摘要: 本试验旨在研究推水养殖模式对宝石鲈肌肉营养品质的影响。选取传统池塘养殖和推水养殖模式下,平均规格500 g左右的宝石鲈各6尾,分别测定其常规营养、肌肉氨基酸及脂肪酸组成。结果显示:推水养殖模式下,宝石鲈肌肉粗蛋白、水分和灰分含量显著升高(P<0.05),粗脂肪含量显著降低(P<0.05)。推水养殖组,除甘氨酸(Gly)含量显著降低(P<0.05)外,其余氨基酸含量与对照组相比无显著差异(P>0.05),其中必需氨基酸占氨基酸总量比为39%~40%,均符合FAO/WHO的理想模式推荐比例(EAA/TAA:40%)。推水养殖组苏氨酸(Thr)、结氨酸(Val)、亮氨酸(Leu)、苯丙氨酸+酪氨酸(Phe+Tyr)和赖氨酸(Lys)的氨基酸指数(AAS)和化学评分(CS)及必需氨基酸指数(EAAI)均显著低于传统池塘养殖组(P<0.05)。推水养殖组饱和脂肪酸总量显著低于传统池塘养殖组(P<0.05)。结果表明,与传统池塘养殖模式相比,推水养殖模式降低了宝石鲈肌肉粗脂肪和饱和脂肪酸含量,提高了粗蛋白含量,在一定程度上提升了宝石鲈品质。

Abstract: This study was conducted to determine the effects of push-water aquaculture mode on the flesh nutritional quality of Scortum barcoo. Six fish with average body weight about 500g under the traditional ponds aquaculture and six under push-water aquaculture modes were selected to determine the muscle routine nutritional components, amino acids and fatty acids composition, respectively. The results showed that the crude protein, moisture and ash contents of fish muscle within push-water aquaculture mode increased significantly (P<0.05), but crude fat content decreased significantly (P<0.05). The glycine (Gly) was significantly decreased within push-water culture mode when compared to that in traditional ponds aquaculture mode, but there is no significant difference in the composition of the remaining amino acids (P>0.05). The ratio of essential amino acids to total amino acid (EAA/TAA) was 39%-40%, which is in line with the recommended ratio of FAO/WHO ideal model (EAA/TAA: 40%). The amino acid index (AAS), chemical score (CS) of threonine (Thr), tyrosine (Val), leucine (Leu), phenylalanine+tyrosine (Phe+Tyr) and lysine (Lys), as well as essential amino acid index (EAAI) within push-water aquaculture group were significant lower than those in the traditional pond aquaculture group (P<0.05). The total amount of saturated fatty acids in the push-water aquaculture group was significantly lower than that in the traditional pond aquaculture group (P<0.05). These findings suggested that compared to traditional pond aquaculture mode, the push-water aquaculture mode could reduce the composition of muscle fat and saturated fatty acid of S. barcoo, but increase the content of crude protein, which improves the muscle quality of S. barcoo.

Key words: Scortum barcoo, push-water aquaculture ecosystem, nutritional components, amino acids, fatty acids
