“Until the 1970s, bluefin tuna was a literal trash fish. If it wasn’t put into cat food, sport fishermen paid to have it hauled off to dumps (after taking a smiling photo next to their strung-up carcasses). Until the mid-1900s, tuna’s reputation was so bad in Japan that it was referred to as neko-matagi, food too low for even a cat to eat.” Sadly for bluefin, they got a lot more popular. And now bluefin tuna is endangered. Give a man a fish and you feed him for a day; teach a man to fish and you could soon run out of fish.
