| 英文摘要 | Over the past two decades, harmful algal blooms (HABs) have frequently occurred in the coastal waters off Qinhuangdao (CWQ) in the Bohai Sea, with paralytic shellfish toxins (PSTs) in shellfish often exceeding safety standards. However, research on the biodiversity and seasonal variations of toxic HAB species in this area remains scarce, significantly hindering studies on the prevention and control of toxic HAB disasters. Since 2014, we have systematically identified and studied toxic microalgae in the CWQ. However, the historical survey voyages were primarily conducted during the summer, lacking continuous monitoring and research throughout the entire year. From March 2022 to February 2023, monthly samples were collected from the CWQ to investigate the biodiversity, spatiotemporal distributions, and environmental drivers of HAB species, utilizing metabarcoding methods. A total of 3711 amplicon sequence variants (ASVs) across nine phytoplankton phyla were identified in this research, with Dinoflagellata and Chlorophyta being the dominant phyla. Among the 251 annotated phytoplankton species, 51 were identified as potentially HAB species, including 18 capable of producing toxins or potentially toxic substances. Notably, the HAB species Teleaulax acuta was found to be distributed throughout the region year-round, exhibiting a relatively high abundance. Additionally, several toxic species from the genus Alexandrium (PSTs), Pseudo-nitzschia (domoic acid, DA), and Karenia (Brevetoxin, BTX), were widely detected in the CWQ from August to December 2022. Temperature and salinity were identified as critical environmental drivers influencing the distribution and seasonal succession of dominant HAB species. In summary, at least 129 potentially HAB species were identified in the CWQ from 2014 to 2023, including 43 toxigenic species or those with potentially toxic effects, posing a high risk of toxic HAB outbreaks. This research underscores the importance of monitoring toxic HAB species for the prevention and control of HAB events in coastal sea areas. |
