中文摘要:
      鲍的南北接力养殖是我国的一种常见养殖模式,旨在提高南方鲍鱼在夏季的存活率。鲍鱼通常在4月份从中国南方运至北方,11月返回南方。本实验探讨了这种模式对皱纹盘鲍营养成分的影响。测定方法主要依据GB 5009系列。研究样品于2017年12月采样,为相同饵料喂养(龙须菜)的商品鲍。两组鲍分别为全年于南方养殖(连江)的皱纹盘鲍和南北接力养殖的皱纹盘鲍。结果发现,两组鲍足肌中灰分、胶原蛋白、粗脂肪和糖原含量并没有显著差异,但南北接力组(水分:76.50%WW,蛋白质48.40%DW)相比于全年于南方养殖组(水分:73.70%WW,蛋白质:56.80%DW)有较高的水分含量和更低的蛋白质含量。矿物质含量方面,全年于南方养殖的皱纹盘鲍(0.07 mg/100g)足肌中硒的含量高于南北接力养殖组(0.05 mg/100 g)。呈味氨基酸方面,南北接力养殖方式下的皱纹盘鲍,其足肌谷氨酸、牛磺酸、精氨酸、赖氨酸和呈味氨基酸总量显著低于全年南方养殖组。脂肪酸方面,两组鲍有相似的脂肪酸组成,但南北接力养殖组的脂肪酸营养价值较高。研究表明,南北接力养殖模式对皱纹盘鲍的营养成分既有积极影响,又有消极影响,但总体上看差别并不显著。
英文摘要:
      The south-north relay mode of abalone culture, a common practice in China, was designed to increase the survival rate of abalone in the south in summer. The abalone was usually transported to the north(Rongcheng, Shandong) in April from southern China(Lianjiang, Fujian)and returned to the south in November. In this study, the impact of this mode on the nutritive compositions of abalone (Haliotis discus hannai) was investigated. The main method was the series of GB.5009. The determined indexes include moisture, cholesterol, ash, protein, lipid, glycogen, collagen, mineral elements(Mg, Al, Ca, Mn, Fe, Cu, Zn, Se),delicious amino acids(aspartic acid, glutamic acid, glycine, alanine, arginine, methionine, lysine),taurine and fatty acid. SPSS 24.0 statistical software(independent sample t-test)was used to determine the significance of the differences between two groups. The experimental results were expressed as mean ±standard deviation.Two groups of adult abalone(two years old)with the same algae diet (Gracilaria lemaneiformis) were sampled for the analysis in December, 2017. One group was cultured in Lianjiang, Fujian (Southern China) without migration (LJ-DD) and the other was moved to Shandong (Northern China) before the summer and returned to Lianjiang in November (SD-DD). Live samples were moved to laboratory within 24 hours, taking abalone foot muscle to freeze drying after dissection and grinding into powder. These powder were saved in −80 ℃ freezer. The results showed that contents of ash and collagen were higher in LJ-DD, but not significant. The cholesterol, lipid and glycogen content were higher in SD-DD, but not significant. Moisture content was significantly higher in SD-DD (76.50%WW) than in LJ-DD(73.70%WW) while total protein content was significantly lower in SD-DD(48.40%DW). For mineral profile, Se content was significantly higher in LJ-DD(0.07 mg/100g)than SD-DD(0.05 mg/100g). Besides, Mg and Al contents were higher in SD-DD and Ca, Fe, Cu and Zn contents were lower in SD-DD, but the differences were not significant. For amino acid profile, the contents of glutamic acid, arginine, lysine and total delicious amino acid were significantly higher in LJ-DD than in SD-DD. Besides, taurine content was significantly lower in SD-DD than in LJ-DD. For fatty acid profile, C20:3n6 content was significantly higher in LJ-DD than in SD-DD. SFA and N-3 fatty acid were higher in SD-DD,and MUFA, PUFA and EPA+DHA contents were higher in LJ-DD,but not significantly. The value of N6/N3 was lower in SD-DD than in LJ-DD, but the differences were not significant. Overall,two groups had similar composition, but SD-DD had higher nutritional values than LJ-DD. To summarize, the south-north relay mode has both some negative influences and some positive influences on the nutritional quality of H. discus hannai, but such difference is not significant as a whole.
