Heritability estimation via molecular pedigree reconstruction in a wild fish population reveals substantial evolutionary potential for sea-age at maturity, but not size within age-classes
While evolutionary responses require heritable variation, estimates of heritability h from wild fish populations remain rare. A 20-year molecular pedigree for a wild Scottish population of Atlantic salmon (Salmo salar) was used to investigate genetic contributions to (co)variation in two important,...

While evolutionary responses require heritable variation, estimates of heritability h from wild fish populations remain rare.

Sea-age was strongly heritable h = 0.51) and size exhibited moderate heritability h = 0.27). A very strong genetic correlation G = 0.96) between these traits implied the same functional loci must underpin variation in each. Indeed, body size within sea-ages had much lower heritability that did not differ significantly from zero. Thus, within wild S. salar populations, temporal changes in sea-age composition could reflect evolutionary responses, whereas rapid changes of body-size within sea-ages are more likely due to phenotypic plasticity.
