Description
The zope or blue bream is a slender bream relative of the family Cyprinidae reaching about 49 cm. The strongly compressed body is silvery with a blue-grey back, an upturned mouth and a notably long anal fin; this makes it resemble a slender bream, but it stays more elongate. The species lives in schools in slow-flowing rivers, lakes and river mouths of central and eastern Europe, including slightly brackish water. As an omnivore it feeds mainly on zooplankton, insect larvae and small invertebrates, partly caught in open water. In spring it spawns in shallow, vegetation-rich water. The zope is a common fish for coarse angling within its range.
