Management plan of small water supply reservoirs of Landštejn type
Halačka, Karel ; Adámek, Zdeněk ; Jurajda, Pavel ; Mareš, J. ; Kopp, R. ; Grmela, J.
The aim of the methodology is to provide managers and users of small water reservoirs Landštejn type with methodological tools for optimization of the water quality monitoring based on the current level of knowledge and research. Furthermore, provides a design of a methodology for fish community monitoring and optimization of treatments to reduce unwanted fish species and strengthen the status of suitable fish species with the aim of achieving the topdown effect and maintaining or improving water quality in these water reservoirs. The presented methodology summarizes the findings obtained during the monitoring and evaluation of selected parameters of water quality, planktonic and fish communities in water supply reservoirs Landštejn in recent years. It also contains an evaluation of applied treatments, focused mainly on fish stock. Unwanted fish species were caught and the predatory fish were stocked with the aim of optimizing the fish community composition and positively influencing the quality of the water in the reservoirs. The methodology contains recommendations for monitoring of the water quality in the reservoir, including monitoring of planktonic communities, monitoring of fish and recommended manipulation with fish stock. The methodology provides guidance and information for optimization of monitoring and treatments for small water supply reservoirs of the Landštejn type.

An analysis of pond management in the Brno reservoir drainage area with respect to nutrient loading: a report on the project results
Adámek, Zdeněk ; Všetičková, Lucie
The impact of pond management upon the loading of Brno reservoir from its catchment area with 142 ponds and reservoirs > 1 ha (990 ha in total) was evaluated utilising the data from managing companies. The total annual phosphorus loading from pond management consists of 267,44 kg P from semi-intensive carp ponds, 10,22 kg from other ponds, 50,00 P from trout farms a 50,40 kg from storage pond faciltites.
An analysis of pond management in the Hracholusky reservoir drainage area with respect to nutrient loading
Adámek, Zdeněk ; Všetičková, Lucie
The impact of pond management upon the loading of Hracholusky reservoir from its catchment area with 193 ponds and reservoirs > 1 ha (1104 ha in total) was evaluated utilising the data from managing companies. The total annual phosphorus output from pond management was negative (-1396,88 kg) which means that phosphorus has been ponds retained in ponds.
Juvenile fish communities along selected profiles of the Odra basin
Jurajda, Pavel ; Jurajdová, Zdenka ; Mikl, Libor ; Šlapanský, Luděk
The aim of this report is to evaluate juvenile fish communities along specific profiles of the Odra River Basin as a basis for updating the Upper Odra River Basin Plan, according to the valid methodologies of the Ministry of the Environment.
A report about project DG16P02M032 NAKI II servis performance in 2018
Adámek, Zdeněk
Monitoring of the environment and zooplankton, zoobenthos and fish assemblages of ponds and waterbodies in Czech castle parks was performed. The results were used as a source data for proposals and evaluations of biomanipualtion and biomeliorative measures on selected reservoirs.
The genetic structure of brown trout populations at selected localities in the Krkonoše Mountains National Park
Jurajda, Pavel ; Bartáková, Veronika ; Jurajdová, Zdenka ; Mikl, Libor ; Bryjová, Anna
The aim of this study is to assess the genetic uniqueness of brown trout populations (Salmo trutta m. Fario) at selected localities in the Krkonoše Mountains National Park.
The standpoint on the importance of the Nové Mlýny Reservoir fish pass
Jurajda, Pavel
The subject of this contract is an assessment of the importance of the Nové Mlýny dam fish pass on the River Dyje as regards its importance for the fish community.
Ichthyological and hydrobiological survey of the Domovina and Mlýnský brook backwaters at Olomouc
Jurajda, Pavel ; Adámek, Zdeněk ; Všetičková, Lucie ; Jurajdová, Zdenka ; Šlapanský, Luděk
The subject of this contract is to assess fish community and zoobenthos status in the Domovina and Mlýnský brook backwaters in connection with the planned reconstruction of the Šantovka weir (Mlýnský brook).
