Xenopus facility

xenope3 The IBDM Xenopus facility was completely renovated in 2017 thanks to the support of the PACA Region and CNRS. Today, it is equipped with a multi rack system, consisting of a water treatment unit connected to a series of racks that house thirty-six twenty-seven-litre aquariums, ensuring constant micro-environmental conditions and allowing the housing of 300 to 400 individuals of the species Xenopus laevis.

The aquariums are brownish in colour, giving the animals an optimal environment in terms of luminosity, limiting their stress, and inhibiting the growth of algae. The aquariums are arranged on sliding shelves, for better access to the animals and to limit the Musculo-Skeletal Disorders (MSD) of the zootechnicians.

The Xenopus housing system benefits from an automatically controlled maintenance, the water being softened and osmosed.

xenope1Inside the water treatment unit, temperature, pH and conductivity levels are checked and adjusted, if necessary, using the automatic dosing system, as well as a heating/cooling unit. The water then passes through a mechanical cartridge filter and a carbon filter before being sterilized by a UV lamp and distributed to each aquarium. The system operates in a closed circuit, allowing the water to be recycled, thus limiting the ecological and economic impact.

The lighting is set on a 12-hour day-night cycle. The room is thermo-regulated at 20°C all year round.

Animals are fed 3 times per week with pellets designed for aquatic animals.

All of these factors combined with the enrichment of the aquariums (Plexiglas hiding places) limit the stress of the animals and improve their quality of life on a daily basis.

IBDM’s Xenopus facility complies with the European legislation in force (Decree 2010/63/EU).
