Accumulation of toxins responsible for amnesic shellfish poisonings in filter feeding bivalves was widely observed in Southeast Asia countries. Some diatoms were strongly suspected as causative agents, especially those belonging to the genus Pseudo-nitzschia, but recurrence of the toxins in shellfish could not be detected and then confirmation of the causative species was not finalized. Pyrodinium bahamense bloomed in wide areas intermittently, causing poisoning cases in several countries. In addition Alexandrium spp. were also detected as the causative organisms of paralytic shellfish poisoning. Benthic dinoflagellates causing ciguatera fish poisoning were found in wide areas and study on their distribution expansion mechanisms is considered as urgently necessary.

在东南亚国家，人们广泛观察到了导致失忆症贝类中毒的毒素的积累。某些硅藻被强烈怀疑是病因，尤其是属于伪nitzschia属的硅藻，但无法检测到毒素在贝类中的复发，然后无法确认该因子物种的确认。 Bahamense的Pyrodinium间歇性地在广阔的地区开花，在几个国家引起了中毒病例。另外，亚历山大属。也被发现为瘫痪贝类中毒的病因生物。在广泛的地区发现了引起Ciguatera鱼中毒的底栖鞭毛鞭毛，并研究其分布扩展机制被认为是迫切需要的。
