Crucian carp feed both on benthic prey (Chironomidae) and on pelagic prey (Cladocera). Based on that, this experiment aimed to test the indirect interactions between Chironomidae and Cladocera prey due to shared predation, and how these interactions changed in response to nutrient additions through changes in benthic and pelagic food-web pathways. In the dataset there are five different sheets: Sheet number 1 shows the summary values of all the variables after the fish were added. Most variables are shown as mean values over a 7-week experimental period (after fish addition). The other sheets show the time-series of food-web variables (Phytoplankton Chla, periphyton biomass, Chironomidae emergence and Cladocera abundance), where the week refers to week relative to fish addition (week 0 is the first week after fish addition). The dataset was originally published in DiVA and moved to SND in 2024.

The food web was exposed for organic contaminants and treated with different scenarios mimicing future climate changes (temperature- and dissolved organic carbon-treatments). The data files contains information on water chemistry and biological responses over time, as well as data specifically on fish survival and organic contaminant concentrations in fish and water.
