A total of 1,354 introductions of 237 species into 140 countries are analyses. The number of introductions carried out rose from the middle of the last century until the 1960s and have lessened since then.

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.

Both Penaeus vannamei and P. stylirostris are introduced species in Asia and the Pacific. They have now become important commercial shrimp species in many countries in Asia. The main reason behind the importation of P. vannamei to Asia has been the perceived poor performance, slow growth rate and disease susceptibility of the major indigenous cultured shrimp species, P. chinensis in China and P. monodon virtually everywhere else. However, for many reasons, particularly with the evidence of the introduction of exotic viruses to the region, there has been caution on the part of many Asian governments for the introduction of P. vannamei and P. stylirostris. Nevertheless, this caution has not been demonstrated by the private sector, which has been bringing stocks of illegal and often disease carrying P. vannamei into Asia from many locations, as well as moving infected stocks within Asia. The commercial success of these introductions, despite disease problems, has allowed the development of substantial culture industries for these alien penaeids within Asia, particularly in China and Thailand. One effect of this is that it is rapidly becoming difficult to control the importation and development of this new industry. This report attempts to gather all of the currently available data on the extent of P. vannamei and P. stylirostris importation and culture in Asia, its potential problems and benefits, and in this way to serve as a source document from which to investigate further means by which control over this issue might be re-established. Recommendations aimed at controlling the importation, testing and culture of these species have been made for all levels and are included in this report.--Publisher's description.

Marine Bivalve Molluscs Marine Bivalve Molluscs is a comprehensive and thoroughly updated Second Edition of Bivalve Molluscs, covering all major aspects of this important class of invertebrates. As well as being an important class biologically and ecologically, many of the bivalves are fished and cultured commercially (e.g. mussels, oysters, scallops and clams) in a multi-billion dollar worldwide industry. Elizabeth Gosling has written a landmark book that will stand for many years as the standard work on the subject. Chapters in Marine Bivalve Molluscs cover morphology, ecology, feeding, reproduction, settlement and recruitment, growth, physiology, fisheries, aquaculture, genetics, diseases and parasites, and public health issues. A full understanding of many of these aspects is vital for all those working in bivalve fisheries and culture. An essential purchase for anyone concerned with this important class of animals, copies of Marine Bivalve Molluscs should be on the shelves of biologists, ecologists, environmental scientists, fisheries scientists and personnel within the aquaculture industry. Copies of the book should be available in all libraries and research establishments where these subjects are studied or taught. REVIEWS OF THE FIRST EDITION An admirable achievement...a valuable addition to marine sciences libraries everywhere. The back cover of this book says that it is a landmark text that will stand for many years as the standard work on this subject. I can only agree with this sentiment. ~ Aquaculture A welcome addition to the literature and provides the reader with a comprehensive overview of biological and environmental factors that affect and control both natural populations of marine bivalves and culture operations. ~ Aquaculture International The author has done an admirable job in compiling a wealth of information into a readable text. ~ Transactions of the American Fisheries Society Will serve well as a description of much of both the experimental biology and the aquaculture of bivalves. ~ Journal of Experimental Marine Biology and Ecology Provides excellent reviews of all major aspects...an extremely important reference for anyone engaged in bivalve research, fisheries management, and aquaculture. ~ Quarterly Review of Biology The book is very readable, in an easy style. It is well illustrated and there is a wealth of data and statistics presented. ~ Bulletin of the Malacological Society of London

This publication provides background material and detailed technical procedures to assist countries and territories in Asia in implementing the Asia regional technical guidelines on health management for the responsible movement of live aquatic animals. The technical guidelines and their associated implementation plan, the Beijing consensus and implementation strategy (BCIS) (See FAO Fisheries Technical Paper no. 402), provide expert guidance for national and regional efforts to reduce the risks of disease due to transboundary movement of live aquatic animals.

En rekke planter og dyrearter som ikke naturlig hører hjemme her, blir i dag innført til Norden, noe som i mange tilfeller kan føre til utilsiktede økologiske effekter, for ikke å si direkte skade. Denne rapporten identifiserer de 1382 artene som har kommet til Norden, enten det er med overlegg eller ikke. Boken gir også oversikt over relevante internasjonale lover og retningslinjer i dette spørsmålet. Engelsk tekst.
