Hydroacoustic assessment of the fish stock in Lake Balaton in 2017
Tušer, Michal; Muška, Milan
2018 - English
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. Keywords: biomass; abundance; open-water distribution Available at various institutes of the ASCR

Fish stock assessment of the Petrusplaat Reservoir in 2016, Fish stock assessment of the Honderd en Dertig Reservoir in 2016, Fish stock assessment of the De Gijster Reservoir in 2016
Jůza, Tomáš; Soukalová, Kateřina; Kočvara, Luboš; Prachař, Zdeněk
2017 - English
In 2016, the aim of the complex ichthyological surveys of Petrusplaat, Honderd en Dertig and De Gijster reservoirs 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 and ichthyoplankton trawling, benthic traps) aiming particularly on the improvement of abundance estimates of gobiid fry. Keywords: fish community composition; succession; biomanipulation Available at various institutes of the ASCR

2016 - English
The report (1) summarizes the results of the complex ichthyological survey of the Petrusplaat Reservoir in 2015. Species composition, abundances, biomasses and age composition of fish were investigated based on gillnets, seine nets, trap nets and trawl catches. Obtained results were also compared with data from previous surveys. The report (2) summarizes the results of the complex ichthyological survey of the Honderd en Dertig Reservoir in 2015. Species composition, abundances, biomasses and age composition of fish were investigated based on gillnets, seine nets, trap nets and trawl catches.

Hydroacoustic assessment of the fish stock in Lake Balaton in 2014
Tušer, Michal; Muška, Milan
2015 - English
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. Keywords: hydroacoustics; abundance; biomass; Asian carps Available at various institutes of the ASCR
