Asian carp

Consists of 4 species:

  • Silver Carp (Hypophthalmichthys molitrix)
  • Bighead Carp (Hypophthalmichthys nobilis)
  • Black Carp (Mylopharyngodon piceus)
  • Grass Carp (Ctenopharyngodon idella)
Origin:

Southeast Asia. Escaped aquaculture ponds in Southern US in 1970s and migrated up Mississippi/Missouri Rivers.

Identification:
  • 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.
Impacts:

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.

Range Expansion:

Asian carp are spread by migrating in connected waterways and can be introduced by anglers mistakenly using juveniles as bait.
