Evaluation of the development of ecological potential in selected canyon-shaped reservoirs with respect to their fish communities.
Říha, Milan; Blabolil, Petr; Soukalová, Kateřina; Peterka, Jiří
2021 - Czech
The report assesses the development of the ecological quality index with respect to a fish community in selected reservoirs. The assessment was carried out for reservoirs where fish stocking was sampled in different years and thus it was possible to assess the temporal evolution of this index. The report describes the calculation of the index, the trends in the index for each reservoir and the cause of changes in the index. Zpráva hodnotí vývoj indexu ekologické kvality z hlediska rybí obsádky ve vybraných údolních nádržích. Hodnocení bylo provedeno u nádrží, ve kterých bylo vzorkování rybí obsádky provedeno v různých letech a bylo tak možné hodnotit časový vývoj tohoto indexu. Zpráva popisuje kalkulaci indexu, trendy indexu u jednotlivých nádrží a příčinu jeho změn.

Final report from the mapping of the weatherfish (Misgurnus fossilis) in the NPP Žehuňský rybník and its surroundings.
Muška, Milan; Blabolil, Petr; Draštík, Vladislav; Kolařík, Tomáš
2021 - Czech
The report evaluates the results of a survey focused on weatherfish in the NPP Žehuňský rybník and the surrounding area. During the survey, a large population of weatherfish was found in the tributary part of the pond and the adjacent pool. This finding is essential for future revitalization planning and also significantly expands current knowledge of species distribution. Based on the results of the survey, the local population is one of the most important in the Central Bohemian Region. Zpráva hodnotí výsledku průzkumu zaměřeného na piskoře pruhovaného v NPP Žehuňský rybník a blízkém okolí. V průběhu průzkumu byla zjištěna početná populace piskoře v přítokové části rybníku a přilehlé tůni. Toto zjištění je zásadní pro plánování revitalizačních prací v budoucnu a také významně rozšiřuje aktuální znalost rozšíření druhu. Místní populace patří na základě výsledků průzkumu mezi nejvýznamnější ve Středočeském kraji.
