ACCELERATED BUILDING OF STERLET PRODUCTIONAL SCHOOL
Abstract
The paper declares that effectiveness of building productional breeding flock depends mainly on the quality of feeds applied. Development of valuable feeds requires knowledge about fish food spectrum in natural conditions. The data analysis about sterlet’s food preferences allowed developing the special combined feed for replacement stock and its producers. New special feeds allow accelerating of starlet replacement breeding flock building from the natural population. The authors recommend controlling physiology of sturgeons population when keeping them. The blood characteristics of fish allows making conclusion about growing conditions and energy value of feeds. Appropriate and correct applying of valuable combined feeds balanced on essential aminoacids, fatty acids and vitamins influences sturgeons population of replacement breeding flock blood composition and their physiology. The authors developed a test-diet for starlet, which has similar composition of nutrients to the natural feeds. The research results of growing starlet replacement flock by means of applying new combined feed demonstrated positive influence on fish physiology and their productional properties.
