People Touring Nimbus Fish Hatchery

Each year, Chinook salmon and Steelhead trout journey upriver in one of nature’s most awe-inspiring events. After two to four years, these migratory fish use their keen sense of smell to guide them back from the ocean to the gravel beds and hatcheries where they hatched from eggs several years before. Most mature salmon enter the American River in the fall, followed by steelhead in the winter.

Salmon undergo several dramatic physical changes during their upstream journey. Their skin changes from bright silver to dark gray or red, their reproductive organs develop, their digestive system shrinks, and the male develops a hooked jaw. Although salmon will strike various lures and baits, they are no longer able to digest food, so they survive by using their stored body fat. They die shortly after spawning. Steelhead continue to feed during their upriver journey and may return to spawn several times in their life. The above text is from California Department of Fish & Game Web site.
