Black Carp
Mylopharyngodon piceus
The darkest of China's four great carps, the black carp is a snail-crushing giant that escaped fish farms into the lower Mississippi. A rare, powerful and strictly controlled catch.
Seasons · Peak
Identifying features
- Long, dark body — blackish to dark olive above, only slightly paler below
- Large scales and a moderately pointed head with a terminal mouth, no barbels
- Powerful pharyngeal teeth in the throat, built for crushing snails and molluscs
- Dorsal fin base like a grass carp, but the whole fish is far darker
- Look-alike: grass carp is olive-green and paler with a blunter head; black carp is distinctly blackish
Habits
- A mollusc specialist: feeds on snails, mussels and clams along river bottoms
- Brought to North America for snail control in fish farms; escapes established it in the lower Mississippi basin
- A listed invasive species in the US — wild black carp must not be released; report catches to state agencies
- One of China's four great farmed carps, prized there as a food fish
Distribution
Where to find them
- Deep bends and mussel beds of the lower Mississippi River
- Backwaters and connected lakes of the lower Mississippi basin
- Slow channels around snail-rich riprap and shell beds
Where they live
How to catch them
Bottom fishing over shell beds River
Rig: Running lead, strong size 2/0 hook, 15-25 lb line
Bait/lure: Snail and mussel meat, large dough balls
Key tip: Fish where native mussels concentrate — black carp patrol shell beds at dusk and after dark.
Heavy carp tactics River
Rig: Hair rig with a large boilie or pack-bait ball over a bed of crushed shell
Bait/lure: Large boilies, pack bait, crayfish
Key tip: Gear up: a big black carp in current fights like a grass carp twice its size.
