Consumption rates and the nutrition value of tropical algae for Haliotis asinina.

Data show means (±SE) for all indices. Dry weight consumption rates of algae (g 100 g−1 BW day−1) were calculated using wet:dry ratio (cf. Fig 2, fresh weight consumption of algal diets). Dry weight consumption rates of algae bound by carrageenan into artificial diets presented (cf. Fig. 3 fresh weight consumption of artificial diets). Carbon to nitrogen (C:N) ratio, protein content (g 100 g−1 DW: calculated as the sum of amino acids from Table 1), and essential amino acid index are presented. The effective protein content (g 100 g−1 DW: adjusted for the limiting amino acid from Table 1) and the effective protein consumption rate in the algal no-choice feeding assay (Fig. 2) are also presented. Common letter superscripts indicate no significant difference (ANOVA, Tukey’s HSD, p>0.05).
