| A red tide of Lingulodinium polyedrum occured along the moroccan atlantic coast in july 1999. Observed in the beginning of the month in the Kenitra area, it spreads with the coastal drift as far as the south of safi, passing on its way upon a sanitary monitored area. This area which is submitted to an all year round bimonthly monitoring analysis of phytoplankton, contains significant natural beds of oysters, clams and mussels, as well as shellfish farms in Oualidia and Sidi Moussa lagoons. However, during this period of bloom, there was weekly monitoring of hydrologic and climatic data associated with phytoplankton analysis to identify the causes of this bloom. This bloom occured in 17-18degreesC surface waters, temperatures which are favourable to... |

| In this study, an original use of immersed microfiltration membranes (mean pore size equal to 0.2 mu m) is investigated for the total removal of toxic dinoflagellates from seawater. Using a membrane autopsy and fouling model approach and the use of fouling indexes (called Pore Blocking Index, Pore Constriction Index and Cake Filtration Index), three dinoflagellate suspensions (Heterocapsa triquetra, Alexandrium minutum and Prorocentrum lima) have been microfiltered in order to study the influence of micro-algal species and its concentrations (1,000 and 30,000 cells/mL) on filtration yield and membrane fouling mechanisms. Results showed that all micro-algae have been retained after 180 min of microfiltration. At 30,000 cells/mL, permeate fluxes declined... |

| It was studied on the choice of potential area for red tide occurrence from oceanographic factors. Oceanographic factors of favorable marine environmental conditions for the red tide formation included warm water temperature, low salinity, high suspended solid, low phosphorus, low nitrogen. It was founded the potential areas for red tide occurrence in August 2000 by GIS conception: Yeosu~Dolsan coast, Gamak bay, Namhae coast, Marado coast, Goheung coast, Deukryang bay, respectively |
