- Family: Carps and minnows – Cyprinidae
- Similar species: bream (common), white bream
- Size: 25–35 cm, seldom 40 cm.
- Appearance: Unlike its cousins the common bream and white bream, the blue bream is a plankton feeder found close to the surface. This can be seen from the shape, which is more streamlined and the mouth clearly upturned. The blue bream is less deep in the body and noticeably more flattened, particularly around the tail. With 37–46 rays, the anal fin is the longest of any Finnish cyprinid. The scales are small, numbering 67–75 along the lateral line.
- Colouring: Generally pale with silvery sides. Fins pale yellow to colourless.
- Reproduction: Spawns in shallow reedy bays once the ice has melted.
- Food: Mainly plankton.
- Distribution and habitat: Blue bream are found in a number of lakes in southern Finland, not widespread. It is one of the few freshwater species not found in the Baltic Sea. It favours nutrient-rich waters. Young blue bream inhabit weedy lake margins but older fish move into open water in search of plankton.
