Complex survey of the fish stock of Lake Most in 2020.
Peterka, Jiří
2021 - Czech
Aim of the complex ichthyological survey of Lake Most 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 lake management. Summarization of achieved results and recommendations for further monitoring are included in the presented report. Cílem ichtyologického průzkumu jezera Most 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 jezera. Sumarizace dosažených výsledků a návrh doporučení pro další sledování jsou obsahem předkládané zprávy.

2021 - Czech
The limnological measurement and research of periphyton and aquatic macrophytes were conducted in the framework of 'Strategy AV 21, post-mining landscape restoration' in 2020. Despite the good ecological potential in Lakes Milada and Most, there are several indications of possible future deterioration of water quality (e.g., the occurrence of subsurface cyanobacterial maxima in Lake Most, excessive growth of periphyton mats in both lakes, strong bottom anoxia in Lake Milada). Zpráva shrnuje výsledky limnologických měření a výzkumu perifytonu a vodních makrofyt probíhajícího v rámci programu Strategie AV 21, Záchrana a obnova krajiny v roce 2020. Ačkoli jakost vody v jezera Most a Milada odpovídá dobrému ekologickému potenciálu, zaznamenali jsme náznaky možného budoucího zhoršení (např. výskyt podpovrchových sinicových maxim v jezeře Most, nadměrný rozvoj nárostových řas v obou jezerech, výskyt anoxie u dna v jezeře Milada).
