Dose–response for UVB exposure during mid-gastrulation in transgenic zebrafish (fli-1) embryos. (A) Percent hatch and mortality of embryos exposed to UVB during the mid-gastrulation stage of development within 5 days of the exposure. (B) Percent malformation of embryos exposed to UVB during the mid-gastrulation stage within 5 days of the exposure. Asterisks indicate a significant difference (P < 0.05) from control treatments without UV irradiation.
