Consists of 4 species:
- Silver Carp (Hypophthalmichthys molitrix)
- Bighead Carp (Hypophthalmichthys nobilis)
- Black Carp (Mylopharyngodon piceus)
- Grass Carp (Ctenopharyngodon idella)
Southeast Asia. Escaped aquaculture ponds in Southern US in 1970s and migrated up Mississippi/Missouri Rivers.
- Silver Carp: Scale-less head, low set eyes, upturned mouth, and keel extends to isthmus, generally silver coloration.
- Bighead Carp: Scale-less head, low set eyes, upturned mouth, and keel extends only to pectoral fins, generally blotchy coloration.
- Black & Grass Carp: Have large scales (similar to common carp), with an olive to blackish brown body.
These fish are highly adaptive, prolific spawners that quickly outgrow potential controls by predation and compete with juvenile game fish and native invertebrates for food resources. Silver carp pose a physical danger because of their leaping ability. These large fish may collide with boaters, personal watercraft, or water skiers and cause serious injury.
Asian carp are spread by migrating in connected waterways and can be introduced by anglers mistakenly using juveniles as bait.
