Tuna is one of the most widely consumed fish in the world, yet few people know much about the animal beyond the can or the sushi platter.Tuna is one of the most widely consumed fish in the world, yet few people know much about the animal beyond the can or the sushi platter. This book, written with the assistance of artificial intelligence, traces the full story of the tuna: its biology and behaviour, the ocean ecosystems it inhabits, the fishing industries built around it, and the many ways it has been prepared and eaten across cultures and centuries. You will find chapters covering the main species, the science of migration, the history of canning, and the sustainability questions facing tuna populations today. The aim is straightforward: to give you a clear, readable account of a fish that matters both ecologically and gastronomically, from the deep ocean to the kitchen table.Tuna is one of the most widely consumed fish in the world, yet few people know much about the animal beyond the can or the sushi platter.
