Book excerpt: The Group assessed the status of the small pelagic resources in Northwest Africa and make projections on the development of the status of the stocks and on future effort and catch levels. As a precautionary measure, the catch level for this species should not exceed the average over the last three years of 115 000 tonnes. For bonga, the recommendation from 2006 is maintained as no new information is available on this species, and the Working Group recommended that the catch level should not exceed 42 000 tonnes. - Le Groupe a examine l'etat actuel des ressources de petits pelagiques en Afrique nord occidentale en fait des projections sur le developpement, l'effort futur et les niveaux de capture. Comme mesure de precaution, le niveau de capture pour cette espece ne devrait pas depasser la moyenne de 115 000 tonnes des trois dernieres annees. Pour l'ethmalose, la recommandation de 2006 est maintenue car aucune information nouvelle n'est disponible pour cette espece et le Groupe de travail a recommande que le niveau de capture ne depasse pas 42 000 tonnes"

Meeting and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2011 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Working Group used dynamic production models for all stocks. An index of environmental quality has been introduced in the production models since 2005. For most of the stocks, the time series from the acoustic surveys with the R/V DR. FRIDTJOF NANSEN and national research vessels are used as the index of abundance in the assessments and future assessments would therefore depend on the continuation of the time series by the local research vessels. The Norwegian research vessel, DR. FRIDTJOF NANSEN surveyed the subregion from 1995 to 2006, carrying out acoustic surveys during the months October-December each year. In addition, from 2001 to 2003, the vessel carried out acoustic surveys covering the same area from May to July. From 2004 to 2006, intercalibrations and parallel surveys were carried out between R/V DR.

The advice for the stocks are given in relation to the agreed reference points and on basis of the projections for the next five years.

Book excerpt: The Workshop on the Age Estimation of Sardine and Sardinella in Northwest Africa was organized in Casablanca, Morocco, from 4 to 9 December 2006. The Workshop was funded by project GCP/INT/730/NOR "International Cooperation with the Nansen Programme. Fisheries Management and Marine Environment" and organized by FAO and the National Institute of Fisheries Research (INRH). Altogether 15 scientists from seven countries and FAO participated. The Workshop reviewed and discussed the results of an otolith exchange that had been carried out in 2006 and which included both sardine and sardinella otoliths from different locations. The final outcome of the meeting consisted of revised agreed guidelines for the preparation and interpretation of sardine and sardinella otoliths. A new otolith exchange was initiated just after the Workshop to consolidate results.

Meeting and published by Food & Agriculture Org.. This book was released on 2006 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 addition of two chapters, one on bonga (Ethmalosa fimbriata) and one on anchovy (Engraulis encrasicolus). A separate section is devoted to each of the main groups of species (sardine, sardinella, horse mackerel, chub mackerel, bonga and anchovy). For each of these, standardised information is given on stock identity, fisheries, abundance indices, sampling, biological data, assessment, management recommendations and future research. In the absence of reliable length and/or age compositions, the Working Group used production models for all stocks. 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 unanticipated 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 (600 000 tonnes). 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 of 400 000 tonnes (2004). As a precautionary approach, the Working Group recommended not to increase catches above the average level of the last five years for the horse mackerels (80 000 tonnes for Trachurus trachurus and 170 000 tonnes for T. trecae) and not to increase catches above the 2004 level for chub mackerel (220 000 tonnes). For bonga the Working Group recommended as a precautionary measure that the catch level should not exceed the average over the last five years (42 000 tonnes) and for anchovy the catch level should not exceed the average over the last three years (160 000 tonnes). In formulating the results of the assessments, the Working Group noted that it lacked a set of uniform reference points and management objectives for all stocks in the area. The Group noted that the selection of appropriate reference points required more time than was available during the meeting. It was therefore decided that some members will look further into this problem, working by correspondence, and present a working paper at the 2006 meeting. At that meeting the Working Group will attempt to agree on a common policy concerning the way it presents its management advice for the various stocks.
