otoliths or vertebrae of other fish species for at least one to several years (Weber and
Ridgway, 1967; Tsukamoto, 1988).
This study was funded by the Recovery Implementation Program for Endangered
Fish Species in the Upper Colorado River Basin. The recovery program is a joint effort of
the U.S. Fish and Wildlife Service, U.S. Bureau of Reclamation, Western Area Power
Administration, states of Colorado, Utah, and Wyoming, upper basin water users, and
environmental organizations. We thank R. Hamman (Dexter National Fish Hatchery and
Technology Center, Dexter, New Mexico) for providing razorback sucker eggs. K. Bestgen,
L. Crist, T. Modde, T. Nesler, and D. Snyder reviewed earlier drafts. This paper is
contribution no. of the Colorado State University Larval Fish Laboratory.
