Abstract: This research was done in order to determine the amount of certain nutrients in algae in the wetland areas of Van Province. Ten sampling stations with different characteristics, including natural lakes, rivers and reeds were chosen. In this study, we have identified Spirogyra spp., Microspora spp. and some mixed diatom groups (Nitzschia spp. taxons), Cladophora fracta, Ulothrix zonata, Cladophora glomerata, Hydrodictyon reticulatum, Mougetia spp. and Zygnema spp. in the selected locations. In the species of algae which were determined at the stations in this research, the rates of the lowest and highest values for Dry Matter (DM), Crude Protein (CP), Ether Extract (EE), Crude Fibre (CF), ash and Nitrogen Free Extract (NFE) were determined respectively as 93.20-99.36, 3.10-20.27, 0.04-1.03, 3.77-28.95, 29.20-87.76, 3.59-38.82%. The lowest and highest amounts in the samples of the stations for Calcium (Ca), Phosphorus (P), Nitrogen (N), potassium (K), sodium (Na), Magnesium (Mg), iron (Fe), Manganese (Mn), Copper (Cu) and Zinc (Zn) were determined, respectively as 29.16-779.73, 0.21-9.64, 0.42-3.24, 5.12-125.97, 2.92-78.88, 13.73-29.77, 4.96-28.33, 0.07-2.60, 0.01-0.05 and 0.01-0.17 mg/kg.
