Three hatchery origins were simulated, Bergerac (BG) with F0 parents, Castels (CS) and Pont-Crouzet-Cauterêts (PCC) from F1 parents, using the real genotypes of hatchery parents and the recorded mating plans. Wild-born individuals were simulated from non-hatchery parents. Real captured returning individuals from each salmon run were assigned with the same set of potential parents.
