    Global trends in status and management of assessed stocks: achieving sustainable fisheries through effective management 2020

    This report provides an overview of the biological status of assessed stocks around the world and relates measures of stock status to the strength of fisheries management. Stock assessment outputs, consisting primarily of time series of abundance and fishing pressure relative to target reference points, were compiled for 548 marine fish and invertebrate stocks in the RAM Legacy Stock Assessment Database. Data summary methods included: global and regional mean trends of abundance and fishing pressure relative to target reference points; bivariate plots of relative abundance and fishing pressure; estimates of potential equilibrium yield foregone at current fishing pressure; and proportions of stocks in different biomass status categories. These measures of stock status were summarized at the global level as well as separated by 16 FAO Major Fishing Areas and ocean basin regions for comparison.

    This document contains the report of the FAO/RECOFI Regional Workshop on Fishery Stock Indicators and Stock Status that was held in Tehran, Islamic Republic of Iran, from 26 to 29 July 2009. At the fourth session (2007) of RECOFI held in Jeddah, Kingdom of Saudi Arabia, the Secretariat prepared for the minimum requirements of stock assessment. The Commission recognized that those requirements were too complicated and noted a shortage of expertise. The effort was resumed at the second m eeting of the Working Group on Fisheries Management (WGFM) in 2008 where a shift to a pragmatic approach based on an Ecosystem Approach to Fisheries management (EAF) with adaptive procedures was recommended. The objective of the Workshop was to review the availability of data on the biology of the identified priority resources, catch and effort statistics for the relevant fisheries, other socio-economic statistics, results of stock assessments and other relevant research activities i n member countries; to identify the major gaps in knowledge and information, priority areas for regional cooperation and potential joint activities; and to formulate the RECOFI work program for regional cooperation in assessment of stocks and fishery status appraisal in the short and medium term. Employing a simple matrix of Susceptibility Productivity Analysis (PSA), the participants identified three areas of particular concern. These are the ecosystem-wide impact of shrimp trawls, th e exploitation of neritic demersal assemblages as well as sharks as indicators of the overall level impact of exploitation, and, thirdly, the stock status of a selected priority species, Scomberomorus commerson, for which historic data are available. The Workshop concluded with a set of recommendations to the WGFM that focused on improvement of data collection and monitoring capacity and members¿ contributions to scientific knowledge through joint activities.
