Ogosta Field Trip

In the period 18-28 September 2010, a field survey in the Ogosta River basin was carried out. It included seasonal sampling in the Ogosta Reservoir, as well as in the Ogosta River upstream and downstream of the reservoir. To study the distribution and abundance of Dreissena populations (WP1) and their impact on the aquatic ecosystems (WP3), the following samples were collected at 5 sites in the Ogosta Reservoir: water chemistry, bacterioplankton, phytoplankton, phytoplankton pigments, zooplankton, epilithic diatoms, benthic macroinvertebrates and fish.
We are grateful to the National Agency of Fishery and Aquaculture – Montana for their help during the field sampling.
