We do not know reliably, what is the situation in Ukraine and on the territory of the Russian Federation known positive experiments of this crossing. However, to receive the intelligible F2 generation of such offspring is impossible, the fish loses the specific characteristics of the species, externally, it’s not like the “veil” of carp, lose the mustache, “leaves” in carp and gets symptoms of degeneration. There are also quite a scientific concept of the origin of the veiltail forms within species through a long process of breeding selection.

The silver carp eats all types of algae that occur in fresh water. Its power is supplied by filtering phytoplankton through a kind of arranged Gill apparatus. In Biotechnics of artificial breeding using the method of pituitary injections, where to produce offspring using the pituitary glands of fish / kg females. The ripening females after hypophyseal injections depends on the temperature conditions in the spawning basins. When ripe, the prevailing temperature of 21 – 26 degrees Celsius. Continue reading
