Harmful Algal Blooms (HABs) are phytoplankton blooms which have detrimental environmental and socioeconomic impacts. The Mediterranean Sea is of special concern since it has an enormously rich native biodiversity, though it is also the world’s most invaded marine ecosystem and is considered at very high risk of future invasions. The aim of this study is to explore the origins, establishment, environmental and socioeconomic impacts of HABs caused by nonnative algal species in the Mediterranean Sea. Based on this, it is also discussed whether HABs form an increasing threat in the basin, and what could possibly be done to prevent or minimize their impacts. The increasing rate of their introduction and the harmful impacts that they have on the environment, economy and human health makes it important to have accurate knowledge about HABs. Anthropogenic activities and climate change are considered the main contributors of alien invasions but also the main enablers of HAB events. Mediterranean HABs are adequately studied, but there are no studies purposefully concerning invasive microalgae species in the basin. In the present thesis, 20 species have been identified, and an attempt has been made to collect their introduction information, as well as known or suspected impacts. Since HAB alien events are likely increasing in the Mediterranean, collecting more information and ameliorating already existing databases and reports should become a priority in order to update current legislations and monitoring techniques.
