| 摘 要： | 3个野生大银鱼(Protosalanx hyalocranius) 群体样本于2010年12月采集于江苏太湖、黑龙江连环湖和吉林石头口门水库，分别对其主要营养成分进行了分析，从营养学的角度分析和评价不同地理群体大银鱼的品质。结果表明：3个地理群体之间大银鱼蛋白质含量和水分含量没有显著差异（P >0.05）；粗脂肪含量在3个群体间差异显著(P<0.05)。氨基酸及非必需氨基酸总量以江苏太湖群体中含量最高，分别占干重的76.14%和45.57%，黑龙江连环湖最低为71.54%和42.64%，黑龙江连环湖群体氨基酸总量与其它地理群体差异显著(P<0.05)。在脂肪酸总量上，3个地理群体差异不显著（P >0.05）。不饱和脂肪酸在总脂肪酸中的比例大小排列次序为黑龙江地理群体、太湖地理群体、吉林地理群体。吉林地理群体大银鱼的必需氨基酸指数、氨基酸评分和化学评分均高于另外2 群体。黑龙江地理群体大银鱼饱和脂肪酸及不饱和脂肪酸总量与其它群体呈现显著性差异(P<0.05) 。综合比较，江苏太湖及吉林群体大银鱼的营养价值要优于黑龙江群体。

| Abstract: | Three wild populations of Protosalanx hyalocranius were sampled from nature waters of Lianhuanhu lake in Heilongjiang Province(HL), Taihu Lake in Jiangsu Province(JT) , Shitoukoumen Reservoir in Jilin Province (JS)respectively. The capture was conducted in December 2010. The muscle nutritional composition of P. hyalocraniuss from three different areas had measured by conventional biochemistry. As a result, crude protein and moisture content of fish from three areas had no significant difference (P >0.05) , while there was significant difference in crude fat content among the three populations (P<0.05) . Fish from JT had the highest total and non essential amino acid contents (76.14%and 45.57%, dry weight) .The lowest total and non essential amino acid contents were 71.54% and 42.64%, of fish from HL. There was significant difference of flavor acids in JS compared with that in other two populations (P<0.05). There was no significant difference of total fatty acid content among the three populations (P >0.05) . Fish from JT had higher essential amino acid index, amino acid score and chemical score than those of the other two populations. There was significant difference of total saturated and unsaturated fatty acid contents in HLcompared with that in other two populations (P<0.05). Based on the clustering analysis, it was apparent that the nutritional quality of fish from JT and JL was better than that from HL. |
