Hydroacoustic assessment of the fish stock in Lake Balaton in 2017
Tušer, Michal ; Muška, Milan
This report describes a study of open-water fish assemblage in Lake Balaton, Hungary, in 2017. The lake was acoustically surveyed using two horizontally-oriented 120 kHz transducers. The observed fish stock was assessed on the basis of fish sizes, abundance, biomass, and spatial distribution in the lake.
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.
Ichthyological surveys of the Nýrsko and Karhov reservoirs and investigations of abundance, age composition and spawning dynamics of asp population in the Želivka Reservoir in 2015.
Vašek, Mojmír ; Soukalová, Kateřina ; Kočvara, Luboš ; Blabolil, Petr ; Baran, Roman ; Frouzová, Jaroslava ; Koliada, Ievgen ; Muška, Milan ; Šmejkal, Marek ; Draštík, Vladislav ; Kolařík, T. ; Prachař, Zdeněk ; Sajdlová, Zuzana ; Vebrová, L. ; Vejřík, Lukáš ; Kubečka, Jan
The species composition and the relative abundance and biomass of fish communities in the Nýrsko and Karhov reservoirs were evaluated by means of standardised multimesh gillnets. The spawning stock of asp in the Želivka Reservoir was individually marked using PIT tags and the density and behaviour of tagged fish at the main spawning grounds were examined through the whole spawning season. The total number of reproducing individuals in the asp population was estimated. The sex-specific length and weight growth rates of adult asp in the Želivka Reservoir were also calculated. \n\n
The report on mapping of spined loach occurrence in national nature area Bohdanečský pond, quarry Hostěradice and selected nearby localities.
Blabolil, Petr ; Muška, Milan ; Bartoň, Daniel ; Kočvara, Luboš ; Matěna, Josef ; Soukalová, Kateřina ; Vejříková, Ivana
The aim of the ichthyological survey was to assess the status of spined loach (Cobitis elongatoides) in two distinct populations together with description of the environment.\n\n
A new tool for improvement the quality of water ecosystems

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.
Monitoring of fish populations in Vltava River, quantification of fish migration from reservoir into Vltava River.
Muška, Milan ; Tušer, Michal
The aim of the study was to quantify fish migration activities between Lipno Reservoir body and Vltava River with special emphasis put on description of the dynamics of migratory processes, estimation of abundance of migrating fish and evaluation of the influence of migrants from reservoir on autochthonous river fish community.
Hydroacoustic assessment of the fish stock in Lake Balaton in 2014
Tušer, Michal ; Muška, Milan
The objective of this project was to survey fish assemblage in Lake Balaton using 120 kHz acoustics to estimate fish quantity in open water at night. In addition, the results from this work could further help answer what a proportion of Asian carps might occupy the waters of Lake Balaton based on the resultant size distribution of observed targets.
Ichthyological survey of fish communities of Láz, Pilská and Obecnice reservoirs in 2014.
Muška, Milan ; Vašek, Mojmír ; Blabolil, Petr ; Kočvara, Luboš ; Soukalová, Kateřina
The aim of the complex ichthyological survey of Láz, Pilská and Obecnice reservoirs in 2014 was the description of fish community composition and succession with the emphasis put on the abundance and biomass estimates of single species.
