Diet
Crappies feed early in the morning and from about midnight until approximately 2am. Individuals smaller than about 16 cm in length eat plankton and minuscule crustaceans, while larger individuals feed on small fishes (like shad), as well as minnows. Adult black crappie feed on fewer fish than white crappie do; instead they consume a larger volume of insects and crustaceans. According to scientific studies carried out in California, mysid shrimp, Neomysis awatschensis, as well as amphipods, and Corophium, were the most commonly eaten by all sizes of black crappie. Although this diet is popular among black crappies in general, their diet may significantly change based on habitat, availability of food, and other biotic factors such as amount of resource competition. The same study also showed that young, small crappie tend to feed on small aquatic invertebrate animals and changed to a fish-filled diet as they matured to adulthood. Its diet, as an adult, tends to be less dominated by other fish than that of the white crappie.

Famous quotes containing the word diet:
“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)
“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)
“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)
