The Handbook on small-scale freshwater fish farming provides a wealth of simply presented and illustrated information on freshwater fish farming in ponds, pens and cages, compiled form five booklets published on the subject in FAO s Better Farming Series between 1979 and 1990. Here is an improved format, particulars of pond, pen and cage location, construction and management are covered in outlines that can be modified to suit local conditions. The handbook is primarily intended to help workers, technicians and teachers present their knowledge of freshwater fish farming to small-scale farmers. For example, it can be used as a trainers aid in conjunction with the five original booklets, which can be distributed among trainees. The handbook ends with a set of questions that could be used to tests the trainees comprehension.

Aquaculture is developing, expanding and intensifying in almost all regions of the world, except in sub-Saharan Africa. Although the sector appears to be capable of meeting the gap between future demand and supply for aquatic food, there are many constraints and challenges which must be addressed in order to at least maintain the present level of per capita consumption at the global level. Key issues are the need for enhanced enforcement of regulation and better governance of the sector, as well as greater producer participation in the decision-making and regulation process. This publication examines past trends in aquaculture development as well as the current global status, drawing on a number of national and regional reviews.

In recent years the subject of pollution of natural waters by aquaculture has received considerable attention. With increasingly stringent regulation of wastewater quality from fish farms around the world, those involved in the industry need to be aware of the causes of pollution from fish and shellfish farms and of methods by which this pollution may be prevented. This book aims to bring the principles of wastewater treatment and other pollution control techniques for fish and shellfish farming to a wide audience of farmers, students, scientists and engineers; in fact anyone who works in aquaculture or pollution control. For this reason, the authors who have between them much experience in this area have written this important book with both the specialist and those new to the area in mind. As part of the growing Aquaculture Series, this title gives a comprehensive insight into this topic of vital importance to the aquaculture industry. This book should be on the shelves of all those involved in fish and shellfish farming and connected environmental issues, and available in universities and research establishments for students and professionals alike.

Agriculture and Industry in Brazil is a study of the economics of Brazilian agriculture and industry, with a special focus on the importance of innovation to productivity growth. Albert Fishlow and José Eustáquio Ribeiro Vieira Filho examine technological change in Brazil, highlighting the role of public policy in building institutions and creating an innovation-oriented environment. Fishlow and Vieira Filho tackle the theme of innovation from various angles. They contrast the relationship between state involvement and the private sector in key parts of the Brazilian economy and compare agricultural expansion with growth in the oil and aviation sectors. Fishlow and Vieira Filho argue that modern agriculture is a knowledge-intensive industry and its success in Brazil stems from public institution building. They demonstrate how research has played a key role in productivity growth, showing how prudent innovation policies can leverage knowledge not only within a particular company but also across whole sectors of the economy. The book discusses whether and how Brazil can serve as a model for other middle-income countries eager to achieve higher growth and a more egalitarian distribution of income. An important contribution to comparative, international, and development economics, Agriculture and Industry in Brazil shows how the public success in agriculture became a prototype for advance elsewhere.

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.

Expanded and updated, this second edition considers fish diseases in the context of the fish's environment, and includes coverage of many aspects of microbiology. The authors provide information on the structure of fish in order to help familiarize readers with general fish anatomy. All the bacterial taxa which have been reported as fish pathogens are included, and the material is subdivided for easy reference into sections which deal with characteristics of the diseases, isolation methods, characterization of the pathogens, diagnosis, epizootilogy, pathogenicity mechanisms and control. Written by bacteriologists for microbiologists, the book tabulates the identification procedures, and gives characteristics of pathogens, the diseases and their control. As farmed fish are of greater commercial importance, and the consequences of losses attributable to bacterial fish pathogens therefore of greater economic consequence, the authors concentrate on these rather than on wild stocks.
