Available in PDF, EPUB and Kindle. Book excerpt: Introduction to the General Principles of Aquaculture provides novice aquaculturists with an overview of the aquaculture industry so you may proceed successfully in academic studies or commercial ventures. The authors furnish you with insight into the history and development of aquaculture and cover the subjects of natural production versus aquaculture, the aquatic environment, energy requirements of and relationships in aquaculture systems, important components of aquaculture systems, selection of aquaculture species, major cultured species and their distribution, global aquaculture production, a comparison of agriculture and aquaculture, and those factors promoting and constraining aquaculture. The book is liberally illustrated so that students and laymen are able to visualize systems and species. Furthermore, tables and figures are used throughout to emphasize important points, facts, and methods. As an introductory text, it emphasizes several aspects of aquaculture that must be understood by those new to the industry. These aspects include water quality, species of importance around the world, and current and projected aquaculture production on a global basis. The important components of any aquaculture system are also covered in some detail--biological factors, technical-biological factors, technical-economic factors, production cost factors, socioeconomic factors, and species selection factors. Laypersons considering aquaculture as an investment and students considering aquaculture as a career, but who have no real background in agriculture and fisheries sciences,will find this book to be a key information source. Introduction to the General Principles of Aquaculture is written with the global market in mind and instructors will find it to be a useful introductory text at the undergraduate level. Persons in advisory capacities such as County Extension Agents, extension service specialists and bureaucrats in various arms of government who hav

Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture has become of the fastest growing segments of agriculture around the world, but until recently many people have been unaware of its existence. The practice of raising fish is centuries old with a rich history of techniques and scientific advances. The History of Aquaculture traces the development of fish farming from its ancient roots to the technologically advanced methods of today. The History of Aquaculture is a comprehensive history of captive fish production from its small scale prehistoric roots through to the large-scale industrialized practices of today. Thirteen chapters take readers chronologically through the evolution of this important discipline. Chapters cover key periods of advancement and trace changes in the field from subsistence fish farming in the Middle Ages through the efforts to build global capacity for fish production to meet the needs of the world's ever growing population. Informative and engaging, The History of Aquaculture will broadly appeal to aquaculture scientists, researchers, professionals, and students. Special Features: Comprehensive history of advances in aquaculture production from prehistoric origins to industrialized practices Written by a revered scientists with decades of experience working in the aquaculture field Engaging and informative it will broadly appeal to individuals involved in all facets of aquaculture

Download or read book Selective Breeding in Aquaculture an Introduction written by Trygve Gjedrem and published by Springer Science & Business Media. This book was released on 2010-03-17 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: The foundation of quantitative genetics theory was developed during the last century and facilitated many successful breeding programs for cultivated plants and t- restrial livestock. The results have been almost universally impressive, and today nearly all agricultural production utilises genetically improved seed and animals. The aquaculture industry can learn a great deal from these experiences, because the basic theory behind selective breeding is the same for all species. The ?rst published selection experiments in aquaculture started in 1920 s to improve disease resistance in ?sh, but it was not before the 1970 s that the ?rst family based breeding program was initiated for Atlantic salmon in Norway by AKVAFORSK. Unfortunately, the subsequent implementation of selective breeding on a wider scale in aquaculture has been slow, and despite the dramatic gains that have been demonstrated in a number of species, less than 10% of world aquaculture production is currently based on improved stocks. For the long-term sustainability of aquaculture production, there is an urgent need to develop and implement e- cient breeding programs for all species under commercial production. The ability for aquaculture to successfully meet the demands of an ever increasing human p- ulation, will rely on genetically improved stocks that utilise feed, water and land resources in an ef?cient way. Technological advances like genome sequences of aquaculture species, and advanced molecular methods means that there are new and exciting prospects for building on these well-established methods into the future.

This book was released on 2006 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The FAO Yearbook of Fishery Statistics - Capture production is a compilation of statistics on nominal catches of fish, crustaceans, molluscs and other aquatic animals, residues and plants. The statistics are presented by country or territory, species, major fishing area and year, and for various aggregations. In order to provide complete coverage of catch statistics throughout the world, where officially reported national statistics are lacking or are considered unreliable, FAO makes estimates based on the best information available.

Download or read book Selection and Breeding Programs in Aquaculture written by Trygve Gjedrem and published by Springer Science & Business Media. This book was released on 2005-07-10 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although aquaculture as a biological production system has a long history, systematic and efficient breeding programs to improve economically important traits in the farmed species have rarely been utilized until recently, except for salmonid species. This means that the majority of aquaculture production (more than 90 %) is based on genetically unimproved stocks. In farm animals the situation is vastly different: practically no terrestrial farm production is based on genetically unimproved and undomesticated populations. This difference between aquaculture and livestock production is in spite of the fact that the basic elements of breeding theory are the same for fish and shellfish as for farm animals. One possible reason for the difference is the complexity of reproductive biology in aquatic species, and special consideration needs to be taken in the design of breeding plans for these species. Since 1971 AKVAFORSK, has continuously carried out large scale breeding research projects with salmonid species, and during the latest 15 years also with a number of fresh water and marine species. Results from this work and the results from other institutions around the world have brought forward considerable knowledge, which make the development of efficient breeding programs feasible. The genetic improvement obtained in selection programs for fish and shellfish is remarkable and much higher than what has been achieved in terrestrial farm animals.

Download or read book Fishes in Lagoons and Estuaries in the Mediterranean 1 written by Mohamed Hichem Kara and published by John Wiley & Sons. This book was released on 2019-02-06 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lagoons and estuaries are transition spaces between earth and sea. Beyond their expanse, geographic repartition, geomorphological, hydroclimatic and ecobiological diversity and biodiversity, they play an important role in regional economies and are some of the ecosystems most vulnerable to global change. Reinforced by numerous references, this book studies Mediterranean lagoonal and estuarine fishes whose diversity largely depends on the composition of neighboring marine and continental ichtyofauna. The authors describe their morphological, biological, ecological and behavioral characteristics by evoking their distinctive features and differences with their marine or freshwater homologues. Their adaptation strategies, elucidated thanks to recent advances in morphology, genetics and molecular biology, are recognized as a major advantage in the context of climate change. This book is for natural environment managers, engineers, teachers, students and researchers.
