An investigation of the 'green tide' algae along the land coastline area of Jiangsu Province was carried out during December 2012 to May 2013. The results showed that 'green tide' algae appeared at 26.09% of the survey sites, and covered 22.83% of the investigated coastline. Green tide algae grew in coastal embankments, breeding dam and shallow marsh with relatively sparse vegetation. The species composition of the 'green tide' algae included Ulva prolifera, Ulva flexuosa and Ulva linza. Ulva prolifera was the dominant species from January to March, and Ulva flexuosa was the dominant species from April to May. Ulva linza was found to have low wet weight biomass throughout the whole investigation time. In May, the wet weight biomass of the attached 'green tide' algae was about 36.7 t in coastline, even less than 10% of floating 'green tide' algae. The wet weight biomass of Ulva flexuosa originally growing from coastline was about 0.6% of that of floating Ulva flexuosa. Therefore, dam would not be the major source for the occurrence of green tide. ©, 2014, Science Press. All right reserved.
