Zebrafish is the only peer-reviewed journal dedicated to the central role of zebrafish and other aquarium species as models for the study of vertebrate development, evolution, toxicology, and human disease.Due to its prolific reproduction and the external development of the transparent embryo, the zebrafish is a prime model for genetic and developmental studies. While genetically more distant from humans, the vertebrate zebrafish nevertheless has comparable organs and tissues, such as heart, kidney, pancreas, bones, and cartilage.Zebrafish introduced the new section TechnoFish, which highlights these innovations for the general zebrafish community.TechnoFish features two types of articles:TechnoFish Previews: Important, generally useful technical advances or valuable transgenic linesTechnoFish Methods: Brief descriptions of new methods, reagents, or transgenic lines that will be of widespread use in the zebrafish communityZebrafish coverage includes:Comparative genomics and evolutionMolecular/cellular mechanisms of cell growthGenetic analysis of embryogenesis and diseaseToxicological and infectious disease modelsModels for neurological disorders and agingNew methods, tools, and experimental approachesZebrafish also includes research with other aquarium species such as medaka, Fugu, and Xiphophorus.
