根据50年来的记录，对有害针杆藻Chattonella引起的赤潮及其对渔业的影响进行了重新评估，以了解该有害物种在西太平洋的分布和经济影响。自1969年以来，在东亚已经记录了造成渔业损害的Chattonella水华，而自20世纪80年代以来，它们仅在东南亚有记录。查顿氏菌在六个东南亚国家（印度尼西亚、马来西亚、菲律宾、新加坡、泰国和越南）均有记录，1980- 1990年代主要是养殖虾的大规模死亡，2000- 2010年代主要是养殖鱼的大规模死亡。这些事件已被报道的名称为C。antiqua，C.马里纳角，澳-地ovata、卵圆隐翅虫C.和Chattonella sp.，由于显微镜下物种鉴定的困难，许多没有分子数据支持。确定C. marina complex和C.此外，还对来自印度尼西亚、马来西亚、日本、菲律宾、俄罗斯、新加坡和泰国的培养物进行了分子系统发育和显微镜观察。结果表明，只有C.在东亚（中国、日本、韩国和俄罗斯）已发现了滨岸复合体，而C. marina complex（印度尼西亚和马来西亚）和C.在东南亚发现了salsa（菲律宾、新加坡和泰国）。粘液囊的排出被认为是C. subsalsa，但在我们的C.从印度尼西亚、马来西亚、日本和俄罗斯分离出来的码头。与此同时，在东南亚同时出现的两种有害的Chattonella物种，这是很难区分仅仅基于它们的形态，表明分子鉴定的Chattonella基因型的重要性，以进一步了解它们的分布和负面影响。
Red tides and associated fisheries damage caused by the harmful raphidophyte Chattonella were reassessed based on the documented local records for 50 years to understand the distribution and economic impacts of the harmful species in the Western Pacific. Blooms of Chattonella with fisheries damage have been recorded in East Asia since 1969, whereas they have been only recorded in Southeast Asia since the 1980s. Occurrences of Chattonella have been documented from six Southeast Asian countries, Indonesia, Malaysia, Philippines, Singapore, Thailand and Viet Nam, with mass mortalities mainly of farmed shrimp in 1980-1990s, and farmed fish in 2000-2010s. These occurrences have been reported with the names of C. antiqua, C. marina, C. ovata, C. subsalsa and Chattonella sp., owing to the difficulty of microscopic species identification, and many were not supported with molecular data. To determine the distribution of C. marina complex and C. subsalsa in Southeast Asia, molecular phylogeny and microscopic observation were also carried out for cultures obtained from Indonesia, Malaysia, Japan, Philippines, Russia, Singapore and Thailand. The results revealed that only the genotype of C. marina complex has been detected from East Asia (China, Japan, Korea and Russia), whereas both C. marina complex (Indonesia and Malaysia) and C. subsalsa (Philippines, Singapore and Thailand) were found in Southeast Asia. Ejection of mucocysts has been recognized as a diagnostic character of C. subsalsa, but it was also observed in our cultures of C. marina isolated from Indonesia, Malaysia, Japan, and Russia. Meanwhile, the co-occurrences of the two harmful Chattonella species in Southeast Asia, which are difficult to distinguish solely based on their morphology, suggest the importance of molecular identification of Chattonella genotypes for further understanding of their distribution and negative impacts.
