Project
Title: Comparative Survival Study 2017
Project Lead: Michele DeHart
Agency: FPC
Project Number: 1996-020-00
Funding Agency: BPA
Project Objectives: Since migration year 1997, the Comparative Survival Study (CSS) has provided analyses for the evaluation of current and past year's management operations with regard to spill, bypass, and transportation routes of hydrosystem passage versus a management operation without transportation. The CSS is requesting SbyC operations only for those PIT-tagged fish for which Fish Passage Center staff will be making the SbyC pre-assignments. These PIT tags will be submitted to PSMFC for placement on the SbyC databases at the transportation dams with the Action Code of 100% Monitor Mode (i.e., routed the same as their untagged counterparts). These transportation dams are Lower Granite, Little Goose, and Lower Monumental. No request is required for the Return-to-River Group, since this is the current default action at these dams. There will be no "take" or "handling" of PIT-tagged fish as a result of the requested sort-by-code of 100% Monitor Mode.
Study Description: Since 2006, PIT-tagged fish in the CSS have been pre-assigned to either the "Monitor Mode" group or "Return-to-River" group. Fish assigned to "Monitor Mode" reflect the experience of the untagged population while fish assigned to the "Return-to-River" group allow for estimations involving a bypassed treatment after transportation has begun.
Juvenile
Juvenile Description: The CSS is participating with Lower Snake River Compensation Program (LSRCP), Idaho Power Company (IPC), Dworshak National Fish Hatchery, and the Smolt Monitoring Program (SMP) to PIT-tag a representative portion of the hatchery spring/summer Chinook, hatchery summer steelhead, hatchery sockeye, and hatchery subyearling fall Chinook production originating above Lower Granite Dam and to assign these fish as Monitor Mode or Return-to-river Mode. Several entities cooperate with the CSS and participate in this endeavor. The CSS contributes a portion of the PIT-tags being used at each hatchery releasing spring/summer Chinook, fall Chinook, steelhead, and sockeye at locations above Lower Granite Dam. Spring/Summer Chinook releases include those tagged at Dworshak (~42,000) , Clearwater (~72,700), Rapid River (~52,000), McCall (~52,000), Pahsimeroi (~22,400), Sawtooth (~22,400), and Lookingglass (~42,000) hatcheries. Fall Chinook releases include subyearlings reared at Lyons Ferry Hatchery and acclimated at three release sites on the Snake and Clearwater rivers (above LGR): Captain Johns Rapids (26,000), Pittsburg Landing (26,000), and Big Canyon Creek (11,100). Summer steelhead releases include those tagged at Dworshak (~34,400), Clearwater (~18,100), Magic Valley (~34,800), Hagerman (~17,200), Niagara Springs (~22,700), Irrigon (~37,000) (releases in Grande Ronde and Imnaha rivers), and Lyons Ferry (~6,000) (release in Grande Ronde River) hatcheries. Sockeye releases include those tagged at Spingfield (~52,000) hatchery. The CSS will be assigning the SbyC “Monitor-Mode” action for PIT-tagged spring/summer Chinook at Dworshak, Rapid River, McCall, and Lookingglass (Imnaha and Catherine Creek stocks) hatcheries, PIT-tagged fall Chinook at Captain Johns, Pittsburg Landing, and Big Canyon Creek acclimation ponds, PIT-tagged steelhead at Dworshak, Clearwater, Magic Valley, Hagerman, and Niagara Springs, and PIT-tagged sockeye at Springfield hatchery. SbyC “Monitor-Mode” pre-assignments for the other hatchery fish are conducted directly by their associated state agencies. The CSS will also be making the SbyC “Monitor-Mode” pre-assignments for wild Chinook and wild steelhead PIT tagged by the state fishery agencies of Idaho and Oregon and tribes of the Umatilla, Nez Perce, and Shoshone-Bannock.
Smolt-to-Adult Ratio: All of the PIT-tagged fish from the CSS are used to estimate SARs. For Snake River spring/summer Chinook, fall Chinook, steelhead, and sockeye, the CSS provides estimates of overall SARs, as well as route-specific SARs (i.e., transported vs. in-river migrants).
Collection Efficiency: Under the CSS, only about 70% of the total PIT-tagged fish are assigned to "Monitor Mode". Therefore, the other 30% of the releases can be used to generate estimates of collection efficiency.
