Results are presented as (). CD: control diet; CD + MU7: control diet supplemented with 7% multispecific macroalgal wrack; CD + MO7: control diet supplemented with 7% monospecific macroalgal wrack; FA: fatty acid; SFA: saturated fatty acids; MUFA: monounsaturated fatty acids; PUFA: polyunsaturated fatty acids; LC-PUFA: long-chain polyunsaturated fatty acids (≥C20 and ≥2 double bonds). Totals include other minor components not shown. 1Mainly n-7 isomer; 2mainly n-9 isomer. Different letters in superscript denote significant differences among dietary treatments ().
