Requirements to breeding economy on cultivation of klariyevy som VUZV (Clarias gariepinus burchell)
The work considers requirements to the establishment of a pedigree fish farm on breeding and raising clay catfish under the conditions of the closed water supply (CWS). The present Regulations in the field of livestock breeding (fish breeding) are developed in accordance with the Federal law dated August 3<sub>rd</sub>, 1995 № 123-FZ «About livestock breeding». They allow activate breeding work with many objects of aquaculture and establish breeding farms for new cultivated objects including clay catfish. In the article there are presented requirements to the breeding factory and reproducer. There are given normative data on the hydro chemical regime of breeding farms basins, breeding density of the breeding material, industrial method of clay catfish reproduction, assessment (class) of the quality of producers. The best variant of creation of a breeding farm for clay catfish in RF is CWS. A farm of clay catfish breeding has some principal positive moments in comparison with other farms engaged in breeding - a pedigree work with other kinds of fish. Thus, water of water fish basins does not require an additional saturation with oxygen; density of growing this object is higher than of trout, sturgeons and other fish. The disadvantage during clay catfish breeding is that the number of males is larger by 3 times due to the death of males after milts withdrawal during reproduction.
