Book Description
Since the late 1980's, Snake River sockeye, Oncorhynchus nerka, adults have only returned to Redfish Lake, one of five lakes in the Sawtooth Basin which historically reared sockeye. In 1995 we removed a fish passage barrier at the outlet of Pettit Lake to provide access to more rearing habitat for sockeye. During the same year 8,750 progeny from the captive broodstock program were stocked in Pettit Lake, the only other lake besides Redfish that currently rears Snake River sockeye. In this report, we have summarized activities conducted by Shoshone-Bannock Tribes (SBT) Fisheries Department personnel during the calendar year of 1996. Our objective included fertilization of Redfish Lake, characterizing the limnology of Sawtooth Valley lakes, conducting O. nerka lake population and escapement surveys, reducing the number of spawning kokanee in Fishhook Creek, evaluating hatchery rainbow trout overwinter survival and potential competition and predation interactions with O. nerka in Pettit Lake, and monitoring smolt outmigration from Pettit Lake.

Book Description
Since the late 1980's, Snake River sockeye Oncorhynchus nerka adults have only returned to Redfish Lake, one of five lakes in the Sawtooth Basin which historically reared sockeye. 1997 project objectives included (1) characterization of the limnology of Sawtooth Valley lakes; (2) fertilization of Redfish, Pettit, and Alturas lakes; (3) O.nerka lake population surveys; (4) estimation of kokanee escapement and fry production in Alturas Lake Creek, Stanley Lake Creek, and Fishhook Creek; (5) reduce the number of spawning kokanee in Fishook Creek; (6) evaluate hatchery rainbow trout overwinter survival and potential competition and predation interactions with O.nerka in Pettit Lake; (7) assess predation from bull trout Salvelinus malma, brook trout S.fontinalis, and northern squawfish Ptychocheilus oregonsis on lentic O.nerka; (8) establish screw tap and weir sites to monitor smolt emigration.

Book Description
In March of 1990, the Shoshone-Bannock Tribes petitioned the National Marine Fisheries Service (NMFS) to list the Snake River sockeye salmon (Oncorhynchus nerka) as endangered. As a result of that petition the Snake River sockeye salmon was officially listed as endangered in November 1991 under the Endangered Species Act (56 FR 58619). In 1991 the Snake River Sockeye Salmon Habitat and Limnological Research Program was implemented (Project Number 91-71, Intergovernmental Contract Number DE-BI79-91bp22548). This project is part of an inter-agency effort to save the Redfish Lake stock of O. nerka from extinction. This report summarizes activities conducted by Shoshone-Bannock Tribal Fisheries Department personnel during the calendar year of 1998. Project objectives included; (1) monitor over-winter survival and emigration of juvenile anadromous O. nerka released from the captive rearing program into Pettit and Alturas lakes; (2) fertilize Redfish, Pettit, and Alturas lakes; (3) conduct kokanee (non-anadromous O. nerka) population surveys; (4) monitor spawning kokanee escapement and estimate fry recruitment on Fishhook, Alturas Lake, and Stanley Lake creeks; (5) control the number of spawning kokanee in Fishhook Creek; (6) evaluate potential competition and predation between stocked juvenile O. nerka and a variety of fish species in Redfish, Pettit, and Alturas lakes; (7) monitor limnological parameters of Sawtooth Valley lakes to assess lake productivity. Results by objective are summarized.

The Bonneville Power Administration (BPA) provides funding for this inter-agency recovery program through the Northwest Power Planning Council Fish and Wildlife Program (NPPCFWP). Collaborators in the recovery effort include the National Marine Fisheries Service (NMFS), the Idaho Department of Fish and Game (IDFG), the University of Idaho (UI), U.S. Forest Service (USFS), and the Shoshone-Bannock Tribe (SBT). This report summarizes activities conducted by Shoshone-Bannock Tribal Fisheries Department personnel during the 2000 calendar year. Project objectives include: (1) monitor over-winter survival and emigration of juvenile anadromous O. nerka stocked from the captive rearing program; (2) fertilize Pettit, and Alturas lakes, fertilization of Redfish Lake was suspended for this year; (3) conduct kokanee (nonanadromous O. nerka) population surveys; (4) monitor spawning kokanee escapement and estimate fry recruitment on Fishhook, Alturas Lake, and Stanley Lake creeks; (5) evaluate potential competition and predation interactions between stocked juvenile O. nerka and a variety of fish species in Redfish, Pettit, and Alturas lakes; (6) examine diet of emigrating O. nerka smolts; (7) monitor limnological parameters of Sawtooth Valley lakes to assess lake productivity.

Book Description
In March 1990, the Shoshone-Bannock Tribes petitioned the National Marine Fisheries Service (NMFS) to list Snake River sockeye salmon (Oncorhynchus nerka) as endangered. Snake River sockeye salmon were officially listed as endangered in November 1991 under the Endangered Species Act (56 FR 58619). In 1991, the Snake River Sockeye Salmon Habitat and Limnological Research Project was implemented. This project is part of an interagency effort to prevent the extinction of the Redfish Lake stock of Snake River sockeye salmon. The Shoshone-Bannock Tribal goal for this project is two tiered: The immediate goal is to increase the population of Snake River sockeye salmon while preserving the unique genetic characteristics of the Evolutionarily Significant Unit (ESU). The Tribes long term goal is to maintain a viable population that warrants delisting and provides Tribal harvest opportunities. The Bonneville Power Administration (BPA) provides funding for this interagency recovery. Collaborators in the recovery effort include the National Oceanic and Atmospheric Administration (NOAA), the Idaho Department of Fish and Game (IDFG), the University of Idaho (UI), and the Shoshone-Bannock Tribes (SBT). This report summarizes activities conducted by Shoshone-Bannock Tribal Fisheries Department personnel during the 2005 calendar year. Project tasks include: (1) monitor limnological parameters of the Sawtooth Valley lakes to assess lake productivity; (2) conduct lake fertilization in Pettit and Alturas lakes; (3) reduce the number of mature kokanee spawning in Fishhook and Alturas Lake creeks; (4) monitor and enumerate sockeye salmon smolt migration from Pettit and Alturas lakes; (5) monitor spawning kokanee escapement and estimate fry recruitment in Fishhook, Alturas Lake, and Stanley Lake creeks; (6) conduct sockeye and kokanee salmon population surveys; (7) evaluate potential competition and predation between stocked juvenile sockeye salmon and a variety of fish species in Redfish, Pettit, and Alturas lakes; and (8) assist IDFG with captive broodstock production activities.
