| Event occurred before in this location: | Yes (Since 1986, with a break in 1991, G. Catenatum has been the responsible species for PSP at the Portuguese coastal zone. In 1999 and 1994, all the coast was affected, beguinning in the South and spreading to the North. In 1995 the main affected area was the Algarve coast, in an extensive way, covering all the litoral, sea Lagoons and Estuaries. This year only very restricted areas and only some bivalve species at Mondêgo Estuary, Algarve coast and Formosa Lagoon were affected for a short time.) | |
