本文探讨了不同蛋白质含量的配合饵料对赤点石斑鱼（Epinephelusakaara）生长的影响。通过60d度验得出：在各配合饵料组中，蛋白质含量为49．52％的试验的相对增重率（46．84％）体长相对增长率（15．96％）、蛋白质效率（60．35％）和饵料转化率（29．85％）等均为最佳。配合饵料组鱼体肌肉营养成分（蛋白质、脂肪、氨基酸和鲜味氨基酸）也均优于对照组，而更接近野生鱼。经回归方程分析，赤点石斑鱼人工配合饵料中蛋白质最适含量为48．37％～49．24％。
This article explored the effects of different dietary protein contents on the growth of Epinephelusakaara. The 60d degree test showed that the relative growth rate (15.96%) and the protein efficiency (60%) of the relative weight gain rate (46.84%) of the test group with the protein content of 49.52% .35%) and feed conversion rate (29.85%) are the best. With the food group fish nutrition composition (protein, fat, amino acids and umami amino acids) are also better than the control group, and more close to the wild fish. The regression equation analysis, the Red Point grouper artificial diet with the optimum protein content of 48.37% to 49.24%.
