Table 3
Fatty acid composition (mass % of total FA, mean ± S.D.) of the neutral lipids of Holothuria scabra fed the different treatments at the beginning of the experiment (T0) (n = 5), after 3 months (n = 3 for each treatment) and after 7 months (n = 9 for each treatment).Different letters indicate significant differences (KW tests followed by Conover-Iman multiple comparison tests with Bonferroni's adjustment method, at significant level α< 0.05), indicating variations of FA compositions between treatment at 3 months and 7 months. SFA: saturated FA; MUFA: monounsaturated FA; PUFA: polyunsaturated FA; Branched: FA [15iso+15anteiso+16iso+17iso+17anteiso].
