Effects of the decomposing green macroalga Ulva (Enteromorpha) prolifera on the growth of four red-tide species

In situ detrimental impacts of Prorocentrum donghaiense blooms on zooplankton in the East China Sea

“…High biomass blooms are always associated with poor water quality due to algal metabolic activities. Decomposition and respiration of algal cells always leads to the depletion of oxygen, production of ammonia and other nitrogenous by-products, and/or in the formation of toxic sulfides (Trainer et al, 2010;Wang et al, 2012;Branch et al, 2013), which are related to the mass mortalities of marine organisms caused by algal blooms (Morrison et al, 1991;Forbes and Borstad, 1990;Matthews and Pitcher, 1996;Cockcroft, 2001;Pitcher and Weeks, 2006;Pitcher et al, 2008). In this research, the levels of oxygen at decay-bloom areas did not differ significantly from those at the other stations (Xiao-yong Shi, unpublished data).…”

Validation of MODIS-based monitoring for a green tide in the Yellow Sea with the aid of unmanned aerial vehicle

“…3,4 In addition, masses of Ulva also impact the coastal tourism industry, thus significantly influencing the coastal economy, ecological environment, and aquaculture industry. [5][6][7][8][9] Due to the extensive spatial distribution of the green tide, traditional monitoring is inadequate for conducting routine and real-time monitoring. Due to its timeliness, economic efficiency, and ability to survey large areas simultaneously, 10,11 satellite remote sensing instruments, such as the sea-viewing wide field-of-view sensor, medium resolution imaging spectrometer, moderate resolution imaging spectroradiometer (MODIS), hyperspectral, Landsat multispectral scanner, thematic mapper, and enhanced thematic mapper, have been highly utilized in mapping floating cyanobacterial scum and seagrasses that have the similar characteristics as Ulva.…”

Development of a fluorescence in situ hybridization (FISH) method for rapid detection of Ulva prolifera

“…Massive, free-floating green tides, for example, first emerged in the Yellow Sea (YS) in the summer of 2007 and became a recurrent phenomenon after that. Green tides significantly collapsed tourism, aquaculture industry and coastal ecosystems (Wang et al, , 2012. In 2008, the large-scale green tide posed a significant threat to the Olympic sailing event in Qingdao and resulted in a huge economic loss.…”
