Where do salmon live in the ocean?

Salmon are intensively produced in aquaculture in many parts of the world.
How many times do salmon reproduce?
Each year mature salmon make the long journey back to their natal river to reproduce, just once. For the five species of Pacific salmon (Chinook, chum, coho, pink, and sockeye), this arduous journey is a race against the clock that ends in a fleeting romance and ultimately death.
What is the survival rate of salmon?
Salmon have unusually high annual rates of mortality at sea compared with other marine fish species for which annual mortalities of 18% (M = 0.2) are frequently assumed, in contrast to the 65–95% mortality estimated for Atlantic salmon.
