Available in PDF, EPUB and Kindle. Book excerpt: Most of the economically important traits in animal breeding programs are quantitative in nature. Detecting major genes and/or blocks of genes influencing these traits has been made possible by the availability of hypervariable DNA markers. In this study, phenotypic variations related to growth and body girth in the two domesticated strains of Arctic charr(Salvelinus alpinus L.) at Icy Waters Ltd. (Whitehorse, Yukon, Canada) were examined and then quantitative trait loci for growth were identified using a genome wide scan approach. Twelve crosses involving the pure strains (Tree River and Yukon GoldTM), the reciprocal hybrids, and the reciprocal backcrosses were set up with ten families per cross. After 18 months of rearing in the hatchery environment under identical culture conditions, it was observed that backcrosses with a 75% Tree River genome contribution ((YGfxTRm)fxTRm) grew fastest and possessed greatest variance. A total of 198 highly polymorphic microsatellite markers, from various salmonid species, covering 41 linkage groups on the current Arctic charr linkage map were tested for a genome scan. Sixty two highly polymorphic markers were chosen to perform a genome wide scan on a full-sib backcross family, namely 6-10, to detect genetic factors responsible for the variation of growth in Arctic charr. These markers cover 28 of the 46 linkage groups in the currently available, low-resolution genetic map of Arctic charr. Results from a transmission disequilibrium test (TDT) indicate a significant association (0.001

Available in PDF, EPUB and Kindle. Book excerpt: This important book draws together, for the first time, a vastwealth of information on all major aspects of the farming of Arcticcharr, a highly prized and commercially valuable salmonid. Theauthor, Gavin Johnston who has many years' experience of farmingArctic charr, teaching about and researching the species, hasproduced a book that is a landmark publication and an essentialpurchase for all those involved with the species. The book is broadly divided into three sections. The firstsection covers Arctic charr interactions with humans and thecharr's biological requirements for culture. Section two is apractical guide to the art and science of early-rearing Arcticcharr; a hands on application of current knowledge in Arctic charraquaculture. The final section of the book focuses on thecommercial production of Arctic charr, providing cutting-edgeinformation for all those involved in the exploitation of thisvaluable species. Arctic Charr Aquaculture is an essential purchase foranyone involved in, or considering involvement in farming of thisspecies. Farm managers and other personnel in fish farms andexperimental aquaculture units, fish and aquatic biologists willfind a huge amount of useful data in this book. Libraries in alluniversity departments and research establishments whereaquaculture, fisheries and fish biology are studies and taughtshould have copies of this book on their shelves. This book bringstogether for the first time the knowledge needed to farm and marketArctic Charr. Part One is an overview of Arctic Charr aquaculturebeginning with the history and development of Charr aquaculture,the biological attributes of Arctic Charr, the physicalrequirements for growth and commercial production requirements.Other chapters are devoted to Charr health, nutrition and feeding.Part Two is a practical guide for the producer operating an ArcticCharr farm either as a vertically integrated operation or asdiscrete hatcheries and grow out farms. Part Three is devoted tothe business of commercially producing Arctic Charr, and althoughit deals specifically with Charr it also covers many businessaspects of farming relevant to any fish species under cold watercultivation. It covers farm business management, the economics andfinance of Arctic Charr farming, marketing Charr products and aclosing section on how to avoid the pitfalls which others includingthe author have experienced.

Book excerpt: There is considerable global interest in the culture of finfish species both for cold and warm water aquaculture development and growth. Essential information on the biology, domestication and aquacultural characteristics of a wide selection of novel and established species is provided in the form of technical sheets, species descriptions and information on current rearing practices, making this a must-have reference in the field of aquacultural science. The book also offers a basic framework in order to support investment strategies for research and developement efforts aimed at the emergence of a profitable finfish aquaculture industry and presents a rationale for species diversification, different approaches to species selection and basic economical and market considerations governing the launch of strategic development and commercialization efforts.

Download or read book Biologie des poissons d eau douce europ ens 2e d written by BRUSLÉ Jacques and published by Lavoisier. This book was released on 2013-07-01 with total page 802 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biologie des poissons d’eau douce européens, par son champ d’étude vaste et ambitieux, est un ouvrage de référence en ichtyologie dulçaquicole. Couvrant l’ensemble des aspects écologiques, écobiologiques, écophysiologiques et éthologiques, il dresse une présentation détaillée de 88 espèces auto- ou allochtones : morphologie, anatomie, distribution géographique, habitats, modes de vie et activités physiologiques. 453 autres espèces sont également répertoriées. Cette 2e édition a été largement revue et augmentée, compte tenu de l’importance des données scientifiques récentes. Outre des compléments utiles portant sur les habitats et les modes de vie, cet ouvrage s’enrichit des nombreux apports génétiques qui ont parfois « révolutionné » les concepts anciens relatifs aux origines paléo-historiques et paléo-géographiques des espèces. Des extensions ou des réductions de répartitions géographiques ont été consécutives à des transferts d’origine anthropique, à des dégradations physiques et chimiques et à la récente influence du Global Warming, sans oublier les changements de statut dans le domaine de la systématique. Au fil d’un livre d’une grande rigueur scientifique, abondamment illustré (dont 64 aquarelles originales et plus de 70 cartes géographiques pertinentes) et complété par un glossaire et une importante bibliographie, le lecteur abordera la connaissance des poissons européens d’une façon à la fois originale et attrayante. Cet ouvrage s’adresse à un large public : étudiants de 2e et 3e cycles en biologie, zoologie, écologie, hydrobiologie, environnement, ingénieurs et techniciens chargés de l’aménagement, de la gestion, de la qualité et de la protection des milieux aquatiques (services vétérinaires, de l’Environnement, de l’Agriculture, de l’Équipement…) auxquels il apportera les bases fondamentales nécessaires à leur action, et plus largement tous les passionnés d’ichtyofaune.

Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture technology has been evolving rapidly over the last two decades, led by an increasingly skilled cadre of researchers in developing countries. Rather than copying, or adapting work done in industrialized countries to their situations, these scientists are moving aquaculture research out of the box to explore species and production systems relevant to their natural resources, economies and social institutions. Studies from India, Latin America, the Middle East and Africa are highlighted in this collection of papers, covering the entire gamut of aquaculture science from comparison of tilapia breeds, novel feed ingredients for indigenous species, improving disease resistance, water-use efficiency, traditional farming systems, spatial planning and economics. More than a how-to book, this volume introduces the researchers and institutions leading the development of aquaculture as it expands into new frontiers. This book was based on a special issue of the Journal of Applied Aquaculture.
