Substitution effect of Undaria pinnatifida with citrus peel by‐product (CPB) on growth, body composition and air exposure stressor of abalone was determined. A total of 1,080 abalone were distributed into 18 net cages. Five formulated diets were prepared in triplicate. The CPB0 diet contained 200 g/kg U. pinnatifida. The 250, 500, 750 and 1,000 g/kg U. pinnatifida were substituted with the equal amount of CPB, referred to as the CPB250, CPB500, CPB750 and CPB1000 diets, respectively. Finally, dry U. pinnatifida was prepared. Abalone were fed for 16 weeks and then subjected to air exposure stressor for 24 hr. The cumulative mortality of abalone was monitored for the following 4 days after 24‐hr air exposure. Survival, weight gain and specific growth rate (SGR) of abalone fed all formulated diets were greater than those of abalone fed the U. pinnatifida. The greatest weight gain and SGR were achieved in abalone fed the CPB500 diet. The chemical composition of the soft body of abalone was not affected by the experimental diets. Higher cumulative mortality was observed in abalone fed the CPB0 and dry U. pinnatifida at 16 hr after 24‐hr air exposure compared to abalone fed all other diets. In conclusion, U. pinnatifida could be completely substituted with CPB in abalone feed.

裙带菜与柑橘 (Citrus unshiu, Marcovitch) 果皮副产品在饲料中的替代作用对幼鲍的生长、身体成分和空气暴露应激源的影响 (Haliotis discus, Reeve 1846)

确定了用柑橘皮副产品 (CPB) 替代裙带菜对鲍鱼的生长、身体成分和空气暴露压力源的影响。总共有 1,080 只鲍鱼被分配到 18 个网箱中。一式三份制备五种配方饮食。CPB0 饮食含有 200 g/kg U. pinnatifida。250、500、750 和 1,000 g/kg 羽扇豆被等量的 CPB 替代，分别称为 CPB250、CPB500、CPB750 和 CPB1000 饮食。最后，制备了干燥的羽扇豆。鲍鱼被喂食 16 周，然后经受空气暴露压力源 24 小时。在暴露于空气 24 小时后的接下来 4 天内监测鲍鱼的累积死亡率。饲喂所有配方饲料的鲍鱼的存活率、增重和比生长率 (SGR) 均高于饲喂美国的鲍鱼。羽化。在饲喂 CPB500 饮食的鲍鱼中获得了最大的增重和 SGR。鲍鱼软体的化学成分不受实验日粮的影响。与喂食所有其他饮食的鲍鱼相比，在 24 小时空气暴露后 16 小时，在喂食 CPB0 和干燥 U. pinnatifida 的鲍鱼中观察到更高的累积死亡率。总之，在鲍鱼饲料中，羽扇豆可以完全被CPB替代。
