Developmental experiments
There were no significant differences in the percent change to copepodite between treatments after 24 or 48 h during experiment 3 (Fig. 4a and b). However, a significantly greater percent of Acartia tonsa nauplii developed into copepodites after 72 h of incubation when fed 100% I. galbana and 20:80 Aa:ISO compared to the 80:20 Aa:ISO treatment (ANOVA, P < 0.01; Tukey’s multiple comparison; Fig. 4b).
