对野生及人工养殖瓦氏黄颡鱼的肌肉营养成分和营养品质进行了分析比较。结果表明,野生瓦氏黄颡鱼肌肉中水分显著高于人工养殖瓦氏黄颡鱼(P<0.05),而粗脂肪含量显著低于人工养殖瓦氏黄颡鱼(P<0.05),粗蛋白和粗灰分含量两者无显著差异(P>0.05)。野生和人工养殖瓦氏黄颡鱼氨基酸组成基本一致,均含有17种以上氨基酸(色氨酸含量较低未测定)。除酪氨酸外,其余各项氨基酸指标均无显著差异(P>0.05)。氨基酸平衡性分析结果表明,瓦氏黄颡鱼氨基酸组成符合FAO/WHO标准,具有较好的平衡性,蛋白品质较好。野生瓦氏黄颡鱼较养殖瓦氏黄颡鱼ω3脂肪酸高。瓦氏黄颡鱼肌肉贮存脂肪高,是一种较优的经济鱼类。
Nutritional qualities and muscle nutrients of wild and cultivated Valvoline were analyzed and compared. The results showed that the water content in the muscle of the wild Wahfish was significantly higher than that of the cultivated Wahfish (P <0.05), but the content of crude fat was significantly lower than that of the cultivated Wahfish (P <0.05) And crude ash content both had no significant difference (P> 0.05). The amino acid composition of wild and cultivated Valsalva catfish was basically the same, all containing more than 17 kinds of amino acids (the content of tryptophan was not determined). In addition to tyrosine, the remaining amino acid indicators were not significantly different (P> 0.05). Amino acid balance analysis showed that the amino acid composition of the fish was consistent with FAO / WHO standards, has a good balance of protein quality is better. Wild Valsalva catfish more cultured Waga yellow catfish omega 3 fatty acids high. Valsalla catfish muscle fat storage is a better economic fish.
