Larval developmental parameters at the end of the incubation period in the five treatments (72 h; T1 to T5).

<p>Proportion of embryos that developed to viable D-veliger (±SD; upper left plot), average shell area and length of D-veliger larvae (±SD; upper right and lower left plot, respectively) as well as the amount of calcium incorporated (±SE; lower right plot) are shown. Different letters on bars indicate significant differences in the median values (Kruskal-Wallis and post-hoc Dunn's multiple comparison tests, p<0.05).
