Fig. 3. Size (total body length, TL) of larvae of P. hypophthalmus as a function of fish age (hours after hatching, hah), fish density and feeding level. Bars and whiskers are the mean and standard errors of 20 fish (two replications per treatment, 10 fish per sample). Bars and whiskers are the means and standard errors of 20 fish for each treatment (10 fish per sample two replicate groups per treatment). Bars with the same shade correspond to treatments with identical prey density (nauplii per volume). Statistics (2-way ANOVA, excluding the 10:81 group): 48 hah: fish density: Pb0.0001, feeding level: Pb0.0001, interaction: P=0.4497; 96 hah: fish density: P=0.0015, feeding level: Pb0.0001, interaction: P=0.3826; 144 hah: fish density: P=0.0027, feeding level: Pb0.0001, interaction: P=0.0018; 192 hah: fish density: P=0.0013, feeding level: Pb0.0001, interaction: P=0.0012. In each graph, bars that share at least one superscript in common do not differ at Pb0.05 (Scheffe F-tests between all 10 treatments).
