A carp pond is a standing waters artificially put on, which serves the economical production of carps and other fish types (see carp fish), those for this type of waters is suitable (Schleie, Hecht, Zander).

The management of a carp pond is a form agricultural land use and corresponds in the range of the fishery of a pastoral industry. By fertilization of the water body primary production becomes lively. Over the stages so as high a production at fish as possible is to be made possible for the food chain.

The construction of this type of waters corresponds to the described economic goal. Fertilization brings a normal lake by the fact to tilting that the depth layer becomes free Hypolimnion by the high biomass accumulation by oxygen. A carp pond is put on so flat against it (approx. 1 - 2 meter) that the mixing can bring in new oxygen daily up to the soil.

Carp ponds must be abgefischt in the autumn. Therefore each carp pond receives an expiration building, the so-called monk. It contains an expiration on height the pond soil, so that the pond can be completely emptied. The pond soil is too put on in form of a very flat funnel on the monk. Thus the fish collect themselves when discharging with the removing water level before the monk.

The monk consists of a box over the expiration pipe, into which two parallel rows of dust rescuers can be inserted. The expiration-lateral (the inside of the box turned) row of boards is as highly used, as the water level to be is (dust rescuers). The pond-lateral row of boards begins to over finally fall over the pond soil with a lattice employment, by which the depth water can occur and ascend between the two board rows, over the expiration-lateral dust-saved into the expiration pipe.

Carp ponds are usually built in gradated groups, in order to be able to keep several age groups of the fish separate into succession. Accordingly one differentiates between Laichteiche, breeding ponds and Abwachsteiche for different classes of the fish.

The water supply takes place in some areas (e.g. in middle Franconia: Aischgrund) only by the rain. One calls such ponds "“sky ponds"”. Their water is kept if possible and used with Abfi for filling the next pond lain somewhat more deeply. Each case the Wasserzulauf is limited by carp ponds the summer over to a minimum (reconciliation of evaporation and infiltration, approx. 1 l/s per hectare of surface), in order not to lose nutrients and nature food.
