Skadar lake is the largest lake in th Balkan Peninsula. The total area is 5500 m². Terretorialy the lake belong to Montenegro and to Albania. Both the sides of lake is a big development of acquatic vegetation, including a large variety of habitats and biological communities. The most important associations are Potameto-Najadetum, Trapetum natantis, Myriophyllo-Nupharetum, Nymphoideum peltata. These associations include lake shore macrophytes Najas, Vallisneria, Potamogeton, floating macrophytes Nuphar luteum, Trapa natans, Numphaea alba. Emersed water macrophytes are developed on both sides of lake predominantly in the eastern part of lake (Kamice Shegan) which go as far as 3 meter deep such Ceratophyllum, Najas marina, Najas minor, Vallisneria.Trapeum natantisi is largely widespread community in the Skadar lake. Waternuts develops wide population and communities in the inner and deeper part of the floating macrophyta zones. Plant samples were collected on the both sides of the lake. For Trapa natans specie is determined the content of photosynthetic pigments, chlorophyll a, chlorophyll b and carotenoids. Photosynthetic pigments were extracted with 80% acetone and their concentrations are expressed in mg/g dry absolutely leaf .Their measurement is made in the bands f 663, 645.470, of spectriphotometer. Trapa natans was found in the eastern shore and in western shore of Skadar lake. The highest values of chlorophyll a an b in the species Trapa natans was found in September 2014.
