Washington State University Zebrafish Facility

The zebrafish (Danio rerio) is the premier non-mammalian vertebrate model organism. Zebrafish have several advantages over other model organisms that include optically transparent embryos, ease of genetic manipulation, sequenced genome, rapid external development, high fecundity, extensive regenerative capabilities, and straightforward husbandry requirements.  This small aquatic fish is utilized in multiple disciplines in over a thousand laboratories around the world because of its biological similarity to humans, its advanced molecular genetics, the elucidation of its genome sequence, and the ever-expanding and outstanding new biological tools now available to the zebrafish researcher.  The advantages of zebrafish provide research opportunities to explore molecular, cellular and systems-level mechanisms to elevate our understanding of human development and diseases.

Our Washington State University-Pullman zebrafish facility is outfitted with a state of the art aquatic systems for fish rearing. Our flow thru system uses reverse osmosis water run through a biological filter (30 and 50 micron filter), and then UV-sterilization, before returning to each tank through an independent valve. The filter system requires minimal maintenance, and maintains high water quality, dramatically reduced disease and mortality. The system automatically senses conductivity, pH, and temperature. In the facility we also do monthly water quality testing.

This system has 2 tank sizes (3.5L and 8L) with the option of nursery tanks being put straight into the system. The fish tanks have an active syphon feature and are blue tinted to help prevent the growth of algae. We have the option of several breeding tanks and systems as well.  For more information contact bmorton@wsu.edu
