Who Is Who: An Anomalous Predator-Prey Role Exchange between Cyprinids and Perch

Piscivory in cyprinids (Cyprinidae) is extremely rare. Specifically, common bream (Abramis brama) and common carp (Cyprinus carpio) are...

Deficiency and toxicity of nanomolar copper in low irradiance-A physiological and metalloproteomic study in the aquatic plant Ceratophyllum demersum

Essential trace elements (Cu2+, Zn2+, etc) lead to toxic effects above a certain threshold, which is a major environmental problem in many areas of...

Small fish use the hypoxic pelagic zone as a refuge from predators

1) Juvenile perch (Perca fluviatilis) often inhabit deep zones of lakes or reservoirs (metalimnion to hypolimnion). Using fry trawling and...

Fish community response to the longitudinal environmental gradient in Czech deep-valley reservoirs: Implications for ecological monitoring and management

Ecological quality assessment of non-natural water bodies is, in contrast to natural systems, less developed and requires determining biological...

Pelagic occurrence and diet of invasive round goby Neogobius melanostomus (Actinopterygii, Gobiidae) juveniles in deep well-mixed European reservoirs

Round goby is generally accepted to be a typical benthic dwelling fish species both in its native and invasive ranges. Nevertheless, mid-water night...

Antibacterial properties of palladium nanostructures sputtered on polyethylene naphthalate

Resistance of pathogenic bacteria to conventional antibiotics has emerged in recent years as a major problem for public health. In order to overcome...

Fish behaviour in response to a midwater trawl footrope in temperate reservoirs

This study addresses fish behaviour at the mouth of a midwater trawl in two temperate reservoirs. Fish distribution and behaviour were monitored...

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...
