Introduction

Zebrafish or zebra danio (danio rerio) are seen as the latest "model' for embryological development studies. These embryos have the great advantage that they develop as "see through" embryos, that is, all internal development can be clearly observed from the outside in the living embryo. Much of the early work using this embryo model began with Kimmel.[1]

Several large laboratories in the US are now developing large breeding programs to carry out "knockouts" and to find spontaneous mutants of interest.
