Description

The largefin bitterling is a cyprinid from East Asia, native to China, Korea, northern Vietnam and southeastern Russia (Amur); introduced in Japan. The species reaches about 27 cm and has a deep, compressed, silvery body. It inhabits slow-flowing and standing waters. Like other bitterlings the species reproduces with the help of living freshwater mussels: the female uses a long ovipositor to lay the eggs among the gills of a mussel, where the young grow up sheltered. This creates a close ecological link between the fish and the mussel. The sexes differ mainly in colour and shape during the breeding season.
