Analysis of correlation between body length and genetic polymorphism for Loci ESTD-1 and IDHP-3 in the Atlantic salmon Salmo salar

摘要

Correlation between the body length and characteristics of genetic polymorphism for loci Me-2, IDHP-3, ESTD-1, and AAT was studied in the Atlantic salmon, Salmo salar. The study was based on the data on genetic variation in more than 4000 fish grownat the Kandalaksha Hatchery. Of the 4 loci studied, ESTD-1 and IDHP-3 were distinguished since they could be considered as body length markers in the Atlantic salmon. Analysis of mean locus heterozygosity indicated a disturbance in the mechanism of negative heterosis that is characteristic of natural populations. This presumably reflected a change in the genetic diversity of the Atlantic salmon under the influence of breeding.
