Diet
Sockeye salmon, unlike other species of Pacific salmon, feed extensively on zooplankton during both freshwater and saltwater life stages. Their numerous gill rakers strain the plankton from the water. This diet may be the reason for the striking hue of their flesh, as well as their very low concentration of methylmercury. They also tend to feed on small aquatic organisms such as shrimp. Insects are part their diets at the juvenile stage.

Famous quotes containing the word diet:
“Newsmen believe that news is a tacitly acknowledged fourth branch of the federal system. This is why most news about government sounds as if it were federally mandated—serious, bulky and blandly worthwhile, like a high-fiber diet set in type.”
—P.J. (Patrick Jake)
“I learned from my two years’ experience that it would cost incredibly little trouble to obtain one’s necessary food, even in this latitude; that a man may use as simple a diet as the animals, and yet retain health and strength.... Yet men have come to such a pass that they frequently starve, not for want of necessaries, but for want of luxuries.”
—Henry David Thoreau (1817–1862)
“Television programming for children need not be saccharine or insipid in order to give to violence its proper balance in the scheme of things.... But as an endless diet for the sake of excitement and sensation in stories whose plots are vehicles for killing and torture and little more, it is not healthy for young children. Unfamiliar as yet with the full story of human response, they are being misled when they are offered perversion before they have fully learned what is sound.”
—Dorothy H. Cohen (20th century)
