Management of fish pond farming involves diverse practises aimed at increasing fish productivity, such as polyculture stocks, supplementary artificial feeding, adding nutrients, or drying ponds during winter or summer. Since aquatic vegetation has a

Rhynchotalona falcata (G.O. Sars, 1861) was found in the plankton of a gravel pit located in the lowlands of Slovakia. This is the first record of this taxon for Slovakia, although it is widely distributed in Western Europe. We do not know to date, w

The present study investigates the relationship between hydrological connectivity and species diversity in a by-passed channel section, and in the adjacent water bodies of the Slovak–Hungarian Danube section (1,840.5–1,804.4 rkm). The study was d

In spite of many investigations about the impact of reservoirs on river continuum, the downstream effects of a pumped-storage hydropower plants (PSHP) still have been less known. The aim of the study was to evaluate the downstream effect of the PSHP

Planktonic crustaceans are traditionally identified based on morphological and morphometric characters. However, such characters may be hardly distinguishable and often overlap between species. A probability of misidentification is thus relatively hi

The seasonal development of the phytoplankton, phytobenthos, zooplankton, and microbenthos in a high eutrophised intravilan water reservoir was studied. Finally, 25 genera with 44 species of Cyanobacteria/Cyanophytes and 67 genera with 102 species as

Our study summarizes data from six small water reservoirs in West Slovakia and analyzes the occurrence of zooplankton groups in relation to physico-chemical and catchment variables. The reservoirs are in two different catchments – of the Morava and

The historical influence of landscape on the quantitative variables and a special group of hyporheos in streams with similar origin but different catchment landscapes and forest management was studied. The study was conducted in two streams: (i) a pr

Poor quantity of zooplankton was recorded in a Danube arm situated on the right side of the Danube River in Slovakia (river km 1857) in 2002 and 2003. All over the year the arm is significantly influenced by groundwater by reason of seepage. Because

The species composition, seasonal dynamic of biomass and density of zooplankton were studied in two arms with a different hydrological regime. The samples were collected in two hydrologically different years — extremely wet in 2002 and extremely dr
