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:
“Although Samuel had a depraved imagination—perhaps even because of this—love, for him, was less a matter of the senses than of the intellect. It was, above all, admiration and appetite for beauty; he considered reproduction a flaw of love, and pregnancy a form of insanity. He wrote on one occasion: “Angels are hermaphrodite and sterile.””
—Charles Baudelaire (1821–1867)
“Were I called on to define, very briefly, the term Art, I should call it “the reproduction of what the Senses perceive in Nature through the veil of the soul.” The mere imitation, however accurate, of what is in Nature, entitles no man to the sacred name of “Artist.””
—Edgar Allan Poe (1809–1845)
“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)
