Download or read book Upstream Passage, Spawning, and Stock Identification of Fall Chinook in the Snake River, 1992 and 1993 written by and published by . This book was released on 1997 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: This final report of the 3-year study summarizes activities and results for 1993. Study objectives were to: (1) determine the source of losses (or accounting errors) for adult chinook salmon between Ice Harbor Dam (IHR) and Lower Granite Dam (LGR), and upstream of LGR in the Snake River; (2) identify spawning locations upstream of LGR for calibration of aerial redd surveys, redd habitat mapping, carcass recovery for genetic stock profile analysis, and correction of estimated adult/redd ratios; and (3) estimate passage and migration times at Snake River. 200 fall chinook salmon were radio tagged and tracked with aerial, fixed-site, and ground mobile tracking. Fish were released upstream of IHR at Charbonneau Park (CHAR). 190 of the fish were tracked or relocated away from CHAR. 59 fish descended to below IHR without crossing Lower Monumental Dam (LMO). Another 128 salmon passed upstream of LMO without falling back at IHR. Only 80 salmon passed Little Goose Dam (LGO) without falling back at a downstream dam; 66 of these fish passed LGR. Many fish that fell back reascended the dams. A total of 72 salmon released at CHAR passed upstream of LGR, including fish that had fallen back and reascended a dam. Over 80 percent of the salmon that entered Lyons Ferry Hatchery each year had reached LGO before descending to the hatchery. Extensive wandering was documented between LMO and upstream of LGR before salmon entered Lyons Ferry Hatchery or the Tucannon River. In 1993, 41 salmon were found to be of hatchery origin when recovered. These fish entered Lyons Ferry Hatchery with similar movements to unmarked salmon. Each year a few salmon have remained near the hatchery without entering, which suggests the hatchery may have inadequate attraction flows. Fall chinook passed lower Snake River dams in 2-5 days each on average. Median travel times through LMO and LGO were 1.0-1.3 days each, which was slower than for spring chinook or steelhead in 1993. 5 refs., 21 figs., 20 tabs.

Download or read book Survival of Hatchery Subyearling Fall Chinook Salmon in the Free-Flowing Snake River and Lower Snake River Reservoirs, 1998-2001 Summary Report written by and published by . This book was released on 2002 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report results from four years (1998-2001) of an ongoing study of survival and travel time of subyearling fall chinook salmon in the Snake River. We report analyses of associations among river conditions and survival and travel time estimates, which include data from 1995 through 1997. At weekly intervals from early June to early July each year (mid-May to late June in 2001), hatchery-reared subyearling fall chinook salmon were PIT tagged at Lyons Ferry Hatchery, trucked upstream, acclimated, and released above Lower Granite Dam at Pittsburgh Landing and Billy Creek on the Snake River and at Big Canyon Creek on the Clearwater River. Each year, a small proportion of fish released were not detected until the following spring. However, the number that overwintered in the river and migrated seaward as yearlings the following spring was small and had minimal effect on survival estimates. Concurrent with our studies, a number of subyearling fall chinook salmon that reared naturally in the Snake River were caught by beach seine, PIT tagged, and released. We compared a number of characteristics of hatchery and wild fish. Hatchery and wild fish were similar in 2001, and from 1995 through 1997. Results for 1998 through 2000 showed some relatively large differences between hatchery and wild fish. However, recent information suggests that a considerable proportion of wild subyearling chinook salmon migrating in a given year may actually be stream-type (spring/summer), rather than ocean-type (fall) fish, which may account for some of the differences we have observed.

Download or read book Snake River Fall Chinook Salmon Brood-Stock Program, 1981-1986 Final Report of Research written by and published by . This book was released on 1987 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the Snake River Fall Chinook Salmon Brood-stock Program was to hatch eggs from upriver stocks, rear the fish to spawning maturity, and use the resulting eggs for stock restoration in the Snake River. Approximately 15,000 eyed Snake River fall chinook salmon eggs were obtained each winter in 1981, 1982, 1983, and 1984 from various Columbia River hatcheries. Fish from these eggs were reared in dechlorinated City of Seattle water at the Northwest and Alaska Fisheries Center or in constant 10.5°C groundwater at the University of Washington's Big Beef Creek Research Station. Seawater tolerance trials of 0+ age (3--5 months) juveniles in all four brood stocks were strongly suggestive of the 1+ age smoltification pattern of spring chinook salmon. Attempts to transfer 0+ age fish to marine net-pens at the Manchester Marine Experimental Station were unsuccessful during the four brood years. The only Snake River fall chinook salmon that demonstrated acceptable survival after 4 months residence in seawater were fish that were transferred as 1+ age smolts. After smolts were successfully transferred to seawater, losses were minimal for several months. However, in all Snake River chinook salmon stocks, mortality due to bacterial kidney disease (BKD) and a previously undescribed ''rosette disease'' resulted in very few maturing fish at 4 or 5 years of age. 5 refs., 7 figs.

Download or read book Snake River Fall Chinook Salmon Brood-Stock Program, 1984 Annual Report of Research written by and published by . This book was released on 1985 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective is the enhancement of upriver stocks through research and development of an eggbank source. Viable gametes, produced from fish held to maturity in sea pens, will be made available for restoration purposes on the Snake River. Seawater entry trials with 0+-age and 1+-age fish have shown that 0+-age Snake River fall chinook salmon are not amenable to seawater entry and will either die or require up to 6 months to fully adapt to seawater. However, 1+-age smolts experience little problem at seawater entry; it is therefore suggested that Snake River fall chinook salmon be released as 1+ smolting fish in hatchery situations. Important marine mortalities occurring from osmoregulatory dysfunction, Bacterial Kidney Disease, and precocity at various life stages have been documented. Also, a previously unreported marine fungal pathogen has been identified. Mortality from this pathogen occurs from 3-years of age to maturity and can exceed 0.5% per day (resulting in losses to 90+%). At the end of December 1984, Snake River fall chinook salmon from 1980 (n = 67), 1981 (n = 876), 1982 (n = 4809), and 1983 (n = 7100) broods were under production. Because of the extensive mortality due to the marine fungal pathogen, only seven spawners were obtained from the 1980 stock in fall 1984. The 1980-brood spawners produced only minimal eggs and these will be used to investigate possible vertical transmission of the fungal pathogen. 4 figs.

This book was released on 1998 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1996, the National Marine Fisheries Service, the Nez Perce Tribe, and the U.S. Fish and Wildlife Service completed the second year of cooperative research to investigate migrational characteristics of subyearling fall chinook salmon in the Snake River Basin. In spring and early summer, we captured natural subyearling fall chinook salmon by beach seine, PIT tagged them, and released them in two reaches of the Snake River. Also, subyearling fall chinook salmon reared at Lyons Ferry Hatchery were PIT tagged at the hatchery, transported, and released weekly at Pittsburg Landing on the Snake River and Big Canyon Creek on the Clearwater River to collect data on survival detection probabilities, and travel time.
