Descripción
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.
