【 摘 要 】

The aim of this paper is to emphasize the main aspects of the ways in which lightinfluences the development of zebra fish (Danio rerio) embryos.During the experiments 3 variants with natural light, continuous light and totally darkwere used to monitor the development of zebra fish embryos in 40 ml Nunk culturedishes at optimum density (1 embryo/ 3 ml) and at 28,5oC temperature.It could be noticed that most embryos died in continuous light medium (57%). Thismeans that such mediums are not suitable to embryos’ development. For the controlvariant (natural light) it was recorded the lowest mortality rate of only 17% and intotally dark variant the mortality was of 40%.Researches on the influence of light on zebra fish embryo development showed that themost suited medium for supporting, growing and developing the Danio rerio embryosit the medium having natural light.
