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 2000 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The publication contains the 17 invited papers which were presented and discussed at the Expert Consultation on Sustainable Fishing Technologies and Practices held in St. John's, Newfoundland, Canada (1-6 March 1998). The papers cover four broad categories. The first section deals with the methodologies for development and assessment of the effectiveness of fishing gears. The second section deals with the review of impact assessments of fishing activities on the marine habitat. Representative examples of sustainable fishing technologies and practices are dealt with in the third part and finally the fourth and final section deals with the introduction and implementation of sustainable technologies and practices.

This book was released on 2012-12-06 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until the First Edition of World Fish Farming: Cultivation and Econom ics was published several years ago, there was little or no economic and technical information on commercial aquaculture either by countries or by species. I tried at that time to partially fill the gap in the literature. In this Second Edition, I have updated data originally presented and increased the scope by adding new countries. New trout data have been added for 10 western European countries; sections on cost of production of food-sized catfish and fingerlings in the USA; new and improved chapters for Japan, Hungary, Indonesia, the Philippines, and the United Kingdom; and com pletely new chapters pertaining to Poland, Thailand, and Czechoslovakia have all been added to this edition. The book now includes 31 countries, including all major producing ones. Between 5. 5 and 6. 0 million metric tons of finfish, shrimp, and crayfish cultured production are represented, which accounts for about 909c of the world's total. The People's Republic of China and the USSR, as well as countries on the continents of Europe, Asia, North America, and Oceania, are represented. Because of only minimal reported cultured fish production in Africa and South America, these continents have been omitted. Also, according to information received from New Zealand, there is no culturing offish in that country other than for restocking of public waters. More than 100 species of cultured fish, seven species of shrimp and prawns, and six species of crayfish are discussed.

Book excerpt: The Arthur M. Sackler Colloquia of the National Academy of Sciences address scientific topics of broad and current interest, cutting across the boundaries of traditional disciplines. Each year, four or five such colloquia are scheduled, typically two days in length and international in scope. Colloquia are organized by a member of the Academy, often with the assistance of an organizing committee, and feature presentations by leading scientists in the field and discussions with a hundred or more researchers with an interest in the topic. Colloquia presentations are recorded and posted on the National Academy of Sciences Sackler colloquia website and published on CD-ROM. These Colloquia are made possible by a generous gift from Mrs. Jill Sackler, in memory of her husband, Arthur M. Sackler.

This book was released on 1997 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication contains the 20 invited papers which were presented and discussed at the Technical Consultation on Reduction of Wastage in Fisheries held in Tokyo, Japan (28 October - 1 November 1996). The first section consists of papers which discuss the issues of wastage reduction, selectivity of fishing practices, utilization of presently discarded catch and management measures that are being or have been made in various countries to reduce wastage and discards. The second section contains papers which review the bycatch and discards problem in various regions and endeavour to quantify and qualify the magnitude of wastage. Comparisons are made with earlier estimates given in FAO Fisheries Technical Paper no. 339 - A Global Assessment of Fisheries Bycatch and Discards.

Download or read book Aquaculture and Behavior written by Felicity Huntingford and published by John Wiley & Sons. This book was released on 2012-02-13 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern aquaculture is faced with a number of challenges, including public concern about environmental impacts and the welfare of farmed fish. A fundamental understanding of fish biology is central to finding ways to meet these challenges and is also essential for maintaining the industry's sustainability. Furthermore, the behaviour of fish under culture situations has long been ignored despite heavy commercial losses that can result from fish stressed and hence disease-prone, due to bad husbandry techniques. This important book summarises the current understanding of the behavioural biology of farmed species and illustrates how this can be applied to improve aquaculture practice. Informative and engaging, Aquaculture & Behavior brings the reader up-to-date with major issues pertaining to aquaculture. Everyone from fish farmers to upper level students will find this book a valuable and practical resource. Libraries in universities and research establishments where animal behavior, aquaculture, veterinary and biological sciences are studied and taught should have copies of this work on their shelves.
