中文摘要	研究了有毒赤潮藻塔玛亚历山大藻Alexandrium tamarense对甲壳动物卤虫的干重及能值的影响。实验表明,经过18h的染毒实验,7 500尾卤虫Artemia parthenogenetica在水体中有塔玛亚历山大藻细胞或过滤液(细胞密度均为200cells.ml-1)存在的情况下,其总干重及总能值的增加明显受到抑制。卤虫总干重,对照组增加0.010 4g,而滤液组和藻细胞组均增加了0.002 2g,仅为对照组的21.1%;卤虫总能值,对照组增加0.143 5kJ,而滤液组和藻细胞组则分别增加0.018 0kJ和0.056 8kJ,分别为对照组的39.5%和12.5%。经SAS软件分析,塔玛亚历山大藻细胞对卤虫总干重的影响与对照组比较有显著性差异(p=0.037 0),而对其总能值增加则无显著差异(p=0.1251);而塔玛亚历山大藻过滤液对卤虫的总干重、总能值的增加与对照组都有显著性差异(p分别为0.021 5和0.013 5)。另外,无论是藻细胞或是过滤液对卤虫的比能值均无影响。有毒塔玛亚历山大藻使卤虫总干重减少可影响其他相关海洋动物的食物供给,而对卤虫能值的影响则表明毒藻可改变食物链中能量的传递效率,从而影响处于较高营养层的生物。研究还显示该藻的不利影响可出现在赤潮发生期及消退期,这为全面了解赤潮危害提供新的视角。; The effects of a red tide causing alga —Alexandrium tamarense on the dry weight and energy of Artemia parthenogenetica were studied.The results showed that the increases of total dry weight and total energy of 7 500 individuals of Artemia parthenogenetica were significantly inhibited when they were cultured for 18 hours in the mediums with and without the cells of Alexandrium tamarense(cell abundance of 200 cells·ml-1).So far as the total dry weight of Artemia parthenogenetica is concerned,0.010 4g increase was obtained for the control group,while only 0.002 2g increase was obtained for both the two experimental groups,only accounting for 21.1% of the increase of the control group.The total energy value increase was 0.143 5kJ for the control group,and was 0.018 0kJ and 0.056 8kJ respectively for the groups cultured in the mediums with and without the algal cells,only accounting for 39.5% and 12.5% of the increase of the control group respectively.According to the SAS analysis,compared with the control group,the experimental group with cells of Alexandrium tamarense had significant influence on the total dry weight(p=0.037 0) but not on the total energy values(p=0.125 1)of Artemia parthenogenetica,while the medium without the algal cells significantly affected both the total dry weight(p=0.021 5) and the total energy values(p=0.013 5) of Artemia parthenogenetica.In addition,both the mediums with and without the algal cells had no impact on the calorific values of Artemia parthenogenetica.Therefore,it is suggested that the negative effect of the poisonous alga—Alexandrium tamarense on the increase of dry weight of Artemia parthenogenetica may influence the development of the other aquatic animals which feed on them,and then influence the numbers of these animals.In addition,the energy decrease of Artemia parthenogenetica may change the energy transfer through food chain and consequently affect the animals at higher nutrition levels even though the numbers of zooplanktons such as Artemia parthenogenetica were not significantly affected.The negative influences of both the algal cells and the filtrate imply that the negative effect of red tide on Artemia parthenogenetica —an important feed living thing will occur not only during algal bloom periods but also at the time after red tides subsidise.; 【作者单位】厦门大学生命科学学院；集美大学水产学院福建厦门361005；集美大学水产学院；福建厦门361021；厦门大学近海海洋环境科学国家重点实验室；福建厦门361005；【作者英文名】ZHOU Li-hong1,2,3,WANG Xin1,3,ZHENG Tian-ling1,3*,CHEN Xiao-sheng2(1.School of Life Science,Xiamen University,Xiamen 361005,China;2.Fishery College,Jimei University,Xiamen 361021,China;3.State Key Laboratory of Marine Environmental Science,Xiamen 361
