摘　　要：在室内条件下研究了不同密度的塔玛亚历山大藻(Alexadrium tamarertse ATDH01)对南美白对虾(Penaeus vannamei)溞状幼体和仔虾的存活率影响.结果显示:塔玛亚历山大藻密度对南芙白对虾溞状幼体的存活率有明显的兰异,塔玛亚历山大藻藻细胞密度越高,存活率越低.在96h急性实验中,塔玛亚历山大藻对南美白对虾溞状幼体的半致死密度为7 500/mL;在密度12 000/mL以下对仔虾的存活率无显著的影响;在密度15 000/mL时存在显著影响.其本身的毒力经过小鼠生物检测法得每细胞为8.407×10^(-5)鼠单位(MU).In order to test toxicity effects of Ale：cadrium tamarense ATDH01 on nauplii of Penaeus vannamei. Set different concentrations of Ale：cadrium tamarense ATDH01 . The result indicated that culture of Alexadrium tamarense ATDH01 showed obvious impact on the survival of the nauplii of Penaeus vannamei. Higher concentration , higher survival. The tests were performed as 96 h static test with 96 h LC50 = 7 500/mL. Toxicity effects of Alexadrium tamarense ATDH01 on post larve of Penaeus vannamei were not insignicant below 12 000/mL concentration and impacted at 15 000/mL concentration. Testing with mouse detected method, the toxicity of Alexadrium tamarense ATDH01 was 8. 407×10^-5 MU/cell.
