Hydrobiological monitoring of Lake Medard in 2020.
Peterka, Jiří; Hejzlar, Josef; Nedoma, Jiří; Znachor, Petr; Seďa, Jaromír
2021 - Czech
The aim of this report is to summarize the results achieved in 2020 and make recommendations for further monitoring. The year 2020 was the third year after the full filling of the lake. The lake ecosystem has reached a final state in terms of hydrological regime and nutrient load, which is characterized by very low water turnover, low trophic state with low productivity of planktonic communities, development of submerged macrovegetation in littoral areas and specific seasonal changes in chemistry and biological parameters. However, the aquatic ecosystem is far from being stabilized and the biological communities of the littoral and the open water areas, including the fish community, are still changing considerably from year to year. Cílem předkládané zprávy je sumarizace dosažených výsledků za rok 2020 a doporučení pro další sledování. Rok 2020 byl třetím rokem po úplném naplnění jezera, kdy se již žádná voda z Ohře nenapouštěla. Do jezera přitékaly pouze drobné přítoky z jejího povodí a zároveň voda z jezera odtékala průsaky, které jsou zřejmě drénovány do blízkých toků, Ohře a Svatavy. Ekosystém jezera se dostal z hlediska hydrologického režimu a živinového zatížení do konečného stavu, pro který je typická velmi malá obměna vody, nízká úroveň úživnosti s nízkou produktivitou planktonních společenstev, rozvoj ponořené makrovegetace v příbřežních zónách a specifické sezónní změny chemismu i biologických parametrů. Vodní ekosystém však ještě zdaleka není stabilizován a biologická společenstva příbřežní zóny (litorál) i volné vody (pelagiál), včetně společenstva ryb, se dosud rok od roku značně mění.

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.

2021 - Czech
Aim of the complex ichthyological survey of the Lučina Reservoir 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 reservoir management. Summarization of achieved results and recommendations for further monitoring are included in the presented report. Cílem ichtyologického průzkumu nádrže Lučina bylo zmapování stavu a vývoje rybí obsádky, přičemž důraz byl kladen zejména na odhad početnosti a biomasy jednotlivých druhů ryb, na odhad rizik dalšího vývoje rybí obsádky a doporučení dalšího obhospodařování nádrže. Sumarizace dosažených výsledků a návrh doporučení pro další sledování jsou obsahem předkládané zprávy.
