摘要
对1997年秋～1998年春广东沿海多次赤潮发生期间的几种优势赤潮藻类进行了形态学和分类学研究。1种为我国首次报道引发赤潮的定鞭金藻类（Prymnesiophytes）--球状棕囊藻（Phaeocystiscf.globosa）。另有甲藻类7种，其中裸甲藻目（Gymnodiniales）3种：米氏裸甲藻（Gymnodiniumcf.mikimotoi）、环节环沟藻（Gyrodimiuminstriatum）及PhaePolyk－rikoshartmanii;鳍藻目（Dinophysiales）1种：具尾鳍藻（Dinophysiscaudata）；原甲藻目（Pro－rocentrales）2种：海洋原甲藻（Prorocentrummicans）、利玛原甲藻（Prorocentrumlima）；多甲藻目（Peridiniales）1种：链状亚历山大藻（Alexandrumcatenella）。以上几种藻类引发的赤潮均为有害赤潮，其中球状棕囊藻、米氏裸甲藻和链状亚历山大藻能产生毒素，形成有毒赤潮。
A taxonomic study on 8 species of harmful red tide causative algae was undertaken. Samples were collected from Guangdong coast of South China Sea between October 1997 and April 1998 When red tides occurred in those areas. One spedes of Prymnesiophytes (Phaeocystis of. globosa),which was reported to cause red tide in China for the first time. The others were all dinoflagellates,three of which were toxic. They were 3 species of Gymnodiniales: Gymnodinium mikimotio, Gyrodinium instriatum and Phaepolykrikos hartmanii; 1 species of Dinophysiales: Dinophysis caudata; 2 species of Prorocentrales: Prorocentrum micans and Prorocentrum lima; 1 species of Peridiniales:Alexandrum catenella.
