Book (stand-alone)Technical bookNon-wood forest products In 15 countries of Tropical Asia
An overview
2002Also available in:
No results found.This regional study presents an overview of the socio-economic importance of the use of non-wood forest products (NWFP) in 15 countries of Tropical Asia. The document consists of two main parts: (1) presentation of background information on the programme activities and methodology and an analysis of the available information at the regional level; and (2) presentation of data on NWFP at the national level (so-called "country profiles"). -

Book (series)Technical studyManual on the Production and Use of Live Food for Aquaculture 1996
Also available in:
No results found.The cultivation of fish and shellfish larvae under controlled hatchery conditions requires not only the development of specific culture techniques, but in most cases also the production and use of live food organisms as feed for the developing larvae. The present manual describes the major production techniques currently employed for the cultivation of the major types of live food commonly used in larviculture, as well as their application potential in terms of their nutritional and physical pro perties and feeding methods. The manual is divided into different sections according to the major groups of live food organisms used in aquaculture, namely micro-algae, rotifers, Artemia, natural zooplankton, and copepods, nematodes and trochophores. -
Book (series)Technical bookProbiotics in food
Health and nutritional properties and guidelines for evaluation - Report of a Joint FAO/WHO Expert Consultation on Evaluation of Health and Nutritional Properties of Probiotics in Food including Powder Milk with Live Lactic Acid Bacteria
2006Also available in:
This paper includes joint FAO and WHO work to evaluate the latest information and scientific evidence available on the functional and safety aspects of food probiotics, as well as the methodology to assess such aspects, by bringing together worldwide scientific experts in the field. It includes the reports of the expert consultation and of the working group. These reports provide scientific advice in relation to the safety assessment of probiotics, general guidance for their evaluation and on specific questions in relation to their pathogenicity, toxigenicity, allergenicity, as well as to their functional and nutritional properties. The guidelines for the evaluation of probiotics in foods were developed as part of this joint effort, providing criteria and methodology to assess the efficacy and the safety of these products. -
Book (series)Technical studySmall-scale aquaponic food production – Integrated fish and plant farming 2014This technical paper begins by introducing the concept of aquaponics, including a brief history of its development and its place within the larger category of soil-less culture and modern agriculture. It discusses the main theoretical concepts of aquaponics, including the nitrogen cycle and the nitrification process, the role of bacteria, and the concept of balancing an aquaponic unit. It then moves on to cover important considerations of water quality parameters, water testing, and water sourci ng for aquaponics, as well as methods and theories of unit design, including the three main methods of aquaponic systems: media beds, nutrient film technique, and deep water culture. The publication discusses in detail the three groups of living organisms (bacteria, plants and fish) that make up the aquaponic ecosystem. It also presents management strategies and troubleshooting practices, as well as related topics, specifically highlighting local and sustainable sources of aquaponic inputs. The publication also includes nine appendixes that present other key topics: ideal conditions for common plants grown in aquaponics; chemical and biological controls of common pests and diseases including a compatible planting guide; common fish diseases and related symptoms, causes and remedies; tools to calculate the ammonia produced and biofiltration media required for a certain fish stocking density and amount of fish feed added; production of homemade fish feed; guidelines and considerations fo r establishing aquaponic units; a cost–benefit analysis of a small-scale, media bed aquaponic unit; a comprehensive guide to building small-scale versions of each of the three aquaponic methods; and a brief summary of this publication designed as a supplemental handout for outreach, extension and education.
