Feeding
Rainbow trout are predators with a varied diet, and will eat nearly anything they can grab. Their image as selective eaters is only a legend. Rainbows are not quite as piscivorous or aggressive as brown trout or lake trout (char). Young rainbows survive on insects, fish eggs, and smaller fish (up to 1/3 of their length), along with crayfish and other crustaceans. As they grow, though, the proportion of fish increases in most all populations. Some lake-dwelling lines may become planktonic feeders. While in flowing waters populated with salmonids, trout eat varied fish eggs, including salmon and cutthroat trout, as well as the eggs of other rainbow trout, alevin, fry, smolt and even leftover carcasses.

Famous quotes containing the word feeding:
“I am still a learner, not a teacher, feeding somewhat omnivorously, browsing both stalk and leaves; but I shall perhaps be enabled to speak with more precision and authority by and by,—if philosophy and sentiment are not buried under a multitude of details.”
—Henry David Thoreau (1817–1862)
“It no longer makes sense to speak of “feeding problems” or “sleep problems” or “negative behavior” is if they were distinct categories, but to speak of “problems of development” and to search for the meaning of feeding and sleep disturbances or behavior disorders in the developmental phase which has produced them.”
—Selma H. Fraiberg (20th century)
“When all who had money and leisure
Grew rural o’er ices and wines,
All pleasantly toiling for pleasure,
All hungrily pining for pines,
And making of beautiful speeches,
And marring of beautiful shows,
And feeding on delicate peaches,
And treading on delicate toes.”
—Winthrop Mackworth Praed (1802–1839)
