本实验通过水体与育苗池消毒、合理投喂、科学防病以及育苗池水质理化因子（DO、pH、NH 4＋-N、NO 2--N、COD）和病原生物（弧菌、WSSV等）的实时监测,对凡纳滨对虾高健康育苗模式做了一定的探索。实验结果显示,整个育苗期间育苗池水溶解氧保持在4.2～5.8mg/L（平均5.01±0.63mg/L）,pH保持在8.04～8.38（平均8.13±0.11）;NH 4＋-N控制在0.15～1.21mg/L（平均0.51±0.40mg/L）,NO 2--N控制在0.15～1.21mg/L（平均0.05±0.02mg/L）,COD控制在1.56～7.02mg/L（平均4.75±2.18mg/L）。异养细菌数200～91000cfu/mL,弧菌0～6980cfu/mL。投放无节幼体4600×104尾,收获虾苗1280×104尾,成活率达27.8%,且虾苗体质健康,活力旺盛,无携带病毒。
本實驗通過水體與育苗池消毒、閤理投餵、科學防病以及育苗池水質理化因子（DO、pH、NH 4＋-N、NO 2--N、COD）和病原生物（弧菌、WSSV等）的實時鑑測,對凡納濱對蝦高健康育苗模式做瞭一定的探索。實驗結果顯示,整箇育苗期間育苗池水溶解氧保持在4.2～5.8mg/L（平均5.01±0.63mg/L）,pH保持在8.04～8.38（平均8.13±0.11）;NH 4＋-N控製在0.15～1.21mg/L（平均0.51±0.40mg/L）,NO 2--N控製在0.15～1.21mg/L（平均0.05±0.02mg/L）,COD控製在1.56～7.02mg/L（平均4.75±2.18mg/L）。異養細菌數200～91000cfu/mL,弧菌0～6980cfu/mL。投放無節幼體4600×104尾,收穫蝦苗1280×104尾,成活率達27.8%,且蝦苗體質健康,活力旺盛,無攜帶病毒。

In this paper,the healthy breeding technology of Litopenaeus vannamei was studied.In this experiment,the breeding mode were investigated by the scientific plan and execution of programs,such as water and pond cleaned,food reasonable fed,disease controlled and the environment-related factors monitored by real-time.The results showed that the DO was kept in 4.2～5.8 mg/L（mean 5.01±0.63 mg/L）,and pH was 8.04～8.38（mean 8.13±0.05）,respectively.The amount of NO-2-N,NH＋4-N and COD were controlled within the range of 0.15～1.21mg/L（mean 0.05±0.02 mg/L,0.15～1.21mg/L（mean 0.51±0.40mg/L）and 1.56～7.02mg/L（mean 4.75±2.18mg/L）,respectively.The total number of bacteria and vibrio were 200～91000 cfu/mL and 0～6980cfu/mL.There was 27.8% survival rate which 12.8 million larvae were harvested from 46 million nauplii in high healthy breeding.This larvae was health,vitality and strong.
