本研究的目的是调查不同种类的深水和浅水对虾的脂肪酸组成。调查的对虾种类有：深水对虾、叶对虾、对虾、长吻对虾和对虾；浅水对虾、半硫化对虾、角对虾和日本对虾。对虾的脂肪酸组成各不相同。主要脂肪酸为C18：1n9、C16：0、C25：6n3、C22：5n3和C18：0。长吻对虾、华东对虾和斑节对虾的饱和脂肪酸、单不饱和脂肪酸和多不饱和脂肪酸(PUFA)含量存在显著差异。单角藻可食组织的n6/n3比值为0.795，而叶黄连的n6/n3为0.152。在所研究的物种中，角叉尾轮虫的二十二碳六烯酸+二十碳五烯酸值最高。浅水虾的多不饱和脂肪酸含量(33.44%~42.77%)高于深水虾(29.68%~33.95%)。上层水层的海洋动物通过浮游植物获取营养，浮游植物依靠太阳能提供n-3PUFA。浅水对虾品种提供了令人满意的多不饱和脂肪酸。
The aim of this study was to investigate fatty acid profiles of different shrimp species caught from deep water and shallow water. The shrimp species investigated in the study were Aristeus antennatus, Aristeomorpha foliacea, Plesionica martia, Parapenaeus longirostris, and Plesionica edwardsi from deep water; and Metapenaeus monoceros, Penaeus semisulcatus, Penaeus kerathurus, and Penaeus japonicus from shallow water. Fatty acid composition of shrimps varied. The main fatty acids were C18:1n9, C16:0, C25:6n3, C22:5n3, and C18:0. Saturated, monounsaturated, and polyunsaturated fatty acid (PUFA) contents of P. longirostris, P. edwardsi, and M. monoceros were markedly different, respectively. The ratio of n6/n3 of the edible tissue of M. monoceros was found to be 0.795, whereas this value was 0.152 in A. foliacea. Among the species studied, the highest docosahexaenoic acid + eicosapentaenoic acid value was found for P. kerathurus. The levels of PUFAs of shallow water shrimps (ranging from 33.44 to 42.77%) were found to be higher than those of deep water shrimps (ranging from 29.68 to 33.95%). Marine animals in the upper water layers gain nutrition through phytoplankton which provides n-3 PUFA depending on solar energy. Shallow water shrimp species provide a satisfying amount of PUFA.
