Abstract
A fatty acid content of structural (phospholipids, PLs) and storage (triacylglycerols, TAGs) lipids in muscles of daubed shanny Leptoclinus maculatus postlarvae from Kongsfjord (Svalbard archipelago waters) was studied. A high level of monounsaturated fatty acids (MUFAs), mainly due to 20:1(n-9) and 22:1(n-11), was shown in TAGs of daubed shanny muscles at the L2 stage of larval development. Polyunsaturated fatty acids (PUFAs) were found to dominate in PLs due to n-3, mainly 20:5(n-3) and 22:6(n-3), fatty acids. The ∑n-3/∑n-6 PUFA index was established to be 2-fold higher in PLs compared to TAGs (9.7 vs. 4.1). The fatty acid profile at the L1 stage of larval development was characterized by a pronounced specificity: a highest content of saturated fatty acids (SFA) due to 16:0 and a dominance of 18:1(n-9) among MUFAs. Our results demonstrate the age-related specificity of the fatty acid content of PLs and TAGs in daubed shanny muscles, which determines their functional significance and reflects both feeding features and the physiological state of the daubed shanny at different stages of its development under the Arctic conditions.
