Oncorhynchus kisutch

 

The silver salmon is a medium-sized Pacific salmon, averaging between 7 and 12 lbs (3-5 kg), although some have been known to reach up to 30 lbs (14 kg). Like most other Pacific salmon, the time between hatching, migrating to the ocean, and finally returning to freshwater to spawn and die depends on the individual.

   Unlike most Pacific salmon, the silver may stay in freshwater as a small juvenile fish, also called fry, for several years before starting the journey to the ocean. Once in the ocean, they typically spend a year and a half feeding in the rich marine waters before returning to their natal stream.
