[Analysis of correlation between body length and genetic polymorphism for loci ESTD-1 and IDHP-3 in the Atlantic salmon Salmo salar].
Correlation between body length and characteristics of genetic polymorphism for loci Me-2, IDHP-3, ESTD-1, and AAT-2 were studied in the Atlantic salmon Salmo salar. The study was based on data on genetic variation in more than 4000 fish grown at the Kandalaksha Hatchery. Of four loci studied, loci ESTD-1 and IDHP-3 were distinguished by the fact that they can be confidently considered body-length markers in the Atlantic salmon. Analysis of mean locus heterozygosity indicates a disturbance of the mechanism of negative heterosis that is characteristic of natural populations. This presumably reflects a change in the genetic diversity of the Atlantic salmon under the influence of breeding.
