Assessing introgression of foreign strains in wild Atlantic salmon populations: variation in microsatellites assessed in historic scale collections

摘要: 1. Genetic variation at five microsatellite loci was analysed in a collection of scales (1970–97) sampled from Atlantic salmon adults returning to the Nivelle River (South France). 2. Native and foreign fish (from an allochthonous Scottish stock introduced into river increase population size) were clearly identified as all individuals released physically marked. 3. Introgression genes native gene pool has occurred, although reproductive success wild lower than that individuals. 4. The utility old scale samples for investigating impact stocking on populations is demonstrated this work.
