Forecast of red tides off the Galician coast

In Spain, mussels comprise around 90% of the total aquaculture production. Spanish mussel culture takes place almost exclusively in Galicia. The high productivity of the Galician coasts is a consequence of its western oceanic bound together with the seasonal northerly winds, generating strong upwelling of rich nutrient cold waters from May to September. When winds change to a southward direction, it results in a downwelling phenomenon which difficult the water renewal along the Galician Rias, contributing to the appearing of toxic blooms.
