Abstract: 

Damage of caviar in the course of an artificial fertilization, and also the high expense of trophic substances of a yolk of caviar during the period blastulogenezis are accompanied by intensive oxidation of lipids with superfluous formation free radicals bonds. In the course of intracellular digestion as a result oxidation of lipids high-toxic products free radicals oxidations – malondialdehyde and diene conjugates are certainly formed. This condition is characterized as oxidative stress, which increases the activity of free radical oxidation and is depressed antioxidant defense system. The effect of oxidative stress on morphofunctional condition of the digestive system embryos and larvae of mirror carp produced by traditional and innovation breeding technologies. The role of lipid peroxidation in damage to the epithelial cells of the intestinal mucosa of larvae carp.Caviar processing "Thiophane" аntioxidantat critical periods of development ensures the rational use of material resources trophic yolk in the embryonic period and contributes to early formation of optimum body shape. "Thiophane" аntioxidants during critical periods of development helps to normalize the digestive processes in fish and increase their adaptive capacity.
