Description: Harmful Algal Blooms (FAN) o Red tides correspond to a proliferation in aquatic environments of microalgae that can cause the massive death of fish and other organisms, contaminating shellfish with toxins, and alter ecosystems, in ways that humans perceive them as harmful or harmful (GEOHAB, 2001). The impacts on Man and his activities, include shellfish poisoning, that can be fatal; massive deaths of marine organisms in the natural environment and in rearing or fattening systems; alterations of coastal habitats and, thus, disturbances in social and economic systems. In Chile, different toxins associated with Paralyzing Poison have been detected (VPM), Diarrheal Poison (VDM), and Amnesic Poison of Mollusks (TO YOU), which directly affect humans in addition to a number of other lipophilic toxins. Under this scenario, and considering the non-existence of antidotes for these toxins, the lack of technologies to control blooms in the environment or their removal from shellfish, the disturbances they cause in the social and economic systems, and the lack of models that allow predicting the appearance, duration and place of occurrence of these blooms, force to strengthen prevention and one of whose sources of information are monitoring programs.
The present symposium aims to share progress and experiences, views and challenges of the FAN problem among local researchers, with a view to updating the status of the studies developed at the national level, discuss new approaches and look for questions and common points for future global change scenarios, in which these events are expected to increase their frequency to intensity at the local and global level.
