[Zbrafish] Zebrafish Age / Size Variations

[Oliver Braubach]

Dear All.

I have been working on aspects of postembryonic development in the  
zebrafish brain, and have been trying to determine a standard method  
for 'aging' zebrafish. As many of you may be aware, the development of  
individual fish varies greatly during the first month of development,  
which ultimately leads to very noticeable differences in the size of  
individual fish and their organs.

Thus, age does not accurately characterize developmental stages of  
fish, and I have been trying to determine if there's another standard  
method to do so. Has anyone tried to correlate body length to fish  
age? Are there any citations for expected / optimal size of fish are a  
certain age?

Any input regarding this problem would be greatly appreciated.
Best,
