The objective of the present study was to determine lipid content, fatty acid composition and the recommended daily portion of 13 fish species, nine bivalves, six crustacean, three echinoderm and three cephalopod species, from the Mediterranean Sea (Southern Italy). Fatty acids profile varied significantly among species (p < .05); polyunsaturated fatty acids represented an important proportion, with docosahexaenoic and eicosapentaenoic acids in the highest amount. A high n3/n6 ratio was found in all species (from 1.0 in body wall of Holothuria polii and H. tubulosa to 10.9 in Mytilus galloprovincialis). The lipid nutritional quality indices (atherogenic index, thrombogenicity index and hypocholesterolaemic/hypercholesterolaemic fatty acid ratio) showed crustaceans Parapaeneus longirostris, Plesionika martia, Melicertus kerathurus, Nephrops norvegicus, as likely to be more beneficial for the consumer health. This paper will be of practical value from a health perspective for populations who consume seafood and a powerful marketing tool for farmers.

本研究的目的是确定来自地中海（意大利南部）的13种鱼类，9种双壳类，6种甲壳类，3种棘皮动物和3种头足类动物的脂质含量，脂肪酸组成和建议的每日摄入量。不同物种之间的脂肪酸分布差异很大（p  <.05）；多不饱和脂肪酸占重要比例，二十二碳六烯酸和二十碳五烯酸的含量最高。高N3 / N6比在在体壁的所有物种（从1.0发现玉足polii和H. tubulosa至10.9在紫贻贝）。脂质营养质量指数（动脉粥样硬化指数，血栓形成指数和降胆固醇血症/高胆固醇血症的脂肪酸比率）显示出甲壳类动物Parapaeneus longirostris，Plesionika martia，Melicertus kerathurus，Nephrops norvegicus，这可能对消费者的健康更加有益。从健康的角度来看，本文对于食用海鲜的人群和为农民提供有力的营销工具具有实用价值。
