Book (series)Aquaculture development. 5. Use of wild fish as feed in aquaculture 2011These technical guidelines on the use of wild fish as feed in aquaculture have been developed to support sections of the FAO Code of Conduct for Responsible Fisheries (CCRF) addressing responsible fisheries management (Article 7) and aquaculture development (Article 9) and in particular in support of Articles 9.1.3 , 9.1.4 and 9.4.3. The objective of these guidelines is to assist those concerned to ensure both aquaculture growth and equitable and sustained use of available fish stocks. The guide lines cover a number of issues relevant to the use of wild fish in feeds in aquaculture, ranging from ecosystem and environmental impacts, ethical issues and responsible use of fish as feed, aquaculture technology and development, and statistics and information needs for management. However, issues relating fisheries management are not covered here, as these have been considered within separate sets of guidelines related to fisheries management and there exist several sets of technical guideline s on the sustainable management of fisheries and several continuing initiatives to improve sustainable management of fisheries which inter alia would also apply to feed-fish fisheries.

Book (series)Aquaculture in desert and arid lands: development constraints and opportunities. FAO Technical Workshop. 6-9 July 2010, Hermosillo, Mexico 2011
Also available in:
No results found.Aquaculture in desert and arid lands has been growing steadily over the last decade thanks to the modern technologies and alternative energy sources that have allowed water in these places of extremes to be exploited more effectively and more efficiently, using it for both crop irrigation and production of fish. This publication presents the evolution of desert and arid lands aquaculture in the past few decades in seven countries and regions (Australia, Egypt, Israel, Mexico, Southern Africa, the United States of America and Central Asia) describing the achievements of a number of farming operations, which demonstrate the significant potential for farming commercial aquatic organisms using geothermal, fresh and brackish waters. The global overview on desert aquaculture development shows, through the use of maps and tables, those countries with vast extensions of arid territories that should be better investigated for potential aquaculture development. Limiting f actors were extensively discussed during the workshop, and several measures were identified and proposed. Desert conditions are characterized by high day temperatures, cold winter nights, high solar radiation, scarce precipitation and very low relative humidity. The experts reached consensus on the definition of aquaculture in the desert and arid lands, which was defined as follows: “Aquaculture activities practised in desert and arid lands characterized by low precipitation (<250 mm/y ear), high solar radiation, high rate of evaporation, using subsurface and surface water”. At the end of the workshop, a series of recommendations were elaborated by the experts to assist FAO Member countries wishing to generate a favourable national environment to promote sustainable aquaculture development. Limited water supply remains the single largest constraint for aquaculture development in arid and semi-arid regions; however, where the resource is available, the development of integrated aqua-agriculture systems may certainly provide economic output opportunities from such resource-limited regions. Such farming systems may also enable the production of highly priced fish, vegetables and fruits all year round. -
Book (series)Capture-based aquaculture. Global overview. 2008
Also available in:
Aquaculture is a diverse and multibillion dollar economic sector that uses various strategies for fish production. The harvesting of wild individuals from very early stages in the life cycle to large mature adults for on-growing under confined and controlled conditions is one of these strategies. This system, referred to as capture-based aquaculture, is practised throughout the world using a variety of marine and freshwater species with important environmental, social and economic implications. The need to evaluate the sustainability of this farming practice in light of its economic viability, the wise use of natural resources and socio-environmental impacts as a whole has been extensively discussed at national, regional and international levels. In 2004, the Food and Agriculture Organization of the United Nations (FAO) launched a project entitled “Towards sustainable aquaculture – selected issues and guidelines” funded by the Government of Japan which included a thematic component o n the use of wild fish and fishery resources for aquaculture production. The objective is to produce a set of technical guidelines that would assist policy-makers in developing informed and appropriate capture-based aquaculture regulations that would take into account the use and conservation of the aquatic resources exploited. This publication contains technical information prepared in support of and background material for the “FAO international workshop on technical guidelines for the respo nsible use of wild fish and fishery resources for capture-based aquaculture production” held in Viet Nam in October 2007. The first draft of the technical guidelines on capture-based aquaculture was produced during this meeting. This publication contains two parts. Part 1 consists of two reviews on (a) environmental and biodiversity and (b) social and economic impacts of capture-based aquaculture and Part 2 consists of eleven species review papers. Both marine and freshwater examples have been r eviewed and include finfish (mullet, bluefin tuna, European eel, cod, grouper, yellowtail, Clarias catfish, Indian major carps, and snakehead and Pangasiid catfish), crustaceans (mud crab) and molluscs (oyster).
