Disentangling global market drivers for cephalopods to foster transformations towards sustainable seafood systems

People and Nature, Volume 5, Issue 2, Page 508-528, April 2023., 2023
Abstract 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 ...
