Table 5.

Proximate (lipid, ash, and protein content (%dry matter)) and fatty acid composition (%TFA) of P. vannamei postlarvae 1 (PL1) and 12 (PL12) fed enriched Artemia with different experimental emulsions and unenriched Artemia. Lipid contents and FA data represent means ± SD (n = 3). Different superscripts within each row indicate a significant difference between diets (ANOVA (P ≤ 0.05), Tukey's HSD).
