Fig. 3 Paternal starvation significantly enhances larval growth but delays hatching. (a) F1 survival at 24 hpf (Left): The analysis of several embryo clutches revealed no statistically significant changes in survival between embryos from fed and starved fathers. Individual data points within the violin plot represent the average egg survival rate per male and across 7 independent tanks. F1 survival at 2 months post fertilization (Right). No significant differences were found at this stage. Individual data points within the violin plots represent average offspring survival (b). Larvae length: Larval growth was measured at 5 and 8 dpf in larvae from several clutches. Individual data points in the violin plot represent the average of larvae length per tank. (c) Hatching rates: The percentage of hatched embryos was analysed every 2 h between 48 and 58 hpf. (d) F1 abnormal eggs as determined at 64-cell stage (2 hpf). Eggs from males and females from fed and starved fathers were collected and analysed upon natural mating. No statistical differences were observed in the egg quality between groups or between groups and either sex.
