| 摘 要： | 以厦门西海域养殖的翡翠贻贝为实验对象,在实验室内对塔玛亚历山大藻(Alexandrium tamarense(Lebour)Balech)采用单种培养技术,运用“麻痹性贝毒小白鼠生物检测法”进行毒性实验,研究了塔玛亚历山大藻对翡翠贻贝的麻痹性贝毒的毒力,藻密度为1×105个/dm3时,白鼠未死亡;藻密度为1×106个/dm3时,白鼠发生死亡.厦门西海域近年来暴发的赤潮一般起始于局部海区无害硅藻类浮游植物,在生态环境恶化下,硅藻类赤潮在生存竞争中消退,最终暴发有害赤潮.以试验结果为依据,根据厦门海域实际情况,参考各国贝毒临界值行动标准,提出适合南方赤潮多发区塔玛亚历山大藻的麻痹性贝毒藻密度预警值为1×105个/dm3.

| Abstract: | Taking the blue mussel(Mytilus edulis) cultured in western Xiamen waers and Alex andrium tamarense(Lebour) Balech monospecies laboratory cultured as the experimental objects,the PSP toxicityof A.tamarense on blue mussel is studied following the standard method of PSP mouse bioassay developedby the Association of Official Analytical Chemists(AOAC).The results indicate that the mice survived when the density of A.tamarense cells was lower than 1×105cells/dm3 and the mice died when the density was higher than 1×105cells/dm3.The pastrecord of red tide evolution in western Xiamen watersshows a general trend of starting from the bloom of non toxic plankto nic diatoms in local waters and resulting in harmful red tide bloom due to the fade of planktonic diatom which f ailed in the survival competitionin the unfavor able and deteriorated ecoenvironment.On the basis of experiment al results and natural environment of Xiam en waters and by making reference to the critical criteria of shellfish toxins in variousstates,a prewarning value 1×105cells/dm3 of A.tamarense PSP in Xiamen waters is proposed. |
