比较分析了分别投喂小杂鱼和人工饲料的两组褐牙鲆肌肉营养成分,旨在为褐牙鲆的营养需求研究及其饲料研制提供参考.结果显示:摄食小杂鱼组的水分含量显著低于摄食人工饲料组(P<0.05),而粗蛋白和粗脂肪含量显著高于摄食人工饲料组(P<0.05),粗灰分含量在两组间差异不显著(P>0.05);两组褐牙鲆的氨基酸组成基本一致,均含有18种氨基酸,必需氨基酸指数(EAAI)分别为71.15和70.47,其构成比例符合FAO/WHO的标准.摄食小杂鱼组褐牙鲆中检测到11种饱和脂肪酸(SFA)、6种单不饱和脂肪酸(MUFA)和9种多不饱和脂肪酸(PUFA);摄食人工饲料组中检测到11种SFA、7种MUFA和9种PUFA.摄食小杂鱼组的∑ω3PUFA[(30.39 4±2.29)%]显著低于摄食人工饲料组[(34.40±3.32)%](P<0.05),其中小杂鱼组的EPA+DHA的总量为(29.27±2.33)%,显著低于摄食人工饲料组的(33.47±3.36)%(P<0.05);摄食小杂鱼组的∑ω6PUFA为(6.01 4±0.31)%,显著高于摄食人工饲料组的(5.06 4±0.37)%(P<0.05).综合来看,两组褐牙鲆均含有丰富的各种营养成分,摄食小杂鱼组的粗蛋白、粗脂肪和氨基酸营养较好,而摄食人工饲料组的多不饱和脂肪酸营养较好,两者各有优势.

This paper compared nutritional components in the muscles of two groups of Paralichthys olivaceus fed on artificial diet(group Ⅰ)and fresh fish(group Ⅱ)respectively.The resuhs showed that the content of moisture of group Ⅰ was significantly lower than that of group Ⅱ while the latter's content of crude protein and crude lipid were significantly higher(P<0.05).There was no significant difference in the content of crude ash between the two groups(P>0.05).The component of amino acids was similar between the two groups (P>0.05).The component ofthe essential amino acids(EAA)meets the standard of Food and Agriculture Organization of the United Nations(FAO)/Word Health Organization(WHO).Based on the nutrition evaluation of amino acids score(AAS)and chemical score(CS),the limited amino acids of these two groups were(Met+Cys).The essential amino acids index(EAAI)was also similar between the two groups(P>0.05),i.e.71.15 for the group fed on fresh fish and 70.47 for the group fed on artificial diet,respectively.There were 11 kinds of saturated fatty acids(SFA),6 kinds of mono-unsaturated fatty acids(MUFA)and 9 kinds of poly unsaturated fatty acids(PUFA)in group I,while 11 kinds of SFA,7 kinds of MUFA and 9 kinds of PUFA were found in group Ⅱ.There were significant differences between group I and group Ⅱ in ω3PUFA and ω6PUFA(P<0.05).The proportions of ω3PUFA and ω6PUFA were(30.39.4±2.29)%and 6.01±0.31%in group I and(34.40±3.32)%and(5.06±0.37)%in groupⅡ,respectively.It was observed that the proportion of EPA & DHA in group I was lower than that of group Ⅱ,that was(29.27±2.33%)in group Ⅰ and(33.47±3.36)%in group Ⅱ(P<0.05).The present study indicated that both groups contained abundant amino acids and fatty acids,but the fish fed on fresh fish had higher nutritional components in crude protein,amino acids while the fish fed Oil artificial diet had higher nutritional components in PUFA.
