Resumen
En ésta investigación se realizó un análisis retrospectivo de la información existente sobre mareas rojas en el área costera e insular del Ecuador comprendidos entre 1968 y 2009, con el objetivo de liberar áreas y épocas de mayor concurrencia, als especies causantes de estos eventos y los registros de mortalidad de organismos. Los resultados evidenciaron 131 eventos de marea roja. Los años de mayor ocurrencia fueron 1985, 2001 y 2003. No todas las mareas rojas fueron causadas por las corrientes El Niño o La Niña. Se identificaron 37 especies causantes de mareas rojas de las cuales solo 26 eventos se relacionaron con mortalidad de organismos. Se propuso crear estrategias en el manejo de prevención, control y vigilancia a futuro de mareas rojas y sus impactos.
In this research we conducted a retrospective analysis of existing information on red tides in coastal areas and islands of Ecuador between 1968 and 2009, with the aim to liberate areas and times of high competition, als species causing these events and records mortality of organisms. The results showed 131 red tide events. The peak years were 1985 occurrence, 2001 and 2003. Not all red tides were caused by the current El Niño or La Niña. Identified 37 species causing red tides of which only 26 events were associated with mortality of organisms. He proposed creating management strategies for prevention, control and monitoring of red tides future and its impacts
