Permanently submerged mixed fucoids on rock in lagoons. Laminaria saccharina absent, possibly due to the low salinity conditions. The main species are Fucus vesiculosus and Fucus serratus, with Chorda filum and a variety of green seaweeds. Patches of dense Cladophora rupestris may occur on vertical rock faces.
