Resumen

A bloom of Trichodesmium erythraeum with average densities of 3.5 x 106 trichomes L-1 was recorded in February 2014, in an extensive range of beaches on the northern coast of Bahia, Brazil. High water temperatures and rainfall, associated with wind frequency and intensity may have triggered the bloom, which lead to a strong odor and change in the color of the water, it obliged the authorities to shut down the affected beaches. These blooms negatively affected tourism and fishing, the main economic activities in the region, highlighting the importance of monitoring these events in the area.
