The fat content and fatty-acid profiles of herring, Clupea harengus membras, from the southern Baltic Sea varied depending on when (fishing season) and where (fishing grounds) the fish were caught as well as on their size and sex. The fat, protein and dry matter content and the fatty-acid profiles were assayed in C. h. membras muscle tissue. The changes observed in fatty-acid profiles were determined by factors such as specimen mass and fat content, which, in turn, depended on fishing season. This is explained by dietary differences between juvenile and older fish. Gonad maturation and spawning in the latter are also factors. The study results provide confirmation of the hypothesis that polyunsaturated fatty acids (PUFA), in particular docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), play vital roles in the sexual maturation of C. h. membras.
鲱鱼（Clupea harengus membras）的脂肪含量和脂肪酸组成因捕捞时间（捕捞季节）、地点（捕捞区）以及个体大小和性别而异。本研究对产自波罗的海南部的鲱鱼肌肉组织的脂肪、蛋白质和干物质含量以及脂肪酸组成进行了检测。脂肪酸组成的变化受样本质量和脂肪含量等因素的影响，而这些因素又取决于捕捞季节。这是因为幼鱼和成年鱼的饮食存在差异，后者的性腺成熟和产卵也是影响因素。本研究结果证实了多不饱和脂肪酸（PUFA），特别是二十二碳六烯酸（DHA）和二十碳五烯酸（EPA），在鲱鱼性成熟过程中发挥重要作用的假设。
