A recent study carried out by Epagri and IFSC analyzed the data generated by the toxin-producing algal blooms
monitoring state program between 2007 and 2019. It correlated these with data generated by meteorological models and satellite sensors to generate information to understand these events. The study showed that the genus Dinophysis is the group of toxin-producing microalgae that blooms most in SC and that diarrhoeic toxins are the most common. The study also shows that Dinophysis blooms can occur during all months of the year, but tend to be concentrated in the autumn and winter months and are related to the meteorological conditions observed during that period. Another important information is that Dinophysis blooms do not tend to coincide with non-toxic microalgae blooms and that chlorophyll estimates based on
satellites are not a good indicator of the occurrence of these events in Santa Catarina.
