Arkansas River Speckled Chub Macrhybopsis tetranema
Federal Status:
None
State Status:
Endangered
Range:
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.
