Sardinella aurita

Sardinella aurita
Name	Round sardinella
Taxon	Sardinella aurita
Authority	Valenciennes, 1847

Sardinella aurita is a small pelagic clupeid fish known commonly as the round sardinella, widely distributed in tropical and subtropical coastal waters and forming large schools exploited by commercial fisheries. It is ecologically important as prey for many predators and economically significant in artisanal and industrial fisheries across the Atlantic and Indo-Pacific regions. Research on its population dynamics, stock assessments, and trophic role intersects with work by international organizations and regional fisheries bodies.

Taxonomy and Nomenclature

Described by Achille Valenciennes in 1847, the species is placed in the family Clupeidae alongside genera treated by taxonomists referenced in works associated with the Natural History Museum, Smithsonian Institution, and Muséum national d'Histoire naturelle; its nomenclature has been discussed in faunal surveys by the International Commission on Zoological Nomenclature and catalogues used by the Food and Agriculture Organization of the United Nations and regional bodies such as the International Commission for the Conservation of Atlantic Tunas. Historical synonomies and diagnostic characters appear in monographs linked to the British Museum and publications from the American Fisheries Society and the European Commission's scientific services. Taxonomic treatments frequently cite specimen records from the Global Biodiversity Information Facility, the Ocean Biogeographic Information System, and museum collections at institutions like the California Academy of Sciences and the Natural History Museum, London.

Description and Identification

Adults typically reach lengths documented in field guides used by the FAO, NOAA Fisheries, and the Gulf and Caribbean Fisheries Institute, exhibiting the streamlined, compressed body shape characteristic of Clupeidae observed in keys from the Royal Society and Zoological Society of London. Diagnostic external features are recorded in identification manuals by the Food and Agriculture Organization, including a silver flank with a darker dorsum and a series of scutes and fin ray counts used in dichotomous keys developed by the American Museum of Natural History, Muséum national d'Histoire naturelle, and regional laboratories. Morphometric and meristic data used in species delineation appear in regional atlases produced by the European Union, Instituto de Investigaciones Marinas, and the Instituto Oceanográfico de Venezuela, and are compared in comparative studies published in journals like Nature, Science, and the Journal of Fish Biology.

Distribution and Habitat

The species' Atlantic distribution, described in range maps curated by the International Union for Conservation of Nature, includes coastal waters off West Africa, the Gulf of Mexico, the Caribbean Sea, and parts of the western Atlantic reported in surveys by NOAA, the Caribbean Community (CARICOM), and the African Union's fisheries programs. Records of presence in the Mediterranean and Indo-Pacific appear in checklists and regional assessments by the Mediterranean Science Commission (CIESM), the Indian Ocean Tuna Commission, and national services such as Brazil's Ministério da Agricultura and Ghana's Fisheries Commission. Typical habitats documented in habitat assessments by the United Nations Environment Programme, the World Wide Fund for Nature, and regional marine institutes include surface to midwater coastal shelf zones, estuaries monitored by the European Environment Agency, and upwelling areas studied by research teams from Scripps Institution of Oceanography and the Woods Hole Oceanographic Institution.

Biology and Ecology

Sardinella aurita forms dense pelagic schools whose behavior has been analyzed in ecological studies published by the Royal Society, Smithsonian Tropical Research Institute, and the Max Planck Institute; these schools influence trophic interactions with predators documented in work by the Zoological Society of London, the North Atlantic Fisheries Organization, and the Convention on International Trade in Endangered Species when considering food webs involving species referenced in National Oceanic and Atmospheric Administration reports. Diet analyses using methods developed at universities such as Harvard, Oxford, and the University of Cape Town show planktonic feeding on zooplankton and phytoplankton described in publications by the International Council for the Exploration of the Sea and the South African National Biodiversity Institute. Reproductive patterns, larval dispersal, and growth studies appear in fisheries science literature from the University of Bergen, CSIRO, and the Philippine Fisheries Development Authority, with population modeling referenced in reports by the Food and Agriculture Organization, the Intergovernmental Panel on Climate Change, and regional stock assessment workshops.

Fisheries and Economic Importance

Sardinella aurita supports artisanal and industrial fisheries that are central to coastal economies cited in reports by the Food and Agriculture Organization, the World Bank, and regional development banks such as the African Development Bank and the Inter-American Development Bank. Harvest methods recorded by national agencies like Brazil's Ministério da Pesca, Senegal's Institut Sénégalais de Recherches Agricoles, and Peru's Instituto del Mar include purse seines, lampara nets, and small-scale gillnets described in technical manuals from the FAO, NOAA Fisheries, and the European Commission. Processing and trade of canned, salted, and fresh product enter markets tracked by the World Trade Organization, UN Conference on Trade and Development, and national ministries of commerce, and are subject to quality standards from Codex Alimentarius, ISO, and national food safety authorities.

Conservation and Management

Management measures and conservation status have been assessed in regional fisheries management plans developed by bodies such as the International Commission for the Conservation of Atlantic Tunas, the Food and Agriculture Organization, and subregional fisheries commissions; stock assessments and recommendations are prepared by research institutes including the Instituto Español de Oceanografía, the Institute of Marine Research (Norway), and the Centre for Environment, Fisheries and Aquaculture Science. Threats from overfishing, habitat alteration, and climate change are highlighted in reports by the Intergovernmental Panel on Climate Change, the United Nations Environment Programme, and the World Wildlife Fund, prompting measures like catch limits, gear restrictions, and monitoring protocols implemented by national fisheries agencies and multilateral agreements such as the Convention on Biological Diversity and regional fisheries management organizations. Adaptive management, community-based co-management, and international cooperation are discussed in policy briefs from the World Bank, Food and Agriculture Organization, and conservation NGOs such as Conservation International and The Nature Conservancy.
