摘　　要：雪卡毒素是一类富集于海洋珊瑚礁鱼体内的聚醚类化合物,由底栖小型甲藻岗比亚藻产生,经海洋食物链传递代谢为雪卡毒素并使鱼类染毒。雪卡毒素毒性强,是已知的危害性较严重的海洋生物毒素之一。然而,长期以来该毒素产毒藻(岗比亚藻)在分类学领域存在诸多争议。本文由此对国际上现有研究结果进行系统整理与归纳,内容包括岗比亚藻的分类与分布、生理生态学、毒理学,并提出研究展望。本文重点阐述了岗比亚藻的地理区域扩张事实、与大型附着基质藻的关系、环境因子对其生长和产毒的影响、种内和种间的产毒特征差异等。在此基础上,结合我国在该领域的研究现状,提出建议和展望。Dinoflagellates of the genus Gambierdiscus produce gambiertoxins that metabolize into ciguatoxins and accumulate in coral reef fishes via marine food chain. Consumption of ciguatoxin-contaminated fish would cause ciguatera fish poisoning, which is a serious non-bacteria illness associated with seafood consumption worldwide. Currently, Gambierdiscus research in China remains poorly developed. The taxanomy of genus Gambierdiscus remains argumantive in the past several decades, especially in previous description of G. toxicus on species level. This paper reviews the taxonomy, geogrphical distribution, ecophyiology, toxicology, and future research direction, and highlighted the distribution expansion, the relationship between Gambierdiscus and macroalgae, environmental factors affecting Gambierdiscus growth and toxin production, and toxicity differences between intra- and inter-species.
