Fig. 2. Experiment 1. Wet weight of Loxechinus albus juveniles fed with different natural
foods for 90 days. The values represent the mean of 9 replicates (standard error
bars have been omitted to simplify the figure). Vertical bars at the right of the graph
overlap treatments that did not differ significantly (P N 0.05, Tukey's test) at the end of
the 90-day experiment.
