Expression of the dmrt1 and vtg genes was described using the real‐time PCR (rt‐PCR) method from 25 to 1600 days post‐hatch (dph) in cultured Russian sturgeon Acipenser gueldenstaedtii . The level of dmrt1 transcription in gonads in subsequent studied periods increased exponentially while vtg expression increased in gonads and livers of A. gueldenstaedtii examined, but in later stages of development. Both dmrt1 and vtg genes showed elevated expression in intersex individuals probably caused by dietary exposure to phyto‐oestrogens.
