Project
Title: Nez Perce Tribe 2017 Separation by Code Request
Project Lead: Jason Vogel
Agency: NPT
Project Number: 14110-4-J010, 199701501, 1983350003
Funding Agency: BPA
Project Objectives: The Lower Snake River Compensation Plan (LSRCP) project cooperative agreement 14110-4-J010, the Imnaha Smolt Monitoring Project (SMP) #199701501, the Nez Perce Tribal Hatchery Monitoring and Evaluation Project (NPTH M&E) #1983350003, and the Coho Project administered by the Nez Perce Tribe are requesting to use the Separation by Code system (SbyC) in Lower Granite, Little Goose, Lower Monumental, and McNary Dams. This request will utilize several action codes for our hatchery and natural Chinook salmon, steelhead trout, and Coho emigrating in the year 2017 and into the future. The LSRCP and SMP Monitoring Project are in place to perform emigration studies on the Imnaha River, and NPTH M&E on the Clearwater River to determine and compare hatchery reared and natural fish smolt performance variables such as travel time, arrival timing, and estimated survival to Lower Granite Dam and McNary Dam. Arrival timing information allows salmon managers to make meaningful flow and spill management requests to maximize survival potential through the hydroelectric corridor. We also propose to estimate relative smolt to adult return rate (SAR) of spring and fall emigrating natural Chinook salmon and steelhead smolts back to Lower Granite Dam. The Coho project has been a reintroduction initiative to try and reestablish Coho into the Clearwater Basin. This effort has been a cooperative effort from many agencies, including the United States Fish and Wildlife Service, State of Idaho and others. We propose to measure fish smolt performance variables such as travel time, arrival timing, and estimated survival to Lower Granite Dam and McNary Dam and estimate relative smolt to adult return rate (SAR) of hatchery coho salmon back to Lower Granite Dam. The LSRCP, SMP, and NPTH M&E studies are covered under the NOAA Fisheries Northwest Region Protected Resources Division Endangered Species Act (ESA) Section 10 Permit #1134. Current Default Operations for Juvenile Fish Juvenile fish emigrate through each hydro-facility in one of three ways; fish emigrate through a facility undetected (through spill or turbines); emigrate through the bypass system and get placed in the transport system; or emigrate through the bypass system and gets placed back in-river. Using the current default settings, PIT tagged fish, are always bypassed back into the river while untagged fish are transported. This results in the PIT tagged fish no longer representing the general population of fish. This eliminates our ability to calculate accurate SAR and returning adult abundance of the general non-tagged juvenile population. To generate accurate SAR’s and adult abundance information we need a means of representing non-PIT tagged fish that emigrate through the system undetected, are detected and placed on a barge, or detected and bypassed (lower dams). Objectives for LSRCP, SMP, NPTH M&E, and Coho projects: 1: Continue to obtain life stage specific survival estimates to Lower Granite Dam utilizing detections to calculate survival with the SURPH model. 2: Obtain SAR and returning adult abundance information on the general population of migrating fish (largely transported) using a representative group of PIT tagged fish. These projects are going to PIT tag two separate representative groups at the natal stream, one group for each of the above objectives. Objective 1: Will be implemented by utilizing the current default SbyC settings (bypass PIT tags back to the river) at each hydro-facility. Detections from this group will be modeled through the SURPH program to obtain life-stage specific survival estimates from natal stream to Lower Granite Dam. No special SbyC action is required for this objective. Objective 2: Will require use of the SbyC system to represent the general population of fish to obtain accurate SAR's and adult abundance information. These projects will utilize a predefined group of PIT tags from the Imnaha River and in conjunction with the SbyC system, to accurately represent each river systems general population of juvenile spring/summer Chinook salmon and steelhead trout in their different migration routes through the hydro-system. These PIT tagged fish from the two groups will be designated in the SbyC system into a “monitor mode” (no action). These specific PIT tags will be transported, bypassed, or remain undetected in the same relative proportion as non-PIT tagged fish. Therefore, returning PIT tagged adults would accurately represent non-tagged adults regardless of juvenile detection rates, transportation rates, in river-survival rates, and potential delayed mortality of in-river and transported fish. These adult PIT tag detections can then be used to calculate accurate SAR’s and adult abundance estimates. Below is a list of the specific SbyC facilities and required actions at each facility. Location of Actions: Lower Granite, Little Goose, Lower Monumental, and McNary Dams Duration and State Date: Entire Season SbyC is operational in 2017 General Action Request: Place all tag codes (100%) into “Monitor Mode”, No Action is taken Action 1: Imnaha River natural juvenile Chinook salmon group Approximate number of PIT tags released at stream = 10,000 Action 2: Imnaha River natural juvenile steelhead group Approximate number of PIT tags released at stream = 4,000 Action 3: Nez Perce Tribal Hatchery juvenile chinook group Approximate number of PIT tags released at stream = 4,000 Action 4: Coho Clearwater hatchery juvenile group Approximate number of PIT tags released at stream= 15,000 The request of these actions and the resulting information will be critical in the analysis of these populations using representative SAR’s and adult return information for both projects. The PIT tagged fish that are transported will also complement the Comparative Salmon Survival Study (CSS) that is currently in need of transported natural PIT tagged fish. The request of these actions and the resulting information will be critical in the analysis of these populations using representative SAR’s and adult return information for both projects. The PIT tagged fish that are transported will also complement the Comparative Salmon Survival Study (CSS) that is currently in need of transported natural PIT tagged fish. Additional information was requested by FPAC regarding the number of PIT tags that the Nez Perce Tribe would likely be placing in the "Default" mode. The Tribe will likely be tagging around 45-50,000 additional fish that will be placed into the default mode. This tagging will be for both natural and hatchery tagging in the Clearwater, Salmon, Grande Ronde, and Imnaha basins.
Study Description: Over past fifteen years the Nez Perce Tribe has utilized Separation by Code (SbyC) to implement crucial studies on several of our programs. During each of these past thirteen years NPT has received approval for these research activities. This is the 2017 Nez Perce Tribe request for approval. Additional information was requested by FPAC regarding the number of PIT tags that the Nez Perce Tribe would likely be placing in the "Default" mode. The Tribe will likely be tagging around 45-50,000 additional fish that will be placed into the default mode. This tagging will be for both natural and hatchery tagging in the Clearwater, Salmon, Grande Ronde, and Imnaha basins.

Smolt-to-Adult Ratio: Calculating estimates of SAR is not the primary objective of these studies. Sample sizes of our mark groups only allow for opportunistic looks at SAR when they can be calculated.
