Yellowfin Madtom

Yellowfin Madtom – approximately 8,300

Noturus flavipinnis

Conservation Fisheries, Knoxville, Tennessee

A small catfish confined to the Tennessee River Valley, the yellowfin madtom for eons laid its eggs under rocks. Along came farmers and cows, their activity filling the rivers with silt. Gone were the nooks and crannies the madtom needed to reproduce. Survivors carry their genes into a murky future.
