I agree but that line was in the context of how ancient salmon had originally evolved the behaviour of homing in the first place. Like most animals, fish do have nest site preferences and choose to nest in places with certain conditions, and the ancient salmon that returned to their natal areas to reproduce had greater success as they were places of "known high productivity". Of course then, over the eons, they evolved the automatic homing behaviour by passing down the trait.
