Abstract：
In the study, the physical characteristics, nutritional composition, mineral elements, volatile substances, and serum biochemistry of common carp (Cyprinus carpio) after rearing for two months were compared and analyzed to reveal the differences in muscle nutritional quality and serum biochemical indices between fish raised in traditional ponds (TP) and land-based container recirculating aquaculture systems (C-RAS). One hundred fish were selected from each aquaculture mode for the following experiments. Results show that: in terms of physical properties, C-RAS frozen seepage rate was significantly lower than that in TP (P < 0.05), the chewiness, gumminess, springiness, resilience, adhesiveness, cohesiveness, and shearing of C-RAS group were significantly higher than in TP (P < 0.01). Regarding muscle nutrients, the moisture, the crude lipid contents of C-RAS group were significantly lower than that of the TP group (P < 0.05), and the crude protein content of C-RAS group was extremely significantly higher than that in TP (P < 0.01). The saturated fatty acids (ΣSFA) and polyunsaturated fatty acids (ΣPUFA) in the muscle of C-RAS were significantly higher than that in TP (P < 0.01), and monounsaturated fatty acids (ΣMUFA) of C-RAS were significantly lower than that in TP (P < 0.01). Methionine content in C-RAS was significantly higher than that in TP (P < 0.05). In terms of mineral elements, the contents of K and Se in C-RAS were significantly higher than those in TP, and the content of Zn in C-RAS was significantly lower than that in TP (P < 0.05). In terms of volatile substances, nonanal, octanal, and benzaldehyde in C-RAS were significantly lower than those in TP(P < 0.01), 2,3-diethyl-5-methylpyrazine, ethyl 3-methylpentanoate, butyl formate were significantly higher than those in TP (P < 0.01). In terms of serum biochemistry, the glucose index in C-RAS was extremely significantly lower than that in TP group, total protein, albumin, alkaline phosphatase, and triglyceride were extremely significantly higher than those in TP (P < 0.01). Experiments show that the aquaculture mode has a large impact on the physical properties of the common carp, nutrients, mineral elements, volatile matter, and serum biochemical. In conclusion, the common carp cultured in C-RAS systems had better muscle nutritional quality, which provides a reference for future regulation of fish nutritional quality by C-RAS.
摘要：
在研究中,物理特征，营养成分,矿物元素,挥发性物质,对养殖2个月后的鲤鱼(Cyprinuscarpio)和血清生化指标进行了比较分析，揭示了传统池塘养殖(TP)和陆基容器循环养殖系统(C-RAS)养殖鱼类肌肉营养品质和血清生化指标的差异。从每种水产养殖模式中选择一百条鱼进行以下实验。结果表明:在物理性质方面,C-RAS冻结渗流率明显低于TP(P<0.05),耐嚼，发胶,弹性，弹性，粘附性,凝聚力,C-RAS组的剪切明显高于TP组（P<0.01）。关于肌肉营养素，水分，C-RAS组脂肪含量显著低于TP组(P<0.05),C-RAS组的粗蛋白含量极显著高于TP组(P<0.01)。C-RAS肌肉中的饱和脂肪酸（ΣSFA）和多不饱和脂肪酸（ΣPUFA）明显高于TP（P<0.01）。C-RAS的单不饱和脂肪酸（ΣMUFA）显着低于TP（P<0.01）。C-RAS中蛋氨酸含量显著高于TP(P<0.05)。就矿物元素而言,C-RAS中的K和Se含量显著高于TP,C-RAS中的Zn含量明显低于TP（P<0.05）。在挥发性物质方面，非肛门，octanal,C-RAS中的苯甲醛明显低于TP（P<0.01），2,3-二乙基-5-甲基吡嗪,3-甲基戊酸乙酯,甲酸丁酯显著高于TP(P<0.01)。在血清生物化学方面，C-RAS组血糖指数极显著低于TP组,总蛋白质，白蛋白,碱性磷酸酶,甘油三酯极显著高于TP(P<0.01)。实验表明,养殖模式对鲤鱼的物理性质有较大的影响,营养素,矿物元素,挥发性物质，和血清生化.总之,在C-RAS系统中培养的鲤鱼具有更好的肌肉营养品质，为今后利用C-RAS调控鱼类营养品质提供参考。
