多环旋沟藻Cochlodinium polykrikoides赤潮在全球频繁爆发.2006年10-11月间,在广东珠海海域爆发的双胞旋沟藻Cochlodinium geminatum赤潮则较为少见.双胞旋沟藻赤潮发生于富营养的近岸水体,赤潮发生区内水温变化范围23.41-27.54℃,盐度变化范围15.49-17.92.双胞旋沟藻的细胞密度随温度和盐度的升高而显著升高,最高细胞密度达1.6×10~6个·L~(-1).在赤潮发生后期,海区水温下降及群落中红色中缢虫Mesodinium rubrum 数量的上升,可能是导致双胞旋沟藻赤潮衰亡的重要原因.

Blooms of Cochlodinium polykrikoides occur frequently around the world.During October to November,2006,an unusual bloom of Cochlodinium geminatum occurred in the coastal eutrophicated waters in Zhuhai,Guangdong.The water temperature and salinity in the bloom zone ranged between 23.41-27.54℃ and 15.49-17.92 psu,respectively.The density of C. geminatum increased significantly with water temperature and salinity and reached to the highest density of 1.6×10~6 ind·L~(-1).During the latter period of bloom,the decrease of water temperature and the increase of density of Mesodinium rubrum might be responsible for the dissipation of the C. geminatum bloom.
