[2] This fish has been mostly found schooling in the open ocean[3] and live up to depths of 110 meters.

It has ten or eleven stripes on its back running obliquely from the dorsum forward, and fifteen or more rakers below the angle on the first gill.

They can migrate up to 600 miles and move south in the winter where temperatures are warmer and north for the summer.

From January to June, during their spawning season, they have been found to eat equal amounts of mackerel and squid.

Estimating the populations of this species is also difficult due to them moving around a lot and quickly.

[7] It is caught by trolling and still fishing, using feather lures, spoons, or live bait.

Although there is not a lot of information about this species’ role in the ocean, it does serve as a food source for predators such as swordfish, bluefin tuna, striped marlin, sea lions, and dolphins as well as some sharks.

[7] Mature Pacific bonito are most commonly found in open ocean environments of up to 300 ft and swim in schools.

[7] They exhibit slight sexual dimorphism during mating and courtship, but only during those times and are otherwise indistinguishable.

[13] In typical years, the Northern part of this species’ population resides in Southern California during spring and summer.
