The Duke University School of Medicine Zebrafish Core Facilities (Z-Core) is a shared resource that offers aquaculture services to nine biomedical research labs using zebrafish as a model organism.  Having gone through several expansions since its inception in 2003, the Duke Z-Core now houses over 12,000 tanks. The facility utilizes seven large multi-rack recirculating aquaculture systems (RAS) and many small RAS units to house thousands of transgenic and mutant zebrafish strains.  The facility staff provides fish husbandry and RAS maintenance in support of studies at the forefront of tissue regeneration, microbiota interaction, morphogenesis, cellular disease, and immunology research.  The Z-Core’s growth and use of advanced aquaculture equipment creates a unique and growth-oriented environment for professionals looking to advance in aquaculture and aquatic science disciplines.


The Z-Core has an immediate opening for a full-time facility technician to be part of a dedicated husbandry staff. Candidates should have at minimum an associate’s degree in a scientific discipline, with a bachelor’s degree preferred.  A general understanding of aquaculture, husbandry, and water chemistry is expected.
