Book (series)Technical studyProduction of high-value products from the by-products of aquatic food processing 2024
Also available in:
No results found.The processing of aquatic food generates substantial by-products, including animal heads, skins, bones, scales, visceral organs and shells, etc., which can constitute between 30 percent and 70 percent of the whole body of aquatic organisms. These by-products retain numerous bioactive molecules suitable for extraction and application in the nutraceutical, functional food, pharmaceutical, biomedical, cosmetic and material industries, and have the potential to yield high-value products. The transition from aquatic food waste to high-value products presents multiple benefits, including: (i) enhanced human nutrition and health through nutrient and bioactive component provision; (ii) mitigation of environmental pollution by reducing waste; and (iii) improved economic returns because aquatic food waste is transformed into high-value products rather than low-value animal feeds or fertilizers. This guide presents strategic and technical insights by outlining key principles for producing high-value items, including collagen, gelatine, bioactive peptides, chitin, chitosan, chondroitin sulphate, fish leather and fish oil, from the by-products of aquatic food processing. -
No Thumbnail AvailableProjectProgramme / project reportAquaculture development and coordination programme. Fish feed technology. Lectures presented at the FAO/UNDP Training Course in Fish Feed Technology, Seattle, Washington, 9 October - 15 December 1978 1980
Also available in:
No results found.The need for developing suitable feeds based on locally available inexpensive ingredients has been widely recognized. Since lack of trained personnel is the main constraint in the development of fish feed technology in developing countries, the FAO/UNDP Aquaculture Development and Coordination Programme (ADCP) organized a special training course in fish feed technology at the College of Fisheries, University of Washington, Seattle, with a view to forming a small corps of fish feed specialists wh o could then be the focal points for future feed development programmes in their respective countries. The first report of the training course was presented in the report ADCP /REP/79/8. This present volume represents the edited texts of lectures presented by different specialists. Some additional material has been included for more complete coverage of the subject. Together, these texts may be considered to constitute a manual on fish feed technology, even though they were not prepared for that purpose. Twenty-six papers are included, under the general headings: (1) Digestion, physiology and anatomy; (2) nutritional bioenergetics; (3) nutritional biochemistry; (4) feedstuffs; (5) feed formulation; (6) feed manufacturing technology; (7) practical diets; and (8) quality control. Appendices include conversion tables, electrical data, and details on pelletability of selective feedstuffs, pellet die specifications, and equipment requirements for an 8 ton an hour feed mill. -
ProjectTechnical reportTechnical reports - product by product development from Nile Perch (summary table) 1988
Also available in:
No results found.Since dairy meal is becoming increasingly expensive in Kenya and threatens the fish rearing industry, a systematic study was initiated on the possibility of using aquatic plants and Nile perch silage. The water plants, Azolla niloticus, Lemna perpusilla and Pistia striatotis were tested as a fishmeal for Tilapia zillii and riverine fishes. Low growth rates were achieved in the tilapias. The value of the Azolla protein in fish diet is discussed in relation to dietary requirement in cultured fish. This study demonstrates that the water plant Azolla niloticus together with Nile perch silage as a supplement can be used as a complete diet for cultured fish. It is hoped that the project will help provide detailed information on the nutritional value of the water plant Azolla niloticus and its long-term susceptibility to various inclusions as a complete feed, and conduct least cost feed formulations to make recommendations as to the maximum inclusion levels.

Book (series)FlagshipThe State of the World’s Forests 2020
Forests, biodiversity and people
2020As the United Nations Decade on Biodiversity 2011–2020 comes to a close and countries prepare to adopt a post-2020 global biodiversity framework, this edition of The State of the World’s Forests (SOFO) examines the contributions of forests, and of the people who use and manage them, to the conservation and sustainable use of biodiversity. Forests cover just over 30 percent of the global land area, yet they provide habitat for the vast majority of the terrestrial plant and animal species known to science. Unfortunately, forests and the biodiversity they contain continue to be under threat from actions to convert the land to agriculture or unsustainable levels of exploitation, much of it illegal.The State of the World’s Forests 2020 assesses progress to date in meeting global targets and goals related to forest biodiversity and examines the effectiveness of policies, actions and approaches, in terms of both conservation and sustainable development outcomes. A series of case studies provide examples of innovative practices that combine conservation and sustainable use of forest biodiversity to create balanced solutions for both people and the planet. -
BookletCorporate general interestEmissions due to agriculture
Global, regional and country trends 2000–2018
2021Also available in:
No results found.The FAOSTAT emissions database is composed of several data domains covering the categories of the IPCC Agriculture, Forestry and Other Land Use (AFOLU) sector of the national GHG inventory. Energy use in agriculture is additionally included as relevant to emissions from agriculture as an economic production sector under the ISIC A statistical classification, though recognizing that, in terms of IPCC, they are instead part of the Energy sector of the national GHG inventory. FAO emissions estimates are available over the period 1961–2018 for agriculture production processes from crop and livestock activities. Land use emissions and removals are generally available only for the period 1990–2019. This analytical brief focuses on overall trends over the period 2000–2018. -
BookletHigh-profileFAO Strategy on Climate Change 2022–2031 2022The FAO Strategy on Climate Change 2022–2031 was endorsed by FAO Council in June 2022. This new strategy replaces the previous strategy from 2017 to better FAO's climate action with the Strategic Framework 2022-2031, and other FAO strategies that have been developed since then. The Strategy was elaborated following an inclusive process of consultation with FAO Members, FAO staff from headquarters and decentralized offices, as well as external partners. It articulates FAO's vision for agrifood systems by 2050, around three main pillars of action: at global and regional level, at country level, and at local level. The Strategy also encourages key guiding principles for action, such as science and innovation, inclusiveness, partnerships, and access to finance.
