The Zebrafish Facility

_{The zebrafish facility consists of one large fish room and two microscopy rooms. The fish room houses eight separate tank systems, adding up to nearly 2000 tanks which, at full capacity, can house over 25,000 adult fish. These eight systems are re-circulating and fully quarantined. The facility features its own reverse osmosis (RO) water purification system, which consists of 2 x 1000 litre holding tanks. Approximately 800 litres of RO-water is distributed between the eight tank systems every day and mixed with the circulating water, which flows through bio-filters, mechanical filters and UV-radiation before returning to the header tanks which distribute water to all of the fish tanks. Water quality and temperature are monitored every day and extensive water quality tests are carried out regularly.}

_{The microscopy rooms house two microinjection stations, three stereomicroscopes and 2 fluorescence microscopes. A large incubator for zebrafish embryos is also kept here, at a steady 28°C and with adjustable lighting conditions.}

_{The facility maintains three strains of wild type zebrafish (Danio rerio); Tübingen AB (TAB) and spotty wild type (SWT). In addition, a number of research groups create and maintain a variety of transgenic zebrafish lines which are also kept in the facility. We also house a modest stock of wild type medaka (Oryzias latipes) which may be used as a model organism by researchers and students.} 

_{Important note!!}

 _{According to §12+13 in the Norwegian Regulation on Animal Experimentation, one must have undertaken an approved course in Lab Animal Science (Felasa, MedVet etc.) in order to be granted access to the zebrafish facility.}
