摘要
对福建闽江口 50 个站位的海底沉积物样品进行分析,共鉴定出甲藻孢囊 17 种,隶属 7 属,主要的种类有锥状斯氏藻 ( Scrippsiella trochoidea ),科夫/无纹多沟藻 ( Polykrikos kofoidii/schwartzii )、斯氏膝沟藻 ( G. scrippsae )和具刺膝沟藻 ( Gonyaulax spinifera );锥状斯氏藻为最丰富的种;并检出有毒种塔玛亚历山大藻 ( Alexandrium tamarense )。研究结果表明,闽江口表层沉积物中的甲藻休眠孢囊主要分布在砂-粉砂-粘土沉积物类型中;有毒甲藻塔玛亚历山大藻有可能在每年 5—6 月、10—11 月对该海域的海洋生物和人类健康及生命安全构成潜在威胁,应加强监测。
We analyzed 50 sediment samples from the Minjiang Estuary, Fujian Province, and identified 17 species of 7 genera of dinoflagellate cysts. Scrippsiella trochoidea is the most dominant species, and Polykrikos kofoidii/schwartzii, Gonyaulax spinifera, G. scrippsae are also abundant. We also found the cysts of toxic Alexandrium tamarense. The results show that the dinoflagellate cysts are mainly distributed in the sand-silt-clay sediment from the Minjiang Estuary. The toxic algae—Alexandrium tamarenes might threaten marine organisms and human health and life in May—June and October—November every year and should be monitored with greater care.
