    Catch data are required for estimation of fishing mortality and for representation of fleet dynamics in the Lesser Antilles Pelagic Ecosystem (LAPE) model. The relative extractions by country and fleet type are used to investigate a range of policy scenarios (effort control) for management of shared stocks of pelagic species. A review by the LAPE project concluded that the use of the regional fisheries statistical system (CariFIS) database is still limited and that there remained dat a management issues which were major impediments to full implementation of CariFIS in national fisheries statistics systems. The additional time and technical assistance required to solve these problems are beyond the scope of the LAPE Project. It was necessary therefore to acquire the data by either extraction from international databases at Food and Agriculture Organization (FAO) and the International Commission for the Conservation of Atlantic Tunas (ICCAT) or a re-examination of country data holdings in the variety of software used (CariFIS, MS EXCEL, MS ACCESS). By preference, data were obtained from national sources; however, data were used from the international databases when individual country data proved inaccessible. This report documents the modifications to available data and assumptions made in arriving at estimates of total catch and value of pelagic fisheries in the LAPE region. It is not intended to give a detailed analysis of catches in the region, but rather to provide information in the format necessary

    Derivation of diet compositions in the Lesser Antilles Pelagic Ecosystem

    One of the medium-term objectives of the LAPE project is to enable fishery institutions in the Lesser Antilles to implement ecosystem approach to fisheries (EAF) management of the pelagic fisheries. An immediate objective of LAPE is the formulation of a food web model of the ecosystem to better understand the effects of fisheries on predator–prey relationships, and of the effects of food web dynamics on fisheries. This report presents average diet compositions of the 29 predator func tional groups, which include seabirds, marine mammals, turtles, fish, squid and zooplankton, in the LAPE model. The data were obtained through field sampling and analysis of stomach contents of a number of species of large and medium sized pelagic fish and marine mammals, as well as through a comprehensive search of published and unpublished literature. Data from 131 studies, of which about 8 percent were from the LAPE area, were used to derive the average diet compositions presented in this report. Despite the scarcity of data from within the LAPE area itself, a reasonable amount of data on same or similar species was available from adjacent areas in the Western Atlantic, including the Caribbean, and other areas mainly in the Atlantic. As expected, the availability of diet information was directly related to the commercial importance of the species. The analysis presented here does not consider differences in diet compositions arising from predator ontogenic changes and size, or seasonal changes in diets. A major problem encountered in a number of the studies was the low level of taxonomic disaggregation of the prey and relatively high proportion of unidentified prey items. Further studies are needed to better quantify diet compositions of the species in the LAPE ecosystem, including non-commercial species that might play an important ecological role.

    Report of the Regional Workshop on Ecosystem Approach to Fisheries Management in the Gulf of Guinea and first Steering Committee Meeting. Accra, Ghana, 23–26 October 2007 2010
    Also available in:

    A regional workshop on ecosystem approach to fisheries (EAF) for countries in the Guinea Current Large Marine Ecosystem (GCLME) area was held in Accra, Ghana, from 23 to 26 October 2007 together with the first Steering Committee meeting of the EAF-Nansen project “Strengthening the Knowledge Base for and Implementing an Ecosystem Approach to Marine Fisheries in Developing Countries (EAF Nansen GCP/INT/003/NOR)”. The objectives of the workshop were to introduce participants to EAF and th e EAF-Nansen project and to identify the activities to be carried out in the Gulf of Guinea under the project with focus on the year 2008. The workshop was attended by a total of 30 participants from 12 GCLME countries, the Fishery Committee of the West Central Gulf of Guinea (FCWC), the Ministry of Fisheries and Marine Resources of Namibia and FAO. In the introduction to EAF and the EAF-Nansen project, the need for applying an ecosystem approach to fisheries management, as reflect ed in the 2001 Reykjavik Conference on Responsible Fisheries in the Marine Ecosystem and in the Plan of implementation of the World Summit on Sustainable Development (WSSD), was highlighted. An overview of the key concepts and processes of the ecological risk assessment methodology was given and the experience gained and results obtained from the implementation of an EAF pilot project in the Benguela Current Large Marine Ecosystem area were presented. Based on a questionnaire that had been provided prior to the workshop, an overview of the main fisheries in the region (including their social and economic importance), existing institutional arrangements in support to fisheries management and perceived key challenges that managers of these fisheries face in relation to ecosystem sustainability were discussed. For practical exercises the participants worked in three subgroups (northern, central and southern countries) with each group selecting a specific fishery (shrim p trawl fishery by the northern and southern groups, the beach seine fishery by the central group), defining its global and specific objectives and working through issue identification for the selected fishery. Participants found the workshop extremely useful, commented extensively on the novel approach to management that the EAF provides and suggested that the work of the subregional groups should concentrate first on the fisheries dealt with during the workshop. They asked that the E AF-Nansen project document be sent officially to the respective countries for information and as a means of asking for national support, including co-financing.
