| Description
| - Pond farming is tightly linked to its surrounding environment, influencing it and also influenced by it. Pond management can substantially modify the hydrological regime and ecological quality of receiving waters, usually rivers, canals, reservoirs and ponds downstream, with positive or negative potential impacts on watershed function. To study the potential ecological consequences of carp farming in ponds, water quality at inlet and outlet canals during the fish growing season was evaluated in ponds subjected to a range of pressures and management styles. Selected study sites included ponds supplied partly or fully with unpolluted river water and water discharged from wastewater treatment plants. Ponds with different management intensity (extensive and/or semi-intensive), stock biomass and inlet water quality were selected. Water quality parameters were monitored monthly at inlet and outlet canals of each pond during the growing season. The decrease in nutrient concentrations was observable in all monitored forms of N and P, namely NH4-N, NO3-N, total N, PO4-P and total P, which indicate nutrient retention by the pond, confirming that ponds have significant self-cleaning abilities. Contrary to nitrogen and phosphorus concentrations, the content of total organic carbon and suspended solids increased at pond outlets because of increased primary production. A significant decrease in bacterial loading was measured. Properly managed Czech carp fish ponds are safe for the environment during the growing season, serving not only as fish-producing facilities but also as important sinks for nutrients and as effective natural biofilters and digestors of various organic wastes. Nevertheless, pond harvesting represents a potential risk to receiving waters because of suspended solids and nutrients during pond drawdown and fish harvest.
