The World Wide Fund for Nature warned in a recent report that illegal fishing for Bluefin tuna is pervasive in Europe in order to meet Japanese market demand. The caught tuna are transferred to cages in which they are fattened for six or seven months to meet Japanese market standards for “sushi†and “sashimi,†the report says.
“Japanese consumers have no clues to know whether or not the tuna they are eating is illegally caught,†said Arata Izawa of WWF Japan. He said companies importing and distributing tuna should disclose all related information to the public.
