Mollusks are excellent dietary sources for LC-PUFA. However, the main challenge limiting mollusk production is the high mortality rate of molluskan larvae in early life cycle stages. This paper reviews scientific evidences on molecular and biochemical studies of LC-PUFA biosynthesis in commercially important molluskan species. It carefully summarizes the pertinent data published on specific research questions to improve the understanding of the diverse evidences. It is helpful to clarify the current state of research and determine topics for future studies on LC-PUFA biosynthesis in mollusks. From the analysis of published data, mollusks have the ability to biosynthesis LC-PUFA to a certain extent. LC-PUFA biosynthesis information of commercially important molluskan species can be useful to determine the fatty acids essential for their diet. Therefore, specific management strategies or feeds can be developed to strengthen the industry by improving the health and survival rate of molluskan larvae.
贝类是长链多不饱和脂肪酸（LC-PUFA）的极佳膳食来源。然而，限制贝类生产的主要挑战是贝类幼虫在早期生活史阶段的高死亡率。本文综述了关于商业上重要贝类物种 LC-PUFA 生物合成的分子和生化研究的科学证据。它仔细总结了关于特定研究问题的相关数据，以提高对不同证据的理解。这有助于阐明当前的研究状况，并确定贝类中 LC-PUFA 生物合成未来研究的主题。从已发表数据的分析来看，贝类在一定程度上具有合成 LC-PUFA 的能力。商业上重要的贝类物种的 LC-PUFA 生物合成信息可用于确定其饮食中必需的脂肪酸。因此，可以制定特定的管理策略或饲料，通过提高贝类幼虫的健康和存活率来加强该行业。
