Isolation of polymorphic microsatellite markers for the demersal fish Helicolenus dactylopterus (Dela Roche 1809)

Six microsatellite loci were identified for the demersal deep-sea fish Helicolenus dactylopterus. All loci were highly polymorphic (5-21 alleles per locus). Observed heterozygosities were from 0.378 to 0.868, while the expected heterozygosities ranged from 0.529 to 0.925. Multiplex PCR reactions were optimized. Microsatellite markers were developed for analysis of genetic structure including identification of stocks and migration patterns. The resulting data Will be used to help in the establishment of scientifically based fisheries management for this species. Departures from the expected Hardy-Weinberg equilibrium were observed in three loci, and are likely to be a consequence of population structuring across the Azorean islands.
