APPLIED RESEARCH ABSTRACT The Zebrafish International Resource Center has been established as a repository that provides animals, materials, and services to the research community. The Applied Research Core will research feeding strategies for commercially available and laboratory defined standard reference diets and we will determine the long-term effects of diets, feeding regimen, and an optimized protein:lipid ratio on zebrafish husbandry. These goals will support ZIRC and research community husbandry goals
