“…Mutations and null alleles in microsatellites are a common phenomenon resulting in failed assignments (Ellegren, 2000). The mean mutation rate obtained in our study (10 -2 per locus per generation) is higher than other fish species, such as the carp Cyprinus carpio with 10 -4 (Yue et al, 2007), or various salmonids with 10 -2 -10 -5 (Shaikhaev & Zhivotovsky, 2014). Despite the high mutation rate, five high-variable microsatellites were enough to confidently determine, by direct exclusion, the parentage of progeny from a relatively small broodstock of the spotted rose snapper.…”

The spotted rose snapper Lutjanus guttatus is a fishery relevant species from the eastern Pacific Ocean, with aquaculture potential. Species-specific genetic markers are needed for the genetic characterization of wild and cultivated populations to help management strategies. Eighteen hypervariable microsatellites were developed by Next Generation Sequencing and characterized in a wild population sample. Genetic diversity was high (observed heterozygosity = 0.88 ± 0.050; the number of alleles per locus = 13.4 ± 1.3) and few loci departed from the Hardy-Weinberg Equilibrium, leaving 14 loci potentially suitable for population genetic studies. A reduced panel of five loci was tested in a cultivated stock to determine the parentage of progeny (embryonated eggs; n = 413), to estimate the temporal contribution of each parental broodstock. The above resulted in the successful assignment of 95.6% of the progeny to its parental couple, representing 17 out of the 24 possible families. Two of the four females produced most of those progeny (97.3%). These females, which reproduced throughout the season, did not spawn on consecutive days. The contribution of males was evenly distributed during the season and occurred on successive days. Some microsatellites can be used in other lutjanids (L. peru, L. argentiventris, and Hoplopagrus guentherii).

“…Polymor phism in the number of 13 nucleotide repeats is observed only in chum salmon and pink salmon. In sockeye salmon, this sequence is also present but in a single copy, while it is absent in all other salmon spe cies, including those close to this triad, coho salmon and chinook salmon [31]. In the Mid Pleistocene, during the Pliocene Pleis tocene glaciation and marine regressions, subspecies formed and numerous populations occupying the niches of the Pacific freshwater basins and ocean resources appeared [5].…”

This review discusses genetic approaches to solving important problems of evolutionary biology of salmonid fishes with special reference to Pacific salmon and trout. The problems of the genetic phylogeny of salmonid fishes, including issues of the consistency/inconsistency of phylogenetic tree topologies built using genetic and phenotypic characteristics, the timing of the main phylogenetic events, the relationships among different taxa, including the mutual status of Pacific salmon and trout, and others are discussed. The problems of the tetraploidization of the salmonid fishes, as well as the dilemma of their freshwater/marine origin, and the semelparity of some of the species are reviewed.

“…Therefore, microsatellites have become the marker of choice for gene studies and genome evolution for all taxa. Many studies have examined the genetics of salmonid fishes using microsatellite markers in recent years (Kordichevaet al, 2010;Khrustaleva, Volkov, Stocklitskaya, Mugue, & Zelenina, 2010;Afanasiev, Rubtsova, Shitova, Shaĭkhaev, & Zhivotovskii, 2011;Shaikhaev & Zhivotovsky, 2014;Rubtsovaet al, 2016); however, many microsatellite sequences in GenBank for T. arcticus grubei are still unknown. We must screen for more polymorphic microsatellite markers in T. arcticus grubei in order to improve fine-scale population structure, stock management and enhancement, genetic linkage map construction, and molecular marker-assisted breeding.…”

The population of Xinjiang arctic graylings (Thymallus arcticus grubei) has dramatically declined in China. A total of 22 polymorphic microsatellite loci were isolated and characterized from AFLP products in the Xinjiang arctic grayling. The number of alleles (Na) per locus varied from 3 to 13. Observed (HO) and expected (HE) heterozygosities ranged from 0.60 to 0.97, and from 0.58 to 0.89, respectively. These new microsatellite markers are a helpful tool for genetic analyses, stock management, and resource conservation efforts for T. arcticus grubei. According to the total number of alleles, the total effective number of alleles, and the total number of genotypes, the Fuhai population showed the highest diversity among all the populations while the Fuyun sample was the lowest. Five additional fish species: Red seam bream (Pagrus major), Lenok (Brachymystax lenok), Sea perch (Lateolabrax japonicus), Taimen (Hucho taimen), and Amur grayling (Thymallus grubii) were assessed for cross-species amplification. Three out of the five species showed at least two polymorphic loci. In addition, six loci were found to be polymorphic in at least one species.
