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.

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.
Download or read book Seasonal Patterns of Growth in Arctic Charr Salvelinus Alpinus L written by Gabrielle Grenier and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arctic Charr (Salvelinus alpinus L.) are phenotypically variable with multiple life history eco-morphotypes. The mechanism determining life history trajectory remains undiscovered. At maturity, anadromous individuals have greater seasonality in their growth and feeding relative to their resident conspecifics. To determine if lifelong seasonal and annual growth patterns differ between resident and anadromous individuals I measured otolith increment widths with a semi-automated method. I found that there has been a linear increase in growth in Arctic Charr between 1990 and 2015. Additionally, anadromous Arctic Charr have greater growth and seasonality in their growth relative to their resident conspecifics and these patterns are consistent at all ages. Finally, a probable life history trajectory can be assigned to Arctic Charr based on the seasonal growth pattern in the first year of life. In conclusion, further studies examining factors influencing early development are essential to elucidate the mechanism behind life-history trajectory in Arctic Charr.

Download or read book Aquaculture Nutrition written by Daniel L. Merrifield and published by John Wiley & Sons. This book was released on 2014-10-20 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manipulation of the microbial gut content of farmed fishes and crustaceans can have a marked effect on their general health, growth, and quality. Expertly covering the science behind the use of prebiotics and probiotics this landmark book explains how the correct manipulation of the gut flora of farmed fishes and crustaceans can have a positive effect on their health, growth rates, feed utilization, and general wellbeing. Aquaculture Nutrition: Gut Health, Probiotics and Prebiotics provides a comprehensive overview of the current knowledge of the gut microbiomes of fish and their importance with respect to host-fish health and performance, providing in-depth, cutting-edge fundamental and applied information. Written by many of the world’s leading authorities and edited by Dr Daniel Merrifield and Professor Einar Ringø, this important book discusses in detail the common mechanisms for modulating microbiomes, particularly at the gut level (e.g. probiotics, prebiotics and synbiotics). The book is a key resource for an understanding of the historical development of these products, their known mechanisms of action and their degree of efficacy as presently demonstrated in the literature. The fundamental material provided on the gut microbiota itself, and more broad aspects of microbe-live feed interactions, provide essential reading for researchers, academics and students in the areas of aquaculture nutrition, fish veterinary science, microbiology, aquaculture, fish biology and fisheries. Those involved in the development and formulation of aquaculture feeds and those with broader roles within the aquaculture industry will find a huge wealth of commercially-important information within the book’s covers. All libraries in universities and research establishments where biological sciences, nutrition and aquaculture are studied and taught, should have copies of this excellent book on their shelves.
Download or read book Principles of Salmonid Culture written by W. Pennell and published by Elsevier. This book was released on 1996-10-11 with total page 1071 pages. Available in PDF, EPUB and Kindle. Book excerpt: As salmonids have been reared for more than a century in many countries, one might expect that principles are well established and provide a solid foundation for salmonid aquaculture. Indeed, some of the methods used today in salmonid rearing are nearly identical to those employed one hundred years ago. Areas of salmonid research today include nutrition, smolt and stress physiology, genetics and biotechnology.The purpose of this book is to provide a useful synthesis of the biology and culture of salmonid fishes. The important practices in salmonid culture as well as the theory behind them is described. This volume will be of interest to students, researchers, fisheries biologists and managers as well as practising aquaculturists.

This book was released on 2013-03-09 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salvelinus species are one of the most thoroughly studied groups of fishes. Many reasons explain this intense interest in charr biology. Charrs have a Holarctic distribution encompassing many Asian, North American, and European countries and occupy diverse marine and freshwater environments. Furthermore, the current distribution of charr includes areas that were directly influenced by climate and topographic change associated with the many Pleistocene glaciations. Undoubtedly, these conditions have promoted much of the tremendous morphological, ecological, and genetic variability and plasticity within Salvelinus species and they make charr very good models to study evolutionary processes 'in action'. Many charr species also exhibit demographic characteristics such as slow growth, late maturity, and life in extreme environments, that may increase their susceptibility to extinction from habitat changes and overexploitation, especially in depauperate aquatic habitats. This vulnerability makes understanding their biology of great relevance to biodiversity and conservation. Finally, charr are of great cultural, commercial, and recreational significance to many communities, and their intimate linkage with human societies has stimulated much interest in this enigmatic genus. This volume comprises a selection of papers presented at the fourth International Charr Symposium held in Trois-Rivières (Québec, Canada), from 26 June to 1 July 2000. It includes 31 papers on ecological interactions and behaviour, trophic polymorphism, movement and migration, ecophysiology and evolutionary genetics, ecological parasitology, environmental stress and conservation. These studies cannot cover all recent developments in the ecology, behaviour and conservation of Salvelinus species, but collecting them into a special volume should bring attention to current research on this important genus and stimulate further work on Salvelinus species.
