ResourceProblems Migration barriers to anadromous fish
Locally-adapted broodstock program (Phase I) 1) Collection in Omak Creek & Okanogan River 2) Collection of 16 adult steelhead (8 male, 8 females) 3) Differentially marked – based on parental origin 4) Monitoring returning adults and spawning success
Collection of broodstock, in Omak Creek and Okanogan River Picket weir Trap net Angling
8 steelhead collected [4 males (1W, 3H); 4 females (2W*, 2H)]
Spawning – April 11 1 wild male X 3 females (1H, 2W*) Cross (m x f) Egg take Egg loss Ponding loss W x W 6,600 100% n/a W x W 3,409 2.6% 12 W x H 6,000 1.4% 8
Broodstock virology testing: (tissues, ovarian fluids) EHN, IHN, IPN, OMV, SVC, VHS
Allproduction will be marked (differentially) with Elastomer tags
Monitoring & Evaluation:12 years Assessments: Returning adults Redd surveys Juvenile abundance Smolt origin
Recommendations 1) Improve ability to collect broodstock 2) Ability to collect smolts 3) Initiate a kelt reconditioning program
