Check out a paper in ScienceDirect available online at www.sciencedirect.com Entitled: High-throughput zebrafish histology by Sabaliauskas et. Al.

Good Luck!

Have you checked out the histological methods section of "The Zebrafish Book" by Monte Westerfield, on zfin.org available online here: http://zfin.org/zf_info/zfbook/cont.html#cont8
I don't think it has paraffin embedding protocols but perhaps there are some other hints will help? In any case, it's an amazing resource.

I am also wondering if it might help to embed in agarose before paraffin embedding - especially those 44 hour old critters who are tiny tiny tiny. Unfortunately most of my experience in that regard lies with frozen sectioning so I don't have too much to add.
