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.

There are some foods that are simultaneously rich in iron, phosphorus, zinc, magnesium, calcium, selenium, vitamins A, E, D, and amino acids that are necessary for the normal functioning of the cardiovascular system, thyroid gland and stomach. But in fish, all these elements abound. Therefore it is very importance of fish in human nutrition. In addition, this product small fat content (30%), it is perfectly assimilated by the human stomach digests the protein contained in fish, only 1.5-2 hours compared to 5 hours it takes to digest, say, beef.
The importance of fish in nutrition
People suffering from excess weight, just perfect river fish, which contains 2.5 grams of fat per 100 grams of weight. But suffering from diabetes can have it without any restrictions, because the number of carbohydrates it is small – only 0.1%.
Fish, competing in this regard with the chicken, is an excellent source of high quality protein which contains all necessary for normal functioning of amino acids. It also differs from meat protein by the presence of methionine.
Due to the fact that the collagen that makes up connective tissue, has the property of rapid transition in a soluble form, fish is easy to cook, and its tissues become loose, blagodaram provides maximum and rapid absorption of all nutrients. The most rich in protein fish include salmon, trout, and salmon, Beluga, easier to say that all representatives of groups of sturgeon and salmon. Great importance in human nutrition fish is also underpinned by a very high nutritional value due to high concentration of fatty acids. It refers to oily marine fish – salmon, mackerel, herring, trout, salmon and other things. Continue reading
It’s nice in the summer heat, having left the cottage, to sit by the water. And even better in their personal pond to catch the fish, right there on the grill to fry her and entertain your friends.

An artificial reservoir it is possible to arrange on a suburban garden plot.
First you need to decide for what purpose you will create a pond. If it is just decorative enough depth 60 to 70 cm, and the shape and size can be very different, depending on the capabilities and desires. If in a pond to live fish, size of pond you need to choose depending on the types of fish that will be grown. For example, for cultivation of ornamental koi the pond can be small, about 15 m2 and depth of 1.2 meters. Undemanding goldfish can live even in a tiny pond. But the ornamental fish you in the winter time you will need to move the aquariums, which do not freeze, are the winter garden or in the house. If you decide to breed fish for the pond. such as common carp, silver carp, Zander, catfish, bream, the water volume in the reservoir must be large with respect to the quantity of fish, and hence the partition of the pond not less than 15 square meters.
The pond should be placed in a location where it will be convenient to spend time, and planted coastal plants, plants for the pond and all living organisms of the pond felt good.
The choice of location for the reservoir
Do not place the pond in the lowland area, especially if it flooded. In the rainy season all the water will flow down, and if around or nearby flowerbeds, lawn or garden that you fertilize in the pond will be the entire set of the periodic table. Continue reading
