No results found.The FAO Working Group on the Assessment of Small Pelagic Fish off Northwest Africa met in the Centre national de recherches océanographiques et des pêches (CNROP), Nouadhibou, Mauritania, from 24 to 31 March 2001. The working area was defined as the waters between the southern border of Senegal and the northern border of Morocco and the main groups of species defined as sardine, sardinellas, horse mackerels and mackerel. The overall objective of the Working Group is to contribute to the imp roved assessment of small pelagic resources in Northwest Africa and the analysis of fisheries management and exploitation options aimed at ensuring optimal and sustainable use of small pelagic fish resources for the benefit of coastal countries. The existing acoustic data series evidentiate that the main stocks have shown strong fluctuations during the last 9 years (particularly sardine and sardinella), but it is difficult to detect a long-term trend. On the other hand, CPUE data for horse mackerel and sardinella generally show a declining trend over the last few years. Although the group is not yet in a position to make detailed stock projections, it is expected that stocks will decline further in case of a further expansion of the (industrial) fishing effort in the area. As a general recommendation the group therefore suggests to adopt a precautionary approach, and not to increase the combined catch of small pelagic species above the average level attained during the most recent 5 years (1995-1999). -

No results found.The fifth meeting of the FAO Working Group on the Assessment of Small Pelagic Fish off Northwest Africa was held in Nouadhibou, Mauritania, from 26 April to 5 May 2005. The meeting continued to focus on data quality and on the analysis of trends in the basic data (landings, catch, effort, abundance, length and age distribution) and trends in the fishery independent survey data. The structure of the report is the same as that of the previous Working Group report (FAO, 2004), with the ad dition of two chapters, one on bonga (Ethmalosa fimbriata) and one on anchovy (Engraulis encrasicolus). The results of the assessments indicate that the sardine stock in Zone C is not fully exploited and the Working Group hence noted that the total catch level may be temporarily increased but should be adjusted to natural changes in the stock. A constant monitoring of the stock abundance and structure, by scientific surveys, independent from catch data, should be ensured, to detect u nanticipated changes that may require urgent management measures. As regards the central stock of sardine (Zones A+ B), it is recommended not to increase catches above the average level of the last five years. The stock of round sardinella was found to be fully exploited and it was hence recommended not to increase catches of sardinella above the current level (2004). As a precautionary approach, the Working Group recommended not to increase catches above the average level of the las t five years for the horse mackerels and not to increase catches above the 2004 level for chub mackerel. For bonga the Working Group recommended as a precautionary measure that the catch level should not exceed the average over the last five years and for anchovy the catch level should not exceed the average over the last three years. -

No results found.The twentieth session of the FAO Working Group on the Assessment of Small Pelagic fish off Northwest Africa was postponed until 2021 due to the global pandemic situation in 2020. The 2021 meeting was divided into two digital sessions, and updated the assessments to 2020 (or 2019, if no 2020 data were available). A separate digital meeting was convened to discuss 2019 surveys for the region from the R/V Dr Fridtjof Nansen and review the progress of research using the data collected from these surveys. La vingtième session du Groupe de travail de la FAO sur l'évaluation des petits pélagiques au large de l'Afrique du Nord-Ouest a été reportée à 2021 en raison de la situation pandémique mondiale en 2020. La réunion de 2021 a été divisée en deux sessions numériques et a mis à jour les évaluations jusqu'en 2020 (ou 2019, si aucune donnée 2020 n'était disponible). Une réunion numérique distincte a été convoquée pour discuter les campagnes effectuées en 2019 par N/R Dr Fridtjof Nansen dans la région et examiner les progrès de recherches à l'aide des données collectées à partir de ces campagnes.
