    An Ecopath with Ecosim model describing the pelagic ecosystem of the waters surrounding the Lesser Antilles islands in the eastern Caribbean was constructed. It incorporates data derived from published sources as well as unpublished databases and data collection activities conducted by the FAO project

    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of large and medium sized pelagic fish and marine mammals, as well as through a comprehensive search of published and unpublished literature.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.

    The second evaluation of the small and medium pelagic fishery in the United Republic of Tanzania was carried out in November 2021, by a group of multidisciplinary experts, including fisheries managers, scientists and fishers. The first evaluation was carried out almost two years after the first benchmark scoring of the fishery, conducted in January 2020, shortly after the start of the project to support the implementation of the small and medium pelagic management plan in the country. The aim was to assess the progress made since the last scoring. The ecosystem approach to fisheries implementation monitoring tool (EAF IMT) was developed to allow the monitoring of the progress of the EAF implementation and sustainable fisheries management. It allows the implementation of the EAF to be evaluated at different levels: at the level of a particular issue, to the level of EAF component, up to the entire fishery level.
