Hoopa Valley Tribe’s Draft Plan For Trinity River Coho Harvest 2/21/2015


Draft Plan “Hoopa Valley Tribe’s Fishery Harvest and Conservation Plan For Trinity River Coho Salmon Summer 2015”

I. INTRODUCTION This harvest plan is under authority of the Hoopa Valley Tribal Council (HVTC) who exerts both regulatory and enforcement jurisdiction on the Hoopa Valley Reservation. This plan sets forth specific concepts and constraints for managing a selective fishery for hatchery-origin (“hatchery”) Coho salmon (Oncorhynchus kisutch) on the Hoopa Valley Reservation which contains the lower 26 km of the Trinity River. The plan anticipates full mitigation at Trinity River Hatchery (TRH) and near full exploitation of hatchery Coho salmon. Conservation of non-hatchery-origin (“natural”) Coho is affected through (1) selective removal of hatchery adults while passing natural Coho salmon upstream, and (2) a sorting weir in vicinity of Lewiston for regulating presence of hatchery spawners and collecting natural broodstock for use at TRH. Complementary hatchery practices such as envisioned in the California Hatchery Scientific Review Group (CAHSRG) recommendations for the Coho program at TRH are also discussed. The HVT will conduct a selective fishery using a weir and targeting Trinity River Hatchery (TRH) Coho salmon commencing in mid-October through November of 2015. The selective fishery will occur within the exterior boundaries of the Hoopa Valley Reservation with an overall harvest impact of no more than 10,000 adult hatchery Coho salmon identified by the absence of the right maxillary bone1 . The fish harvest weir shall be deployed in the main-stem Trinity River at or near the southern boundary of the Hoopa Valley Reservation (HVR). The HVT will determine how harvested fish will be allocated among ceremonial, commercial, and subsistence uses. Trinity River Coho salmon are a part of the Southern Oregon and Northern California Coastal (SONCC) Evolutionarily Significant Unit (ESU) which were federally listed as “Threatened” under the Endangered Species Act (ESA) in 1997. The selective weir fishery shall be managed to pass natural Coho salmon above the facility unharmed. The HVT Fisheries Department shall provide extensive monitoring of the fishery to estimate total encounters with and harvest of Coho salmon. The fishery will be managed by guidelines of this plan and regulated by preseason amendment and inseason adjustments to Tribal fishing regulations as promulgated by HVTC.
