Abstract The dynamics are presented of the main primary producers in seven representative Danube Delta lakes. Generally, the primary productivity developed from the macrophyte-epiphyte complex towards the phytoplankton. Species changes occurred in the two main compartments with increasing relative abundance of colonial blue-green algae in the phytoplankton and in submerged macrophytes of species with a vertical growth strategy. These changes are linked to accelerated eutrophication of the lakes, with increased phosphorus loading and a reduction in N:P ratio.
