Barred Yellowtail Scad

Overview

The Barred Yellowtail Scad is an abundant, small inshore marine fish belonging to the jack family, Carangidae. It is the sole member of its genus and is widely distributed across tropical waters of the Indo-Pacific region. These fish are frequently encountered in coastal environments, often forming schools in midwater areas.

Appearance

This species is distinguished from other similar jacks by a well-developed adipose eyelid and unique finlet-like extensions on the final rays of both the dorsal and anal fins. Its body shape is typical of the carangid family, streamlined for active swimming.

Distribution & habitat

The species has a broad range extending from the Red Sea and the east coast of Africa across to the Hawaiian Islands and Samoa. Its northern limit reaches Japan, while its southern range includes the Arafura Sea and northern Australia. They are commonly found in coastal bays, mangroves, and near coral reefs.

Biology & behavior

Barred Yellowtail Scad are primarily diurnal and are known for their active, fast-swimming behavior in midwater columns. While they often congregate in schools, individuals may also be observed swimming singly. In certain regions, such as Hawaii, these fish are known to enter protected bays specifically for spawning purposes.

Feeding

As active predators, they feed primarily on a diet of small crustaceans and various planktonic invertebrates, including copepods. They have also been documented consuming cephalopods, utilizing their speed to pursue zooplankton in the water column.
