Oncorhynchus - Range

Range

Salmon and trout with ranges generally in waters draining to the Pacific Ocean are members of the genus. Their range extends from Beringia southwards, roughly to Japan in the west and Mexico to the east. In North America, some subspecies of O. clarki are native to the landlocked Great Basin, while others are native to the Rio Grande and western tributaries of the Mississippi River Basin which drain to the Gulf of Mexico, rather than to the Pacific.

Unlike many trout species of the mainly European genus Salmo, many Oncorhynchus are anadromous (migratory) and semelparous (die after spawning). Some species of char (Salvelinus genus) are native to Pacific waters and are also referred to as trout.

Famous quotes containing the word range:

    Culture is the suggestion, from certain best thoughts, that a man has a range of affinities through which he can modulate the violence of any master-tones that have a droning preponderance in his scale, and succor him against himself. Culture redresses this imbalance, puts him among equals and superiors, revives the delicious sense of sympathy, and warns him of the dangers of solitude and repulsion.
    Ralph Waldo Emerson (1803–1882)

    The ideal of the self-sufficient American family is a myth, dangerous because most families, especially affluent families, do in fact make use of a range of services to survive. Families needing one or another kind of help are not morally deficient; most families do need assistance at one time or another.
    Joseph Featherstone (20th century)

    Jane Addams, founder of Hull House, once asked, “How shall we respond to the dreams of youth?” It is a dazzling and elegant question, a question that demands an answer—a range of answers, really, spiraling outward in widening circles.
    William Ayers, U.S. author. To Teach: The Journey of a Teacher, ch. 7 (1993)
