Reaction of osmoregulatory system of sterlet Acipenser ruthenus Linnaeus, 1758 (Acipenseridae) on influence of hyperosmotic medium

No functional relationship exists between the effector “organ” and the endocrine glands (interrenal and thyroid) controlled by the hormones of tropic pituitary cells, and the important role of the kidney in removing Na+ excess under hyperosmotic environment underlies the osmoconformity strategy in sterlet.


Sturgeons are commercially the most important fish species in the world. Marine animals such as fish provide Omega-3 fatty acid EPA and DHA, which are mostly promoted for their protective effects on

Welfare in the Cultured Siberian Sturgeon, Acipenser baerii Brandt: State of the Art

The chapter aims at synthesising both the knowledge and the practices that are sturgeon welfare related. This allowed the authors to outline some main lines that should be investigated to improve the

Review of the biology, fisheries, and conservation status of the Atlantic Sturgeon, Acipenser oxyrinchus oxyrinchus Mitchill, 1815

The Atlantic Sturgeon is a large member of the family Acipenseridae, historically reaching lengths of at least 4.6 m in length, and there is evidence that at least 35 North American rivers historically supported spawning populations, although only about 27 rivers are currently known or suspected to support spawning populations.

Reaction of osmoregulatory system in juveniles of Russian sturgeon Acipenser gueldenstaedtii (Acipenseridae) on influence of comatotropin of carp Cyprinus carpio

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.

Morphofunctional remodelling of the osmoregulatory system in starred sturgeon Acipenser stellatus (Acipenseridae) during transition from hyperosmotic to hypoosmotic regulation

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.

Oxygen consumption and haematology of juvenile shortnose sturgeon Acipenser brevirostrum during an acute 24 h saltwater challenge.

Results imply an inability of juvenile A. brevirostrum to regulate water and ions in full-strength seawater within 24 h, but no mortality occurred in any exposure, suggesting that juveniles exposed to full- strength seawater can tolerate short periods in saline environments.

Effects of Dietary Garlic Powder on Growth, Feed Utilization and Whole Body Composition Changes in Fingerling Sterlet Sturgeon, Acipenser ruthenus

It is suggested that dietary GP for fingerling sterlet sturgeon could positively affect growth performance and protein retention.

Fish-Breeding and Biological Results of Spawning Campaign for Beluga Reproduction

The article presents the fish-breeding and biological results of spawning campaign for artificial reproduction of beluga, and a comparative analysis of individual reproductive parameters of domesticated female beluga has been carried out.
