Description

The rudd is a deep-bodied, golden-sheened freshwater fish of the family Cyprinidae reaching about 50 cm but usually smaller. It resembles the roach but has a more upturned mouth, bright orange-red fins and a dorsal fin that starts clearly behind the base of the pelvic fins. The species lives in vegetation-rich lakes, ponds, ditches and slow rivers of Europe and western Asia, often just below the surface among water plants. As an omnivore it feeds on water plants, algae, insects and zooplankton. In late spring it spawns in shallow, vegetation-rich water. The rudd is a much-caught fish for angling and a common sight in inland waters.
