Development of Microsatellite Loci in Eulachon (Thaleichthys pacificus)

The decline of eulachon spawning runs over the past decade has enhanced the need for management units that reflect the genetic structure of the species. We report the development of 14 novel, highly polymorphic di‐ and tetranucleotide loci for use in population studies. In a survey of over 200 individuals from two rivers from the Pacific NW, observed heterozygosities of the loci ranged from 0.54 to 0.95 and an average of 23 alleles per locus were resolved. All 14 microsatellite markers were in Hardy–Weinberg equilibrium.
