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.
