Survey of current techniques in the care and maintenance of the African clawed frog (Xenopus laevis)

Amphibians are becoming increasingly popular models in biological research. Until 1989, Rana was the most commonly used anuran genus, but this has now been surpassed by Xenopus. The best way to raise Xenopus spp., to maximize growth and reproduction, has not been established. A survey of 66 research laboratories that maintain a Xenopus laevis colony revealed no consistent protocol for the care and maintenance of these frogs. In addition to the survey, a thorough review of the literature regarding the care and maintenance of Xenopus spp. was conducted. Husbandry practices described in the literature were then compared to the data from the survey. As with the survey, the literature revealed little consistency among Xenopus husbandry practices.
