Reproduction
Sockeye are blue tinged with silver in color while living in the ocean.
Sockeye spawn mostly in streams whose watersheds include a lake. The young fish, known as fry, spend up to three years in the freshwater lake before migrating to the ocean. Some stay in the lake and do not migrate. Migratory fish spend from one to four years in salt water, and thus are four to six years old when they return to spawn between July and August. Navigation to the home river is thought to be done using the characteristic smell of the stream, and possibly the sun.
Some fish spend as long as four years in fresh water lakes before migrating. In rivers without lakes, many of the young move to the ocean soon after hatching. These salmon mature after one to four years in the ocean.

Famous quotes containing the word reproduction:
“An original is a creation
motivated by desire.
Any reproduction of an original
is motivated by necessity ...
It is marvelous that we are
the only species that creates
gratuitous forms.
To create is divine, to reproduce
is human.”
—Man Ray (1890–1976)
“As the twentieth century ends, commerce and culture are coming closer together. The distinction between life and art has been eroded by fifty years of enhanced communications, ever-improving reproduction technologies and increasing wealth.”
—Stephen Bayley (b. 1951)
“It is so characteristic, that just when the mechanics of reproduction are so vastly improved, there are fewer and fewer people who know how the music should be played.”
—Ludwig Wittgenstein (1889–1951)
