Enrichment of rotifers with AA is carried out using ascorbyl palmitate (AP) as a source of
vitamin C to supplement the boosters.
AP is converted by the rotifers into active AA up to 1700 mg.g-1 DW after 24 h enrichment using a 5 % AP (w/w) emulsion (Fig. 3.15.).
The storage of rotifers in seawater after culture or enrichment has no effect on the AA content
during the first 24 h (Fig. 3.15.), indicating that the rotifers maintain their nutritional value
when fed to the larval fish during the culture run.
