Silver Carp
Silver Carp are invasive planktivorous fish that pose a significant threat to South Dakota's aquatic ecosystems.
These filter-feeding fish are notorious for their ability to leap up to 10 feet from the water when startled by boat motors, creating safety hazards for boaters.
Scientific Name: Hypophthalmichthys molitrix
- These filter-feeding fish have narrow, deep bodies covered in very small silver scales, with large toothless mouths and upturned lower jaws.
- They can grow upwards of 3 feet long and commonly reach 20 pounds, with some individuals exceeding 80 pounds.
