Zapletal, J. ; Peňáz, Milan ; Baruš, Vlastimil ; Prokeš, Miroslav ; Vojtásek, S.
The diversity of the fish community was investigated in the Morava river oxbow (r. km 268.4) in 1998-1999.
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.
Morphometry and growth variety of sturgeon species reared in the Czech Republic in 1994-1999
Prokeš, Miroslav ; Baruš, Vlastimil ; Peňáz, Milan
The present paper reports the results of assessing the differences in biometrical characters and growth features in six sturgeon species which were introduced in the Czech Republic from the USA and Russia in 1994-1996.

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.
Wild Danube carp (Cyprinus carpio carpio m. hungaricus Heckel, 1836) - its past, present and future in the Czech Republic
Lusková, Věra ; Lusk, Stanislav ; Holčík, J. ; Halačka, Karel
Regarding the fact that the original wild form of the Danube carp is now at the edge of its extinction, we consider its rescue to be highly actual. In this action, of course, also other Danubian countries should participate under the auspices.
Action plans in the ichthyology
Lusk, Stanislav ; Lusková, Věra ; Hanel, L. ; Halačka, Karel
The so-called action plans should enable the support of populations or the restauration of extinct populations of endangered species.
The actual state and occurrence of sculpin (Cottus) in some streams of Frýdek-Místek dictrict
Lojkásek, B. ; Lusk, Stanislav
Ichthyological research focused on the frequency of common sculpin and Carpathian sculpin was performed in 28 rivers in the Beskydy region of the Oder river catchment area.
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.
Fish assemblages in artificial created pools in floodplain forest
Horák, Václav
The artificially created pools can be significant part of the revitalized water system of flood plain forests. As to their function, very important is the connection of the pool to the hydrological system of the alluvium (permanent flow).
The ichthyofauna and migration permeability of the River Otava
Hartvich, P. ; Lusk, Stanislav
The River Otava (a tributary of the River Vltava, Elbe drainage area) belonged in the past to the known rivers where Salmo salar were immigrating to spawn. On the Otava stream, in total 33 transverse steps of various types were built, which constitute mostly insurmountable barriers to fish migration.
