Sažetak
Vrana Lake near Biograd na Moru is a karst field filled with water and is the largest natural lake in Croatia, connected to the sea by a channel. It was declared as a Nature park in 1999, mostly because of the ornithological reserve in its area. Zooplankton plays a significant role in lake ecosystems, especially in determining the ecological status of lakes. The goals of the research were: (i) to determine the abundance, biomass and diversity of zooplankton ; (ii) to study the impact of biotic and abiotic factors on zooplankton dynamics ; (iii) to study the impact of fish predation on zooplankton dynamics. In the two years period (2018 and 2019), zooplankton samples were taken at three longitudinal stations. In order to analyze the dynamics of zooplankton several abiotic and biotic factors were observed: temperature, oxygen, conductivity, salinity, ph, transparency, nutrients, chlorophyll a, and fish predation. The research revealed a significant influence of temperature, salinity, dissolved oxygen, transparency as well as significant influence of ichthyofauna on the structure and dynamics of zooplankton. This study of planktonic zooplankton will provide insight into the trophic state of the lake, which will enable the determination of guidelines for further management of Vrana Lake and protection of this valuable and important habitat.
