Selective Breeding in Aquaculture: an Introduction
Author: Trygve GjedremPublisher: Springer Science & Business Media
ISBN: 9048127734
Category : Science
Languages : en
Pages : 221
Book Description
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.
Introduction of Non-indigenous Aquatic Species Implementation Plan
Author: Biological Invasions in Marine Ecosystems
Author: Gil RilovPublisher: Springer Science & Business Media
ISBN: 354079235X
Category : Science
Languages : en
Pages : 642
Book Description
Biological invasions are considered to be one of the greatest threats to the integrity of most ecosystems on earth. This volume explores the current state of marine bioinvasions, which have been growing at an exponential rate over recent decades. Focusing on the ecological aspects of biological invasions, it elucidates the different stages of an invasion process, starting with uptake and transport, through inoculation, establishment and finally integration into new ecosystems. Basic ecological concepts - all in the context of bioinvasions - are covered, such as propagule pressure, species interactions, phenotypic plasticity, and the importance of biodiversity. The authors approach bioinvasions as hazards to the integrity of natural communities, but also as a tool for better understanding fundamental ecological processes. Important aspects of managing marine bioinvasions are also discussed, as are many informative case studies from around the world.

ISBN: 9401793670
Category : Technology & Engineering
Languages : en
Pages : 317
Book Description
Ballast water management is a complex subject with many issues and still limited knowledge, however, it is building up on new scientific researches and practical experience. The Ballast Water Management Convention is the global legal framework which still needs to be implemented. This book brings together a long-term and newest experience from practical work, scientific research, administration and policy involvements, offering unique insights to readers who would like to learn more about this subject. It also provides recommendations and practical solutions especially important for professionals, administrations and organizations in the process of the implementation of this Ballast Water Management Convention.
An Evaluation of Small-scale Freshwater Rural Aquaculture Development for Poverty Reduction
Author: Publisher: Asian Development Bank
ISBN: 9715615503
Category : Aquaculture
Languages : en
Pages : 178
Book Description
This report looks at small-scale aquaculture from the viewpoint of poverty reduction. What are the main factors that enable fish farming to generate livelihoods and reduce poverty? Based on case studies, the first part of the report highlights the importance of access to capital assets--human, social, natural, physical, and financial--and to a range of transforming processes, such as markets, institutions, facilities, infrastructure, and services.
