The Genetic Structure of Chinook and Coho Salmon Populations in California, with a Note on the Genetic Variability in Sturgeon (Acipenseridae).

Category : Acipenser

Pages : 432
Book Description
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.

Biochemical Genetic Variation Among Selected Populations of Chinook Salmon (Oncorhynchus Tshawytscha) in Oregon and Washington
Author: Anne Christine Kristiansson
Publisher:
ISBN:
Category : Chinook salmon
Languages : en
Pages : 58
Book Description
Biochemical variation in 12 different chinook populations, sampled from 10 hatcheries along the Columbia River and the Oregon coast, was studied with starch gel electrophoresis. An index was used to describe the genetic differences between pairs of populations. Differences were observed between spring and fall chinook and between Columbia River and Oregon coastal populations. Variation in inbreeding coefficients, calculated at four polymorphic loci, indicated that natural selection may alter the frequency of certain phenotypes.

Genetics of Subpolar Fish and Invertebrates
Author: Anthony J. Gharrett
Publisher: Springer Science & Business Media
ISBN: 9400709838
Category : Science
Languages : en
Pages : 457
Book Description
Fisheries genetics researchers will find invaluable the thirty-eight peer-reviewed contributions in this book, presented at the 20th Lowell Wakefield Fisheries Symposium "Genetics of Subpolar Fish and Invertebrates," held in May 2002 in Juneau, Alaska. Looming over concerns of lost fisheries stocks and persistent erosion of genetic variability are predictions of global warming, which may further tax genetic resources. One consequence is an increased reliance on genetic applications to many aspects of fisheries management, aquaculture, and conservation. The contributions in this book are important to modern fisheries science and genetics, and illustrate the evolution of the field over the past decade. The improved technology provides tools to address increasingly complicated problems in traditional applications and ecological and behavioral studies. The union between molecular and quantitative genetics, where many of the major questions about population structure and evolution remain unanswered, will also benefit from the new technologies.
