The overall purpose of the Stages of Embryonic Development of Zebrafish experiment was to provide in-depth documentation on the different stages that a zebrafish undergoes throughout its growth as an embryo. The main idea of the article is to propose the embryonic development of zebrafish in an efficient and intuitive manner known as stages. In this case Kimmel et al didn’t look to resolve any questions, but sought to improve the current portrayal of the zebrafish embryonic development. In the article, staging has the potential to get rid of any discrepancies between different species regardless of time. Instead of using time, staging takes note of the morphological features that an organism is going through and in-depth descriptions of these stages assist with identification. The reason why this is important is because a wide variety of embryos develop at different rates even from the same clutch. This is due to zebrafish developing asynchronously.

A dissecting microscope was used to examine the current stage that the zebrafish embryo were in. Next, a compound microscope assisted with finding the details that were not visible to the naked eye and the dissecting microscope. In order to prevent the zebrafish from moving, anaesthesia was used. Photographs of the zebrafish were taken periodically using a Kodak Ektachrome 160T DX. The temperature and the time of development was recorded and compiled into various graphs noting the hours of development and the current stage that they were in. Finally, the process was repeated as the zebrafish was going through its different stages. As a result, the stages and the in-depth descriptions were produced along with photographs and drawings to easily distinguish between the different
