The Gulf of Nicoya, an estuary on the pacific coast of Costa Rica, extends 80 Km, from the Tempisque River to the Pacific, with a maximum width of 50 Km at the mouth, and an area of 1550 Km2. Hydrography of the Gulf depends on rainfall and wind patterns. Nutrient advection into the Gulf, during the rainy season (May to November) carried by the Grande de Tárcoles and Tempisque Rivers [1], have a stimulant effect on phytoplankton abundance [1-3] and composition [4]. The Gulf of Nicoya is a very important fishing ground on the Pacific coast. About 800 families make their living from shellfish extraction in the Gulf. The Gulf waters and the surrounding mangroves are also important nursery areas for larvae and juveniles of commerciallyimportant species, and many beach areas have intense tourist activity. Therefore, harmful algal blooms pose a threat to the Gulf resources, fisheries, consumer health, the incipient aquaculture activity and tourism.
