| 摘 要： | 为了了解循环水养殖系统养殖条件下鱼类肌肉的营养成分,开展鱼类品质调控研究。本研究通过比较循环水养殖系统养殖条件下与池塘拟野生条件下俄罗斯鲟肌肉的常规营养成分、氨基酸和脂肪酸组成,并进行对比评价。结果表明,两种条件下俄罗斯鲟肌肉中一般营养成分不存在显著差异,均检出17种氨基酸,氨酸酸各组成成分含量方面两者无显著差异。氨基酸评分(AAS)和化学评分(CS)结果显示：循环水系统养殖条件下第一限制性氨基酸均为蛋-胱氨酸,赖氨酸在必需氨基酸中评分最高,必需氨酸基指数EAAI循环水组高于池塘组。循环水组检出20种脂肪酸,池塘组检出14种脂肪酸,两者脂肪酸总量无明显差异,脂肪酸各组成成份有较大差异,其中二十二碳六烯酸(DHA)循环水组显著高于池塘组。综上所述,循环水养殖系统养殖条件下俄罗斯鲟肌肉的营养价值不低于池塘拟野生条件下的俄罗斯鲟。

Muscle Nutrient Composition of Russian Sturgeon (Acipenser gueldenstaedtii) Under Different Culture Modes: Comparison and Analysis |
| |
| Abstract: | To understand the nutrient composition of fish muscle under the condition of recirculating aquaculture system, and to study the quality control of fish, in this study, the nutrient composition, amino acid and fatty acid composition of Russian sturgeon (Acipenser gueldenstaedtii) muscle were compared in recirculating aquaculture system and in ponds under simulated wild conditions. The results showed that there was no significant difference in the general nutrient composition between the two conditions. 17 kinds of amino acids were detected, and there was no significant difference in the content of each component of amino acid between the two conditions. Amino acid score (AAS) and chemical score (CS) showed that the first restrictive amino acid in recirculating aquaculture system was methionine, the lysine scored the highest among essential amino acids, and essential amino acid index (EAAI) in recirculating aquaculture system was higher than that in pond aquaculture system. The circulating water group detected 20 kinds of fatty acids and the pond group detected 14 kinds of fatty acids, there was no significant difference in the total amount of fatty acids between the two groups. There were significant differences in the composition of fatty acids. Among them, DHA was significantly higher in the circulating water group than in the pond group. In conclusion, the nutritive value of the muscle of Russian sturgeon under the recirculating aquaculture system is no less than that under the simulated wild condition pond. |
