The Czech multimetric fish based index (CZ-FBI) was developed recently. The aim of CZ-FBI is to assess the ecological potential of heavily modified and artificial water bodies and to detect ecosystems, particularly their specific components, in unsatisfactory conditions. This article describes steps of CZ-FBI development. Since the philosophy used, particular events presenting the results, to recent stage. CZ-FBI is a part of certified methodology of the Ministry of the Environment of the Czech Republic and the comparison with other assessment methodologies within a geographical intercalibration group is in process.

Matěna, Josef ; Říha, Milan ; Soukalová, Kateřina ; Kočvara, Luboš ; Kubečka, Jan
The aim of the complex ichthyological survey of the Švihov – Želivka valley reservoir in 2014 was the description of fish community composition and evaluation of its succession and biomanipulative function.
Fish stock assessment of the Petrusplaat Reservoir in 2014
Říha, Milan ; Jůza, Tomáš ; Vašek, Mojmír ; Soukalová, Kateřina ; Kočvara, Luboš
The aim of the complex ichthyological survey of Petrusplaat Reservoir in 2014 was the description of fish community composition and succession with the emphasis put on the abundance and biomass estimates. All important littoral/benthic and pelagic habitats were sampled using the well-established methods (benthic and pelagic gillnets, shore seining and pelagic fry trawling) aiming particularly on the improvement of abundance and biomass estimates of large fish.
Fish stock assessment of the Honderd en Dertig Reservoir in 2014

Borovec, Jakub ; Hejzlar, Josef ; Znachor, Petr ; Nedoma, Jiří ; Čtvrtlíková, Martina ; Blabolil, Petr ; Říha, Milan ; Kubečka, Jan ; Ricard, Daniel ; Matěna, Josef
Methodology for the assessment of the ecological potential of heavily modified and artificial water bodies was developed, including water body typology. The selection of indicator metrics was based on statistical analyses of the sensitivity of each of the indicators towards the most significant stressor – eutrophication. According to these results, biological communities and their indicators were selected to comply with the requirements set forth in the Water Framework Directive (2000/60/EC).
Report on hydrobiological and ichthyological monitoring of Římov reservoir in 2012
Říha, Milan ; Kubečka, Jan ; Seďa, Jaromír ; Jůza, Tomáš ; Soukalová, Kateřina ; Znachor, Petr
The report summarizes results of regular complex monitoring of limnological components of the ecosystem of Římov reservoir achieved in 2012, and suggests recommendations for further monitoring of the water body.

Methodology for the assessment of the ecological potential of heavily modified and artificial water bodies of the lacustrine type was developer, including also typology of water bodies. The selection of indicator metrics was based on statistical analyses of the sensitivity of each of the indicators towards the most significant stressor – eutrophication. According to these results, biological communities and their indicators were selected to comply with the requirements of the Water Framework Directive (2000/60/EC).
