Greenshell™ mussels (GSM-Perna canaliculus) are a source of omega-3 (n-3) long-chain polyunsaturated fatty acids (LC-PUFA). Farmed GSM are considered to be a sustainable source of LC-PUFA as they require no dietary inputs, gaining all of their oil by filter-feeding microorganisms from sea water. GSM oil is a high-value product, with a value as much as 1000 times that of fish oils. GSM oil has important health benefits, for example, anti-inflammatory activity. It also contains several minor lipid components that are not present in most fish oil products, and that have their own beneficial effects on human health. We have shown the lipid content of the female GSM (1.9 g/100 g ww) was significantly greater than that of the male (1.4 g/100 g ww). Compared with male GSM, female GSM contained more n-3 LC-PUFA, and stored a greater proportion of total lipid in the gonad and mantle. The higher lipid content in the female than the male GSM is most likely related to gamete production. This information will be useful to optimize extraction of oils from GSM, a local and sustainable source of n-3 LC-PUFA.
绿贻贝（Perna canaliculus）是ω-3（n-3）长链多不饱和脂肪酸（LC-PUFA）的来源。养殖绿贻贝被认为是 LC-PUFA 的可持续来源，因为它们不需要饮食投入，而是通过滤食海水中的微生物来获得所有的油。绿贻贝油是一种高价值的产品，其价值是鱼油的 1000 倍。绿贻贝油具有重要的健康益处，例如抗炎活性。它还含有几种在大多数鱼油产品中不存在的少量脂质成分，这些成分对人类健康有自己的有益影响。我们已经表明，雌性绿贻贝（1.9 g/100 g ww）的脂质含量明显高于雄性（1.4 g/100 g ww）。与雄性绿贻贝相比，雌性绿贻贝含有更多的 n-3 LC-PUFA，并将更大比例的总脂质储存在性腺和套膜中。与雄性绿贻贝相比，雌性绿贻贝的脂质含量更高，这很可能与配子的产生有关。这些信息将有助于优化从绿贻贝中提取油，这是一种本地和可持续的 n-3 LC-PUFA 来源。
