Why zebrafish research?

The zebrafish is a commonly used model organism in the biological sciences, similar to the mouse or rat. Zebrafish can grow to 4-5 cm and are easily handled in aquatic systems. Since their discovery for use in research in Prague in the 1980’s, this fish has been established in many laboratories worldwide. The generation time of the zebrafish, from embryo to a breeding adult fish, is very short. Due to their transparent nature, developing Zebrafish embryos are very well suited for imaging purposes. There are very strict rules you have to follow if you want to work with laboratorial animals.
