| 摘 要： | 对千年笛鲷Lutjanus sebae、红鳍笛鲷L.erythopterus和紫红笛鲷L.argentimaculatus及不同生长阶段千年笛鲷的含肉率、肥满度、比肝重及其肌肉生化成分进行了分析,结果表明,3种笛鲷的含肉率差异极显著,肥满度、比肝重和肌肉营养成分的差异较小,而对于不同生长阶段的千年笛鲷而言,其差异明显。肌肉粗蛋白、粗脂肪和水分含量的大小顺序均为红鳍笛鲷>紫红笛鲷>千年笛鲷。不同生长阶段的千年笛鲷,随着鱼体的生长,其含肉率增加,肥满度和比肝重降低;粗蛋白和粗脂肪含量增加,水分和灰分含量减少。

| Abstract: | Addressed rates,condition factors,hepatosomatic indexes and approximate compositions of muscles were analyzed to appraise and compare the nutritive value of emperor snapper(Lutjanus sebae),red snapper(L.erythopterus) and silver snapper(L.argentimaculatus).The results showed that the addressed rates and condition factors of emperor snapper,red snapper and silver snapper were 61.80%,68.00%,57.75% and 2.65,2.83,2.31,respectively.The addressed rate,condition factor and the contents of crude protein,and fat in muscle were higher in red snapper than those in other species.There were no significant difference in hepatosomatic indexes in three species.Emperor snapper increased addressed rates and contents of crude protein and fat of muscles with development,while the condition factors,hepatosomatic indexs and contents of moisture and ash decreased with the development of the fish. |
