Floraciones algales nocivas en la bahía de Santiago de Cuba
Santiago de Cuba bay is an ecosystem eutrophic and vulnerable to FANs events. This work preset the results of monitoring during three year in eight stations located in the less polluted area of the bay, leading to the determination of the possible seasonal distribution and FANs frequency. 117 Phytoplankton species were identifying, which belong to 5 divisions; 28% of these species are reported as potentially toxic and/ or noxious. This zone of the bay classifies as politrophic, heterogeneous and dynamics. It highlights the cysts presence, as well as the occurrence of unialgal "blooms" of Gymnodinium catenatum and Cochlodinium polykrikoides, indicating the presence in the ecosystem of favorable conditions to HABs occurrence with negative impact on the ecosystem. There are some reports of massive mortalities of fish and blue crabs. All of it indicates that it becomes necessary to maintain the systematic surveillance in the bay, considering the community participation, and the coordination and instruction to decisions makers, with the objective of mitigating the risks and HABs impacts.
