Silver Carp
Silver Carp are invasive Asian carp that have established populations throughout Iowa's major river systems since their first detection in 1986.
Scientific Name: Hypophthalmichthys molitrix
- These deep-bodied, laterally compressed fish are easily recognizable by their silvery coloration, scaleless heads, upturned mouths, and distinctive jumping behavior when startled by boat motors.
- They commonly reach 20 pounds with some individuals exceeding 80 pounds, making them formidable opponents on fishing tackle.
