Cold shock was applied for various durations (30, 60 and 90 min) and the ploidy levels, survival, and genotypes of the treated embryos/larvae were recorded. Analysis of ploidy levels confirmed the presence of diploid, triploid, and mosaic (1n/2n, 2n/3n, and 1n/2n/3n) genotypes in experimental groups, while it was strictly diploid in control groups. Microsatellite genotyping confirmed both the incidence of polyspermy and retention of the 2nd polar body in experimental groups. However, patterns of inheritance in all diploid offspring in experimental and control groups revealed classical Mendelian disomic inheritance. Interestingly, the observed mosaic sterlets had normal morphology and were alive. However, some larvae had abnormal morphology which may be due to haploid syndrome. In all treatment groups (treatments: 3 °C–30 min; 3 °C–60 mi...

The present paper describes the genetic characteristics of Siberian sturgeon Acipenser baerii brood stock from the Polish fish farm. The genetic analysis, based on six polymorphic microsatellite DNA analysis, revealed a high level of genetic diversity in studied broodstock of Siberian sturgeon (PIC = 0.504–0.837 and I = 1.036–2.150). The observed values of allelic richness (Ar) varied from 6.000 to 13.500 in examined fish group. Observed (Ho) and expected (He) heterozygosity across the studied loci showed values from 0.723 to 1.000 and from 0.586 to 0.857, respectively. Overall, the examined broodstock were not in Hardy-Weinberg equilibrium (H-WE), where five of the six microsatellite loci deviated from H-WE. The estimated effective population size (Ne) values by the linkage disequilibrium and the molecular coancestry methods were at the level of 47.3 (95% CI = 39.6–57.2) and 41.3 (95% CI = 3.0–128.7), respectively. A total number of 38 rare alleles within investigated microsatellite loci were found, which consisted 51% of qualitative composition of all detected alleles. All the analyzed genetic indicators suggested the good genetic condition and high genetic value of studied Siberian sturgeon farmed broodstock.
