental complexity and for long periods in barren artificial environments. This has been shown to lead to poor welfare in many species of animals. We assessed the emotional responses of Nile tilapia,...
