Species-specific gradients of juvenile fish density and size in pelagic areas of temperate reservoirs

Data from nine reservoirs in the Czech Republic were used to investigate density and size distribution patterns for dominant fish species of the...

An assessment of the ecological potential of Central and Western European reservoirs based on fish communities

In this study we developed a novel methodology based on fish communities to assess the ecological potential of central European reservoirs. Using the...

Biomass and Abundance Biases in European Standard Gillnet Sampling

The European Standard EN 14757 recommends gillnet mesh sizes that range from 5 to 55mm (knot-to-knot) for the standard monitoring of fish assemblages...

Patterns in diel habitat use of fish covering the littoral and pelagic zones in a reservoir

We investigated diel habitat use of fish covering the littoral and pelagic zones of the Římov Reservoir (Czech Republic) and analyzed the influence...

Planktonic or non-planktonic food in young-of-the-year European perch Perca fluviatilis in ponds

Higher biomass especially of some aquatic macrophyte species offered a higher density of phytophilous zoobenthos, but did not increase the proportion...

Dinitrogen fixation associated with shoots of aquatic carnivorous plants: Is it ecologically important?

Background and Aims Rootless carnivorous plants of the genus Utricularia are important components of many standing waters worldwide, as well as...

Towards a better understanding of small scale distribution of littoral age-0 fish in a deep-valley reservoir: day or night surveys?

The effect of diel period and littoral habitats on the distribution of age-0 fish was tested in a deep-valley reservoir using boat-modified point...

Chaos and stability of age-0 fish assemblages in a temperate deep reservoir: unpredictable success and stable habitat use

Large year-to-year variability in different fish species recruitment has been confirmed by previous studies while diurnal patterns of occupation in...

Occurrence of age-0 year dwarf pikeperch Sander lucioperca in late summer – an overlooked phenomenon in reservoirs

Late summer sampling of pelagic age-0 year fish communities in five Czech reservoirs and one Dutch reservoir revealed extremely small age-0 year...

Extremely shallow spawning of perch (Perca fluviatilis L.): the roles of sheltered bays, dense semi-terrestrial vegetation and low visibility in deeper water

The roles of wind protected bays, presence of littoral vegetation and light attenuation in the water column on spawning site selection and depth of...

What do results of common sequential fractionation and single-step extractions tell us about P binding with Fe and Al compounds in non-calcareous sediments?

Correct identification of P forms together with their main Fe and Al binding partners in non-calcareous sediments is of crucial importance for...
