Abstract
The sterlet (Acipenser ruthenus) is one of the 27 sturgeon species and is well-known for its wide distribution and small body size in comparison to other sturgeons. For assessing the population genetics and parentage identification of sterlet, ten microsatellites developed for Chinese sturgeon and cross-amplified in sterlet were tested by 40 individuals of sterlet. The ten microsatellites were developed using transcriptome sequencing of Chinese sturgeon. The expected heterozygosity (H(E)), observed heterozygosity (H(O)), Shannon-Weiner diversity indices (H') and polymorphic information content (PIC) of the 10 microsatellites ranged from 0.466 to 0.751, from 0.438 to 0.938, from 0.66 to 1.51 and from 0.368 to 0.716, respectively. Combined exclusion probability based on the genotype of pair parent known (CE-PP), one parent known (CE-2P), and no parent known (CE-1P) of the 10 microsatellites were 99.99%, 99.96%, and 99.49%, respectively. These result showed that the 10 microsatellites should be helpful for assessing the population genetics and parentage identification of sterlet.
