Available in PDF, EPUB and Kindle. Book excerpt: In 1986, a multi-year project to evaluate the biological feasibility of reestablishing anadromous sockeye salmon (Oncorhynchus nerka) runs to Cle Elum Lake in the Yakima River Basin was established between the Bonneville Power Administration (BPA) and the National Marine Fisheries Service (NMFS). This program involves the capture, spawning, and rearing of disease-free donor stock in 1987 and 1988 and assessment of juvenile outmigration and survival from Cle Elum Lake in 1989 and 1990. Work in 1987--1988 involved collection of adult sockeye salmon from the Lake Wenatchee run and incubation and rearing of progeny as donor stock. In July 1987, 263 adults were captured at the Dryden fishway on the Wenatchee River and transferred to net-pens in Lake Wenatchee. Adults were held approximately 90 days and spawned, and the eggs were transferred to a quarantine hatchery. Pre-spawning survival was 95.1%, and all spawners were certified as being free of Infectious Hematopoietic Necrosis (IHN) and other replicating viruses. Egg viability averaged about 40%; however, eyed egg to hatch survival was over 99%. Juveniles are being reared in quarantine, and survival to date is about 92%. The NMFS currently has over 131,000 fry (0.7 g average weight) in culture. Fry have been certified twice (at 0.12 g and 0.25 g average weight) as being free of IHN and other replicating viruses. Viral certification will continue throughout rearing. 13 refs., 4 figs., 3 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes research activities conducted by the National Marine Fisheries Service (NMFS) from July 1988 through March 1989 relating to the Cle Elum Lake sockeye salmon restoration feasibility study. During this period, efforts focused on collection and spawning of adult sockeye salmon from the Wenatchee River, incubation of eggs from the 1988-brood, and the rearing of juveniles from the 1987-brood. In late July and early August 1988, 520 adult sockeye salmon were captured at fishways on the Wenatchee River and transferred to net-pens in Lake Wenatchee. Fish were held to maturity in late September and early October, spawned, and eggs incubated at a quarantine hatchery in Seattle, WA. The 336 sockeye salmon successfully spawned from the net-pens at Lake Wenatchee were surveyed for the presence of infectious hematopoietic necrosis (IHN) and other replicating viruses. In addition, 13 and 5 sockeye salmon spawners were surveyed from spawning grounds on the White and Little Wenatchee Rivers, respectively, from within the Lake Wenatchee system. 12 refs., 4 figs., 6 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: The focus of this research was to study the feasibility for anadromous salmonids to recolonize the habitat above reservoirs in the Yakima River without disruption to irrigation withdrawals. A primary concern was whether anadromous fish could successfully exit reservoirs and survive downstream passage through the Yakima and Columbia Rivers to the ocean.
