Global research collaboration on small pelagic fish (SPF) was initiated by an international symposium titled “The Expert Consultation to Examine Changes in Abundance and Species Composition of Neritic Fish Resources” organized in 1983 by the Food and Agriculture Organization (FAO) and the Intergovernmental Oceanographic Commission (IOC) in San José, Costa Rica (FAO Fisheries Report 291, 1983). The GLOBEC Regional Program on Small Pelagic Fish and Climate Change (SPACC) facilitated this global collaboration from 1994 to 2010, and culminated with the publication of a review book "Climate Change and Small Pelagic Fish". In the most recent decade, ICES and PICES have co-sponsored two symposia on SPF, including “Forage fish interactions: Creating the tools for ecosystem-based management of marine resources” in 2012 (Nantes, France), leading to 12 research articles in the ICES Journal of Marine Science (2014, Vol.71,
pp.1–152), and “Drivers of dynamics of small pelagic fish resources” in 2017 (Victoria, Canada), resulting in two special issues in Deep-Sea Research Part II (2019, Vol.159, pp.1–182; 15 articles) and Marine Ecology Progress Series (2019, Vol.617–618, pp.1–376; 22 articles). The 2017 SPF symposium re-confirmed the need to meet every 4 to 5 years to discuss, debate and collaborate to further improve the science-based advice required to sustainably manage SPF in an ecosystem context. Discussions at that symposium also led to the formation of the joint ICES/PICES Working Group on Small Pelagic Fish (ICES WGSPF and PICES WG 43) which held its first meeting in March 2020 in Copenhagen, Denmark.
