Jack mackerel

Jack mackerel is a common name for a variety of species within the mackerel family, specifically those in the genus Trachurus. These species are found in both the Atlantic and Pacific oceans, and are known for their distinctive, elongated bodies and large eyes.

Description

Jack mackerels are medium-sized fish, typically reaching lengths of 30 to 50 centimeters. They have a streamlined, elongated body shape, which allows them to swim at high speeds. Their bodies are predominantly silver in color, with a blue or green tint on the back. The most distinctive feature of jack mackerels is their large eyes, which are adapted for hunting in low-light conditions.

Distribution and habitat

Jack mackerels are found in both the Atlantic and Pacific oceans. In the Atlantic, they are found from Norway to Morocco, and in the Pacific, they are found from Alaska to Chile. They prefer temperate waters and are typically found at depths of 100 to 200 meters, although they can be found at depths of up to 500 meters.

Diet

Jack mackerels are predatory fish, feeding primarily on small fish and invertebrates. Their large eyes allow them to hunt in low-light conditions, and they are known to form large feeding schools.

Commercial importance

Jack mackerels are of significant commercial importance. They are caught in large numbers for their meat, which is considered a delicacy in many cultures. In addition to being consumed fresh, jack mackerel is also often canned or smoked.

Conservation status

While some species of jack mackerel are abundant, others are considered endangered due to overfishing. Conservation efforts are in place to protect these species and ensure their survival.
