Abstract⎯Genetic variation of aquaculture broodstocks of the Siberian sturgeon of different origin from 13
farms across the Russian Federation was assessed at five tetraploid microsatellite loci and the mitochondrial
DNA control region. At present, in aquaculture stocks of Siberian sturgeon originating from the Lena and Ob
rivers, a sharp decline of haplotype diversity is observed. The most part of aquaculture individuals carry two
major haplotypes characteristic of the European part of Russia (the Lena aquaculture) and two haplotypes
characteristic of the western part of Siberia (the Ob aquaculture). According to the results of the microsatellite
analysis, in sturgeon aquaculture stock originating from the Lena River, two genetic clusters can be distin-
guished. One of these clusters is represented by the stocks composed of inbred individuals and, because of
this, is characterized by depleted allelic variation and the loss of rare alleles.

The Siberian sturgeon Acipenser baerii Brandt is
the first sturgeon species introduced into intensive
commercial aquaculture, and to this day, it remains
the most important species grown in artificial condi-
tions both in Russia and in other countries [1, 2].
Introduction into aquaculture began in 1973, when for
the first time 61000 fertilized eggs were obtained from
wild broodstock from the Lena River and transported
to Konakovo, an experimental warm-water fish farm
in Tver oblast near Moscow. The deliveries of fertilized
eggs to Konakovo continued in the following years .
In Konakovo, using this species, the techniques for
keeping, feeding, obtaining eggs, and growing juve-
niles under completely artificial conditions were
Breeding of Siberian sturgeon has become most
popular in the European part of Russia owing to its
high ecological plasticity and the great potential for
growth and, accordingly, the maturation rate upon
entering favorable environmental conditions in warm-
water sturgeon farms. Until the end of the last century,
the Siberian sturgeon in aquaculture was represented
almost exclusively by the Lena population, which
originated from the broodstock of the Konakovo stur-
geon farm (SF).
In 1980, some of the sturgeons (300 larvae) were
sent to France, where the aquaculture of the Siberian
(Lena) sturgeon also began to develop successfully .
The vast majority of aquaculture stocks of the Siberian
sturgeon now existing around the world also originate
from the progeny of a limited number of sturgeons
from the Lena River, bred at Konakovo SF .
Recently, a number of aquaculture farms in western
Siberia, in the conditions of aquaculture, began to rear
sturgeon, the broodstock of which originated from the
Ob River and its tributaries. In 1999, a stock of the Ob–
Irtysh Siberian sturgeon was also created in Konakovo,
using stocking material from the Abalakskii SF .
In this study, we do not formulate the problem of
studying individual aquaculture stocks of the Siberian
sturgeon belonging to different sturgeon farms. Using
a set of samples from a large number of modern aqua-
culture farms, we tried to reflect the situation as a
whole, to study the genetic consequences of domesti-
cation of the Siberian sturgeon, the most popular species
in aquaculture of sturgeons over the last 30–40 years,
since the beginning of intensive development of stur-
geon farming in Russia.
