The little tunny is a small to medium-sized fish, typically reaching lengths of 85 cm (33 in) and weights of 7–10 kg (15–22 lb). It has a robust, streamlined body with a dark blue to black dorsal surface and a silvery white ventral side. The species is characterized by its wavy lines on the back and spots between the pectoral and ventral fins.

Distribution and habitat

The little tunny is widely distributed in the Atlantic Ocean, from Massachusetts to Brazil in the western Atlantic, and from the Bay of Biscay to South Africa in the eastern Atlantic. It is also found throughout the Mediterranean Sea. The species prefers warm, coastal waters and is often found near the surface.

Behavior

Little tunny feeding behavior

Little tunnies are known for their schooling behavior and are often seen in large groups. They are fast swimmers and are capable of reaching speeds of up to 40 miles per hour. The species is a carnivorous predator, feeding primarily on small fish, crustaceans, and cephalopods.

Reproduction

Little tunnies are oviparous, with spawning occurring in the warmer months. Females release eggs into the water column, which are then fertilized by males. The larvae are pelagic and undergo several developmental stages before reaching maturity.

Fishing and economic importance

The little tunny is not considered a major commercial species, but it is valued in recreational fishing. Anglers prize the species for its fighting ability and speed. It is often caught using trolling and live bait techniques.

Conservation status

Currently, the little tunny is not listed as threatened or endangered. However, like many marine species, it faces threats from overfishing and habitat degradation.
