The Roach has a slivery appearance with reddish fins. It can be distinguished from the Rudd (Scardinius erythropthalmus) by the leading edge of its dorsal fin, which is inline with the leading edge of its ventral fins.
Roach spawns in shoals on submerged vegetation from April to early June, depending on conditions. It is omnivorous and feeds on zooplankton, zoobenthos, detritus, epiphytes, phytoplankton, and macrophytes.
Seen all year round, it is found in lakes, rivers and canals. Common and widespread throughout Britain. A native species.
