The culture diets, e.g., Chlorella, yeast and rotifer diet from Reed Mariculture, were characterized by relatively high levels of protein (37–51% DM) and relatively low levels of lipid (1.5–13% DM) accompanied by a high phospholipid to neutral lipid (PL:NL) ratio, PL amounting to 38–44% of total lipids ( Table 2, data not given for yeast). Yeast was devoid of long chain fatty acids, Chlorella contained EPA and DHA at 4 and 9% of total fatty acids (TFA), while rotifer diet contained relatively high levels of ARA and EPA (3.4 and 24% of TFA, respectively) and insignificant levels of DHA. The enrichment diets, ORI-GREEN, Larviva Multigain and Red Pepper, contained 41–43% lipid, where 84–96% was NL. The fatty acid composition was characterized by relatively low levels of ARA and EPA, but high levels of DHA (24–34% of TFA). ORI-GREEN had a relatively high level of protein (43% of DM), while Multigain and Red Pepper contained 12 and 17% protein of DM, respectively. The enrichment diet of hatchery A and the S. Presso diet used in one of the enrichments from hatchery D were not analyzed. PL and protein were added in the enrichment diet from hatchery A, but the precise levels are not known
