“…According to our review, knowledge of the cephalopod food system is unevenly distributed across the value chain, as was found with previous cephalopod value chain analysis (e.g. Coronado et al, 2020; Rosales Raya & Berdugo, 2019). Typically, only some types of actors are included (but not always) in fisheries governance decision‐making (e.g.…”

Aquatic food systems are important contributors to global food security to satisfy an intensifying demand for protein‐based diets, but global economic growth threatens marine systems. Cephalopod (octopus, squid and cuttlefish) fisheries can contribute to food security; however, their sustainable exploitation requires understanding connections between nature's contributions to people (NCP), food system policies and human wellbeing. Our global literature review methodology examined what is known about cephalopod food systems, value chains and supply chains, and associated market drivers. For analysis, we followed the IPBES conceptual framework to build a map of the links between cephalopod market drivers, NCP and good quality of life (GQL). Then we mapped cephalopod food system dynamics onto IPBES (in)direct drivers of change relating to catch, trade and consumption. This research contributes knowledge about key factors relating to cephalopods that can support transitions towards increased food security: the value of new aquatic food species; food safety and authenticity systems; place‐based innovations and empowerment of communities; and consumer behaviour, lifestyle and motivations for better health and environmental sustainability along the food value chain. We outline requirements for a sustainable, equitable cephalopod food system policy landscape that values nature's contributions to people, considers UN Sustainable Development Goals and emphasises the role of seven overlapping IPBES (in)direct drivers of change: Economic, Governance, Sociocultural and Socio‐psychological, Technological, Direct Exploitation, Natural Processes and Pollution. We present a novel market‐based adaptation of the IPBES conceptual framework—our ‘cephalopod food system framework’, to represent how the cephalopod food system functions and how it can inform processes to improve sustainability and equity of the cephalopod food system. This synthesised knowledge provides the basis for diagnosing opportunities (e.g. high demand for products) and constraints (e.g. lack of data about how supply chain drivers link to cephalopod NCP) to be considered regarding the role of cephalopods in transformations towards a resilient and more diversified seafood production system. This social–ecological systems approach could apply to other wild harvest commodities with implications for diverse marine species and ecosystems and can inform those working to deliver marine and terrestrial food security while preserving biodiversity.

“…Finally, there are some key challenges that need to be addressed in order to improve our scientific understanding on the interlinkages between cephalopods fisheries and trade in the next years. A growing demand for cephalopods can lead to increased exploitation of stocks with implications for their environmental, social, and economic sustainability, in particular, in developing countries where corruption and IUU fishing practices are often the logical response to a lack of effective policy and regulatory frameworks 44 , 45 . Furthermore, the energy cost of fishing and transporting cephalopods through the complex trade links as well as the carbon sink prevented by the removal of cephalopods we have described from the oceans 46 , must also be considered in terms of sustainable cephalopods exploitation and carbon emissions.…”

The global trade in cephalopods is a multi-billion dollar business involving the fishing and production of more than ten commercially valuable species. It also contributes, in whole or in part, to the subsistence and economic livelihoods of thousands of coastal communities around the world. The importance of cephalopods as a major cultural, social, economic, and ecological resource has been widely recognised, but research efforts to describe the extent and scope of the global cephalopod trade are limited. So far, there are no specific regulatory and monitoring systems in place to analyse the traceability of the global trade in cephalopods at the international level. To understand who are the main global players in cephalopod seafood markets, this paper provides, for the first time, a global overview of the legal trade in cephalopods. Twenty years of records compiled in the UN COMTRADE database were analysed. The database contained 115,108 records for squid and cuttlefish and 71,659 records for octopus, including commodity flows between traders (territories or countries) weighted by monetary value (USD) and volume (kg). A theoretical network analysis was used to identify the emergent properties of this large trade network by analysing centrality measures that revealed key insights into the role of traders. The results illustrate that three countries (China, Spain, and Japan) led the majority of global market movements between 2000 and 2019. Based on volume and value, as well as the number of transactions, 11 groups of traders were identified. The leading cluster consisted of only eight traders, who dominated the cephalopod market in Asia (China, India, South Korea, Thailand, and Vietnam), Europe (the Netherlands, and Spain), and the USA. This paper identifies the countries and territories that acted as major importers or exporters, the best-connected traders, the hubs or accumulators, the modulators, the main flow routes, and the weak points of the global cephalopod trade network over the last 20 years. This knowledge of the network is crucial to move towards an environmentally sustainable, transparent, and food-secure global cephalopod trade.

“…Nevertheless, a growing demand for sheries resources can lead to increased exploitation of stocks with implications for the environmental, social, and economic sustainability of sheries in developing countries where corruption and illegal shing practices are often the logical response to a lack of effective policy and regulatory frameworks 31,32 . Furthermore, the energy cost of transporting products through the complex trade links as well as the carbon sink prevented by the removal of cephalopods we have described from the oceans 33 , must also be considered in terms of resource use and carbon emissions.…”

The global cephalopod trade is a multi-billion-dollar industry that involves fishing and captive breeding of a dozen species of high commercial value. It also contributes wholly or partly to the income and subsistence of thousands of families around the world. Despite its broad ecological, social, and economic importance, limited research has been conducted to describe the scope and scale of the global cephalopod trade. To date, there is no specific regulation, nor have tracking systems been implemented, to study the traceability of the global cephalopod trade at an international level. We provide, for the first time, a comprehensive description of the legal trade in cephalopods to understand who the key world players in the cephalopod seafood markets are. We analysed 20 years of records compiled by the United Nations COMTRADE database. The database contained 115,108 entries for squid and cuttlefish and 71,659 entries for octopus, including the product flow between traders (countries or territories) weighted by volume (kg) and monetary value (USD). Graph theoretic analysis was used to explore the emergent properties of this database through the analysis of different measures of centrality that provide insights on the key role of the traders in the network. Our findings show that most of the market movements between ca. 250 traders are led by three countries (China, Spain, and Japan), involving 11 clusters of traders based on the volume and value of cephalopod trade and number of transactions. The most important cluster, that dominates the cephalopod seafood market, is composed by 5 Asian countries (China, India, Republic of Korea, Thailand, and Vietnam), 2 European countries (the Netherlands and Spain) and the USA. This work identifies the traders that act as major exporters and/or importers, the modulators, intermediaries or accumulators, the best-connected traders, the principal flow routes and the weaknesses of the global cephalopod trade network. This network information is essential to advance towards a transparent and sustainable cephalopods world trade.
