Ages assigned to 503 round whitefish (Prosopium cylindraceum (Pallas)) from the Leaf River on the basis of otoliths differed notably from those assigned on the basis of scales only for fish above age 8. The hyaline zones in otoliths corresponded to the scale annuli, and the growth increments in otoliths at various dates as percentages of the totals during the collection period were similar to those for scales. Otolith radius increased linearly with fork length, as did otolith weight with fish age.
