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 in order to ensure sustainable use of these resources for the benefit of coastal countries. 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. La quatrième réunion du Groupe de travail FAO/COPACE sur l’évaluation des petits pélagiques – Sous-groupe Sud, s’ets tenue à Elmina, Ghana, du 12 au 20 septembre 2018. L’objectif général du Groupe de travail est d’améliorer la gestion des ressources en petits pélagiques en Afrique de l’Ouest grâce à l’évaluation de l’état des stocks et des pêcheries de façon à assurer une utilisation durable de ces ressources au bénéfice des pays côtiers. Les espèces évaluées par le Groupe de travail sont les suivantes: les sardinelles (Sardinella aurita et t Sardinella maderensis), l’ethmalose (Ethmalosa fimbriata), l’anchois (Engraulis encrasicolus) et les chinchards (Trachurus trecae et Decapterus rhonchus) et autres carangidés, dans la région située entre la frontière nord de la Guinée-Bissau et la frontière sud de l’Angola. -

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 in 2014 to ensure sustainable use of these resources for the benefit of coastal countries, and give management advice to the fisheries adminis tration. The Working Group focused on data quality and on the analysis of trends in the basic data (catch, effort, abundance indices and length distribution) and trends in the fishery independent survey data. This reports contains an analysis of the trends in fisheries and fisheries independendent data and provides an update on the state of the pelagic stocks in the Southern CECAF region. The advice for the stocks is given in relation to the agreed biological reference points F0.1, FMSY, B0.1. Although important changes were observed in the abundance and exploitation level for some of the stocks, the overall general situation with respect to the state of the different stocks was found to be similar to that of 2009. -

No results found.The third meeting of the FAO/CECAF Working Group on the Assessment of Demersal Resources, Subgroup South met in Accra, Ghana, from 15-24 November 2011 in the FAO Regional Office.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. Six stocks could not be assessed using any of the models because the data available to the working gr oup were not in the appropriate format and/or not sufficient to use in the assessment models. 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. The results of the assessments show that many of the stocks analyzed are fully (13) to overexploited (9), and the working group thus recommended that fishing effort should be reduced for t he 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 effort is necessary.
