Guides Who Fish This Species

About Bullet Tuna

The bullet tuna, also known as bullet mackerel, is a saltwater fish with a bluish back turning to deep purple on the head. While the fish is dark bluish above, it has a silvery belly. You can know it by its two dorsal fins and short, purple pectoral fins. The fish also has a scaleless area with a pattern of fairly broad, vertical bars. The bullet tuna’s diet mostly consists of anchovies, planktons, fish larvae, and small cephalopods (e.g. squid, cuttlefish). 


Interesting Facts on Bullet Tuna

  • Compared to the bigger yellowfin or bluefin tuna, the bullet tuna species is smaller and more slender. 
  • The largest recorded size of this fish is 20 inches found in the East Atlantic. Because of its relatively smaller size, the bullet tuna often moves in schools. 
  • It is a highly migratory species which is why you can find this fish worldwide in tropical and subtropical waters. 
  • Although they have their diet of smaller fish, cannibalism is common in the bullet tuna species. 
  • Bullet tunas are considered important prey for commercial tunas because of their abundance.


Bullet Tuna Size 

The maximum length of a bullet tuna is 20 inches. These relatively larger catches are mostly found in Japan, one of the best places this fish can be caught. On average, the size of this fish species is 12 to 14 inches. 


Habitat and Distribution  

The bullet tuna is a circumtropical species which means that they can be typically caught in coastal waters and around islands. Anglers can fish for them in equatorial areas of the Atlantic, Indian, and Pacific Ocean. The bullet tuna is so widely distributed that you can find it as far north as Norway and as far south as the waters of South Aftrica. Fishing for the species has been recorded from the Gulf of Maine, east coast of North America, and Mar del Plata, off the Atlantic coast of South America.
