Shallow-water communities of opportunistic green marine macroalgae in eutrophicated areas are currently gaining an advantage over dominated by other groups macrophytes. Therefore, their classification, study composition and observation structural changes particular importance. One class (Ulvae intestinalis–Ulvetea linzae), one order intestinalis–Ulvetalia three alliances intestinalis–Ulvion linzae, Ulvae intestinalis– Ceramion virgati, rigidae–Gelidion spinosi) new associations macroalgal meso- polysaprobic sublittoral vegetation within the shelf Black, Azov Baltic Seas described for first time, using Braun-Blanquet approach. Principal components analysis revealed two main factors influencing floristic investigated communities: salinity nutrient enrichment with associated turbidity. The proposed classification algae should be used assessing dynamics state during eutrophication aquatic environment.
