Experimental trials of acclimatization of juvenile Persian sturgeon, Acipenser persicus to different salinites of 0,5,10, 15ppt were studied. The juvenile Persian sturgeons in three weight classes (1.5, 3, 5g) have been  transfered from freshwater to different concentrations of saline water.  Na+, k+, Cl- concentrations of blood serum and the changes in the number and size o...

The aim of the present study was the genetic analysis of the Dniester population of sterlet Acipenser ruthenus and comparison of it to five other sterlet populations, in order to develop a population recovery plan. The genetic analysis of six sterlet populations from Eurasian rivers (Dniester, Dnieper, Danube, Volga, Kama and Ob) was carried out using microsatellite DNA markers. The genetic var...

Abstract Sturgeons are an economically important freshwater aquacultural fish in China and elsewhere. Research was conducted to study the magnesium requirement of juvenile hybrid sturgeon ( Acipenser schrenckii ♀ × baerii ♂) based on mineral composition, proximate chemical analysis, antioxidant enzyme levels, growth metrics. Different levels supplements (43.2, 157.3, 326.5, 549.6, 743.9, 938.4,...

Little is known of the swimming capacities of larval sturgeons, despite global population declines in many species due in part to fragmentation of their spawning and rearing habitats by man-made water-diversion structures. Larval green (Acipenser medirostris) and white sturgeon (Acipenser transmontanus) inhabit the highly altered Sacramento-San Joaquin watershed, making them logical species to ...
