There is an error on page 7.12 of the Zebrafish Book (3rd Edition, 1995). The protocol for Production of Haploid Embryos, step 3, should read:
"3. Irradiate sperm with an ultraviolet light (UV, e.g. 38 cm from a 43 cm long Sylvania germicidal tube) for 2 min."
The distance is incorrectly stated as "29 cm".
note: It is listed correctly on page 7.7 as 38 cm or 15 inches.
Please make this correction on your copy and advise others who may be using this protocol.
Sorry for the inconvenience.
