Notes | The Oregon chub is presently found only in the Umpqua and Willamette drainages. This rare fish seems to be in decline. This study attempts to describe life history, habitat requirements, reproduction, and diet of the Oregon chub. One factor in its decline seems to be its need for slowly moving or slack water as a habitat. The related Umpqua chub can survive in faster-moving waters and is doing better. Methods of identifying larvae are given. The major professors for this Masters thesis were Hiram W. Li and Douglas F. Markle. |
