Report on the survey of behavior and biomanipulation function of Europaen catfish population in Římov Reservoir in 2017
Říha, Milan ; Vejřík, Lukáš ; Peterka, Jiří ; Kubečka, Jan
Report summarizes our research of behavior and movement of wels catfish (Silurus glanis) in the Římov reservoir in years 2017-2018. Data about behavior and distribution were collected using a positioning telemetry system.
Report on the status of the burbot populations in the Karhov, Lučina, Nýrsko and Zhejral reservoirs and Obecník Pond in 2016
Blabolil, Petr ; Jůza, Tomáš ; Matěna, Josef ; Muška, Milan ; Peterka, Jiří ; Říha, Milan ; Vejřík, Lukáš
The aim of the study was to monitor the burbot populations in four reservoirs and in a pond with previous stocking. The monitoring was carried out during the spring season 2016 and, in the case of the Nýrsko Reservoir, during winter and summer as well. The combination of harmless methods (traps of two types, visual survay, electrofishing, hydroacoustic), a method simulating fishing pressure (long-lines) and a fix-frame trawl were used to detect burbot. A novel monitoring scheme was developet and validated and burbot populatin characteristics described.
Comparison of Prices for External Works on a Land Parcel in a Functional Unit with a Family House Determined via the Cost Method and in a Simplified Manner at a Chosen Location in Brno
Říha, Milan ; Ruberová, Marie (referee) ; Superatová, Alena (advisor)
The aim of the thesis is to assess the influence of the exterior finish works on the total price of a house. The total price of the house consists of the interior price valuated by the cost method and the price of the exterior finishes which were valuated with the help of two methods: the cost method and the simplified method based on the Property Valuation Act. The valuation also covers several periods of time: a new building and 11-, 25-, 50-, 75- and 100-years-old buildings. The thesis focuses on the lifetime of individual parts of the exterior finishes—especially the time after which it is necessary to replace or reconstruct a part. A significant focus was placed on the percents listed in the Act and their correspondence to the actual state. The thesis also deals with the various methods of valuation and their appropriateness in each case. It also mentions the influence of other factors on the price of an estate (the use of different exterior finishes, or a selection of a building location) but these factors were not examined in detail.

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.
Complex survey of fish community of the Švihov – Želivka valley reservoir in 2014.
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.
