“…Within its area of occurrence there are two sub-species: the Atlantic sturgeon, Acipenser oxyrinchus oxyrinchus, from the north, and the Gulf sturgeon, Acipenser oxyrinchus desotoi, from the south (Kolman et al 2008a). Genetic testing has provided evidence that the Atlantic sturgeon also inhabited the waters of Europe (Ludwig et al 2002, Stankoviè et al 2007, Desse-Berset 2009, and currently, the sub-species Acipenser oxyrinchus oxyrinchus is being restored to the Baltic Sea (Gessner et al 2005, Kolman et al 2008a). Re-establishing the sturgeon population requires the production of stocking material that can be released into rivers.…”

Abstract. The impact of stocking density on the growth, feed conversion, oxygen consumption, and ammonia excretion of juvenile Atlantic sturgeon (Acipenser oxyrinchus Mitchill) was studied. Three initial stocking densities were used in the experiment: 1.27, 2.49, and 3.80 kg m -2 . The length of the experiment was 64 days. The mean water temperature was 15.0°C. The fish were fed commercial feed Nutra T 1.9 (Trouv, France). Atlantic sturgeon body weight growth was the highest in the group stocked at the lowest density. The fish from this group attained a final body weight of 130.1 g, which was statistically significantly higher than that of the groups stocked at densities of 2.49 kg m -2 (P < 0.05) or 3.80 kg m -2 (P > 0.01).Stocking density had a substantial impact on the value of the feed conversion ratio (FCR) in the different groups. The lowest FCR was noted at the density of 1.27 kg m -2 at 0.67. This value differed statistically significantly from group 2.49 kg m -2 , in which it was 0.74 (P < 0.05), and it differed highly statistically significantly from group 3.80 kg m -2 at 0.83 (P < 0.001). The differences in the FCR value between groups 2.49 and 3.80 kg m -2 were also highly statistically significant.

“…In addition to the Atlantic coast of North America, this species until recently has populated the Baltic Sea and the rivers that flow into it (Ludwig et al, 2002). In recent years, programs for the restitution of Atlantic sturgeon have been initiated in the Baltic region (Gessner et al, 2011;Gushchin et al, 2013;Kolman, Kapusta, Duda, & Wiszniewski, 2011). It requires research to improve the technology of fish fry obtaining.…”

Successful breeding of fish species in aquaculture depends on several factors, among which the temperature and feed are the most significant ones. This study was designed to evaluate the effect of temperature in the range of 14–18°C on the rate of embryogenesis and duration of larva period and to estimate the efficiency of Artemia nauplii enriched with PUFAs in growing sturgeon larvae. The temperature of 16°C is the most suitable for both egg incubation and Atlantic sturgeon prelarvae maintenance under aquaculture conditions. Even minor temperature fluctuations of 1 degree up or down leads to increased loss both of eggs and prelarvae. Increased temperature shortens the incubation period but has a lesser impact on the duration of prelarvae onset of external feeding. The technology of Artemia nauplii bioencapsulation with a PUFA‐containing supplement in A. oxyrinchus rearing increases sturgeon larvae weight by 1.5 times at a constant survival dynamic.

“…Baltic sturgeon ( Acipenser oxyrinchus ), is currently considered extinct or missing in the range countries to the Baltic Sea. In order to recover Baltic sturgeon populations, restoration programs have been initiated in an attempt to establish self-sustaining populations and thus to safeguard the long-term viability of the species (Gessner et al, 2011).…”

Conservation biologists have long emphasized the importance of environmental enrichment in hatcheries which main objective is restocking. In this study, we evaluated the impact that long-term exposure of environmental enrichment in an artificial river section (surface water, ambient light and temperature) has on neural plasticity in juvenile Baltic sturgeons (Acipenser oxyrinchus) in comparison to fish that were reared in glass-fiber tanks in a recirculation system (aquaculture control group) under constant light and temperature conditions and an intermediate group reared in glass-fiber tanks with ambient water and natural photoperiod and temperature fluctuation. All expositions were carried out in triplicate. From the three markers reported to indicate neural plasticity, only an up-regulation of neurod1 in the forebrain of Baltic sturgeon (A. oxyrinchus) reared in enriched environment was observed in comparison to the semi-natural group and to the aquaculture (control) group. The two other markers (brain-derived neurotropic factor (bdnf), and proliferating cell nuclear antigen (pcna) did not reveal any significant differences between the groups. In conclusion, only minor effects of environmental enrichment on neuroplasticity were observed here.
