| 摘要: |
| 为探究盐碱水养殖对大黄鱼肌肉营养的影响，本试验将大黄鱼鱼苗置于盐碱水和自然海水 两种不同水体中进行养殖，比较分析了大黄鱼成活率、生长性能和肌肉营养成分。结果显示，养殖 40 d 后， 自然海水养殖组的大黄鱼成活率和生长速度均显著高于盐碱水养殖组（P ＜ 0.05）。盐碱水养殖组的大黄鱼肌肉中粗蛋白质含量为（13.6±0.21） ％，显著高于自然海水养殖组（P ＜ 0.05，以鲜重计，下同）；氨基酸总量、必需氨基酸和鲜味氨基酸含量均高于自然海水养殖组，但差异不显著（P ＞ 0.05）；氨基酸指数 EAAI 达 79.3，高于自然海水养殖组。盐碱水养殖组大黄鱼肌肉的多不饱和脂肪酸、高度不饱和脂肪酸、EPA+DHA 含量（13.6±1.6）％均显著高于自然海水养殖组（P ＜ 0.05）；其中，n-3PUFA 的含量显著高于自然海水养殖组（P ＜ 0.05）， n-6PUFA 的含量（12.4±1.0）％虽然低于自然海水养殖组，但差异不显著（P ＞ 0.05）。不同水体养殖的大黄鱼肌肉中总汞含量在（0.013 4±0.007 2） ～（0.016 3±0.010 7）mg/kg 之间，甲基汞、无机砷和总砷均未检出。结果表明，在盐碱水中养殖大黄鱼具备一定的推广潜力。 |

| Abstract: |
| To investigate the influence of saline-alkali water aquaculture on the muscle nutrition of Larimichthys crocea，this experiment reared the fry of Larimichthys crocea in two distinct water bodies：saline-alkali water and natural seawater and conducted a comparative analysis of the survival rate，growth performance，and muscle nutrition composition of Larimichthys crocea．The results demonstrated that after 40 days rearing，the survival rate and growth rate of Larimichthys crocea in natural seawater group were significantly higher than those in the saline- alkali water rearing group（P ＜ 0.05）．The content of crude protein in the muscle of Larimichthys crocea reared in saline- alkali water was（13.6±0.21）％，which was significantly higher than that in the natural seawater rearing group（P ＜ 0.05，based on fresh weight，the same applies below）．The total amino acid content，essential amino acids， and umami amino acid content in the saline-alkali water rearing group were all higher than in the natural seawater rearing group，but the differences were not significant（P ＞ 0.05）．The amino acid index（EAAI）reached 79.3，which was higher than that in the natural seawater rearing group．The muscle of Larimichthys crocea reared in the saline-alkali water showed significantly higher levels of polyunsaturated fatty acids（PUFA），highly unsaturated fatty acids，and EPA+DHA content（13.6±1.6）％ compared with the natural seawater-raised group（P ＜ 0.05）．Among these， the content of n-3PUFA cotent was significantly higher than that in the natural seawater rearing group（P ＜ 0.05）； although the n-6PUFA content（12.4±1.0）％ was lower than that in the natural seawater culture group，the difference was not significant（P ＞ 0.05）．The total mercury content in the muscle of Larimichthys crocea reared in different water bodies ranged from（0.013 4±0.007 2）mg/kg to（0.016 3±0.010 7）mg/kg，while the contents of methylmercury，inorganic arsenic，and total arsenic in the muscle were not detected．The results suggest that the cultivation of Larimichthys crocea in saline-alkaline water holds considerable potential for wider adoption. |
