The use of microsatellite DNA loci for genetic monitoring of Atlantic salmon populations
This work addresses the application of a new group of molecular markers, microsatellite loci, to monitor genetic diversity in stocks used in fish enhancement programs. To illustrate the potential use of these markers, we examined the genetic variation associated with the Connecticut River and Penobs...
