ProjectProgramme / project reportAcoustic biomass estimates of pelagic forage species in the offshore waters of the Lesser Antilles
Scientific Basis for Ecosystem-Based Management in the Lesser Antilles Including Interactions with Marine Mammals and Other Top Predators (LAPE)
2008Also available in:
No results found.A recently completed survey of the Lesser Antilles pelagic ecosystem used a combination of multi-frequency acoustics and pelagic trawling to locate and estimate the biomass of forage species. Stratified zig-zag transects were used to investigate an area of 610 000 km2 in the waters east and west of the Lesser Antilles from Antigua to Trinidad. Distinct pelagic layers and aggregations observed acoustically were sampled using a multiple (3) codend pelagic trawl. Pelagic organisms were identified to the lowest taxon possible and categorized by the presence or absence of a swim bladder. The acoustic data were grouped into nine broad categories based on the multi-frequency returns considering backscattering strength, aggregation appearance, depth and time of day. The resulting acoustic density was converted to indicative biomass density (kg/m2) by application of target strength estimates from published sources. Relative abundance and composition of the nine acousti c categories for the 18 and 38 kHz frequencies are presented. The spatial distribution of these broad categories displayed several distinct patterns. There was an inshore-offshore segregation of some groups throughout the survey area, but there was little sign of latitudinal gradients in distribution of these broad groupings. In the open pelagic waters, diel vertical migrations were observed by several identifiable acoustic categories, particularly mesopelagic fish (largely Myctoph ormes and Stomiiformes), and squids. Dusk and dawn vertical excursions were observed daily between depths from 500 m to less than 100 m. -
ProjectProgramme / project reportDerivation of diet compositions in the Lesser Antilles Pelagic Ecosystem
Scientific Basis for Ecosystem-Based Management in the Lesser Antilles Including Interactions with Marine Mammals and Other Top Predators (LAPE)
2008Also available in:
No results found.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. -
ProjectProgramme / project reportCetacean surveys in the Lesser Antilles - 2000-2006
Scientific Basis for Ecosystem-Based Management in the Lesser Antilles Including Interactions with Marine Mammals and Other Top Predators (LAPE)
2007Also available in:
No results found.Sighting surveys are the principal means of obtaining information about the species, abundance, distribution and movements of marine mammals and other air-breathing groups. During the course of the project a number of cetacean sighting surveys were conducted in both near-shore (small-scale) and offshore (large-scale) waters of the Lesser Antilles Pelagic Ecosystem (LAPE). In addition, the results from additional surveys, conducted in the same area for the period 2000-2003, were compi led and incorporated into the present analysis. With one exception, statistical analysis of the surveys was not possible due to small numbers of sightings. In the one case where an analysis was completed it was based on species aggregated into groups of similar behaviour (for sighting purposes). Estimates of the abundance of the aggregate groups had high coefficients of variation, ranging from 0.34 to 0.89. The species identified in the surveys were all known to be present in the reg ion although one important group of cetaceans reported to be in the region, the killer whales (e.g. Orcinus orca, Pseudorca crassidens, Feresa attenuate), was not observed during any of the LAPE project surveys.

Book (stand-alone)High-profileTechnical Cooperation Programme 2019 Report
Catalysing results towards the Sustainable Development Goals
2019Also available in:
No results found.FAO’s Technical Cooperation Programme (TCP) is one of the mechanisms to respond to countries’ most pressing needs for technical assistance and effectively pursue the achievement of the Sustainable Development Goals (SDGs). The 2019 Report of the Technical Cooperation Programme introduces a new series of annual reports that provide FAO Members, governments, donors, beneficiaries and other stakeholders with evidence of the impact of the work carried out by FAO through the TCP. Prepared by the Outreach, Marketing and Reporting Unit (PSRR), in close collaboration with the TCP Coordination Unit in the Office of the Assistant Director-General (ADG-PS), the first in the series presents and assesses the achievements and catalytic role of TCP-funded projects. Based on a review of the TCP projects operationally closed during 2018 and interviews with lead technical officers, technical officers at FAO headquarters, budget holders and FAO country representatives, the report provides details on the characteristics, typical interventions and results of the programme, and features a select number of in-depth stories to highlight the tangible and lasting results of the programme’s catalytic work. -

Book (series)Technical reportReport of the Twelfth Meeting of the Regional Commission for Fisheries (RECOFI) Working Group on Fisheries Management
Virtual meeting, 4-5 October 2021
2023Also available in:
No results found.The twelfth meeting of the Regional Commission for Fisheries (RECOFI) Working Group on Fisheries Management (WGFM) was held virtually, from 4 to 5 October 2021. The meeting was convened by RECOFI and FAO and attended by 36 participants from the following seven RECOFI member countries: Iraq, Iran (Islamic Republic of), Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates in addition to the FAO Secretariat. Bahrain did not attend. The meeting agreed with the recommendations from the workshop on Minimum Data Reporting (MDR) in July and noted that in terms of reviewing and reassessing the current MDR indicators, information could be collected using the previously noted tables on current work on RECOFI priority species, in particular the information regarding management measures and targeted fisheries. The WGFM noted the importance of having a variety of expertise providing input to FIRMS; it was acknowledged that while the Focal Point may not be an expert in all areas, they should consult with colleagues with relevant expertise as needed. Additionally, the meeting recognized it could be useful for the Focal Point and Alternate Focal Point to have complementary expertise to facilitate all the needed information. The meeting noted the challenge of reporting a stock as national or shared, due to it not being known definitively for each species. This has resulted in some inconsistencies in reporting across RECOFI countries on both RECOFI Priority Species as well as other species commonly reported by RECOFI member countries on the SDG 14.4.1 questionnaire. The meeting noted that RECOFI could play a role by working with member countries to jointly develop and complete a table on certain stocks which would assist member Countries in filling out the SDG 14.4.1 questionnaire. The WGFM is proposing a template which, once adopted by the Commission, will be used by the Secretariat to fill out according to the data already submitted by four RECOFI Countries which submitted their SDG14.4.1 questionnaire as part of the first inquiry launched by FAO in November 2019. The completed table would then be recirculated to RECOFI member countries in the endeavour to facilitate consistency in reporting when completing future versions of the SDG 14.4.1 Questionnaire. Countries which have not yet reported on the SDG14.4.1 questionnaire will be invited to provide inputs to that table. The WGFM acknowledged the recommendations of the workshop and reaffirmed the request to receive the SDG 14.4.1 questionnaire in Arabic.
