Abstract

During the evaluation of broodstocks on the basis of the Federal Fish Breeding Genetic Center (FSGTSR), rainbow trout females maturing with an interval of 6 months were found. It has been established that under conditions of RAS, females with bicyclic spawning can produce the same full-fledged reproductive products of high fish-breeding quality, as well as producers with a normal sexual cycle. It has been suggested that maturation every six months of only a part of females indicates the genetic predetermination of individual fish to the appearance of this feature. The breeding of domestic breeds of rainbow trout with bicyclic spawning will also greatly contribute to the realization of the biological potential of this species and open up new prospects for trout breeding in Russia.
