The Alaska Region of the U.S. Fish & Wildlife Service and the Fairbanks Fish & Wildlife Field Office,
welcome you to Cyber Salmon! At this web site, you can learn great things about chum, chinook, pink, sockeye, and coho
salmon, the five Pacific salmon species found in the Yukon River drainage. Explore farther to discover what we're learning
about these fish.
People: Fisheries have some significance to every
community in Alaska. Fish may serve as an important subsistence food source, provide a variety
of jobs, or offer recreational opportunities.
Fish: Salmon are a vital part of food chains in all the habitats they occupy throughout their lives. Eggs
and juvenile fish are an important food source in the streams where they hatch. Smolts in
estuaries and adults in the ocean are a component of marine food chains. Spawning salmon carry ocean
nutrients back to the streams where they are released when the fish die and decay. These
nutrients feed insects and fertilize plants that will provide food and cover for the salmon that
hatch next spring.
Habitat: Salmon occupy many different habitats throughout their lives. Cold, clear streams, quiet pools,
lakes, major rivers; estuaries, and the open ocean are all habitats for salmon at some point in their life
cycle. All of these habitats must remain healthy in order to ensure the survival of the species.
