Total lipids and fatty acids composition of the coastal and the deep-sea common octopus (Octopus vulgaris) populations: a comparative study.
Nutr Health. 2008; 19(3):195-201.NH

Abstract

The aim of this work was to investigate biochemical differences between Octopus vulgaris caught off costal zone and from the deep-sea of the Golf of Gabès (South coast of Tunisia). In both fishing grounds, octopus total lipids constituted almost 1.5% of wet tissue showing no significant difference (p < 0.05). The percentage distribution of fatty acids was not significantly different, neither between males and females, nor between both areas. Polyunsaturated fatty acids constituted about 50 % of the total fatty acids. Docosahexaenoic (DHA; C22:6 omega 3), eicosapentaenoic (EPA; C20:5 omega 3) and the arachidonic acids (C20:4) were the most important of this group with percentages of 25, 14 and 10% respectively. The saturated fraction constituted almost 30% of the total fatty acids. The most dominant saturated fatty acids were palmitic acid (C16:0) and stearic acid (C18:0), with 18% and 7% respectively. The monounsaturated content was found to contribute only 10% of the total fatty acids. Most of the monounsaturated fat was present as oleic acid (C18:1) and palmitoleic acid (C16:1) with 2.5% and 1.5% respectively. The presence of arachidonic acid in substantial proportions with an omega 3 to omega 6 ratios of 3.9 to 1 is of special interest because of the role of cephalopods in the traditional Mediterranean diet.
