Complex survey of the fish stock of Lake Chabařovice in 2020.
Peterka, Jiří
Aim of the complex ichthyological survey of Lake Chabařovice was to map the current state and succession of lake’s fish stock with particular emphasis put on abundance and biomass estimates of all fish species, evaluation of possible risks to the further development of the fish stock and recommendations for the lake management. Summarization of achieved results and recommendations for further monitoring are included in the presented report.

Hydrobiological monitoring of Medard lake in 2019
Hejzlar, Josef ; Nedoma, Jiří ; Znachor, Petr ; Seďa, Jaromír ; Peterka, Jiří
Presented report summarizes the results of hydrobiological monitoring of Medard Lake in 2019 and recommends further monitoring actions. The year 2019 was the second year after the lake was filled, when no more water from the Ohře River was filled and only small tributaries from the small river basin flowed into the lake. Thus, the ecosystem of the lake has reached a final state in terms of hydrological regime and nutrient load, characterized by very low water exchange, low trophic levels with low productivity of planktonic communities, development of submerged macrovegetation in coastal zones and specific seasonal changes in chemistry and biological parameters.

Hydrobiological monitoring of Medard Lake in 2017
Hejzlar, Josef ; Nedoma, Jiří ; Znachor, Petr ; Seďa, Jaromír ; Peterka, Jiří
The report summarizes the results of hydrobiological monitoring of Medard Lake 2017 and contains recommendations for further research activities. At the beginning of 2017, the lake was almost full, and at the end of March the last 30 cm water column was filled from the Ohře river. The ecosystem of the lake has reached its final nutrient load, which will be characterized by low levels of carrying capacity with low productivity planktonic and fish communities and specific seasonal changes in chemistry and biological parameters.
