摘要

分别在2014年5-7月对位于海南省昌江养殖基地6口对虾养殖池塘（H1-H6）和2014年8-10月对位于广东省珠海市养殖基地的9口对虾养殖池塘（Z1-Z9）连续采集对虾养殖水样，对氨氮、亚硝氮、硝氮等理化因子进行检测，记录养殖期间天气、饵料投喂、对虾发生肝胰腺坏死症（Hepatopancreas necrosis syndrome，HPNS）等情况。统计分析表明，氨氮与肝胰腺坏死症的发生呈显著相关。养殖过程中三态氮的变化较大，随着养殖时间和饲料投喂的增加，养殖水体中的氨氮和总氮呈上升的趋势。养殖第70-85天， H1-H6先后不同程度发生HPNS，对虾发病时各池塘水体氨氮质量浓度为0.29~0.74 mg/L，发病期间氨氮最高值0.42~1.02 mg/L，H1-H6同时采取控料措施后，控料后第5天的氨氮含量比控料前氨氮含量最高值分别降低了60.03%~84.89%，HPNS得到有效的控制。H1-H6实验塘下雨前第2天至当天氨氮含量均小于0.2 mg/L，下雨后第1天均明显增加，增幅最低的H5号塘氨氮含量达到0.477 mg/L，增幅最大的H3号塘氨氮含量达到1.35 mg/L。Z1-Z9观测结果显示，9个实验塘的氨氮平均含量在台风前第1天为0.2 mg/L

而台风过后第3天其氨氮平均含量达到0.66 mg/L。台风过后对虾出现空肠空胃、吃料缓慢等HPNS症状。当饵料过度投喂，遇上下雨天、台风等极端天气，水中的氨氮含量上升明显，并伴随HPNS发生。

Abstract

Continuous collection of shrimp-breeding pond water samples was respectively done and detected in 6 ponds(H1-H6) in aquaculture base located in Dongfang

Hainan from May to July 2014

as well as 9 ponds(Z1-Z9) in Zhuhai

Guangdong. Detect the concentration of ammonia nitrogen

nitrite nitrogen

nitrate nitrogen as well as other physical and chemical factors were also detected in these shrimp farming ponds. The weather

feeding management

the outbreak of hepatic pancreas necrosis syndrome(HPNS) and its response management were recorded during the period of aquaculture. Result of the statistical analysis showed that ammonia and HPNS was significantly correlated. Three different forms of nitrogen had a significant change in the aquaculture period. With the increase of time and amount of feeding

ammonia and nitrogen in the aquaculture water showed an upward trend. In the first 70~85 days of aquaculture

HPNS successively occurred in varying degrees in H1-H6. The H1-H6 ammonia nitrogen ranged 0.29~0.74 mg/L when the HPNS occurred. The highest value of ammonia ranged 0.42~1.02 mg/L during the onset. After the feeding control taken in H1-H6 when the HPNS outbreak

the ammonia nitrogen concentration in five days was 60.03%~84.89% lower than its highest concentration during onset

respectively. HPNS was effectively controlled. The ammonia nitrogen of H1-H6 were less than 0.2 mg/L at the two days before raining days and the ammonia nitrogen increased dramatically after rain. The ammonia nitrogen in H5 which has increased least was 0.477 mg/L and the ammonia nitrogen in H3 which has increased most was 1.35 mg/L. Z1-Z9 experiment results showed that the average concentration of ammonia at the day before the typhoon was 0.2 mg/L whereas the average concentration of ammonia at the third day after the typhoon reached 0.66 mg/L. After typhoons

vannamei appeared jejunogastric and inappetence which are obvious symptoms of HPNS. The concentration of ammonia rose significantly and was accompanied with the occurrence of HPNS when the ponds were over-feeded or when typhoon or rain came.
