The method of determining the effectiveness of artificial reproduction works is considered on the example of the Ob population of peled. The method is based on recording the moment when the population decline stops, and the subsequent increase in catches. Based on the average fishing return rate of 0.258% of the 1.5 g young, the catch from one million young is about 0.8 tons. It is established that the catch can increase to 2.6 tons per one million juveniles after the entry into the fishery of new offspring from the replenishment of the spawning herd. Taking into account the mass onset of sexual maturity of the peled at the 4th year of life, the greatest effect of artificial reproduction is observed at the 8th year. The equations for determining the period and level of restoration of the bioresource are given. It is noted that for the restoration of long-cycle fish species, the volume of young fish introduction should be at least 20 % of the receiving capacity. The rate of recovery of the bioresource depends on the following indicators: the volume of the introduction of juveniles, the intensity of fishing, the age of sexual maturity and the availability of conditions for natural reproduction.
