Phytoplankton Species in Hong Kong Coastal Waters

325 in thickness and large decaying biomass might cause oxygen depletion in the water, resulting in great loss of various marine organisms. Phaeocystis globosa is capable to produce hemolytic toxins, which may result in negative influence on fisheries and public health. 生態與分佈 球形棕囊藻是廣泛分佈於溫帶和熱帶水域的浮游物種,在溫帶的大洋和近岸都有 發現。球形棕囊藻是紅潮原因種,2002年至2023年在香港海域形成20次紅潮。本物 種在全球範圍內也曾多次引發紅潮,紅潮產生泡沫和粘液會堵塞魚鰓,造成魚類死 亡。紅潮形成過程中泡沫可厚達數米,在紅潮後期分解的過程中會造成水體缺氧進 而給其他生物造成危害。球形棕囊藻可以分泌溶血性毒素,給漁業以及公眾健康帶 來風險。 Size Diameter:5 μm (solitary, motile stage); 7 μm (colony stage) (Tomas, 1997); 3-9 μm (Law, 2018); 3-3.5 μm (Al-Yamani and Saburova, 2019) Diameter of spherical colony: 2-8 cm (Tomas, 1997); 2 cm (Law, 2018); 4-7 cm (AlYamani and Saburova, 2019) 粒徑 直徑: 5微米(單細胞生活,可運動階段),7微米(群落階段)(Tomas, 1997);3 到9微米(羅秉全,2018);3到3.5微米(Al-Yamani and Saburova, 2019) 球狀群落直徑: 2到8釐米(Tomas, 1997);2釐米(羅秉全,2018);4到7釐米(AlYamani and Saburova, 2019) Synonyms 同種異名 No synonyms are currently included in AlgaeBase. 无同種異名。
