Abstract Background This study examines seasonal and regional trends in chlorophyll-a concentrations and the dynamics of nitrogen (N) and phosphorus (P) in 32 fishponds (resulting in 150 pond-year cases) employed for fish production. Fishponds have a

Fishponds with a relatively small water volume, high fish abundance, and wide range of nutrient concentrations serve as suitable models for ecological studies. Intensified fish production, together with increased input of nutrients from the watershed

We studied macrophyte and diatom assemblages and a range of environmental factors in the large hypertrophic Dehtář fishpond (Southern Bohemia, Czech Republic) over the course of several growing seasons. The spatial diversity of the environment was

The results of long-term screening of sediments from the Czech Republic from 2011 to 2017 are presented, more than 80% of the samples of which were taken from fishponds. The total sediment volume of Czech Republic fishponds is estimated to be 197 mil

Fishponds exhibit high natural retention potential for phosphorus, which enters the ponds from non-point, diffuse and point sources, as well as from aquaculture management. Results of phosphorus mass balance monitoring of nine large fishponds (60–4

High eutrophication is the main factor that has recently disabled the Jordan water reservoir for water supply and recreational purposes. Large-scale dredging of sediments was done between years 2011 and 2014. Thereafter a complex monitoring of water

Recent technological developments have increased the number of variables being monitored in lakes and reservoirs using automatic high frequency monitoring (AHFM). However, design of AHFM systems and posterior data handling and interpretation are curr

Fishponds were and are purposeful water structures. Fish production is their main function and rational management is an inevitable condition for their existence. The present high level of fishpond eutrophication results in nutrients overloading. The
