FIELD: genomic engineering, pisciculture.
SUBSTANCE: the present innovation deals with induction of embryonic gynogenetic development due to inseminating ovicells with genetically inactivated sperm. Moreover, induction should be applied for ovicells of the females in the hybrids of phylogenetically distant species. Such females are able to produce unreduced diploid ovicells which are genetically identical to maternal ones. The innovation enables to create clonally reproducing female lines of sturgeon fish, (unisexual female offspring) in fish with different mechanisms of sex detection, the case when the mechanism is unknown, among them. Also, it gives the chance to considerably reduce expenses at forming a spawning school.
EFFECT: higher efficiency.
