Ono is a mackerel-like fish growing up to 100 lbs in weight, but more generally caught at anything between 10 and 40 lbs. It is a very fast fish, reaching speeds of up to 50 mph, feeding on flying fish, scad and small tuna. Ono generally do not travel in schools but may gather at food sources. They are found in tropical and warm temperate waters. They have a lean, light flaky texture. The best are line-caught between May and October in Pacific waters off South and Central America or Hawaii. Because it is a lean fish it should only be very lightly cooked and poaching benefits its texture.
