Book Description
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"

Book Description
The fourth meeting of the FAO/CECAF Working Group on the Assessment of Small Pelagic Fish – Subgroup South was held in Elmina, Ghana from 12-20 September 2018. 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.

Book Description
During this year's meeting the emphasis was on updating the database as well as knowledge of assessment methods within the group. At the beginning of the meeting a two-day course in assessment methodology was held. A separate section is devoted to each main group of species (sardine, sardinellas, horse mackerels and mackerel). For each of these, actualized information until 2001 is given on stock identity, the fisheries, catch and effort, biological data and abundance indices.--Publisher's description.

Book Description
The Group assessed the status of the small pelagic resources in Northwest Africa and made projections on the development of the status of the stocks and on future effort and catch levels. The advices for the stocks are given in relation to the agreed reference points and on basis of the projections for the next five years.--Publisher's description.

Book Description
Ecosystem valuation is a process that assigns a monetary value to the benefits that are provided by an ecosystem and its ecosystem services. This study carries out the economic valuation of marine and estuarine coastal ecosystem services in the Canary Current Marine Ecosystem (CCLME). The CCLME stretches along the coast of Western Africa, from Morocco to Guinea, and is characterized by high biological productivity due to the upwelling of deep, cold oceanic waters along this coast. This also supports a high abundance of fish resources (both pelagic and demersal) and overall high biodiversity. This study reviews and assesses ecosystem services provided by the marine areas, coastal mangroves and seagrass meadows. These coastal areas not only provide habitats for some commercial fish species, but also feeding grounds, nurseries, or refuges. Therefore, mangroves and seagrasses can play an important role in maintaining fish stocks. L’évaluation des écosystèmes est un processus qui attribue une valeur monétaire aux avantages offerts par un écosystème et ses services écosystémiques. Cette étude cherche à réaliser une évaluation économique des services des écosystèmes côtiers marins et estuariens dans l’écosystème marin du courant des Canaries (CCLME). Le CCLME s’étend le long des côtes de l’Afrique de l’Ouest, du Maroc à la Guinée, et se caractérise par une productivité biologique élevée due à la remontée d’eaux océaniques froides et profondes (upwelling) le long de cette côte. Cela favorise également une grande abondance de ressources halieutiques (pélagiques et démersales) et une biodiversité globale élevée. Cette étude examine et évalue les services écosystémiques fournis par les zones marines, les mangroves côtières et les herbiers marins. Ces zones côtières fournissent non seulement des habitats pour certaines espèces de poissons commerciales, mais constituent également des aires d’alimentation, de nourriceries ou des refuges. Par conséquent, les mangroves et les herbiers marins peuvent jouer un rôle important dans le maintien des stocks de poissons.

Book Description
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.

Book Description
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.
