| 摘 要： | 随机选取池塘专养(M1)、日本沼虾套养(M2)以及水库放养(M3)三种养殖模式养成的肛长(25.91±3.26)cm的日本鳗鲡作为研究材料, 比较研究了三者间在表皮色差、背肌组织物理特性和肌肉营养成分组成及含量上的差异。结果表明: (1) M1表皮色差与M2、M3均具显著差异(P<0.05), 三者背、腹间的体色差异程度呈M1>M2>M3 (P<0.05); (2) 背肌物性指标中均具显著差异的为粘着性、弹性和回复性, 前者测定值呈M1>M3>M2 (P<0.05), 后两者均呈M3>M1>M2 (P<0.05), M3背肌最发达, M1纵肌肌束纤维排列较M2紊乱; (3) 肌肉营养成分中仅水分和灰分含量均具显著差异, 依次呈M3>M1>M2 (P<0.05)和M3>M2>M1 (P<0.05), 蛋白质含量高于脂肪含量的仅为M3; (4) 三者间肌肉脂肪酸、氨基酸组成均完全相同, 含量排序也均基本一致, 但多种不饱和脂肪酸含量却均具显著差异(P<0.05)。

| Abstract: | Anguilla japonica,/i> in snout-vent lengths of (25.91±3.26)cm were randomly selected as research materials from three cultured populations, namely pond monoculture (M1), pond polyculture (M2) withMacrobrachium nipponense, and reservoir culture (M3). The differences of three populations in epidermal chromatism, physical characteristics of dorsal muscle, and nutritive composition in muscle were studied. The results are as follows: (1) The epidermal chromatism between M1 and M2, M1 and M3 were significantly different (P<0.05). The degree of variance in body color between dorsa and abdomen in M1, M2 and M3 showed an increasing trend (P<0.05). (2) Gumminess, springiness, and resilience were good indicators of physical characteristics of dorsal muscle. The dorsal muscles of M3 was the best, and those of longitudinal muscle of M1 was more irregular than that of M2. (3) The moisture and ash content in muscle were significantly different, in the orders of M3>M1>M2 (P<0.05) and M3>M2>M1 (P<0.05), respectively. Only for M3, the muscle protein content is greater than intramuscular fat content. (4) The composition of fatty acid and amino acid in the three groups were the same, and their orders and contents were consistent in overall. However, differences in the contents of unsaturated fatty acids was notable. |
