Figure 5.6 Postembryonic development in the zebrafish (Danio rerio). Numbers indi-
cate standard length in mm, with the period of peak metamorphic remodeling during
the larva-to-juvenile transition indicated by the black box. At standard temperature and
typical rearing densities, this transition begins at about 10-14 days and takes about
2 weeks. As postembryonic fish can develop and grow at markedly different rates, days
of development is an inadequate staging criterion; stages based on morphological
criteria, and their size equivalents have been defined for this species and are preferable
for developmental studies (
Parichy et al., 2009
).
