Synopsis (short abstract) 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.

    Aquaculture development. 5. Use of wild fish as feed in aquaculture 2011
    Also available in:
    These 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.

    Report of the FAO Expert Workshop on On-farm feeding and feed management in aquaculture. Manila, the Philippines, 13–15 September 2010. 2010

    The FAO Expert Workshop on “On-farm feeding and feed management in aquaculture” was convened in Manila, the Philippines, from 13–15 September 2010. The workshop was attended by a wide range of aquaculture researchers, development specialists and industrial experts from around the world. The workshop was convened by the FAO Fisheries and Aquaculture Department, Aquaculture Service (FIRA) and was hosted by the Southeast Asian Fisheries Development Center Aquaculture Department (SEAFDEC/AQD) based in Iloilo, the Philippines. The workshop was organized with three objectives: a) to review and analyze the existing knowledge on the application of feed management as a tool for reducing feed costs in aquaculture, b) to identify the major issues and constraints of feed management and those that need to be addressed and c) to prepare a list of recommendations to define/suggest the future course of action, including the preparation of technical manuals/guidelines for dissemination to farmers. The workshop convened both in plenary and in working groups. In the plenary, participants heard technical presentations intended to orient them to the issues and constraints pertaining to on-farm feeding and feed management. These presentations included invited reviews, case studies and synthesis of the case studies. Following several working group deliberations and a general plenary discussion, the participants identified seven primary issues that currently constrain feed use and management in aqua culture, namely: 1) limited access to information on feed and feed ingredients (availability, prices and quality); 2) poor feed preparation, processing, handling and storage at the farm level; 3) inadequate monitoring of feed and farm performances; 4) low impact of current dissemination strategies on improved feeding and feed management; 5) gaps in the understanding of the economic aspects of feed management; 6) health aspects and their implications on feed management; and 7) feed quality – lack of regulatory mechanisms. A comprehensive set of recommendations was developed to overcome the constraints that were identified, and it is anticipated that these recommendations will guide FIRA’s future work in this arena. The workshop proceedings and recommendations, invited reviews, case studies and syntheses will form the basis for an FAO Fisheries and Aquaculture Technical Paper entitled “On-farm feeding and feed management in aquaculture” which will be published in due course.

    Feed ingredients and fertilizers for aquatic animals: sources and composition 2009
    Also available in:
    No results found.
    The present technical paper presents an up-to-date overview of the major feed ingredient sources and feed additives commonly used within industrially compounded aquafeeds, including feed ingredient sources commonly used within farm-made aquafeeds, and major fertilizers and manures used in aquaculture for live food production. Information is provided concerning the proximate and essential amino acid composition of common feed ingredient sources, as well as recommended quality criteria and relativ e nutritional merits and limitations, together with a bibliography of published feeding studies for major feed ingredient sources by cultured species. The main body of the document deals with the nutritional composition and usage of major feed ingredient sources in compound aquafeeds, as well as the use of fertilizers and manures in aquaculture operations. Major feed ingredient and fertilizer groupings discussed include: animal protein sources, plant protein sources, single cell protein sources, lipid sources, other plant ingredients, feed additives, and fertilizers and manures. The concluding section of the document undertakes a comparative analysis of the essential amino acid profiles of the major reported feed ingredient sources for cultured finfish and crustaceans, and presents average reported dietary inclusion levels of major feed ingredient sources used within practical feeds, including their major attributes and limitations. Finally, the importance of feed safety, traceability, and use of good feed manufacturing practices is stressed, together with the importance of considering the long term sustainability of feed ingredient supplies.
