An increase was found in the functional activity of the mechanism of osmotic and ion homeostasis in sturgeons according to the increase of the environmental salinity of a particular species.
Hypoosmotic Regulation in Anadromous Marine Sturgeon, with Special Reference to the Structure and Function of Their Kidneys and Gill Chloride Cells
Studies of osmotic and ionic regulation in ecologically diverse acipenserid fish have a bearing on understanding of the evolution of this function in ancient chondrostean ganoid fish.
Changes in sodium, calcium and magnesium ion concentrations in sturgeon (Huso huso) urine and in kidney morphology
The results suggest that the kidneys play an important part in the regulation of serum osmolarity and in the removal of Ca2+; however, in contrast to teleosts, Mg2+ must be removed extrarenally.

The neuroendocrine and endocrine systems respond to changes in the environmental salinity in a short time interval thus stimulating morphofunctional changes inThe effector organs and their transition to hypoosmotic regulation, which restores serum osmolarity close to the initial level.

Morphophysiological changes observed in the injected juveniles of Russian sturgeon Acipenser gueldenstaedtii Brandt provided the more efficient dynamics of blood serum osmolarity under saline exposure than that in the intact fish.

The immunocytochemical method with using of the complex of the protein A—colloidal gold and antibodies against ACTH for electronic-microscopical investigation was applied for the first time and the counting of the golden marks gives relative valuing of the dynamics of secretory activity in these cells during the saline influence.
