Zebrafish (Danio rerio) are an important model organism that is particularly valuable for research in developmental biology. Zebrafish are extremely fertile and can produce hundreds of progeny per week, so it is relatively easy to collect a large number of embryos for high sample numbers. Furthermore, zebrafish undergo rapid development and embryos are transparent, allowing for easy visualization of developmental processes.
This video covers the steps required for the collection of newly fertilized zebrafish embryos. A brief overview of zebrafish mating behavior is presented, followed by instructions for setting up crosses in specialized laboratory breeding tanks that allow for controlled mating. Also covered are the conditions required to initiate the release of eggs (known as spawning) the morning after tanks are set. Next, essential techniques for working with embryos are presented, including the inhibition of pigment development with the chemical PTU, and dechorionation: a procedure in which the shell-like membrane surrounding the embryo (the chorion) is removed. Finally, the video concludes with some practical applications of these techniques in developmental research.
Zebrafish are a small but powerful model system. These prolific fish can generate hundreds of offspring per week and many thousands over their lifetimes. Rapid external development and transparent bodies make the embryos ideal for diverse applications. This video will cover the basics of embryo collection and handling before describing current research methods that take advantage of zebrafish embryos.
In order to generate embryos, it helps to know a little bit about zebrafish mating behav
