Federal Status:

State Status:

  • Range: Kansas range map for Arkansas River Speckled Chub
    Dark Blue = Counties with designated critical habitat
    Light Blue = Historical records
  • Comments: The Arkansas River speckled chub (a.k.a., Peppered Chub) is restricted to the upper Arkansas River drainage inhabiting shallow channels over clean sand. This fish is gone from 90 percent of its former range and exists as two disjunct remaining populations; one of these is in Kansas. The habitat for this fish has been lost due to dewatering, pollution and dams that fragment long stretches of streams and inhibit dispersal. A relatively transparent-appearing fish with dark speckles on its back, it grows to 3 inches long. Two fleshy barbels at each corner of its mouth aid in touch and taste. Spawning occurs after a sharp rise in stream flow when water temperatures are above 70 F. The eggs drift downstream with the strong current.
