The results of rearing and feeding of the larvae of Lena or Siberian sturgeon (Acipenser baeri Brandt) were presented in the conditions rearing in live fish wells with different fish density in the Republic of Belarus. In the course of the research it was found that an increase in stocking density from 1.0 thousand to 1.5 thousand individuals/m2 individuals /square meter for rearing larvae of Lena sturgeon stimulates the development of food search reflex, reduces the period of the beginning of active feeding up to 8 days . The feeding with an increase in stocking density from 1.0 thousand up to 1.5 thousand pieces/square meter increases. With further increase in planting density reduced. The same dependence is characteristic for the index number of species consumed by zooplankton.
