Embryos of externally fertilized fish species are directly exposed during their development to environmental conditions that may damage their DNA, such as pollutants, UV light and reactive oxygen species. To deal with such DNA damages, a variety of different DNA repair pathways are employed by fish embryos during their development. In recent years zebrafish have become a useful model for assessing environmental pollutants that might be genotoxic, i.e. cause DNA damage.
