Abstract

The n-3 polyenoic fatty acids (phytoplankton origin) dominate in the fatty acid composition of seston, which is a food source for bivalves; this indicates the predominance of diatoms in the seston composition. The distribution of the main classes of lipids and their fatty acids in the tissues of blue mussels depends on the mollusk body size. As the body size of the mollusk increases, the ratio of membrane lipids decreases, and high-energy saturated and monounsaturated fatty acids accumulate in storage lipids. The bulk of the n-3 polyenoic acids consumed by mollusks in seston (i.e., their food) accumulates in the tissues of mollusks and is used for their metabolism, whereas the long-chain saturated fatty acids, oleic acid and the n-6 polyenoic acids, are excreted with faecal pellets.

蓝贻贝Mytilus edulis L.的脂肪酸，硒，组织和粪便颗粒中的脂肪酸分布。

摘要

n-3多烯脂肪酸（浮游植物来源）在双壳类动物的食物来源——seston的脂肪酸组成中占主导地位。这表明硅藻在活塞组成中占主导地位。蓝贻贝组织中主要类别的脂质及其脂肪酸的分布取决于软体动物的体型。随着软体动物的体型增加，膜脂质的比率降低，并且高能饱和和单不饱和脂肪酸积累在储存脂质中。软体动物在食肉中消耗的大部分n-3聚烯酸（即它们的食物）积聚在软体动物的组织中并用于其代谢，而长链饱和脂肪酸，油酸和n-6聚烯酸酸与粪便颗粒一起排出体外。
