Carp breeding in ponds is a very old tradition in Europe. It requires a series of ponds each serving a different purpose. For example breeding ponds axe usually small artificial pools often overgrown with grass, which house female fish during the spawning period. After spawning the mother fish are removed and when the larvae have absorbed the egg yolk, they are taken out by fine nets and transferred to fry ponds.
There they stay until autumn, when they are again transferred to deep ponds, to overwinter. In spring the carp are transplanted yet again to another type of growing pond and in the autumn of the second year, when the carp weighs 200 to 500 g, it is relocated in deeper ponds. In the third year the young are put into the large, main ponds, in which by autumn they have reached the correct size for consumption, namely 1.5 to 3 kg.
