PREPARATION OF THIS DOCUMENT

This document reports on the final results and conclusions of a workshop held in Rome, from 23 to 26 October 2006. The objectives of this workshop were to: i) recommend an approach to evaluate ecological indicators of changes in marine ecosystems in data-poor locations; and ii) report on findings for a stock assessment model proposed for data-poor situations where only catch data is available. The group of experts convened for this purpose consisted of Gabriella Bianchi, William Cheung, Kevern Cochrane, Beth Fulton, Paul Medley, Carolina Minte-Vera and Marcelo Vasconcellos.

The Government of Japan is gratefully acknowledged for providing financial support for the workshop and preparation of the present document through the Trust Fund Project GCP/INT/920/JPN on "Capacity building for an ecosystem approach: including interactions with marine mammals".

ABSTRACT

This publication major objectives are to recommend an approach to evaluate the performance of ecological indicators applicable to the monitoring of the ecosystem impacts of fisheries in data-poor areas, and to evaluate the results of a stock assessment method (biomass-fleet dynamics model) previously proposed for fisheries in situations where only catch data is available.
