摘　　要：在 2 2 5～ 2 7 3℃、盐度 2 4 5～ 2 9 3条件下 ,对养殖大海马 (Hippocampuskuda)进行了饥饿及投喂方式对其生存和生长影响的实验。成鱼 (体长 10～ 12cm)持续饥饿后 10 9d全部死亡 ,死亡高峰在 80～ 84d ;幼鱼 (体长 4～ 6cm)饥饿后死亡高峰在 6 5～ 72d ,97d全部死亡 ;初生苗 (体长 0 7～ 0 9cm)持续饥饿后有两个死亡高峰 ,分别为 3～ 4d和 7～ 8d ,13d全部死亡。成鱼、幼鱼和初生苗的饥饿不可逆点 (PNR ,thePointofNo return)分别为 85d、70d和 7d ;初生苗饥饿后影响存活率 ,持续饥饿 7d后存活率为 0。每天仅投喂两次或间隔 1d等投饵方式基本不影响幼鱼的生长 ,是可以考虑使用的投喂方法。To reveal the effects of starvation and feeding modes on the survival and growth of seahorse,the experiments Hippocampus kuda were conducted on condition of 23.5～ 27.3 ℃,salinities 24.5～29.3.The adult fish all died after starvation for 101 days,and the peak of death was at 80～84 day.The larvae all died at 97 day and the peak at 65～72 day,and the newborn larvae all died at 13 day but had two peaks of death. The Point of No-return of adult fish,larvae and newborn larvae were 85、70 and 7 days respecttively,meanwhile the effects of starvation on survival rate of the newborn larvae were significant.The feeding mode effected the growth rate of seahorse dominantly,the survival rate was zero after 7 days’ starvation.The feeding modes,for example,feeding twice a day or feeding 1 day and stop 1 day,could be selected because of making no difference significantly.
