Book The Dynamics of the Parasitic Fauna of Different Forms of the Arctic Char Salvelinus Alpinus L in the Basin of Lake Azabach e

Download or read book The Dynamics of the Parasitic Fauna of Different Forms of the Arctic Char Salvelinus Alpinus L in the Basin of Lake Azabach e written by and published by . This book was released on 1985 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of the age changes in parasitic fauna calls for thorough analysis of this fauna's dependence on the morphological and ecological changes characterizing the successive stages of fish development. The differences in the parasitic fauna of various intraspecific forms of Arctic char (lake predators and benthophages, and brook and diadromous forms) inhabiting Lake Azabach'e and the Kamchatka River were earlier established and described. This study determined the changes in the parasitic fauna of different aged Arctic char depending on their food habits, using chars collected from 1969-71 and in 1973.

Book Genetic Variation in Cultured and Natural Populations of Arctic Charr Salvelinus Alpinus from North America microform

Download or read book Genetic Variation in Cultured and Natural Populations of Arctic Charr Salvelinus Alpinus from North America microform written by Tricia Anne Lundrigan and published by National Library of Canada = Bibliothèque nationale du Canada. This book was released on 2002 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The amount of genetic variation in aquaculture strains of North American Arctic charr (Salvelinus alpinus) was compared to that in natural populations using six microsatellite markers. Aquaculture strains originating from the Fraser River (Labrador), Nauyuk Lake and Tree River (Nunavut), and Lake Aleknagik (Alaska) showed less genetic variability than their wild source populations in terms of allelic diversity. but not necessarily in observed heterozygosity. Pairwise tests for genetic differentiation between populations were significant for all but three comparisons. These comparisons consisted of consecutive year classes of cultured Labrador and Nauyuk fish originating from the same wild collections. A neighbour joining tree based on microsatellite data grouped samples according to their geographic origin. Phylogenetic analysis of mitochondrial control region sequences from S.alpinus-S.malma did not always group samples thought to be conspecific. These results indicate that all hatchery strains and wild populations of Arctic charr- should not be considered equal and that small founding population sizes have contributed to reduced genetic variation in aquaculture strains"--Leaf before i.

Book Survey of Restriction Fragment Length Polymorphism Variation in Arctic Char Salvelinus Alpinus L Mitochondrial DNA

Download or read book Survey of Restriction Fragment Length Polymorphism Variation in Arctic Char Salvelinus Alpinus L Mitochondrial DNA written by and published by . This book was released on 1995 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarises results of an examination of the utility of restriction fragment length polymorphisms (RFLPs) to detect genetic variability in mitochondrial DNA (mtDNA) among stocks of Arctic char (Salvelinus alpinus). The report also includes laboratory protocols which have been adapted during the investigation. The researchers conducted a survey using 20 restriction endonuclease enzymes on 60 frozen samples of Arctic char from Lake Hazen, Craig Lake, and central Ellesmere Island in the Northwest Territories to determine the existence of polymorphisms in mtDNA and to assess whether RFLPs could be used to distinguish stocks in local geographical areas. A subset of five endonuclease enzymes was used to examine fresh samples of hatchery lineages of Arctic char originally from Storvatn in northern Norway, from Labrador, and from two locations in the Northwest Territories. This was done to increase the geographic area examined in the search for genetic variability.

Book The Lake Charr Salvelinus namaycush Biology Ecology Distribution and Management

Download or read book The Lake Charr Salvelinus namaycush Biology Ecology Distribution and Management written by Andrew M. Muir and published by Springer Nature. This book was released on 2021-03-03 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lake charr Salvelinus namaycush is a ubiquitous member of cold-water lake ecosystems in previously glaciated regions of northern continental U.S., Alaska, and Canada that often support important commercial, recreational, and subsistence fisheries. The lake charr differs from other charrs by its large size, longevity, iteroparity, top-predator specialization, reduced sexual dimorphism, prevalence of lacustrine spawning, and use of deepwater habitat. The species is remarkably variable in phenotype, physiology, and life history, some of which is reflected in its ecology and genetics, with as many as four morphs or ecotypes co-occurring in a single lake. The lake charr is often the top predator in these systems, but is highly adaptable trophically, and is frequently planktivorous in small lakes. The lake charr by their name highlights their common habitat, lakes both large and small, but often frequents rivers and occasionally moves into the Arctic Ocean. Movement and behaviour of lake charr are motivated by access to cool, well-oxygenated water, foraging opportunities, predator avoidance, and reproduction. Owing to their broad distribution and trophic level, the lake charr serves as a sentinel of anthropogenic change. This volume will provide an up-to-date summary of what is currently known about lake charr from distribution to genetics to physiology to ecology. The book provides a compilation and synthesis of available information on the lake charr, beginning with an updated distribution and a revised treatment of the paleoecology of the species. Understanding of ecological and genetic diversity and movement and behaviour of the species has advanced remarkably since the last major synthesis on the species over 40 years ago. Mid-sections of the book provide detailed accounts of the biology and life history of the species, and later sections are devoted to threats to conservation and fishery management practices used to ensure sustainability. A new standard lake charr-specific terminology is also presented. The book will be a valuable reference text for biologists around the world, ecologists, and fishery managers, and of interest to the angling public.
