Whatis Kuromaguro?
There are two main categories of Kuromaguro: the Pacific Bluefin Tuna that is found in the Pacific Ocean, including Japan, and the Atlantic Bluefin Tuna, which lives in the seas from Boston on the east coast of the U.S. to the Mediterranean Sea. These two species have separate spawning locations and would never interact, but taxonomically, they are considered to be the same species.

What does Kuromaguro (Bluefin tuna) nigiri sushi taste like?
Kuromaguro, is considered as the best sushi item. Kuromaguro is in season in autumn and winter, while it is now available all through year thanks to advanced techniques of freezing and thawing. Maguro or tuna was considered as trash fish, not preferred during the Edo period and its fatty part was discarded. A maturing period of 4-10 days is set in order to bring out best in maguro such as a fine sourness and faint sweetness of fat. Its sleek, shiny looking deserves the title of “king of sushi”. The red flesh can be enjoyed in a variety of ways, either marinated in nikiri (called zuke),or rolled with maguro (called Tekkamaki).

Also called Hon maguro or shibi.

Fish farming is to hatch fish from eggs or to raise from juvenile fish right after hatching. Imported fish farming tuna, which is out in the market now, is actually fish fattening tuna that is raised bigger by feeding to full-grown fish. Fish fattening is to catch tuna by fixed net fishing method when they are skinny after egg-laying, and to fatten by feeding wild fish such as sardine and mackerel for three months.
