Abstract The embryonic stages of zebrafish Danio rerio (Hamilton, 1822) species were studied from January 2018 to January 2019. The zebrafish, Danio rerio (Hamilton), is one of the most important vertebrate model organisms for scientific researchers. It is very cheapest and breeds large amounts of eggs easily. The genetic structure is surprisingly close to that of Homo sapiens. They have their regenerative power for their fins, skin, heart etc. during their larval stages. In the present study, a totally 30 individuals of sexually matured zebrafish, Danio rerio (Hamilton) were examined in embryonic stage and larval development by placing with the ratio of 2 males: 1 female for their breeding. The water temperature at 25-26°C and pH at 6.8 were managed, respectively. At each time of the breeding process, about 100 eggs were obtained including fertilized and unfertilized eggs. Five replications of embryogenesis in Zebrafish Danio were studied. The development of zygote, cleavage, blastula, gastrula, segmentation, pharyngular and hatching and early larval development were recorded according to the changing of time after fertilization under the light microscope and stereomicroscope by placing the concaving slide. Indeed, the present embryonic study provides a detailed illustration of the development of zebrafish (D. rerio) in nature and the knowledge for future researchers. |
