In the United States the Tuna we typically find in the supermarket is Blue-fin or Yellow-fin tuna which has been net caught and is a schooling fish. Bonito tuna is significantly different in that it is line caught (and thus 100% dolphin safe) and of far superior quality than the other varieties. The meat is pale, firm, and moist with a truly delicious flavor. An interesting bit of trivia: canned blue- or yellow-fin tuna degrade in quality over time, while Bonito actually ages to become a delicacy like fine wine! Occasionally even vintage Bonito is available and fetches a higher price depending on the year produced.
