“The trade of fish native case of thieves. And therefore, the salary for them to put miserable, but to hang one in the year that others do not want.”
An artificial pond for breeding fish.
However, the creation of artificial water bodies (ponds) for breeding fish in home gardens has become a very popular hobby in recent years, and our firm is very actively developing this area of its activities, with qualified specialists in this field.
The pond, unlike lake is a water body of artificial origin.
The types of ponds can be divided into flowing and isolated, which in turn conventionally divided into fishing and no fish, but aquatic vegetation (the already and the other is pools).
Strictly speaking, the pond (if not abandoned) – this tank with semi-open water system and controlled filling plants and animals.
Safety performance of the ponds are:
soil (natural ground coming off the pit and filled with water),
concrete (in the ground cast a bowl made of reinforced concrete with subsequent finishing and waterproofing),
film or plastic (modern materials of high strength, resistant to corrosion).
On sposobnostyami water ponds can be running or closed.
The flow-through pond is when the water is supplied from an external source (e.g., stream or well) and excreted into the drainage system on the site. Such ponds are typically unpaved.
In the case of closed ponds, water circulates through the water treatment system filtration and subjected to special treatment, ensuring comfortable conditions for keeping fish and plants in the pond.
Each technology has its advantages and disadvantages. But the most durable, reliable and easily controllable is of course the pond with a concrete bowl and a water circulation system.
In any case, need proper maintenance and respect for the fundamental determinants of conditions of living organisms in the pond.
The main factors.
It is very simple, shiver at once. Here are the main factors determining the quality of the content of freshwater fishes in open water bodies of the Moscow region:
1. Abiotic factors.
This factor is determined by the physico-chemical parameters of the reservoir and the near shore environment. The main parameters are:
