This book was released on 2010 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The primary objective of this review is to compile and synthesize reported information on adult Pacific salmonids (Oncorhynchus spp.) relevant to their life history, migration, behavior, and survival in the Willamette River basin ... The presented material is intended to supplement the USACE's implementation strategy for the Willamette Project Biological Opinion (BiOp, NMFS 2008), which includes water management, fish passage, dam operation, water quality, hatchery program, and habitat components. While we conducted this review while considering the management actions presented in the BiOp's reasonable and prudent alternative (RPA), we generally used a biologically-based approach to identifying information gaps." -- Introduction, page 1.

Hargrove and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes life history and genetic diversity information for wild adult steelhead (Oncorhynchus mykiss) and spring/summer Chinook Salmon (O. tshawytscha)sampled at Lower Granite Dam and later detected in a Distinct Population Segment (DPS) or Evolutionarily Significant Unit (ESU) in the Snake River basin for the 01/01/2022 to 12/31/2022reporting period. This reporting period covers analysis of individuals crossing Lower Granite Dam in spawn year (SY) 2022. A total of 1,917 steelhead and 2,791 Chinook Salmon were sampled at Lower Granite Dam. Of the fish tagged at Lower Granite Dam, 930 steelhead and 1,732 Chinook Salmon were subsequently identified at a PIT tag array within the boundary of a population in the Snake River basin. Panels of up to 368 SNPs were genotyped at both Idaho Department of Fish and Game’s Eagle Fish Genetics Lab and the Columbia River Inter-Tribal Fish Commission’s Hagerman Genetics Lab, to assign these fish to hatchery parents or wild genetic stocks. We describe the life history variation and genetic diversity of steelhead and Chinook Salmon detected in Snake River populations for SY2022. The information presented in this report provides critical data for viable Salmonid population monitoring of the Snake River steelhead DPS and the Snake River spring/summer Chinook Salmon ESU.

Download or read book Life History and Evolutionary Adaptation of Pacific Salmon and Its Application in Management written by Mary Jo Wevers and published by . This book was released on 1993 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: An approach to understanding and managing anadromous salmon, steelhead, and sea-run cutthroat trout (Oncorhynchus spp.) based on life history and evolutionary adaptive capacities of species and stocks is presented. Species, stocks, and local populations are viewed as systems that are continuously adapting to changing environmental conditions. They have the potential capacity to evolve in different ways in different environments through both life history and evolutionary adaptation. Habitat organization forms a template for genus, species, stock, and local population life history organization. Harvesting, habitat alteration resulting from land use practices and other human activities can alter the organization and adaptive capacities of species and stocks, and thus their long term persistence. The adaptive capacity of Oncorhynchus relative to its habitat and management environment is examined at the species, stock, and local population levels. Life history characteristics of representative stocks and local populations are analyzed using Detrended Correspondence Analysis (DECORANA). Fresh water migration distance and latitude are used to "explain" ordination patterns of Oncorhynchus species in the North Pacific Basin. Fresh water migration difficulty and mean annual runoff are used to interpret life history patterns of Columbia Basin chinook salmon stocks. Upstream migration difficulty and fall water temperatures are used to explain the ordination patterns of local populations of Willamette spring chinook salmon. Fishery management practices are examined in terms of their impacts on the organization and adaptive capacity of species, stocks, and local populations of Oncorhynchus. Management generalizations and guidelines derived from the life history theory are applied to management of Willamette spring chinook salmon. Maintaining habitat changes in the Willamette Basin within the historic range of fluctuations will tend to maximize co-organization of local populations. Management activities should provide relatively constant habitat and fishery conditions for natural selection processes to "organize" life history traits over a period of at least a few generations. Fisheries should selectively harvest local populations that show a high degree of realization of their adaptive capacity. By focusing instead on maximizing the co-organization of stocks, their habitat and fishery environments, and protecting the adaptive capacities of stocks, we will go a long way toward providing long-term sustainability for social communities dependent on fisheries.

Download or read book Migratory Behavior of Adult Spring Chinook Salmon in the Willamette River and Its Tributaries written by and published by . This book was released on 1994 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Migration patterns of adult spring chinook salmon above Willamette Falls differed depending on when the fish passed the Falls, with considerable among-fish variability. Early-run fish often terminated their migration for extended periods of time, in association with increased flows and decreased temperatures. Mid-run fish tended to migrate steadily upstream at a rate of 30-40 km/day. Late-run fish frequently ceased migrating or fell back downstream after migrating 10-200 km up the Willamette River or its tributaries; this appeared to be associated with warming water during summer and resulted in considerable mortality. Up to 40% of the adult salmon entering the Willamette River System above Willamette Falls (i.e. counted at the ladder) may die before reaching upriver spawning areas. Up to 10% of the fish passing up over Willamette Falls may fall-back below the Falls; some migrate to the Columbia River or lower Willamette River tributaries. If rearing conditions at hatcheries affect timing of adult returns because of different juvenile development rates and improper timing of smolt releases, then differential mortality in the freshwater segment of the adult migrations may confound interpretation of studies evaluating rearing practices.
