No Thumbnail AvailableBook (series)Technical studyStatus of Interactions of Pacific Tuna Fisheries in 1995
Proceeding of the Second FAO Expert Consultation on Interactions of Pacific Tuna Fisheries Shimizu, Japan 23 to 31 January 1995
1996Also available in:
No results found.This publication includes forty papers and two abstracts of papers presented at the Second FAO Expert Consultation on Pacific Tuna Fisheries held in Shimizu, Japan, from 23 to 31 January 1995. The topics of the papers include: · reviews of tuna fisheries interactions and their research including methods for their study, · new methods for studying tuna fisheries interactions and examination of their applicability, · case studies on tuna fisheries interactions, · analyses of tuna fisheri es involved in interactions and their management, and · an overview of FAO’s project that co-organized and co-sponsored the Consultation. A supplement of an indexed bibliography of papers on tuna and billfish tagging, which was printed separately, is also included. The objectives of the Consultation were to: · review and integrate the outcome of the studies on tuna fisheries interactions, · summarize the extent of tuna fisheries interactions and unresolved research problems, and · fo rmulate guidelines for research on tuna fisheries interactions. The understanding of tuna fisheries interactions was enhanced significantly by recent studies. However, the Consultation noted that the number of quantified interactions is still small due primarily to difficulties associated with evaluating such interactions. The papers providing supporting information for the conclusions of the Consultation are presented in this publication. Interactions were found to vary in significance depend ing on the biological characteristics of the species involved, the sizes of fish caught, the local and stock-wide rates of exploitation, and the distance among fisheries. In many of the studies presented, the inadequacy of fisheries data was stressed. In addition, the lack of understanding of movements of the fish being studied was noted in several papers. General qualitative guidelines presented in several discussion papers stressed that specifically-designed studies be undertaken to adequately quantify interactions. Well-designed tagging experiments were thought to provide the most reliable information about interactions. Guidelines for the collection of data, biological and ecosystem research, modelling, and alternative methodologies for studying tuna fisheries interactions are also included. -
Book (series)Technical studyMultiple frame agricultural surveys. Volume 1. Current surveys based on area and list sampling methods 1996
Also available in:
No results found.Much of the required information for the agricultural sector, such as crop production, livestock inventories, and basic social and economic data, is obtained through periodic national, multi-purpose agricultural data collection programmes called "Current Agricultural Surveys". This manual describes the sample design, organization and implementation procedures for these current agricultural surveys using multiple frame probability sampling methods, which is a new methodology currently being adopted by many countries around the world. Specific case studies will be presented in Volume II. This handbook introduces the subject and describes the practical aspects of list and area frame construction and sample selection methods while recognizing the resource and specialized staff constraints faced by developing countries. -

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.

Book (series)GuidelineUnderstanding and implementing catch documentation schemes
A guide for national authorities
2022Catch documentation schemes (CDS) are just one in an array of tools designed to combat illegal, unreported and unregulated (IUU) fishing. The schemes provide a means for countries to cooperate in providing information about the legality of fish as it moves through the supply chain, from catch to market. Many countries are familiar with the specific information requirements on CDS forms; some, however, are less aware of the need for robust national systems to validate and verify that information. This document seeks to align and improve existing national monitoring, control and surveillance (MCS) tools, as well as product tracking systems, in order to support more effective national CDS implementation and strengthen CDS throughout the international supply chain. The document contains chapters on the legal and policy background to CDS, an introduction to the features and requirements of existing schemes, as well as guidance on how to handle CDS information requirements and identify national key data elements. Finally, it provides a series of exercises for assessing relevant national capabilities and coordination processes, including the management and exchange of information. -
Book (series)Technical reportData Collection Reference Framework
Version 1.0
2023Also available in:
No results found.The Western Central Atlantic Fishery Commission (WECACF) Data Collection Reference Framework (DCRF) is the first instrument to establish the foundation for comprehensive fisheries data and statistics collection and collation in the WECAFC area. The DCRF will feed the needs of developing, monitoring, assessing and reviewing regional fisheries policies such as fishery management plan as needed by any regional or subregional fishery body. -
ProjectFactsheetBuilding Resilience in Oman’s Small Pelagic Fisheries - UTF/OMA/025/OMA 2025
Also available in:
No results found.The project, launched in 2019 as a collaboration between FAO and the Government of Oman through the MAFWR, aimed to enhance the sustainability and economic viability of small pelagic fisheries, which contribute over 60 percent of Oman’s total fisheries production but face challenges such as overexploitation, outdated stock assessments and inefficient value chains.The project’s key objective was to develop a Development and Management Plan (DMP) based on the Ecosystem Approach to Fisheries (EAF), ensuring a balance between ecological sustainability and socioeconomic benefits. It focused on scientific stock assessment, improving downstream processing, and increasing economic returns through job creation and enhanced sector contributions to the Gross Domestic Product.
