Abstract: AbstractMigration is essential for the reproduction and survival of many animals, yet little is understood about its underlying molecular mechanisms. We used the salmonid Oncorhynchus mykiss to gain mechanistic insight into smoltification, which is a morphological, physiological and behavioural transition undertaken by juveniles in preparation for seaward migration. O. mykiss is experimentally tractable and displays intra‐ and interpopulation variation in migration propensity. Migratory individuals can produce nonmigratory progeny and vice ve...
