[email protected] The composition and distribution of the main planktonic halophilic microorganisms were studied in 12 ponds of different salinity levels, ranging from 38 to 328, in the saltern of Sousse, Tunisia, in relation to environmental factors. Nutrient concentrations increased with decreasing salinity in the ponds. Phytoplankton, ciliate and zooplankton communities were very diverse and varied spatially in relation to salinity in the ponds and to nutrient availability. Phytoplankton were dominated by diatoms, followed by dinoflagellates, in primary ponds where salinities were 12 mg l–1) in Ponds EM to SO1 and low (
