Impact of Tank Background on the Welfare of the African Clawed Frog, Xenopus laevis (Daudin)

Despite this, research into the welfare of model amphibian species remains limited. The visual environment is an integral aspect of a captive animal’s housing. Refined cage/tank colour may improve an animal’s visual perception of food items (Strand et al., 2007; Gonzalez-Bernal et al., 2011) and internal cage/tank architecture (Jones and Kaiser, 2005), influence own body colour (Höglund et al., 2002), and provide an increased sense of security in species that rely on crypsis as a means of predator avoidance (Wente and Phillips, 2005).

What Do Zebrafish Want? Impact of Social Grouping, Dominance and Gender on Preference for Enrichment

Although environmental enrichment is known to improve laboratory rodent wellbeing and enhance scientific data collection, relatively little is known with regards to the type of enrichment that might be useful for zebrafish (Danio rerio). Therefore, this study explored if zebrafish displayed preferences for a range of enrichments, including substrates, artificial plants, combinations thereof and airstones.

The Behavioral Effects of Single Housing and Environmental Enrichment on Adult Zebrafish (Danio Rerio)

Although environmental enrichment is known to improve laboratory rodent wellbeing and enhance scientific data collection, relatively little is known with regards to the type of enrichment that might be useful for zebrafish (Danio rerio). Therefore, this study explored if zebrafish displayed preferences for a range of enrichments, including substrates, artificial plants, combinations thereof and airstones.
