A Comparison of Neutral and Immune Genetic Variation in Atlantic Salmon, <i>Salmo salar</i> L. in Chilean Aquaculture Facilities
<div><p>Genetic diversity was assessed in samples of cultured Atlantic salmon, <i>Salmo salar</i> L., obtained from facilities in Chile between 2005 and 2010, a period of time during which the infectious pathogens Infectious Salmon Anemia (ISA) virus, <i>Caligus rogercresseyi</i> (sea lice), and <i>Piscirickettsia salmonis</i> (salmon rickettsial syndrome) were common. Two panels of microsatellite markers were utilized: one with microsatellites with no known gene associations (neutral) and one featuring microsatellites linked to putative immune-related genes (immune-related). Allelic richness and gene diversity across samples were significantly greater in neutral loci as compared to immune-related loci. Both diversity measures were homogeneous among samples for immune-related loci and heterogeneous among samples for neutral loci. Immune-related loci were identified as <i>F<sub>ST</sub></i> outliers in pairwise comparisons of samples at a 10-fold higher frequency than neutral loci. These results indicate that neutral and immune-related portions of the Atlantic salmon genome may have differed in response to the gauntlet of pathogens and that monitoring of specific, well characterized immune-related loci as well as neutral loci in cultured species could be useful when disease control and prevention is a goal.</p></div
