FIELD: biotechnology; fish farming.
SUBSTANCE: invention relates to a method for producing reproductive sterile fish. Methods include immersion of unfertilized fish caviar pre-activated with water of fertilized caviar or fertilized fish caviar in immersion medium, containing antisense morpholino oligomer, which suppresses expression of dead end receptor gene in fish, which allows to produce reproductively sterile fish from caviar.
EFFECT: method of producing infertile fish and infertile aquatic animal eggs and a method of delivering compounds into caviar and embryos are proposed.
