Résumé :	During research on the phytoplankton in the Lagoon of Venice, monthly samplings were carried out from April 1988 to March 198. Samples were collected from four stations in the northern and southern basins of the lagoon during the spring tides (flood and ebb tide). Moreover some environmental parameters (transparency, temperature, salinity, dissolved oxygen and pH) were measured to point out ecological differences between the stations. Taxonomical identification and quantitative analyses of the planktonic microalgae were carried out. The planktonic microflora was composed by 261 taxa. Diatoms were prevalent and only Skeletonema costatum showed sometimes the higher values. Microflagellates, which are a heterogeneous group, were also abundant and widespread. Dinophyceae, Cyanophyceae, Euglenophyceae and Chlorophyceae showed low density values; in the southern basin, in January, Dictyocha speculum (Dictyochophyceae) registered very high cell density values. On the other hand, in the southern sampling stations, phytoplanktonic concentrations were higher than in the northern ones.
