    Limnological changes in a pond ecosystem cause by grass carp (Ctenopharyngodon idella Val.) low stocking density

  • Original language description

    Grass carp (Ctenopharyngodon idella Val.) stocked (29 kg/ha) in a small pond reduced the biomass of aquatic macrophytes from 109 g/m(2) to 33 g/m(2) during one growing season. The only changes in hydrochemical parameters (pH, alkalinity, acidity, BOD5, CODMn, NH4-N, NO2-N, NO3-N, TN, PO4-P and TP) associated with the grass carp stocking were a decrease in pH (from 8.43 to 7.57) and in NO3-N concentration (from 0.99 mg/l to 0.56 mg/l). The increases in organic matter content and NO3-N concentration in the surface sediment layer were higher in the control pond than in the pond stocked with grass carp. No changes were detected in the other parameters (NH4-N, PO4-P and TP) in the upper sediment layer and between all parameters measured in the lower inorganic layer. The grass carp grazing had no impact on phytoplankton biomass (concentration of chlorophyll-a) or species composition. There were no changes either in the abundance or in the species composition of zooplankton and zoobenthos ind
