Table 2. Percentage (%) of individual fatty acids to total FA concentration of cultures in which: (i) O. marina was depleted of prey at the start of the experiments (Day 0 Om); (ii) the E. huxleyi cultures fed to O. marina; (iii) after three days fed non-infected E. huxleyi (Om + Eh non-inf); and (iv) after 3 days fed infected E. huxleyi (Om +Eh inf).
Values are mean ± one standard deviation, n = 4, n = 4, n = 3 and n = 3, respectively. Note the values for E. huxleyi are the average of duplicate non-infected and duplicate infected cultures.
