The presence of omnivorous fish is known to affect aquatic ecosystems, including water quality. The effect, however, depends on the species in question, and our knowledge is limited on the effect of omnivorous crucian carp (Carassius auratus), a common and often the most numerous fish species in eutrophic shallow lakes in China. We conducted a 70-day outdoor experiment in mesocosms with and without crucian carp to examine whether this species adversely affects water quality by increasing the levels of total nitrogen (TN) and total phosphorus (TP), thereby stimulating the biomass of phytoplankton and increasing water turbidity. Compared with carp-free controls, the presence of crucian carp resulted in higher TN and TP in the water column, greater phytoplankton biomass and lower periphyton biomass, measured as chlorophyll a. Total suspended solids (TSS) also increased in the presence of fish. We conclude that crucian carp can increase TN and TP, enhance phytoplankton biomass, and increase water turbidity, thereby contributing significantly to the deterioration of the water quality. In addition to controlling external nutrient loading, the removal of crucian carp may help to improve water quality in warm shallow eutrophic lakes.

Impact of Nutrients, Temperatures, and a Heat Wave on Zooplankton Community Structure: An Experimental Approach
Iskin, Ugur; Filiz, Nur; Cao, Yu; Neif, Erika M.; Oglu, Burak; Lauridsen, Torben L.; Davidson, Thomas A.; Sondergaard, Martin; Tavsanoglu, Ulku Nihan; Beklioğlu, Meryem; Jeppesen, Erik (MDPI AG, 2020-12-01)
Shallow lakes are globally the most numerous water bodies and are sensitive to external perturbations, including eutrophication and climate change, which threaten their functioning. Extreme events, such as heat waves (HWs), are expected to become more frequent with global warming. To elucidate the effects of nutrients, warming, and HWs on zooplankton community structure, we conducted an experiment in 24 flow-through mesocosms (1.9 m in diameter, 1.0 m deep) imitating shallow lakes. The mesocosms have two nu...
Role of planktonic bacteria in biodegradation of fish-exuded kairomone in laboratory bioassays of diel vertical migration
Beklioglu, M; Gözen, Ayşe Gül; Zorlu, P; Ay-Zog, D (Schweizerbart, 2006-01-01)
Daphnia, freshwater crustaceans that graze algae, often rely on predatory chemical cues termed kairomones as signals for predator-avoidance. Using laboratory bioassays, we studied how planktonic bacteria may modify kairomone activity. We measured the amplitude of diel vertical migration (DVM) of Daphnia pulex DE GEER among treatments with different amounts of bacteria. We used temperature incubation to increase bacterial densities and filtration to reduce abundance. Daphnids exposed to fish cue (F) and filt...
Effects of water temperature on summer periphyton biomass in shallow lakes: a pan-European mesocosm experiment
Mahdy, Aldoushy; Hilt, Sabine; Filiz, Nur; Beklioğlu, Meryem; Hejzlar, Josef; Ozkundakci, Deniz; Papastergiadou, Eva; Scharfenberger, Ulrike; Sorf, Michal; Stefanidis, Kostas; Tuvikene, Lea; Zingel, Priit; Sondergaard, Martin; Jeppesen, Erik; Adrian, Rita (2015-07-01)
Periphyton communities play an important role in shallow lakes and are controlled by direct forces such as temperature, light, nutrients, and invertebrate grazing, but also indirectly by planktivorous fish predation. We performed a pan-European lake mesocosm experiment on periphyton colonization covering five countries along a north/south geographical/temperature gradient (Estonia, Germany, Czech Republic, Turkey, and Greece). Periphyton biomass on artificial polypropylene strips exposed at 50 cm water dept...
Impact of zooplankton grazing on phytoplankton in north temperate coastal lakes: changes along gradients in salinity and nutrients
Christensen, Inge; Pedersen, Lisbeth Kjæreby; Søndergaard, Martin; Lauridsen, Torben L.; Tserenpil, Sh.; Richardson, Katherine; Alves Amorım, Cıhelıo; Pacheco, Juan Pablo; Jeppesen, Erik (2022-10-01)
Zooplankton grazing at similar nutrient levels is generally regarded as lower in brackish than in freshwater lakes, but experimental evidence of this is lacking. Accordingly, we conducted short-term zooplankton grazing experiments in bottles with water from 12 Danish brackish lakes covering a large gradient in salinity (0.3-17.4 parts per thousand) and nutrient concentrations as well as with water from 24 mesocosms established in the same area with various salinities (0.5-12 parts per thousand), two nutrien...
Influence of Farming Intensity and Climate on Lowland Stream Nitrogen
Goyenola, Guillermo; Graeber, Daniel; Meerhof, Mariana; Jeppesen, Erik; Teixeira-de Mello, Franco; Vidal, Nicolás; Fosalba, Claudia; Ovesen, Niels Bering; Gelbrecht, Joerg; Mazzeo, Néstor; Kronvang, Brian (MDPI AG, 2020-4-2)
Nitrogen lost from agriculture has altered the geochemistry of the biosphere, with pronounced impacts on aquatic ecosystems. We aim to elucidate the patterns and driving factors behind the N fluxes in lowland stream ecosystems differing about land-use and climatic-hydrological conditions. The climate-hydrology areas represented humid cold temperate/stable discharge conditions, and humid subtropical climate/flashy conditions. Three complementary monitoring sampling characteristics were selected, including a ...
