- Abstract
Chaeturichthys stigmatias Richardson, 1844, a fish species of the family Gobiidae, is an offshore warm-temperate fish species and a dominant component of estuarine ecosystems. In this study, restriction site-associated DNA sequencing was adopted to analyze the traits of candidate microsatellite markers for C. stigmatias, and 30 polymorphic loci were developed. A total of 5631 microsatellites with primer fragments were detected, among which trinucleotide repeats (57.56% of the total simple sequence repeats) were the most abundant, followed by di- (23.30%), tetra- (11.79%), penta- (4.14%), and hexa- (3.21%) nucleotide repeats type. The numbers of alleles per locus ranged from 6 to 14 with the mean value of 10.4. The mean value of observed heterozygosity and the expected heterozygosity were 0.349 and 0.870, respectively. The microsatellite locus with the lowest polymorphic information content (PIC) was 0.749, which indicated that all sites were highly polymorphic (PIC > 0.50). This is the first microsatellite development and characterization of this species to be reported.
