Where does California's salmon come from?

California's salmon primarily come from the state's rivers and streams, particularly the Sacramento and San Joaquin River systems. These waterways serve as critical habitats for several salmon species, including Chinook, coho, and steelhead. Many salmon also originate from hatcheries that support both wild populations and commercial fishing. Additionally, some salmon migrate from the Pacific Ocean back to their spawning grounds in California's freshwater systems.
