Vitellogenin Level in the Plasma of Russian Sturgeon (Acipenser gueldenstaedtii) Northern Israel

Journal of Marine Science: Research & Development, 2017
In the present study, we examined the vitellogenin (Vg) level of Russian sturgeon maintained in a relatively constant aquaculture at a water temperature of 18-22°C during growth and maturation. An increase in Vg in the blood plasma from oocytes was found in the yellow oocytes stage to the gray oocytes stage.
