中文摘要:
      为了探究人工养殖条件下宽体沙鳅(Sinibotia reevesae)亲鱼的肌肉营养组成,为其营养学研究提供基础资料。采用常规分析的方法,测定了30尾人工养殖宽体沙鳅亲鱼的肌肉营养成分,并对其营养价值进行了综合评价。结果表明,人工养殖宽体沙鳅亲鱼肌肉中的水分、粗蛋白质、粗脂肪和灰分的含量分别为(75.24±2.25)%、(19.32±0.33)%、(6.60±0.59)%、(1.15±0.01)%;肌肉中共检测出18种氨基酸,氨基酸总量占肌肉干重的(76.42±0.62)%,必需氨基酸总量/氨基酸总量(WEAA/WTAA)为39.96%,必需氨基酸总量/非必需氨基酸总量(WEAA/WNEAA)为66.55%。氨基酸中以鲜味特征氨基酸谷氨酸和天门冬氨酸含量最高。8种必需氨基酸中,赖氨酸含量最高,为4.54 mg/g,必需氨基酸指数为63.94。共测得脂肪酸20种,多不饱和脂肪酸含量为(20.99±0.02)%,EPA和DHA总含量为(3.54±0.04)%。人工养殖宽体沙鳅亲鱼营养丰富均衡,具有较高的食用价值。
英文摘要:
      Sinibotia reevesae is a fish endemic only to the upper Yangtze River. The nutritional quality of adult cultured S. reevesae was evaluated by analyzing the muscle tissue of thirty individuals of average body length, (92.27±7.70) mm, and body weight, (12.56±3.59) g. The results provide a reference for nutritional content and for protecting and culturing S. reevesae. The muscle of cultured S. reevesae was composed of water (75.24±2.25%), protein (19.32±0.33%) and fat (6.60±0.59%). The protein includes 18 amino acids and accounting for (76.42±0.62%) of the muscle dry weight, higher than the standard set by the Food and Agriculture Organization (FAO). The weight ratio of essential amino acids to total amino acids (WEAA/WTAA) was 39.96% and the ratio of essential to nonessential amino acids (WEAA/WNEAA) was 66.55%. The concentrations of aspartic acid (Asp) and glutamic acid (Glu), the “delicious amino acids”, were highest and the essential amino acids index (EAAI) was 63.94. Twenty different fatty acids were found in the muscle, including 7 saturated fatty acids (SFA), 6 monounsaturated fatty acids (MUFA) and 7 polyunsaturated fatty acids (PUFA). Among the unsaturated fatty acids (UFA), the concentration of C18:1ω9c was highest. The concentration of PUFAs were low, with EPA and DHA together accounting for (3.54±0.04%) of the dry weight. To summarize, the muscle of cultured S. reevesae parent fish is a delicious, high quality protein food with high nutritional value. However, it is necessary to scientifically manage the EPA and DHA content of feed during artificial breeding to ensure normal reproduction of S. reevesae and the healthy development of offspring.
