Bream (Abramis brama)
The bream is one of the largest freshwater representatives of the carp family. It does not like water currents, and with relatively little oxygen requirements it sticks to places with a lazy stream and muddy bottom. It lives in schools, thus protecting itself from predators. Its flattened and compact body shape is the reason for the ease with which it moves in the reeds and among seaweed. The bream usually feeds on small animals at the bottom, and hunting for them it digs in the muddy bottom, leaving traces in the form of funnel-shaped grooves.
It reproduces easily creating large populations that dwarf when the food supply is insufficient because they are forced to compete for food with other members of the carp family.
