The data revealed a gradient in percentage DHA contents in the PL
fraction of the rotifer larval diets and in Acartia nauplii (stages III–IV)
(Fig. 3), with the lowest value for Brachionus-Low, intermediate value
for Brachionus-High, and highest value for Acartia nauplii (p b 0.05,
see legend). EPA contents in PL showed a similar significant pattern as
DHA, whereas 16:0 and 18:1 fatty acids were found in more equal and variable amounts. The percentage content of ARA in PL was 0.4 and
0.9% of total PL fatty acids in rotifers and Acartia nauplii, respectively
