Freshwater bream (Abramis brama) fish species information

Scientific Name
Abramis brama

Common Name
Freshwater bream

Biology
Inhabit a wide variety of lakes and large to medium sized rivers. Most abundant in backwaters, lower parts of slow-flowing rivers, brackish estuaries and warm and shallow lakes (Ref. 59043). Adults occur usually in still and slow-running waters where they travel in large shoals (Ref. 9696). Larvae and juveniles live in still water bodies, feeding on plankton. One to two years old juveniles move from backwaters to river to feed. In the absence of opportunity to leave backwaters, juveniles may adapt but have a slower growth and attain maturity at a smaller size. They also drift to brackishwater estuaries to forage when water level of flooded areas drops in lower reaches of large rivers. Foraging juveniles in brackish waters stay in lower parts of rivers to overwinter in freshwater (Ref. 59043). Feed on insects, particularly chironomids, small crustaceans, moll
