The aim of the ichthyological survey was to assess the status of reproductively active population of asp (Leuciscus aspius) in the SCI (site of community importance) Želivka (Švihov Reservoir) and spined loach (Cobitis elongatoides) in the SCI Nová Říše (Nová Říše Reservoir).
Investigation of Cladophora sp. distribution in the Brno reservoir, conducted under the project “The implementation of management measures at the Brno reservoir, phase II 2013-2017
Borovec, Jakub ; Matějíčková, Ivana ; Vejřík, Lukáš ; Kočvara, Luboš ; Hauer, T.
The occurrence of the green alga Cladophora and other macrophytes in the Brno reservoir was confirmed. The distribution of Cladophora stands was assessed as not dramatic, despite of the temporary occurrence of a mass of surface-floating filaments. This increase in buoyancy of the Cladophora colonies was caused by excessive oxygen production in the co-growing algal species (Tetraspora sp.).
Research on reproductive biology of asp Leuciscus aspius and its sampling during 2008 and 2014 in Švihov reservoir
Vejřík, Lukáš ; Bouše, Eduard ; Matějíčková, Ivana ; Ricard, Daniel ; Kubečka, Jan
Based on electrofishing for asp in main tributaries of Švihov reservoir and subsequent tagging of captured fish, size and age composition of asp spawning stock together with the importance of primary and secondary tributaries for spawning and asp growth was evaluated in years 2013 and 2014. Survival of fish tagged in previous years 2008-2012 was estimated as well.
