Abstract (EN):
The phytoplankton community of the international section of river Minho was studied during the spring-summer periods 1989 and 1999. Samples were collected not on a regular basis from S. Gregório (mostly in the upstream international section) to Caminha, at the Minho estuary. According to our results, eutrophication seems to decrease from upstream to downstream sites. The occurrence of cyanobacteria blooms, especially of Microcystis aeruginosa, in the Minho River mainly in August suggests that they may be formed in Spanish reservoirs and then float downstream into the studied section. These data clearly show that the monitoring of cyanobacteria in Minho River is important. Data can he used to prevent human health risks, as this water is used for drinking, recreation and shellfish harvest. © Asociación Española de Limnología.
