Abstract: Diabetes mellitus is a group of metabolic diseases characteized by hyperghycemia.With the economic development and lifestyle changes,the prevalence of diabetes has gradually increased,and it has become an increasingly serious public health problem in most regions of the world.Presenting a heterogeneous etiology,the pathogenic mechanisms of diabetes is still unclear and effective therapeutic methods need to be explored.Studies in animal models are contributing to  understanding of the pathogenic mechanism of diabetes and development of drugs.Zebrafish is superior to other model systems,rapidly emerging as promising model organism for functional studies of human disease，including inducedproximity models and genetically modified models with spontaneous diabetes.This article reviews the progresses of current researches using diabetic zebrafish models.

Key words: diabetes mellitus, zebrafish, animal model, diabetic complications
