Spring Outmigration of Wild and Hatchery Chinook Salmon and Steelhead Trout Smolts from the Imnaha River, Oregon; 1996 Annual Report.
- Nez Perce Tribe, Lapwai, ID
For the third consecutive year, the Nez Perce Tribe, in conjunction with the Fish Passage Center, participated in the smolt monitoring program in the Imnaha River. A rotary screw trap was used to collect emigrating wild and hatchery chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (Oncorhynchus mykiss) smolts from February 23 to June 24, 1996. A total of 1,797 wild chinook salmon, 11,896 hatchery chinook salmon, 3,786 wild steelhead trout, and 31,094 hatchery steelhead trout smolts were captured during outmigration studies on the Imnaha River in 1996. Mortality associated with trapping, handling and tagging was low, being 1.4% for wild chinook, 0.18% for hatchery chinook, 0.21% for wild steelhead and 0.28% for hatchery steelhead trout smolts.
