%X A study was conducted with the aim of showing which environmental conditions promote an increase in #Dinophysis$ cells in a land-locked embayment with shellfish installations. From may 1989 to september 1991, vertical profiles were taken of temperature, salinity, nutrients and chlorophyll-a, and counts of phytoplankton species composition were made during late spring and summer. In the strait separating this area from the open sea, residual tital currents are from offshore to nearshore. Significant thermocline ... and stable stratification of the water column were required for #Dinophysis$ to exceed 1000 cell L-1. #Dinophysis$ spp. were more abundant in the "thermocline layer", scarce below this layer and absent near the bottom. These stratified conditions occurred first in the open sea. Denser #Dinophysis$ populations were then carried through the strait from offshore to nearshore waters by tidal currents.
