“…Optimal temperatures for growth of Ulva (including U. prolifera) are 15 to 20°C and favourable temperatures are 10 to 22°C (e.g. Taylor et al, 2001;Largo et al, 2004;Liang et al, 2008;Luo et al, 2012). In this study, at Rudong, where Ulva growth was the greatest, temperature was significantly warmer during the day (by about 2°C) than Sheyang and Haitou.…”

“…200 to 600 kg ha −1 ). In the early stages of greentide development, several green algal species including U. prolifera, U. intestinalis and Ulva linza were identified from the floating algal patches, however the subsequent massive blooms were reported to be comprised almost exclusively of U. prolifera Ding and Luan, 2009;Luo et al, 2012;Zhao et al, 2013). Fan et al (2015) found six species of fouling green algae on Pyropia rafts and that the dominant species shifted from Ulva compressa, U. intestinalis and Ulva clathrata to Blidingia sp.…”

a b s t r a c t a r t i c l e i n f oAnnually recurrent green-tides in the Yellow Sea have been shown to result from direct disposal into the sea of fouling Ulva from Pyropia aquaculture. The role abiotic factors play in Ulva biomass accumulation on rafts was studied to find ways to mitigate this problem. Dissolved inorganic nitrogen (DIN) was very high at all sites, but the highest Ulva biomass was associated with the lowest DIN and anthropogenic N. Under luxuriant background nutrient conditions, variability in temperature and periods of emersion, rather than pH, light and salinity determined Ulva biomass. Two dominant species of Ulva displayed differing tolerances to temperature and desiccation which helped explain why Ulva prolifera dominates floating green-tides. Rather than trying to mitigate greentides only by reducing nutrient pollution, an earlier harvest of Pyropia in southern Jiangsu Province especially before temperatures increase greatly above 10°C during April, could reduce the biomass of U. prolifera disposed from rafts.Crown

“…Nutrient uptake ability is a significant factor in the competition among co-occurring species in the green tide. In the Ulva green tide that has recently occurred in the Yellow Sea, China, the dominant species Ulva prolifera O. F. Müller was superior in nitrogen uptake and stock ability compared to co-occurring Ulva linza Linnaeus (Luo et al, 2012). In our results, DIP was selected as a correlated variable on the RGR of U. pertusa cultured in the cages.…”

Since the late 1980's, a persistent green tide of floating Ulva without any clear seasonal fluctuation has occurred in Hiroshima Bay, Seto Inland Sea, Japan. We hypothesized that the persistence is due to the co-existence of Ulva species with different seasonal growth patterns, and monitored the seasonal composition and growth characteristics of the constituent Ulva within the green tide. Two morphological types of Ulva were identified, and one type, U. pertusa, was almost the sole constituent during winter and spring. The other type Ulva spp., which has marginal microscopic serrations on the thallus, was dominant during summer and autumn. Both Ulva showed the highest relative growth rate in early autumn, but growth of Ulva spp. was faster in summer than that of U. pertusa and inhibited in winter. U.pertusa had more eurythermal characteristics in which the growth rate remained relatively high in winter. Water temperature was the most correlated environmental variable for the seasonal growth of both Ulva types rather than light or nutrients, but more influential on Ulva spp. Recent increasing trend of ambient seawater temperature is considered to be favorable for the growth of both Ulva types and a causative factor of the green tide.
