Zebrafishology, study design guidelines for rigorous and reproducible data using zebrafish

The zebrafish (Danio rerio) is one of the most widely used research model organisms funded by the United States’ National Institutes of Health, second only to the mouse. Here, we discuss the advantages and unique qualities of this model organism. Additionally, we discuss key aspects of experimental design and statistical approaches that apply to studies using the zebrafish model organism. Finally, we list critical details that should be considered in the design of zebrafish experiments to enhance rigor and data reproducibility. These guidelines are designed to aid new researchers, journal editors, and manuscript reviewers in supporting the publication of the highest-quality zebrafish research. A review emphasizes the advantages of using zebrafish in research, outlines key differences in experimental approaches, and offers guidelines for designing studies in a way that enhances experimental rigor and reproducibility.
