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.

Molecular cloning and expression dynamics of Atrogin-1 in muscle tissue of Russian sturgeon (Acipenser gueldenstaedtii) under high salt stress

Aquaculture Reports
Atrogin-1, a muscle-specific ubiquitin ligase, is integral to the regulation of protein degradation and plays a pivotal role in the targeted degradation of critical muscle signaling proteins, which can lead to skeletal muscle dysfunction.
