This paper describes the study of the fatty acid (FA) composition of three fish species (roach, perch, and pike) from Lake Gusinoe (western Transbaikalia). Using principal component analysis, the fatty acid composition of the studied fish species was shown to be species specific. The muscle tissue of roach, perch, and pike was found to contain high levels of polyunsaturated fatty acids (PUFA), including essential docosahexaenoic (DHA), eicosapentaenoic (EPA), and arachidonic acids. Indicators of nutritional quality based on the fatty acid composition showed that the values of the hypocholesterolemic/hypercholesterolemic (HH) ratio indices were sufficiently high. The atherogenicity (AI) and thrombogenicity (TI) indices, which are indicators for the nutritional value, were less than 1 in the studied fish. In terms of flesh lipid quality (FLQ), pike and perch had the highest proportion of total EPA + DHA. According to the obtained data for the composition of fatty acids in the muscle tissue of the studied fish from Lake Gusinoe, the anthropogenic load exerted on Lake Gusinoe has not yet statistically significantly affected the fish muscle quality.
本论文描述了对古西诺湖（外贝加尔西部）三种鱼类（斜齿鳊、鲈鱼和梭鲈）脂肪酸（FA）组成的研究。通过主成分分析，研究表明，所研究鱼类的脂肪酸组成具有物种特异性。结果表明，斜齿鳊、鲈鱼和梭鲈的肌肉组织含有高水平的多不饱和脂肪酸（PUFA），包括必需的二十二碳六烯酸（DHA）、二十碳五烯酸（EPA）和花生四烯酸。基于脂肪酸组成的营养质量指标表明，低胆固醇/高胆固醇（HH）比值指数的值足够高。在研究的鱼类中，致动脉粥样硬化指数（AI）和血栓形成指数（TI）等营养值指标均小于 1。就鱼肉脂质质量（FLQ）而言，梭鲈和鲈鱼的总 EPA+DHA 比例最高。根据古西诺湖三种研究鱼类肌肉组织脂肪酸组成的获得数据，人为负荷对外贝加尔古西诺湖的鱼类肌肉质量尚未产生统计学上显著影响。
