Fig. 4. Docosahexaenoic acid (22:6n-3; mol %) in polar lipids as a function of (A) temperature x oyster origin and (B) time x temperature. (C) Eicosapentaenoic acid (20:5n-3; mol %) in the polar lipids as a function of time x temperature x oyster origin. Oysters were collected in the field or produced in the hatchery. Five males and 20 females were mated to produce animals in the pooled group (Pool) whereas F_x represents full-sib families. Data are means (± s.e.m. for B but omitted for clarity in A and C), n=3 aquaria. Different letters indicate significant differences.
