Captive rearing effects on the methylome of Atlantic salmon after oceanic migration: Sex‐specificity and intergenerational stability

Molecular Ecology Resources, EarlyView., 2023
Abstract Captive rearing in salmon hatcheries can have considerable impacts on both fish phenotype and fitness within a single generation, even in the absence of genetic change. Evidence for hatchery‐induced changes in DNA methylation is becoming abundant, though questions remain on the sex‐specificity of these effects, their persistence until spawning
