About Pacific Bluefin Tuna

• Pacific Bluefin Tuna (Thunnus orientalis) is a predatory species of tuna found widely in the northern Pacific Ocean.
• They are predatory and mainly eat squids and fish, such as sardines and anchovies, saury, herring, pompano, mackerel, hake, other tunas, and occasionally red crabs and krill. 
• They have black or dark blue dorsal sides, with a greyish-green iridescence.
• Their bellies are dotted with silver or grey spots or bands.
• They have a series of small yellow fins, edged in black, running from the second dorsal fin to the tail.
• They have relatively small eyes compared to other species of tuna.
• Most of the U.S. catch of Pacific bluefin tuna is within about 100 nautical miles of the California coast.
