The size selectivity of the main body of a sampling pelagic pair trawl in freshwater reservoirs during the night

The aim of this study was to test the selectivity of a trawl main body, especially for small fish, during night sampling. The tested trawl had a mesh...

Post-spawning dispersal of tributary spawning fish species to a reservoir system

This study investigated the post-spawning dispersal of seven species occurring in a tributary of the Římov Reservoir during the years 2000-2004....

The influence of diel period on fish assemblage in the unstructured littoral of reservoirs

Diel changes in littoral fish assemblage were studied in four reservoirs in the Czech Republic (Central Europe). The sampling was performed by beach...

Sinusoidal swimming in fishes: the role of season, density of large zooplankton, fish length, time of the day, weather condition and solar radiation

The sinusoidal swimming of fish, previously interpreted as foraging behaviour, was studied with respect to season, density of large zooplankton, fish...

The influence of the trawl mouth opening size and net colour on catch efficiency during sampling of early fish stages

The efficiency of different sized (0.5 m × 2 m, 1 m × 2 m, 2 m × 2 m, 4 m × 2 m) and coloured (black, white) ichthyoplankton trawl nets and the...

Fish activity as determined by gillnet catch: A comparison of two reservoirs of different turbidity

Fish activity was monitored analyzing the catches of gillnets exposed for short time intervals at night. Experiments were done in two Central...

Hydroacoustic estimates of fish stocks in temperate reservoirs: day or night surveys?

Day and night acoustic surveys were used to compare fish stock estimates at eight European reservoirs and one flooded mining pit. During both...

Long-term development of fish populations in the Rimov Reservoir

The inshore fish community of the Římov Reservoir in the Czech Republic was evaluated over 21 years using shore seining at night. The development...

Dependence of beach seine net efficiency on net length and diel period

The aim of this study was to quantify the efficiency of different lengths of beach seine nets for each diel period in freshwater reservoirs. Only...

The effect of depth, distance from dam and habitat on spatial distribution of fish in an artificial reservoir

Spatial distribution of the fish community in the deep canyon-shaped Římov Reservoir, Czech Republic, was studied using overnight gillnetting...

Size selectivity of standardized multimesh gillnets in sampling coarse European species

We studied gillnet selectivity by using a direct method to compare fish-size distributions from gillnet catches (Nordic type, mesh size range 5–135...

Diel variation in gillnet catches and vertical distribution of pelagic fishes in a stratified European reservoir

he diel changes in gillnet catch rates and vertical distributions of pelagic fishes were determined in a deep, moderately eutrophic European...

Effects of the construction of a reservoir on the fish assemblage in an inflow river

The construction of the Římov Reservoir on the Malše River in 1978 significantly influenced the fish assemblage within the river, above the...

Distribution patterns of fishes in a canyon-shaped reservoir

In August 2004 and 2005, an extensive study of the fish community was carried out in the largest water supply reservoir in the Czech Republic and...

The use of pelagic habitat by cyprinids in a deep riverine impoundment: Rimov Reservoir, Czech Republic

In the deep and slightly eutrophic dam part of the Rímov Reservoir (Czech Republic), the fish use of open water habitat was studied by means of...

Diet of larvae and juvenile perch, Perca fluviatilis performing diel vertical migrations in a deep reservoir

Feeding behaviour of two functional groups of 0+ perch Perca fluviatilis (epilimnetic, staying all 24 hours in epilimnion; hypolimnetic, daily...
