Representation of a typical Hertwig effect curve in the sea bass. Survival of fertilized eggs at two different times during early ontogenesis: embryogenesis (48 HPF) and hatching (72 HPF) is shown as a function of the dose of UV-irradiation applied to different aliquots of the sperm used for fertilization. The sperm was diluted 1 : 10 prior to irradiation. Each data point is the mean plusminus SEM of two separate experiments with triplicate determinations for each dose. The dotted line indicates expected survival at 48 HPF when extrapolated from lower ( less than or equal to 25 000 erg mm^–2) to higher ( greater than or equal to 35 000 erg mm^–2) doses of UV light. Differences between expected and observed survival with doses 35 000 erg mm^–2 evidence a typical Hertwig effect.
