The data were collected from experimental freshwater fishpond systems (extensive, semi-intensive and semi-intensive coupled with lagoon). The dataset presented is composed of: - Individual Fish parameters (live weight, length at fork) at stocking and harvest for the three species reared: common carp (Cyprinus carpio), roach (Rutilus rutilus) and tench (Tinca tinca). - Physical indicators of the water quality in pond, monthly measured :temperature, pH, conductivity, dissolved oxygen, oxygen saturation and water transparency - Physical indicators of the water quality in pond, measured every 5 minutes on 24h in September 2014: temperature, pH, oxydo-reduction potential, conductivity, dissolved oxygen and oxygen saturation. - Concentration in pond water of chemical compounds , monthly sampled :total nitrogen (TN), ammonium, nitrite, nitrate, orthophosphate and total phosphorus(TP) -  Concentration in pond water of chemical compounds, sampled 5 minutes on 24h in September 2014: TN, ammonium, nitrate, orthophosphate, TP - Concentration of chlorophyll in pond water monthly sampled: chlorophyll-a from March to June and total chlorophyll, blue chlorophyll, green chlorophyll and brown chlorophyll from July to November. - Concentration in TN and TP in the sediment of each pond at fish stocking and harvest.
