A thorough study of the principles and practices of aquaculture, the book reflects the state of the art in pond aquaculture and incorporates recent advances that have changed the science in the last decade or so. It provides a thorough review of the many methods, techniques, and ideas that comprise this complex and fascinating area of study.
Book Synopsis Nature of Fish Growth Hormones by : Sekar Megarajan
Download or read book Nature of Fish Growth Hormones written by Sekar Megarajan and published by Delve Publishing. This book was released on 2017-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth rate is a primary trait of interest in most finfish selection programs and is intrinsically linked to productivity and profitability of finfish aquaculture industry in several parts of the world. Search for candidate genes influencing growth has been a major focus of research in aquaculture and several such genes have been isolated from the fish genome and their effects are quantified. Growth hormone genes have been studied extensively in many species because of its potential in enhancing the growth rate of fishes in aquaculture. The identified growth hormone gene in most of the fishes is roughly 1.5 kb long, with the protein coding region divided in to four to five blocks (exons) representing less than one third length of the genomic region. Growth hormone (GH) is a single chain polypeptide that plays a major role in the growth development of vertebrates. It is the main regulator of postnatal somatic growth and stimulates anabolic processes such as cell division, skeletal growth and protein synthesis. In addition, growth hormone is also involved in the regulation of fat oxidation, inhibition of glucose transport to peripheral tissues and regulation of ribosome translational activity, which in turn influences protein synthesis. Presently, the importance of GH as a candidate gene for studies of genetic variation in connection with growth traits and potential natural marker for studies of evolutionary relationship of various fishes has been demonstrated. Its potential application in the growth traits and fish evolution studies has been an active area of research. Natural growth rates of organisms have evolved to provide maximum fitness in wild environments and therefore, enhancement of natural growth rate of fish in aquaculture has been extensively explored, with gains arising from improvements in husbandry, nutrition, and genetical selection. Growth enhancement can be advantageous for aquaculture by shortening production time, and enhancing feed conversion efficiency. Therefore, endocrine approaches in controlling growth have been extensively explored. Several studies have demonstrated the efficacy of mammalian GH in the acceleration of growth of various species. In fish, GH administration by various modes of delivery like injection, and oral administration of hormones has been successfully studied. These studies have suggested that the exogenous growth hormone enhances fish growth by stimulating appetite and improving feed conversion. It is clearly understood that growth hormone plays major role in aquaculture industry by increasing the growth. Therefore, knowing the different aspects of growth hormone is very much essential for the researchers aim for growth enhancement in fishes.

Download or read book The State of World Fisheries and Aquaculture 2018 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-07-10 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2018 edition of The State of World Fisheries and Aquaculture emphasizes the sector’s role in achieving the 2030 Agenda for Sustainable Development and the Sustainable Development Goals, and measurement of progress towards these goals. It notes the particular contributions of inland and small-scale fisheries, and highlights the importance of rights-based governance for equitable and inclusive development. As in past editions, the publication begins with a global analysis of trends in fisheries and aquaculture production, stocks, processing and use, trade and consumption, based on the latest official statistics, along with a review of the status of the world’s fishing fleets and human engagement and governance in the sector. Topics explored in Parts 2 to 4 include aquatic biodiversity; the ecosystem approach to fisheries and to aquaculture; climate change impacts and responses; the sector’s contribution to food security and human nutrition; and issues related to international trade, consumer protection and sustainable value chains. Global developments in combating illegal, unreported and unregulated fishing, selected ocean pollution concerns and FAO’s efforts to improve capture fishery data are also discussed. The issue concludes with the outlook for the sector, including projections to 2030. As always, The State of World Fisheries and Aquaculture aims to provide objective, reliable and up-to- date information to a wide audience, including policy-makers, managers, scientists, stakeholders and indeed all those interested in the fisheries and aquaculture sector.

Download or read book Fish Ecophysiology written by J.C. Rankin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the fishes. a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes. ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts. in the deep sea. in the cold antarctic. and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specialisations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins. sailfish and warm-blooded tunas, air-breathing in catfish and lungfish. parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious. delicious and diverse food. Rational exploi management of our global stocks of fishes must rely upon a detailed tation and and precise insight of their biology. The Chapman [.,. Hall Fish and Fisheries series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology. zoology. ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non-specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of IIsh and t1sheries.

Book Synopsis Aquaculture in China by : Jian-Fang Gui
Download or read book Aquaculture in China written by Jian-Fang Gui and published by John Wiley & Sons. This book was released on 2018-03-28 with total page 1074 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish have been a major component of our diet and it has been suggested that fish/seafood consumption contributed to the development of the human brain, and this together with the acquisition of bipedalism, perhaps made us what we are. In the modern context global fish consumption is increasing. However, unlike our other staples, until a few years back the greater proportion of our fish supplies were of a hunted origin. This scenario is changing and a greater proportion of fish we consume now is of farmed origin. Aquaculture, the farming of waters, is thought to have originated in China, many millennia ago. Nevertheless, it transformed into a major food sector only since the second half of the last century, and continues to forge ahead, primarily in the developing world. China leads the global aquaculture production in volume, in the number of species that are farmed, and have contributed immensely to transforming the practices from an art to a science. This book attempts to capture some of the key elements and practices that have contributed to the success of Chinese aquaculture. The book entails contributions from over 100 leading experts in China, and provides insights into some aquaculture practices that are little known to the rest of the world. This book will be essential reading for aquaculturists, practitioners, researchers and students, and planners and developers.

Book excerpt: "Before prehistoric humans began to cultivate grain, they had three main methods of acquiring food: hunting, gathering, and fishing. Hunting and gathering are no longer economically important, having been replaced by their domesticated equivalents, ranching and farming. But fishing, humanity's last major source of food from the wild, has grown into a worldwide industry on which we have never been more dependent. In this history of fishing--not as sport but as sustenance--archaeologist and writer Brian Fagan argues that fishing rivaled agriculture in its importance to civilization. [He] tours archaeological sites worldwide to show ... how fishing fed the development of cities, empires, and ultimately the modern world"--Jacket flaps.

Download or read book Fish Energetics written by Peter Tytler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.
Book Synopsis Introductory Fisheries Analyses with R by : Derek H. Ogle
Download or read book Introductory Fisheries Analyses with R written by Derek H. Ogle and published by CRC Press. This book was released on 2016-01-05 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: A How-To Guide for Conducting Common Fisheries-Related Analyses in R Introductory Fisheries Analyses with R provides detailed instructions on performing basic fisheries stock assessment analyses in the R environment. Accessible to practicing fisheries scientists as well as advanced undergraduate and graduate students, the book demonstrates the flexibility and power of R, offers insight into the reproducibility of script-based analyses, and shows how the use of R leads to more efficient and productive work in fisheries science. The first three chapters present a minimal introduction to the R environment that builds a foundation for the fisheries-specific analyses in the remainder of the book. These chapters help you become familiar with R for basic fisheries analyses and graphics. Subsequent chapters focus on methods to analyze age comparisons, age-length keys, size structure, weight-length relationships, condition, abundance (from capture-recapture and depletion data), mortality rates, individual growth, and the stock-recruit relationship. The fundamental statistical methods of linear regression, analysis of variance (ANOVA), and nonlinear regression are demonstrated within the contexts of these common fisheries analyses. For each analysis, the author completely explains the R functions and provides sufficient background information so that you can confidently implement each method. Web Resource The author’s website at http://derekogle.com/IFAR/ includes the data files and R code for each chapter, enabling you to reproduce the results in the book as well as create your own scripts. The site also offers supplemental code for more advanced analyses and practice exercises for every chapter.
