单词	cisco
释义	cisco /ˈsɪskəʊ / noun (plural ciscoes) A freshwater whitefish of northern countries, most species of which are important food fishes. Genus Coregonus, family Salmonidae: several species. They prey on such fish as the cisco (lake herring), lake whitefish, central mudminnow, and golden shiner.... Overfishing of other species of ciscoes has reduced populations, and shifted more pressure to Coregonus hoyi. Coregonine fishes in New York, both whitefish and cisco, have been extensively introduced into waters outside of their natural ranges, such as lakes in the Adirondack Mountains. Origin Mid 19th century: of unknown origin.
