Abstract
A total of 32 nuclear-encoded microsatellites, including 15 polymorphic and 13 monomorphic microsatellites, isolated from an enriched genomic library of the triakid shark, Mustelus canis (dusky smoothhound), and four microsatellites previously isolated from two other triakid sharks were characterized in 91 individuals of M. canis. Polymorphic repeat motifs included 12 dinucleotide, two trinucleotide and one pentanucleotide repeat(s). Mustelus canis supports both commercial and recreational fisheries throughout its range in the western Atlantic Ocean from Maine (USA) to southern Argentina. The microsatellites characterized will be useful in studies of population structure of M. canis and other triakid sharks.
