Abstract. Vibration exposure represents a complex mechanical stressor capable of triggering oxidative imbalance, inflammation, and neurophysiological alteration. The zebrafish (Danio rerio), with its strong genetic homology to humans and experimental versatility, offers an ethically responsible and translational model for investigating these molecular effects. This review synthesizes current evidence on vibration-induced oxidative stress while highlighting the ethical frameworks that must accompany such investigations. Within the molecular domain, recent studies demonstrate that controlled vibration activates redox pathways involving mitochondrial dysfunction, reactive oxygen species generation, and Nrf2-mediated antioxidant responses. Advances in molecular assays and omics technologies now permit detailed mapping of these biochemical events at organismal resolution. Parallel to these scientific developments, the moral dimension of zebrafish experimentation demands adherence to the principles of Replacement, Reduction, and Refinement (3Rs), together with transparent welfare monitoring and humane endpoints. Integrating ethical responsibility with molecular precision defines a new paradigm in vibration research—one that unites biological insight with moral accountability and strengthens the translational bridge between laboratory discovery and human occupational health.
Keywords: Zebrafish, oxidative stress, vibration exposure, bioethics, ROS, Nrf2, molecular-biology methods, translational research.
