To determine temperature effects on hatching success of white bass (Morone chrysops) embryos, sample lots of fertilized eggs were exposed to 10 constant temperatures, 6 through 30C. Exposures were begun at two stages of embryonic development, before gastrulation and after closure of the blastopore. Embryos exposed before gastrulation were more sensitive to extreme temperatures than those exposed after closure of the blastopore. The percentage of normal larvae hatched from embryos exposed before gastrulation was not significantly impaired over the temperature range 18 - 26C (P>0.05). When first exposed after blastopore closure the range of temperatures allowing unimpaired hatching was extended to 14 - 26C (P>0.05). Normal larvae hatched at 14 - 28C from embryos exposed before gastrulation and at 10 - 28C when exposed after blastopore closure, but at the extremes in significantly reduced numbers (P<0.05). Hatching took place 4.5 days after fertilization when incubation at 14C and 1 day after fertilization at 26C. The 24-hr TL50 for white bass larvae exposed within 24 hr of hatching and acclimated at temperatures from 14 to 26C was between 30 and 32C and was not altered by acclimation.
