Book (series)Implementation of the International Plan of Action to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing
1. Methodologies and indicators for the estimation of the magnitude and impact of illegal, unreported and unregulated fishing: 1.2 A practical guide to delivering an estimate
2023Also available in:
No results found.Applying the principles and approaches from Volume 1 of this series, this practical guide details the steps necessary to plan, execute and present estimates of illegal, unreported and unregulated fishing. For the initial planning phase, the guide provides information on how to work with stakeholders to define objectives, examine and catalogue available data, and then match the objectives with the available data to determine the most useful estimation methods. Also discussed are subsequent steps involving designing a conceptual model, triangulating alternative approaches, dealing with data gaps and biases, and accounting for uncertainty. For the execution phase, guidance is provided for developing and running models, including checking preliminary outputs with stakeholders and experts, before refining and finalizing results. Guidance for the final presentation phase focuses on how to ensure the methodology, data inputs and gaps, and assumptions are clearly explained. As in the first two phases, allowing for feedback from stakeholders on the study results, and refining the outputs as necessary, will strengthen both the quality of the work and its uptake by decision-makers. -
Book (series)Implementation of the International Plan of Action to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing
1. Methodologies and indicators for the estimation of the magnitude and impact of illegal, unreported and unregulated fishing: 1.3 A catalogue of examples
2023Also available in:
No results found.This document complements previous technical guidance documents on planning and executing illegal, unreported and unregulated (IUU) fishing estimation studies by providing a catalogue of 26 estimation methodologies from published studies. These methodologies encompass a wide range of locations, fishing gear and IUU fishing types. The catalogue is organized around two ways of identifying relevant methodologies: a) the IUU fishing estimation approach; and b) the primary available data source. The five types of IUU fishing estimation approaches (“a”) include: 1) estimating total catch minus reported catch; 2) partitioning total catch into IUU/non-IUU fishing; 3) summing individual IUU fishing events to a total amount; 4) estimating “true” catches for suspect vessels or fleets; and 5) determining relative amounts or trends in IUU fishing. The four types of primary data sources (“b”) include: 1) fishery models; 2) commercial sources; 3) operational data; and 4) expert judgements, comparisons to catch compilations and stakeholder surveys. These two types of approaches help to identify the relevant methodologies presented as concise, individual one- to two-page summaries. Each methodology is described in terms of the key elements needed and how they can be sourced, the specific steps involved in constructing the estimate, and guidance on the applicability of the method. -
Book (series)Report of the FAO Regional Workshop on the Elaboration of National Plans of Action to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing - Southern and East Africa Subregion. Kariba, Zimbabwe, 24-28 November 2003. 2004

No results found.This document contains the report of, and the paper presented at, the FAO Regional Workshop on the Elaboration of National Plans of Action to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing – Southern and East Africa Subregion, held at Kariba, Zimbabwe, from 24 to 28 November 2003. The purpose of the Workshop was to assist countries in the southern and eastern Africa region to develop capacity so that they would be better placed to elaborate national plans of a ction to prevent, deter and eliminate illegal, unreported and unregulated fishing (NPOAs–IUU). The Workshop addressed the International Plan of Action to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing (IPOA–IUU) in detail and the Technical Guideline that had been developed to support the implementation of the IPOA–IUU; two case studies; decisionmaking about IUU fishing and skills development through identification of key issues relating to the NPOA–IUU, the vehicle through which the IPOA–IUU will be implemented by countries. Working groups were formed to encourage maximum participation. A review of regional fishery issues was discussed including ways of improving collaboration and identifying regional priorities. The document prepared by Ms J. Swan entitled “National plans to combat illegal, unreported and unregulated fishing: models for coastal and small-island developing states” was funded through FishCode Programme component projects G CP/INT/849/USA (“Support for the Implementation of the International Plan of Action to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing”) with Trust Fund support from the Government of the United States of America, and GCP/INT/823/JPN (“Responsible Fisheries for Small Island Developing States (SIDS)”) with Trust Fund support from the Government of Japan.
