In recent years it has become fashionable and prestigious dacha or cottage on a plot to equip a pond. Of course the owner of this pond I want to breathe new life into them. The simplest solution is to run them in fish. And then the question arises, – what?
Categories of fishes can be divided into two types – decorative and domestic.
To include ornamental goldfish and koi carp. Goldfish is relatively small. Grow up to 30 cm koi can grow up to 60-80 cm unfortunately, not every breed of goldfish perfect for a pond. In open water may be in the breed, so called, the long-bodied fish. This is comet, shubunkin, simple gold fish (without rocks).
It makes no sense to buy expensive breed koi. It will fit the standard red and white colouring.
The only rule for ornamental fish is quarantine. Quarantine is done in order to reveal diseases. It should take place in the aquarium and should last at least two weeks. All types of ornamental pond fish bred in Asia and have many diseases.
To keep ornamental fish in open ponds can be to a temperature of + 10 C. (to October). In winter, Pets are transferred to aquariums or indoor heated ponds.
Ornamental fish need care. They should be fed each day. In zoomagazinvid special balanced feed for pond fish. If you pond is not flowing, you will need a biological pond filter, which can also be purchased at a pet store. In addition, once a week should substitute 10 % of the old water with fresh. If you have a pond with running, the need for the biofilter and there is no substitution.
The next type is a local fish, which can also be divided into categories.
The first category of fish that can hibernate in ponds under ice. In this case, the pond should be sites of at least 1.5 meters deep. Such fish include crucian carp (silver and Golden), carp, tench, IDE and roach.
The second category of fish that can live in a pond before freeze-up. It is a white Amur, silver carp, sterlet.
For all domestic fish as a General rule with a decorative fish – feeding, biofiltration and substitution of water (not flowing water bodies).
Next I want to mention some of the nuances associated with the content of the fish. For example, grass carp is herbivorous fish and plant needs constant feeding. Here will fit any greens (even the ordinary grass). The silver carp feeds on phytoplankton (small single-celled algae), so the pond should be located with them on the Sunny side. Under the influence of sunlight in the water will begin to flourish algae, which carp will eat. Specially to feed them is not necessary. Other feeds he is not.
This last category is a fish that can live only in flowing, non-freezing water bodies. These include trout, whitefish, perch, pike, ASP, Chub and many others. In such reservoirs contain (and even bred) cancers.
