摘要： 评估跑道式池塘循环水养殖宝石鲈的肌肉营养品质和健康水平，为跑道式池塘循环水养殖模式对宝石鲈肌肉营养品质的调控以及健康养殖提供参考依据，以推进宝石鲈产业的发展。采用生理生化的方法，对跑道式池塘循环水养殖模式下的宝石鲈的生长指标、肌肉营养成分、血清生化指标进行了测定，并与普通池塘养殖的宝石鲈进行了比较。结果显示：跑道式池塘循环水养殖宝石鲈的生长较有优势，特定生长率（1.44%/d）和存活率（90%）均较高，饲料系数（1.2）较低；跑道式池塘循环水养殖模式下宝石鲈肌肉粗蛋白、水分和灰分含量显著升高（P<0.05），粗脂肪含量显著降低（P<0.05）；显著降低了血清谷丙转氨酶(ALT)和谷草转氨酶(AST)活性（P<0.05），显著升高了血清补体C的含量（P<0.05）。研究表明，跑道式池塘循环水养殖模式有助于提高养殖宝石鲈的品质，提升其机体的健康状况。

Abstract: The purpose of this study was to evaluate the nutritional quality of muscle and the level of health of Scortum barcoo under in-pond raceway aquaculture systems, and to provide a reference for the regulation of muscle nutritional quality and healthy aquaculture of Scortum barcoo by in-pond raceway aquaculture systems, so as to promote the development of Scortum barcoo industry. The growth indexes, muscle nutrients and serum biochemical parameters of Scortum barcoo under in-pond raceway aquaculture systems were measured by physiological and biochemical methods, and the comparison was made with Scortum barcoo under common pond culture. The results showed that the Scortum barcoo under in-pond raceway aquaculture systems grew faster, the specific growth rate (1.44%/d) and survival rate (90%) were higher and the feed conversion(1.2) was lower. The muscle crude protein, water and ash content of Scortum barcoo under in-pond raceway aquaculture systems increased significantly (P<0.05), and the content of crude fat decreased significantly (P<0.05). The activities of ALT and AST in serum were decreased significantly (P<0.05) and the content of serum complement C was increased significantly (P<0.05). The results showed that in-pond raceway aquaculture systems were helpful to improve the quality and health of Scortum barcoo.

Key words: Scortum barcoo, in-pond raceway aquaculture systems, nutritional components, serum biochemical parameters.
