In the wild this fish niceley rivers, lakes, ponds and all dents filled with water. Carp undemanding and can live in flowing and stagnant water. In nature, fish may have different color variations, depending on ambient conditions. The most important of these conditions is light. Continue reading
Pond fish farming is the breeding of commercial fish in specially adapted or constructed for this purpose reservoirs. Farms can be full (full system) or incomplete (napolnitelem). In full system retailing the fish grow from egg stage to marketable, and in breeding — pedigree producers for full-cycle hatcheries and commercial farms.
Not in full-cycle farms planting material is grown marketable fish. They are of two types. The widest form of fish farming is feeding the carp fish farm . Spring here are imported from hatcheries to fingerling of carp weighing up to 30 grams, put them in the fattening ponds,in the fall catch of marketable fish with an average weight of from 500 to 800 grams. To grow fish in feeding the economy easy and accessible to everyone farming.

For the pond, choose a Sunny place, well, if it will be protected from the cold wind. Try to pick a place away from trees, or deciduous, their leaves will decompose and form gases and substances harmful to fish and promote algae growth. Especially harmful is the foliage of willow, Holly, horse chestnut and bobovnik. Ponds free-shape form is better positioned at the lowest area of the garden.
