    The second meeting of the FAO/CECAF Working Group on the Assessment of Small Pelagic Fish – Subgroup South met in Accra, Ghana, from 19 to 28 October 2009. The overall objective of the Working Group is to contribute to the improved management of small pelagic resources in West Africa through the assessment of the state of the stocks and fisheries to ensure sustainable use of these resources for the benefit of coastal countries. The Working Group focused on data quality and on the analysis of tre nds in the basic data (catch, effort, abundance indices and length distribution) and trends in the fishery independent survey data. The species assessed by the Working Group were: sardinella (Sardinella aurita and Sardinella maderensis), bonga (Ethmalosa fimbriata), anchovy (Engraulis encrasicolus) and horse mackerel (Trachurus trecae and Decapterus rhonchus) and other Carangidae, in the region between the northern border of Guinea-Bissau and the southern border of Angola.

    The second meeting of the FAO/CECAF Working Group on the Assessment of Demersal Resources, Sub-Group South met in Freetown, Sierra Leone, from 9-18 October 2008. The Group assessed the status of the demersal resources in Southwest Africa and advise on future effort and catch levels. The advices for the stocks are given in relation to the agreed reference points F0.1, FMSY, B0.1. There was uncertainty in the assessments carried out, mostly due to deficiencies in some of the data available. Catch and effort data were incomplete for the latter years in several of the data series. The working group also noted that catch and effort information from some countries in the region is no longer being collected. Overall, the quantity and quality of the data available to the working group has worsened since the last meeting. This is of serious concern as these basic data are required for the assessment of the stocks and the situation must be corrected in the future if the group is to be able to c ontinue to provide useful fisheries management advice. The results of the assessments show that many of the stocks analyzed are fully to overexploited, and the working group thus recommended that fishing effort should be reduced for the overexploited stocks or not increased for the other stocks, to avoid further depletion. When possible, recommendations on catch levels are also indicated for each stock. Given that most fisheries in the region are multi specific, an overall reduction in fishing e ffort is necessary.

    The fourth meeting of the FAO/CECAF Working Group on the Assessment of Demersal Resources, Subgroup South met in Libreville, Gabon, from 6-15 September 2017. The overall objective of the Group is to contribute to the improvement of the management of demersal resources in Southwest Africa through assessment of the state of the stocks and the fisheries to ensure the best sustainable use of the resources for the benefit of the coastal countries. A total of around 53 stocks were analyzed and when possible assessed by the group. For each of these sections, information is provided on the fisheries, sampling scheme and intensity, biological characteristics, stock identity, trends (catch, effort, biological data and abundance indices), assessment, management recommendations and future research. As for the previous meeting of the Working Group in 2011, trends and quality of the basic data (catch, effort and length frequencies) collected by each country, were one the main topics of discussion during the 2017 Working Group meeting. The results of the assessments show that some of the stocks analyzed are fully to overexploited, and the working group thus recommended that fishing effort should be reduced for the overexploited stocks or not increased for the other stocks, to avoid further decreas. For most of the stocks assessed, the only series of stock abundance indices available were commercial CPUE data series. When possible, recommendations on catch levels are also indicated for each stock. Given that most demersal fisheries in the region are multi specific, an overall reduction in fishing effort is necessary. A summary of the assessments and management recommendations is given in Table 8. La quatrième réunion du Groupe de travail FAO/COPACE sur l'évaluation des ressources démersales, sous-groupe Sud s’est tenu à Libreville, Gabon, du 6 au 15 septembre 2017. L'objectif global du Groupe de travail est d’évaluer l’état des ressources démersales dans la zone COPACE Sud et de faire des recommandations sur les options d’aménagement et d’exploitation des pêcheries pour assurer une utilisation optimale et durable de ces ressources au profit des pays côtiers. Au total, environ 53 stocks ont été analysés, et, lorsque cela a été possible, ils ont été évalués par le groupe de travail. Pour chacun de ces groupes, des informations sont fournies sur les pêcheries, les schémas et l’intensité d’échantillonnage, les caractéristiques biologiques, l’identité du stock, les tendances des données (capture, effort, données biologiques et indices d’abondance), les évaluations, les recommandations d’aménagement et recherches futures. Comme dans la réunion précédente du Groupe de travail qui s’est tenue en 2011, parmi les principaux thèmes de discussion de la réunion de 2017, on peut citer les questions relatives à la qualité et aux tendances des données de base collectées par chaque pays (captures, effort et distribution de taille). Les résultats des évaluations montrent que de nombreux stocks analysés sont pleinement exploités ou surexploités. Le Groupe de travail a donc recommandé que l’effort de pêche soit réduit pour les stocks surexploités et n’augmente pas pour les autres afin d’éviter leur épuisement dans le futur. Pour la plupart des stocks évalués, les seuls indices disponibles de l’abondance du stock étaient les données de CPUE commerciales. Lorsque cela a été possible, des recommandations sur le niveau des captures sont aussi indiquées pour chaque stock. Étant donné que la plupart des pêcheries de la région sont multispécifiques, une réduction générale de l’effort de pêche est nécessaire. Le résumé des évaluations et des recommandations d’aménagement est fourni dans le tableau 8.
