Every year, countless juvenile Pacific salmon leave streams andrivers on their migration to feeding grounds in the North Pacific Oceanand the Bering Sea. After periods ranging from a few months to severalyears, adult salmon enter rivers along the coasts of Asia and NorthAmerica to spawn and complete their life cycle. Within this generaloutline, various life history patterns, both among and within species,involve diverse ways of exploiting freshwater, estuarine, and marinehabitats. There are seven species of Pacific salmon. Five (coho,chinook chum, pink, and sockeye) occur in both North America and Asia.Their complex life histories and spectacular migrations have longfascinated biologists and amateurs alike.
