Abstract:
The total fat content (% (w/w)) of eight-month-old farm-raised sandworms (21.0%), Perinereis nuntia which were in the beginning stage of reproductive cell synthesis, was slightly (1.2-fold) higher than those aged 2, 4 and 6 months (17.4%) and ~1.5-fold higher than that found in wild-caught sandworms (13.4%). The ratio of saturated: monounsaturated: polyunsaturated fatty acid (SFA: MUFA: PUFA) in farm-raised worms were ~1.3:1:1, while for wild-caught sandworms these ratios were significantly different at 4:2.2:1 and 2.3:1.5:1 for summer and winter season caught sandworms, respectively. The ratio of arachidonic acid: eicosapentaenoic acid: docosahexaenoic acid (ARA: EPA: DHA) of farm-raised P. nuntia of 4, 6 and 8 months age were all similar, at ~1.6:1.3:1, but significantly varied between summer (1.7:1:0) and winter (0.9:1:0.4) wild-caught sandworms. The ratio of n-3: n-6 fatty acids in farm-raised sandworms did not significantly differ between age groups (1:3) or summer wild-caught sandworms (1:3.2) but was much higher in winter season wild-caught sand worms (1:1.7). The different fatty acid profiles between farm-raised and wild-caught sandworms may arise from their respective diets and habitats. The major lipid component was phospholipids, especially Phosphatidylcholine (PC). The most abundant constituent of PC in farm-raised and wild-caught sandworms was PC C16:0/C18:1, but the second and third most abundant PC differed, being PC C16:0/C18:2 and PC C18:0/C18:2 in farm-reared sand worms and PC C16:0/C20:4 and PC C18:0/C20:4 in wild-caught ones. The cholesterol level in wild-caught sandworms (493 mg/100 g dw) was 1.5-fold higher than that of farm-raised sandworms (323 mg/100 g dw).
