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.
