孢囊指失去鞭毛和游泳能力的不动细胞。甲藻孢囊在许多甲藻生活史中都存在,孢囊的存在是浮游植物生物量季节性增减的重要原因之一(Ferando Rubino et al,2000)。详细调查孢囊的数量分布情况不仅可以作为海区曾发生赤潮的证据,也有助于预报赤潮的发生,对于研究赤潮机制和预报监测工作提供数据。目前国际上共记录甲藻孢囊160余种,其中海洋甲藻孢囊90种左右。我国有关孢囊的研究起步较晚,相关的报道也较少。20世纪90年代齐雨藻等(1996)对我国东南沿海甲藻孢囊种类首次进行描述,随着有关甲藻孢囊研究工作的进一步开展,到目前为止,我国学者已对东南沿海,如大鹏湾,大亚湾,厦门湾,长江口,拓林湾,闽江口,深圳湾,三沙湾等赤潮多发区进行了孢囊种类及其分布的研究(肖咏之等2003.王朝晖等2003a、2003b、2004, 林元烧2002,方齐等2003、2004,顾海峰等2004,蓝东兆等2005)。
