Trophic state of Albanian water ecosystem based on phytoplakton photo-synthetic pigments

EnData on the trophic state of some Albanian water bodies (the Adriatic lagoons of Vilun,Kune-Vain,Patog,Karavasta and Narta,and the ecosystem of Ohrid-Prespa)are resented.Evaluation of trophic state is based on chlorophyll acontent in water and distribution of photosynthetic pigments,monitored from March to October.The lagoons of the Adriatic coast have different trophic states.The lagoons of Vilun,Kune-Vain and Patok are oligotrophic,but the Karavasta and Narta lagoons are characterized by a higher trophic state,estimated as mesotrophic.Lake Ohrid is oligotrophic,whereas Lake Prespa is mesotrophic.Vertical profiles of Chl a content demonstrated different distribution in the Ohrid and Prespa lakes

Evaluation of the Trophic Level of Kune and Vain Lagoons in Albania, Using Phytoplankton as a Bioindicator

Concentration of chlorophyll is an adequate parameter for assessing the trophic state of lagoon ecosystems. Objectives of this study are: selection of a system of bioindicators to enable a good qualitative evaluation of the trophic state of the lagoons and their dynamics; evaluation of seasonal water quality variability and comparison between lagoons. The trophic state of the lagoons is analysed every month over the year. Water samples are retrieved at four different sites (exact coordinates) each month, sites that are representative of different water circulation systems at each lagoon. The trophic level in the respective lagoons is thus assessed through selection of an adequate system of bioindicators, in order to observe the oscillations of the amount of chlorophyll and therefore to determine the level of eutrophication. Based on the above parameters, the comparison of the trophic state in these two lagoons has shown that they have different trophic states
