2 Acknowledgments Program Staff Lower Snake River Compensation Plan – OfficeIdaho Department of Fish and GameForest Service – Salmon-Challis Nat’l ForestAnd a guy on a buffalo!!!With that, I would like to acknowledge the support we received from the Shoshone-Bannock Tribes Fort Hall Business Council and key program staff including Carlos Lopez, Alex Graves, Scott Brandt, Brock Moss & the numerous staff that assisted with the program over the years.We are especially thankful to Scott, Steve, Chris, Joe, Margaret, & Tammy at the Lower Snake River Compensation Plan – Office for their support of the program, both financially and fundamentally.We would like to thank Idaho Department of Fish & Game including Pete, Sam &Tom at headquarters; Brent, Mel, & Danielle at Sawtooth Fish Hatchery.We would like to thank NOAA-Fisheries and the US Forest Service for supporting this Tribal supplementation program.And lastly, we are hopeful that BPA will become a program sponsor. Funding from BPA for the project was negotiated in our Fish Accord and the Tribes’ Supplementation Program is currently being reviewed by the ISRP through the Council’s Categorical Review.
4 Program Overview Background Vision, Goals, and Objectives Features AccomplishmentsFuture Work
5 Background How the Steelhead Streamside Incubator Program got started Pre – 1970Ample harvest opportunities for Chinook salmon and steelhead1972State vs. Tinno; Shoshone-Bannock Tribes Fort Bridger Treaty Rights are challenged over a fishing incident in the Yankee Fork Salmon River1970’s – 90’sHarvest opportunities become more and more limitedAn occasional “bathtub fishery” stimulates harvest1975Tribal Game Code establishedRegulates harvest of salmon and steelheadFisheries begin to be constrained1977 – 1991Policy supported native fish population managementCertain areas were designated for harvest (e.g., Yankee Fork) and other areas curtailed (e.g., Bear Valley Creek)Designated harvest areas did not have fish and interest in fishing waned1991 – 1994South Fork Salmon River provides fishery benefits on hatchery Chinook salmonHatchery fish save cultural, traditional ,and subsistence-based linkages to anadromous fishHatchery fish rejuvenate interest in fishingPolicy decision makers shift to supporting artificial production as a tool to provide harvestLeast intrusive artificial propagation techniques pursuedTribes propose Chinook eggbox programsLack of support and broodstockTribes propose using eggboxes with steelhead1995 – Steelhead Streamside Incubation Program initiated
6 Vision“The Tribes will pursue, promote, and where necessary, initiate efforts to restore the Snake River systems and affected unoccupied lands to a natural condition. This includes the restoration of component resources to conditions which most closely represents the ecological features associated with a natural riverine ecosystem. In addition, the Tribes will work to ensure the protection, preservation, and where appropriate‐the enhancement of Rights reserved by the Tribes under the Fort Bridger Treaty of 1868 and any inherent aboriginal rights.”
7 Goals Increase harvest opportunities for Tribal members Provide connection with and protection of cultural and social values and rightsDevelop an experimental project for assessing the potential for using artificial production to increase early life survival of steelhead and salmon populations
8 Management Objectives Harvest objectivesincrease from baseline conditionspreserve traditional fishing techniquesProduction objectivesincrease egg to fry survivaltest streamside incubation technologydetermine optimum egg loading density and configurationsincubate 1,000,000 eyed eggs annuallyYankee Fork – 500,000Panther Creek – 400,000Indian Creek – 100,000Additional objectivesminimize cost, process, and fish handlingincrease community education, involvement, and participationfulfill the requirements of US vs. Oregon
9 Program Features remote incubation site set-up acquisition of eyed-egg from local hatcheriestransportation of eyed-eggs to remote incubatorsdaily incubator operations and maintenancedead egg count and volitionally fry releaseremote incubation site disassemble
10 Program Accomplishments Successfully identified preferred incubation methods (i.e. upwellers)Involved the communityDance of the SalmonPrivate LandownersCompleted initial M&E using DNA parentage analysisRecently secured funding to fully implement the program and conduct M&E
12 Monitoring, Research, & Evaluation Conducted parental exclusion/pedigree analysisBroodstock collected and spawned at Sawtooth FH from 2006 – 2008Eggs outplanted into remote incubators in Yankee ForkJuvenile steelhead were sampled in tributary habitats of Yankee Fork from 2006 – 2009randomly select sampling sites throughout watershedconducted electrofishing: 3-pass removal w/ block netscollected tissue samples from age-0+ and age-1+ juvenile steelheadCompared parental genotypes of broodstock fish to unknown origin Yankee Fork juvenilesdetermine relative abundance of SSI progeny and natural origin progeny
13 M & E Approach: F1 generation 2. Collect and Incubate Eggs3. Incubate Eyed-eggs inincubators1. Spawn Hatchery Adults4. Release fryvolitionally5. Collect 0+ parrduring first fall6. Collect 1+ parr duringsecond fall
