    A permanent FAO/CECAF Working Group composed of scientists from the coastal countries and from those countries or organizations playing an active role in demersal fisheries in Northwest Africa, was created by CECAF in 2000. The first meeting of Subgroup North was organized in Saly, Senegal, from 14 to 23 September 2004. The overall objective of the Group is to contribute to the improvement of the management of demersal resources in Northwest Africa through assessment of the state of stocks and fisheries to ensure the best sustainable use of the resources for the benefit of coastal countries. The study zone for the Working Group is the CECAF zone of the Central-East Atlantic Ocean between Cap Spartel and the south of Senegal. For reasons of heterogeneity, the species and stocks assessed by the Working Group were divided into four groups: hake, other demersal fish, shrimps and cephalopods. Un Groupe de travail permanent FAO/COPACE, composé de scientifiques des États côtiers et des pays ou organisations qui jouent un rôle actif dans les pêcheries démersales de l’Afrique nord-ouest a été créé par le COPACE en 2000. La première réunion du Sous-groupe Nord a été organisée à Saly, Sénégal, du 14 au 23 septembre 2004. L’objectif général du Groupe de travail est de contribuer à améliorer l’aménagement des ressources démersales en Afrique du Nord-Ouest par l’évaluation de l’état des stocks et des pêcheries afin d’assurer une meilleure utilisation de ces ressources pour le bénéfice des pays côtiers. La zone d’étude du Groupe de travail est la zone COPACE de l’océan Atlantique Centre-Est, entre Cap Spartel et le sud du Sénégal. En raison de l’hétérogénéité des espèces et des stocks, le Groupe de travail sur les démersaux a été divisé en quatre groupes: merlus, autres démersaux, crevettes et céphalopodes.

    A permanent FAO/CECAF Working Group composed of scientists from the coastal countries and from those countries or organizations playing an active role in demersal fisheries in Central-West Africa, was created by CECAF in 2000.

The overall objective of the Group is to contribute to the improvement of the management of demersal resources in Northwest Africa through assessment of the state of stocks and fisheries to ensure the best sustainable use of the resources for the benefit of coastal countries. The study zone for the Working Group is the CECAF zone of the Central-East Atlantic Ocean between Cap Spartel and the south of Senegal. For reasons of heterogeneity, the species and stocks of the demersal Working Group were divided into four groups: hake, other demersals, shrimps and cephalopods. For each of these groups information is provided on the fisheries: sampling sche mes and sampling intensity, biological characteristics, stock identity, trends (catch, effort, biological data and abundance indices), assessment, management recommendations and future research. Approximately 22 different stocks-units were analysed and the results discussed. The quality and trends in basic data (catch, effort, length distribution) collected by each different country and the sampling system, represented some of the main discussion topics of the second meeting 2004 of this Working Group. The Working Group decided that the majority of the demersal stocks were fully exploited and that, for some of them, the fishing effort should be heavily reduced. A summary of the assessments and management measures is given at the end of this report.

    A permanent FAO/CECAF Working Group composed of scientists from the coastal countries and from those countries or organizations playing an active role in demersal fisheries in Central-West Africa, was created by CECAF in 2000. The first meeting of Subgroup North was organized in Saly, Senegal, from 14 to 23 September 2004. The overall objective of the Group is to contribute to the improvement of the management of demersal resources in Northwest Africa through assessment of the state of stocks an d fisheries to ensure the best sustainable use of the resources for the benefit of coastal countries. The study zone for the Working Group is the CECAF zone of the Central-East Atlantic Ocean between Cap Spartel and the south of Senegal. For reasons of heterogeneity, the species and stocks assessed by the Working Group were divided into four groups: hake, other demersal fish, shrimps and cephalopods. For each of these groups information is provided on the fisheries: sampling schemes and sampling intensity, biological characteristics, stock identity, trends (catch, effort, biological data and abundance indices), assessment, management recommendations and future research. Approximately 26 different stocks-units were analysed and the results discussed. The models provided reliable results for 18 of them, of which 14 are overexploited and 4 seem not to be fully exploited. For eight stocks, the results obtained by the models from the available data were not conclusive. Although the model di d not give reliable results for these stocks, other information from fisheries and surveys indicate that many of them are overexploited. The results of the assessments confirm the conclusion reached at the last 2007 meeting that most of the stocks assessed are overexploited. A summary of the assessments and management measures is given at the end of this report.
