The Atlantic bonito is a fast-swimming predator found in the Atlantic Ocean, Mediterranean Sea, and Black Sea. It supports commercial fisheries and sport angling, valued for its tuna-like flesh in regional cuisines.

Share on WhatsApp

  • Reaches 75 cm in length and weighs up to 6 kg
  • Spawns in June with juveniles appearing by September
  • Distinctive dark oblique stripes on the back
  • Popular food fish in the Mediterranean region
  • Often caught as bycatch in tuna fisheries

What it is

This species belongs to the mackerel family and resembles tuna in appearance but has a more compressed body. Its scales cover the entire body, with larger scales near the pectoral fins and along the lateral line. The dorsal fins sit close together or have a small gap between them. Adults reach lengths of 75 centimetres and weigh up to six kilograms. Dark oblique stripes run down its back, distinguishing it from similar species with horizontal markings.

Where it lives

It inhabits shallow waters across the Atlantic Ocean, including the Mediterranean and Black Seas. Off the coast of New York City, it is a common offshore presence. The fish shares these waters with the striped bonito, which ranges as far north as Cape Cod. While both species occupy similar habitats, the Atlantic bonito is generally larger and more widespread in these regions.

How it lives

A powerful swimmer, this fish travels in large schools. It earns the local name skipjack due to its tendency to leap from the water, though this name often refers to a different tuna species. Its diet consists mainly of other fish such as mackerel, menhaden, and sand lances, as well as squid. This predatory behaviour supports its role as a strong competitor in coastal ecosystems.

Breeding and life cycle

Spawning occurs in June. By September, young specimens measuring 12 to 15 centimetres are caught off Long Island. This timeline indicates rapid early growth during the summer months. The presence of these juveniles in late summer suggests successful reproduction earlier in the season within these coastal waters.

Fish and people

Anglers value it as a game fish, often catching it while trolling for larger tuna. Commercial fishermen capture it using pound nets or as bycatch in traditional Almadraba tuna traps. In the Mediterranean, it is a popular food fish. Small individuals are grilled as steaks, while larger ones are preserved as lakerda. It is also canned or prepared as escabeche in Spain and Algeria.

Questions people ask about Atlantic bonito

Is Atlantic bonito the same as skipjack tuna?

No, they are different species. Atlantic bonito is sometimes called skipjack locally because it jumps, but true skipjack tuna is a different fish. Bonito has oblique stripes and lacks teeth on the roof of the mouth.

How is Atlantic bonito eaten?

It is popular in the Mediterranean. Small fish are grilled as steaks, while larger ones are cured into lakerda. It is also canned, baked, or preserved in escabeche, a marinade that keeps it fresh for about a week.

Where can you find Atlantic bonito?

They live in shallow waters of the Atlantic Ocean, Mediterranean Sea, and Black Sea. They are common offshore near New York City and are often found in large schools in these temperate regions.
