浙江近海浮游植物与赤潮生物研究Ⅲ．台州列岛附近海域

Studies on Phytoplankton and Red Tide Causative Species in Zhejiang Coastal WaterⅢ.Taizhou Archipalego Water

１９９０年春季和秋季在台州列岛附近海域进行了两次采样调查，共检出浮游植物６０种，隶于２５属。春季浮游植物的平均丰度为１０．６３×１０￣４个／ｍ￣３，最高达２７．５×１０￣４个／ｍ￣３，优势种为夜光藻Ｎｏｃｔｉｌｕｃａｓｃｉｎｔｉｌ－ｌａｎｓ和汉氏束毛藻Ｔｒｉｃｈｏｄｅｓｍｉｕｍｈｉｌｄｅｂｒａｎｔｉｉ等；秋季浮游植物平均丰度为１８．７×１０￣４个／ｍ￣３，最高达４５．９６×１０４个／ｍ￣３，优势种为夜光藻及角藻等。春秋两季均存在多种赤潮生物。

Abstract A survey on phytoplankton in Taizhou Archipalego water was carried out in Mayand October,1990.60 species belonged to 25 genera were identified in total.Among them,15 were red tide causative species,The mean density of the phytoplankton in spring was 10.63×10￣4 cells/m￣3 and the dominant species were Noctiluca scintillans,Trichdoresmium hildebrantii, etc.The mean density of the phytoplankton in autumn was 18.74 × 10￣4 cells/m￣3 and the dominantspecies were Nortiluca scintillans,Ceratium fusus,Ceratium furca, etc. Some red tide causativespccies occured in the two seasons.
