A comparative study of the lipid status (i.e., the total lipid and phospholipid concentrations and the percentage of fatty acids of the total lipids) of adult specimens of daubed shanny (Leptoclinus maculatus) from Svalbard waters (Isfjord) and slender eel blenny (Lumpenus fabricii) from the White Sea (Onega Bay and Tersky shore) was performed to study the metabolism and functions of lipids of these fishes in ontogeny and under various ecological conditions. Slender eel blenny from both areas of the White Sea were distinguished by a high level of sphingomyelin compared with the daubed shanny from Svalbard, and the amount of total phospholipids was higher in slender eel blenny from Onega Bay than in slender eel blenny from the Tersky shore. The extent of saturation and the signature of polyenic fatty acids varied according to the specific species of the Stichaeidae family under study. These results demonstrate the differences in the trophoecological and hydrobiological conditions of habitations of these species and highlighted the importance of considering certain trends in the lipid profiles of these fishes as specific features of the organization of the ecological and biochemical mechanisms of adaptation.
对来自斯瓦尔巴德群岛水域(伊斯峡湾)的斑纹沙鳗(Leptoclinus maculatus)成年标本和来自白海(奥涅加湾和特尔什基海岸)的细长鳗鳚(Lumpenus fabricii)的脂质状况(即总脂质和磷脂浓度以及总脂质中脂肪酸的百分比)进行了比较研究,以探讨这些鱼类在个体发育过程中以及在各种生态条件下脂质的代谢和功能。与来自斯瓦尔巴德群岛的斑纹沙鳗相比,来自白海两个区域的细长鳗鳚的鞘磷脂水平较高,并且奥涅加湾的细长鳗鳚的总磷脂含量高于特尔什基海岸的细长鳗鳚。所研究的绒杜父鱼科特定物种的饱和程度和多烯脂肪酸特征各不相同。这些结果表明了这些物种栖息地的营养生态和水生物学条件存在差异,并强调了将这些鱼类脂质谱中的某些趋势视为生态和生化适应机制组织的特定特征的重要性。
