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. -

Book (series)Technical studySmall fish for food security and nutrition 2023
Also available in:
No results found.Food insecurity, hunger and malnutrition have been on the rise in recent years, due to disruptions such as the COVID-19 pandemic, increasing climate shocks and conflicts. Decades of steady progress to reduce food insecurity and malnutrition were often attributed to increased food production and intensification of few food staple crops and livestock, however more recent focus has shifted to the role of small-scale producers and the importance of diverse and nutritious foods. This technical paper brings focus to the often overlooked ‘small fish’ which play an integral role in the food security, nutrition and livelihoods of the small-scale fisherfolk who harvest, process, market, trade and distribute small fish to communities near and far from water bodies. The technical paper explores the various dimensions of the ‘small fish food system’, addressing drivers, scales, interactions and multiple outcomes and trade-offs, such as that of small fish used for food versus feed. Throughout, the work applies a human-centred perspective, emphasizing how people are involved in various stages of a food system, and how interactions and networks between them play a role in food system dynamics and outcomes. It is also emphasizes how people play multiple roles within a food system, and thus should not be narrowly defined as fishers, processors or consumers. The paper documents project implementation and lessons from the FAO subprogramme titled “Implementing the Small-Scale Fisheries Guidelines for gender equitable and climate resilient food systems and livelihoods”, and the SmallFishFood, Ikan-F3, Dried Fish Matters, and Fish4Food projects led by the University of Bergen, the University of Amsterdam and the University of Manitoba. -

Book (series)FlagshipThe State of World Fisheries and Aquaculture 2022
Towards Blue Transformation
2022The 2022 edition of The State of World Fisheries and Aquaculture coincides with the launch of the Decade of Action to deliver the Global Goals, the United Nations Decade of Ocean Science for Sustainable Development and the United Nations Decade on Ecosystem Restoration. It presents how these and other equally important United Nations events, such as the International Year of Artisanal Fisheries and Aquaculture (IYAFA 2022), are being integrated and supported through Blue Transformation, a priority area of FAO’s new Strategic Framework 2022–2031 designed to accelerate achievement of the 2030 Agenda for Sustainable Development in food and agriculture. The concept of Blue Transformation emerged from the Thirty-fourth Session of the FAO Committee on Fisheries in February 2021, and in particular the Declaration for Sustainable Fisheries and Aquaculture, which was negotiated and endorsed by all FAO Members. The Declaration calls for support for “an evolving and positive vision for fisheries and aquaculture in the twenty first century, where the sector is fully recognized for its contribution to fighting poverty, hunger and malnutrition.” In this context, Part 1 of this edition of The State of World Fisheries and Aquaculture reviews the world status of fisheries and aquaculture, while Parts 2 and 3 are devoted to Blue Transformation and its pillars on intensifying and expanding aquaculture, improving fisheries management and innovating fisheries and aquaculture value chains. Blue Transformation emphasizes the need for forward-looking and bold actions to be launched or accelerated in coming years to achieve the objectives of the Declaration and in support of the 2030 Agenda. Part 4 covers current and high-impact emerging issues – COVID-19, climate change and gender equality – that require thorough consideration for transformative steps and preparedness to secure sustainable, efficient and equitable fisheries and aquaculture.
