Dietary inclusion effects of various levels of jack mackerel meal (JMM) on growth, feed utilization, biochemical composition, and innate immune response of rockfish were determined. The control (Con) diet included 550 g/kg fish meal (FM). Ten, 30, 50, 100, 200, 400, 600, and 1000 g/kg of JMM were included in the Con diet, referred to as the JMM₁₀, JMM₃₀, JMM₅₀, JMM₁₀₀, JMM₂₀₀, JMM₄₀₀, JMM₆₀₀, and JMM₁₀₀₀ diets, respectively. Eight hundred and ten fish (initial mean weight of 2.3 g) were distributed into 27 flow-through tanks. The experimental diets were assigned to triplicate groups of fish. Fish were hand-fed for 8 weeks. Weight gain of fish fed the JMM₄₀₀ diet was statistically better than that of fish fed the Con, JMM₁₀, JMM₃₀, JMM₅₀, JMM₁₀₀, and JMM₂₀₀ diets. Feed consumption of fish fed the JMM₄₀₀ diet was statistically higher than that of fish fed the Con, JMM₁₀, JMM₃₀, and JMM₅₀ diets. Dietary inclusion of JMM did not influence feed utilization, biochemical composition, and innate immune responses of fish. In conclusion, inclusion of JMM up to 400 g/kg of FM in diet improved growth and feed consumption of rockfish, and dietary optimum inclusion levels of JMM were estimated to be 396.7 and 403.1 g/kg based on regression analysis of weight gain and feed consumption, respectively.

竹荚鱼、竹荚鱼、石斑鱼饲料中的膳食对生长、饲料利用率、生化成分和先天免疫反应的影响

确定了不同水平的竹荚鱼粉（JMM）的膳食添加对石斑鱼生长、饲料利用率、生化成分和先天免疫反应的影响。对照 (Con) 饮食包括 550 g/kg 鱼粉 (FM)。Con饮食中包含10、30、50、100、200、400、600和1000g/kg的JMM，称为JMM 10、JMM 30、_JMM 50 _、 JMM ₁₀₀、_JMM 200 _、 JMM ₄₀₀、分别为JMM ₆₀₀和 JMM ₁₀₀₀饮食。810 条鱼（初始平均重量为 2.3 克）被分配到 27 个流通池中。实验饮食被分配给三组鱼。鱼被人工喂养8周。_{饲喂 JMM 400}饲料的鱼的体重增加在统计学上优于饲喂 Con、JMM ₁₀、JMM ₃₀、JMM ₅₀、JMM ₁₀₀和 JMM ₂₀₀饲料的鱼。_{饲喂 JMM 400}日粮的鱼的饲料消耗量在统计学上高于饲喂 Con、JMM ₁₀、JMM ₃₀和 JMM ₅₀日粮的鱼的饲料消耗量。日粮中添加 JMM 不会影响鱼类的饲料利用率、生化成分和先天免疫反应。总之，在日粮中添加高达 400 g/kg FM 的 JMM 可改善石斑鱼的生长和饲料消耗，根据增重和饲料的回归分析，日粮中 JMM 的最佳添加水平估计为 396.7 和 403.1 g/kg分别消费。
