| 摘 要： | 通过非离子氨氮对罗氏沼虾幼体的急性致毒试验表明：Ⅴ期幼体９６ｈ的半致死浓度（ＬＣ５０）值为１．１４ｍｇ／Ｌ，安全浓度（ＳＣ）值为０．１１ｍｇ／Ｌ；Ⅸ期幼体９６ｈ的ＬＣ５０值为１．４０ｍｇ／Ｌ，ＳＣ值为０．１４ｍｇ／Ｌ，建议在育苗期间加强水质管理，有效地控制水体中非离子氨氮的浓度。

| Abstract: | The acute toxicity test of ammonia nitrogen to larvae Macrobrachium rosenbergii was carried out in this paper. The results showed that the semi lethal concentration ( LC 50 ) of 96 h of the fifth zoea stage ( Z 5 ) was 1.14 mg/L, the safety concentration ( SC ) was 0.11 mg/L; and the LC 50 of 96 h of Z 9 and SC were 1.40 mg/L and 0.14 mg/L respectively . The report suggests that the available concentration of ammonia nitrogen was below 0.10 mg/L. |
