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.
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.
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).
The impact evaluation of extreme precipitation-discharge events upon aqautic organisms: monitoring of macrozoobenthos response on extreme precipitation (discharge) events at the Němčický brook
Adámek, Zdeněk ; Všetičková, Lucie
No episodes of extreme high discharge rates on the Němčický brook appeared in 2018. Contrarily, zero discharge (drought) persisted for the most of growing season with fatal consequences.
Potrava dravých ryb vodárenských nádrží povodí Moravy
Mikl, Libor ; Adámek, Zdeněk ; Šlapanský, Luděk ; Všetičková, Lucie ; Jurajda, Pavel
Biomanipulace jsou považovány za jeden ze základních pilířů, kterými je možné ovlivnit jakost vod na vodárenských nádržích. Pro posouzení možností a účinnosti biomanipulačních opatření na vodárenských nádržích v povodí Moravy (Bojkovice, Ludkovice, Landštejn, Nová Říše a Hubenov) proběhly během jarních a letních měsíců v letech 2016 a 2017 kontrolní odlovy ryb (Jurajda et al. 2018). Ryby byly odlovovány s použitím elektrického agregátu a tenatních sítí. Na potravní analýzu bylo celkem odloveno 922 jedinců (dále ind.) dravých ryb: štika obecná (39 ind.), bolen dravý (24 ind.), okoun říční (805 ind.), candát obecný (43 ind.) a sumec velký (11 ind.).\nRybí složka v potravě dravých ryb studovaných vodárenských nádrží, tvořila celkem 75 % hmotnostního zastoupení z celkově přijaté potravy a dominovaly v ní především kaprovité ryby s 41 % hmotnostním zastoupením (plotice 15 %, perlín 12 %, cejn 8 %, ouklej 3 % a blíže neidentifikovatelné kaprovité ryby 2 %) a okounovité ryby s 20 % (okoun 15 %, candát 2 %, ježdík 1 % a blíže neidentifikovatelné okounovité ryby 1 %). Natrávené zbytky ryb, které nebylo možno zařadit do žádné vyšší taxonomické skupiny, tvořily 12 %. Druhou nejpočetnější složku potravy tvořili bezobratlí (24 %). Nezanedbatelnou část kořisti predátorů tvořily i samotné dravé druhy ryb 23 % (okoun 15 %, štika 4 %, candát 3 %, blíže neidentifikovatelné okounovité ryby 1 %). Kanibalismus se na složení potravy dravých druhů ryb podílel celkem 11 %, u okouna tvořil 15 %, u štiky a candáta shodně 13 %, zatímco u bolena a sumce nebyl zaznamenán.\nVýsledky potravních analýz spolu s monitoringem rybích společenstev studovaných nádrží, při němž byl zjištěn poměrně vysoký poměr dravých ku nedravým rybám (Jurajda et al. 2018) naznačují, že za současného stavu biomasy dravých ryb a vstupu nutrientů, mohou biomanipulační opatření sloužit maximálně jako prostředek k zakonzervování současného stavu jakosti vod na vodárenských nádržích, nikoliv jako opatření, které by mohlo významněji přispět ke zlepšení kvality surové vody.
