zebrafish sex differentiation

[hornung at STUDENTS.WISC.EDU]

Does anyone out there know when sexual differentiation occurs in zebrafish?
I am interested in pursuing research at this stage of development and have
found information from many other species but it seems to be absent in the
zebrafish literature.  It would seem from the data I have
found in other species that it may occur shortly after they begin
feeding.

thanks
