Download or read book Using Genetic Tools to Inform Management and Study Local Adaptation in Pacific Salmon written by Wesley Alan Larson and published by . This book was released on 2015 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic analysis represents a powerful tool for informing management and studying adaptation in wild populations. For example, genetic tools can be used to delineate conservation units, assign individuals of unknown ancestry back to their populations of origin, and identify genes that are important for local adaptation. The overall goal of my thesis was to apply genetic tools to improve population-specific management and identify the genetic basis of local adaptation in Pacific salmon. Pacific salmon (Oncorhynchus sp.) return to their natal spawning habitats with high fidelity, promoting the formation of distinct populations that are highly adapted to their local environment. Pacific salmon are also an extremely important economic, cultural, and subsistence resource. These characteristics make Pacific salmon ideal candidates for population-specific management and facilitate the study of local adaptation. My dissertation consists of six chapters divided into two major themes. The first three chapters focus on applied research questions aimed at developing and utilizing genetic tools to improve management of Chinook salmon (Oncorhynchus tshawytscha), and the last three chapters focus on understanding the genetic basis of local adaptation in sockeye salmon (Oncorhynchus nerka). In chapter one, we used an existing genetic baseline to elucidate the migration patterns of Chinook salmon in the marine environment. Chapters two and three explored the use of genomics in a management context, applying data from thousands of genetic markers to develop novel resources that will aid in the conservation of Chinook salmon from western Alaska. For chapter four, we investigated patterns of selection at the major histocompatibility complex (MHC) in populations of sockeye salmon from the Wood River basin in southwestern Alaska. In chapter five, we constructed a genetic linkage map and conducted QTL analysis in five families of sockeye salmon. Finally, in chapter six we merged the linkage map with population data to study the genomic basis of adaptive divergence among three ecotypes of sockeye salmon from the Wood River basin. Taken together, these studies highlight the utility of genetic tools, especially genomics, for improving management and studying local adaptation in Pacific salmon.

Available in PDF, EPUB and Kindle. Book excerpt: It has previously been documented that naturally spawning, female fall-run chinook salmon (Oncorhynchus tshawytscha) from the Hanford Reach on the Columbia River carried a male-linked genetic marker, OtY1. The primary objective of this study was to investigate the spatial and temporal nature of this observation by sampling adults from the Hanford Reach and two other new sites, the lower Yakima River and at Ives Island below Bonneville Dam, in sequential years (2001 and 2002). A hatchery population on the Columbia River (Priest Rapids Hatchery) was sampled too. A total of 364 male and 359 female fall-run chinook salmon were sampled over the two spawning seasons from all sites. Detection of the male-linked genetic marker OtY1 in male fish was found to be 100% consistent with the phenotypic male sex in all populations sampled. A variable proportion of females from all sites tested positive for OtY1. This ranged from 67% at Ives Island in 2001 to 0% at the Priest Rapids Hatchery in 2002. A significant reduction of OtY1 incidence in females sampled in 2002 compared to 2001 emerged at all sites. A second objective sought evidence that a YY genotype might exist in the populations sampled. A real-time PCR method based on the growth hormone pseudogene (GHp), another male-linked chinook salmon genetic marker, was developed and tested to determine whether a YY genotype might be detected. The experimental variability between different XY individuals precluded its use to discriminate an YY from an XY genotype. During associated work on new chinook salmon sex linked genetic markers a new Y chromosome linked genetic marker, OtY2, was discovered.

Hargrove and published by . This book was released on 2019 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes life history and genetic diversity information for wild adult steelhead and spring/summer Chinook Salmon sampled at Lower Granite Dam and later detected in a Distinct Population Segment (DPS) or Evolutionarily Significant Unit (ESU) population in the Snake River basin for the 01/01/2018 to 12/31/2018 reporting period. This reporting period covers analysis of individuals crossing Lower Granite Dam in spawn year 2018. A total of 2,306 steelhead and 1,372 Chinook Salmon were sampled at Lower Granite Dam, 905 and 704 of which were subsequently identified at a PIT tag detection location elsewhere in the Snake River basin. Panels of up to 379 SNPs were genotyped at both Idaho Department of Fish and Game's Eagle Fish Genetics Lab and its collaborating laboratory, 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. 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.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors used protein electrophoresis to examine genetic relationships among samples of sockeye salmon and kokanee (Oncorhynchus nerka) from the Snake River basin. A few collections from elsewhere in the Pacific Northwest were also included to add perspective to the analysis. After combining temporal samples that did not differ statistically within and between years, 32 different populations were examined for variation at 64 gene loci scored in all populations. Thirty-five (55%) of these gene loci surveyed were polymorphic in at least one population. Average heterozygosities were relatively low (0.006--0.041), but genetic differentiation among populations was pronounced: the value of Wright's F[sub ST] of 0.244 is higher than has been reported in any other study of Pacific salmon.

This book was released on 2016 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific salmon (Oncorhynchus spp.) serve an important social and economic role in western North America. Despite historical abundance, native salmonids are now at risk of extinction throughout much of their native range. The accurate characterization of historic range, population size, and gene flow is essential for the development of successful conservation strategies. Therefore, conservation disciplines may look to the past to inform the future. One framework for such investigations is phylogeography, which examines geographical and genealogical connections in an effort to understand the evolutionary history of organisms. Another avenue is the study of genetic data from temporally diverse samples, which facilitates the direct observation of a genetic history.

Download or read book Chinook Salmon and Steelhead Genotyping for Genetic Stock Identification at Lower Granite Dam written by John S. Hargrove and published by . This book was released on 2020 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes progress in the development and implementation of genetic stock identification (GSI) in the Snake River basin for natural-origin steelhead and spring/summer Chinook Salmon for the 01/01/2019 to 12/31/2019 reporting period. Four objectives for the GSI project are addressed in this report: 1) the maintenance and evaluation of single nucleotide polymorphism (SNP) panels for high-throughput genotyping of steelhead and Chinook Salmon in the Snake and Columbia river basins; 2) the updating, maintenance, and testing of SNP baselines to describe genetic variation and for use as a reference in conducting GSI for both species; 3) the implementation of GSI to estimate genetic stock composition and life history diversity of steelhead and spring/summer Chinook Salmon passing Lower Granite Dam (LGR); and 4) the summarization of life history and genetic diversity information for steelhead and spring/summer Chinook Salmon detected at PIT tag detection systems. For both species, panels of up to 379 SNPs have been in use for GSI and parentage-based tagging (PBT) at both Idaho Department of Fish and Game’s Eagle Fish Genetics Lab, and its collaborating laboratory, the Columbia River Inter-Tribal Fish Commission’s Hagerman Genetics Lab. Steelhead SNP baseline version v3.1 consists of 45 collections and 5,967 individuals. Chinook Salmon SNP baseline v3.1 consists of 30 collections and 4,356 individuals. SNP baselines are used to describe genetic diversity and structure of natural-origin populations throughout the Snake River. Based on population structure we have defined 10 genetic stocks for steelhead and 7 genetic stocks for Chinook Salmon for GSI analysis at LGR. We summarize GSI results for returning adults and emigrating juveniles during 2018-2019 at LGR using v3.1 baselines as reference. The information presented in this report provides critical data for viable salmonid population (VSP) monitoring of the Snake River steelhead DPS and the Snake River spring/summer Chinook Salmon ESU.

Download or read book The Genetic Structure of Chinook and Coho Salmon Populations in California, with a Note on the Genetic Variability in Sturgeon (Acipenseridae). written by Devin Michael Bartley and published by . This book was released on 1987 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Populations of chinook, Oncorhynchus tshawytscha, and coho salmon, O. kisutch, from Northern California and four species of North American sturgeon were analyzed by horizontal starch-gel electrophoresis. The products of 53 gene loci from 27 enzyme systems were used to characterize the genetic structure of 35 groups of hatchery and wild chinook salmon. The distribution of specific alleles, cluster analysis based on genetic identities, analyses of gene flow, and gene diversity analyses indicated that groups of chinook salmon from the three major river drainages in California were genetically differentiated. The products of 45 gene loci from 21 enzyme systems were used to characterize the genetic structure of 27 groups of coho salmon. Most of the observed genetic variation was due to rare alleles occurring in only a few groups of salmon. No obvious association of specific alleles with geographic area was observed and the low level of genetic variability made patterns of genetic structure or associations among the groups of coho salmon difficult to determine. The application of biochemical-genetic analyses to the management of chinook and coho salmon fisheries was addressed. A comparison of hatchery groups of chinook and coho salmon with wild groups in the same area revealed that hatchery stocks generally reflect the genetic structure of the local populations. The genetic differentiation of chinook salmon by drainage could provide fishery scientists with a means to identify specific groups of chinook salmon. The application of this technique to manage coho salmon populations is problematic at the present given the seemingly random distribution of alleles and the low levels of genetic variability. The products of seven gene loci were used to identify hybridization between chinook and coho salmon in a collection of salmon from a tributary to the Trinity River. The implications of a group of hybrid fish in the wild were discussed in terms of genetic resource conservation and disease transmission. The products of 20 gene loci were used to characterize the genetic structure and relationship of four species of sturgeon: Acipenser transmontanus, A. medirostris, A. fulvescens, and A. brevirostrum. Fixed allelic differences existed among the four species at several gene loci and each species could be unambiguously identified by its genetic profile.
