Comparison of 0+ juvenile fish community in the lowland stretches of the Morava and Dyje rivers
Valová, Z. ; Jurajda, Pavel
The 0+juvenile fish assemblages were compared in two differently modified lowland rivers. Phytophilous fish species were less abundant in more channelized and regulated river, however, rheophilous species were more abundant, probably due to shallow fast flowing places bellow weirs.
Importance of lentic waterbodies and managed flooding for natural fish reproduction of lower River Dyje
Bartošová, Š. ; Jurajda, Pavel
In 1997-1999, the 0+ fish communities of backwaters, oxbows and flooded and non-flooded borrow pits along the River Dyje (Danube basin) were investigated. Species richness was high in flooded borrow pits and backwaters. Abundance was high in flooded borrow pits and oxbows. Non-flooded borrow pits present pure 0+ fish community.
Variability of natural reproduction of fish in the floodplain area
Bartošová, Š. ; Jurajda, Pavel
The 0+ fish communities of eight gravel pits along the River Dyje were investigated by electrofishing using the point-abundance sampling strategy in three years. Composition and quantity of 0+ fish communities were different among years.
Strategies of fish drift in lowland rivers
Reichard, M. ; Jurajda, Pavel
The diversity of strategies of fish drift (i.e. downstream transport of early development stages) were studied at global and regional (Central Europe) scales.
Expansion of tubenose goby (Proterorhinus marmoratus) in the Czech Republic
Prášek, V. ; Jurajda, Pavel
The first record of several specimens of tubenose goby (Proterorhinus marmoratus) was in 1994 from the single place of stony bank of upper lake of the Nové Mlýny reservoirs, far away from its original distribution area.is spread around the whole lake and penetrated downstream to the second and third lake further downstream to the Dyje river.
Diversity of 0+fish communities of two different stretches of the lower River Morava
Jurajda, Pavel ; Reichard, M. ; Černý, J. ; Hohausová, Eva
Recruitment of 0+fish in two lowland stretches (regulated-channelised and floodplain) of the River Morava was assessed.
Composition of 0+juvenile fish community in the lower floodplain stretch of the River Dyje
Bartošová, Šárka ; Jurajda, Pavel
The occurrence of 0+juvenile fish was observed using point abundance sampling strategy in four different types of water bodies, i.e. in gravel pits, oxbows and backwatres in the floodplain of the River Dyje (Danube basin) in August 1998.
