For the keeping, breeding and rearing fish use of different ponds: lined, dug, used peat quarries and instream ponds, cages and basins, small reservoirs and lakes.
The operation and construction of pond intended for fish production, requires compliance with certain rules, which correspond to fish and hydraulic requirements. First, you should determine the orientation of use of the reservoir, i.e. it is designed for the cultivation of food fish or for use in the design of the site. This will depend on its size, the device of the reservoir, depth, shape, mode of operation.
A pond for the cultivation of food fish is very different from the devices of decoration. To this reservoir are a bit different requirements. It does not make sense to do complex bottom topography, indented coastline, depths off the coast, laying on a bed of special soil, decorative elements. The main attention should be paid to the layout of the bed of the pond, the supply of the reset options and a good water supply. Fish farming will benefit, assuming the decision of questions of operation of the reservoir and construction. If the device pool determines much the size of the land plot, which is released under the dispensing reservoir. On the one hand, this ustroistvom or group of water bodies on a farm with a large land area, with another pond in the garden. We must remember that the pond in the garden mostly satisfied mostly your own needs, while the farmer needs to determine how important will be the farming in agricultural production. Following from this, determine its place in economic activity. Perhaps it will be agriculture, where the cultivation of fish will be your main activity or fish farming will become an integral part of the farm with the use of the reservoir complex. The latter area has received wide distribution as well as cultivation of fish goes well with other branches of agricultural production. Hence in the construction of the pond should not exclude the possibility of comprehensive use, for example for watering livestock, watering the garden, fire fighting purposes, breeding waterfowl.

Pond fish farming is a type of economic activity. which uses high-yielding species for cultivation in specially equipped natural and artificial water bodies for the purpose of receiving all kinds of fish products.
Pond aquaculture also includes the complex of measures on construction of fish ponds, swimming pools and other bodies of water: the digging of ditches, dams and levees, water supply and water discharge facilities, rybolovleva, etc.
This includes scientifically developed techniques for breeding, artificial reproduction, feeding and the optimum conditions of the fish to ensure a productive outcome.
The content of fish in pond fisheries.
In the same pond can be kept as a single species of fish, and several species simultaneously. Remember to take into account the characteristics of each species and their mutual compatibility. Some species of fish require cold flowing water saturated with oxygen, another — warm standing water with lots of organics and small amount of oxygen. Some species of fish to mohalalitoe only in freshwater, some in saltwater, and there are those that can live in that.
To a cold-water fish include trout. burbot, pike, salmon, Arctic Cisco, grayling and others.
The technology of fish culture and fisheries include not only the maintenance of a temperature mode. This includes providing fish with oxygen, water disinfection, filtration of harmful components and toxins, prevention of the disease. the fertilizer ponds. the destruction of noxious vegetation and various wastes, maintaining appropriate pH and other measures.
