Is better to make, of course, a pond in capital execution with concrete or ferro-concrete walls and a bottom. Such pond can be an original work of art. It can give any form, any profile, with deepenings, steps, banks, underground niches etc. All depends on the location of a pond, other conditions and taste of the owner. However in any case it should not look a usual ditch. Even if the pond will be used only in the economic purposes, say, that in it ducks floated, and water went on having watered a kitchen garden and in that case it should be well issued and well-groomed. During winter time it is possible to warm, close, warm a pond.
Is better to do a reservoir with sites of different depth. On small sites water is better gets warm, develops zoo- and a phytoplankton which is a natural forage for fishes is better. Different fishes will keep on the different depths, different water plants also will select different depths.

Plants land in a ground which keeps within on terrasnyh deepenings or in the special containers lowered on a bottom. The terraces intended for landing of water plants, become not equal as a bench, and are framed with concrete sides that the earth was not washed away and did not fall on the bottom steps or a bottom.
The Sizes of a pond in house conditions depend on presence of a place and other conditions. If to speak about cultivation or dorashchivanii fishes the pond in the size in ten square metres is sufficient. At intensive technology it is possible to remove good enough "crop" of fish which will suffice not only for a family table from such area, but also the part can be realised it.
to What fish to prefer.
Selecting fishes for installation and cultivation, it is necessary to consider, first of all, that circumstance that some of them are unpretentious, for example, a crucian, a carp, a tench and others. One of them live in benthonic sheets of water - a crucian, a tench, vjun, golets. Others - in top and the water middle class - verhovka, small fry, ram, krasnoperka. Therefore at a choice of fishes it is necessary to start with available conditions and a forage reserve which you can create for the fishes. And secondly, it is necessary to be guided by those which life and technology of cultivation more all is studied. Thirdly, it is necessary to consider, what fishes are the most easier for getting in the given district for landing in a pond. However, for the sake of interest it is possible to plant in the pond and those fishes who are a little studied, behind them it will be possible to observe, learn their "character" and requirements. At the same time some conditions all the same need to be considered. What for, for example, to go on an extreme measure and to instal belugu which for the long life can reach length of five metres and weight - to one ton? As malkov some this fish not to find, it is on the verge of disappearance and on it lov the absolute prohibition is imposed. Same concerns and variety of other fishes, such, as, say, kaluga, a sturgeon, sevrjuga, a thorn, a salmon and some other.
There is no sense to instal in the closed marshy pond of fishes which love pure flowing water. In your pond holodoljubivaja fish, after all a water temperature in it at any time year, especially in the summer, high enough hardly will get accustomed. However, as experience of one-two nalimov it is possible to hold. It is difficult to provide with a forage in a full prosperity and such fishes, as zhereh, a pike, a catfish, a pike perch, black and white cupids. Though at good knowledge of their biology it is possible to risk. Therefore fishes should be selected such for which in a reservoir it is possible to create normal conditions zhizneobitanija. It is desirable to grow up the most various fishes not stirring each other, of course. It can be, for example, peace and predatory fishes simultaneously. Such coexistence is possible, if peace fishes are larger some predatory fishes. Grown up fishes accustom to periodic feeding carried out at the same time. Thus, it is necessary to proceed from concrete possibilities and conditions, and also - taking into account your initiative and enthusiasm.
