From September 2012 to July 2013 the phytoplankton community was studied from five sampling stations located along the longitudinal axis of the Sidi Moussa lagoon, situatied in the atlantic Moroccan coast. Seasonal and spatial patterns of distribution in relation to some hydrological parameters (temperature, salinity and nutrients) are also reported. The results obtained after quantification and identification of species of dinoflagellates during the study period showed a large variability in cell abundance and plankton blooms, the most important being those of the species to peridinium quinquecorne with 5.105 C/L and kryptoperidinium foliaceum arriving in concentrations above 107 C /l, this blooms were positively correlated physicochemical parameters.These two species, are identified for the first time in the Sidi moussa lagoon.
