Abstract

Abstract:

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 1.6×106 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.
