Carassius cuvieri
A tall-bodied crucian originally from Japan's Lake Biwa, widely introduced to Korean reservoirs where it grows larger than the native crucian. It filter-feeds on plankton in midwater, making it a distinct float-fishing challenge. Suspended dough baits fished at precise depths with sensitive floats are the technique.
0 – 10 m
Suspended dough bait (tteokbap) fished at a precise depth under a highly sensitive float; the fish feeds in mid-water on plankton so the bait must be suspended, not on the bottom.
Rarely eaten; primarily a sport-fishing target requiring refined float-fishing technique, usually released after being caught.
Native crucian carp (붕어, Carassius carassius) is noticeably shorter-bodied and more golden-brown; Japanese crucian carp has a uniquely tall, slab-sided body.
