Abstract
    The seasonal and spatial variability of rocky intertidal phytobenthic communities, with a particular emphasis on the green macroalga Cladophora spp., were examined in Liopetri Bay, Cyprus, along with changes in nutrient inputs from a fish-hatchery. Increased nutrient inputs, and particularly nitrates, in the effluents of the hatchery resulted in significant changes in the composition and density of intertidal rocky phyto-communities and particularly, in the stimulation of the overgrowth of the macroalgae Ulva spp. and Cladophora spp. in the adjacent area of the hatchery. Cladophora spp. then expanded in the Bay most likely by wind-driven currents and waves, while it continued its proliferation presumably by other nutrient sources such as the discharge of the nitrates-rich groundwater horizon, domestic effluents and the open sea fish cages. Based on the data on the situation of Cladophora spp. along the broader coastline of Cyprus, it seemed that Cladophora spp. appears every year in "normal" growth around most of the coasts of Cyprus; in the presence of excess nutrient inputs combined with high temperatures it causes eutrophication events.
