Lyutikov, A.A.
The influence of different artificial and natural (Artemia nauplii) feed, and their combination, on growth, survival and physiological state of the inconnu Stenodus leucichthys nelma larvae. In the diet of Artemia nauplii during the first 10 days of cultivation accelerates the growth rate of young fish in the 2.0–2.5-fold compared with the larvae, who received only artificial feed. In the future, the growth rate inconnu on Artemia and artificial feeds aligned, which is probably associated with the development of the digestive system of larvae and higher water temperatures, providing a fuller cleavage and digestion of feed components, especially artificial. The best biological indicators of juvenile fish were obtained by feeding with Artemia nauplii first days in combination with artificial diet. This approach allows the mutual compensation of each of the feed missing elements provides early schooling to dry food and makes it possible to more successful further transfer of juveniles only on artificial feed
