Yellow Spotted Trevally

Overview

The yellow spotted trevally is a large, predatory marine fish widely distributed across the tropical and subtropical waters of the Indo-Pacific. Often found near rocky and coral reefs, this species is known for its impressive size and is highly regarded by anglers as a challenging sportfish.

Distribution & habitat

This species inhabits the western Indo-Pacific, ranging from South Africa in the west to Japan and Australia in the east. While it typically prefers inshore rocky and coral reef environments, it is also occasionally encountered over deep offshore sand banks at depths reaching 100 meters.

Appearance

The yellow spotted trevally features a subovate, compressed body that becomes more elongate and slightly subcylindrical as the fish matures. Adults are characterized by an iridescent blue-green upper body that fades to a silvery tone below, accented by numerous small gold or brassy spots along the dorsal half. Larger individuals may also display several irregular dark blotches on their flanks. The head profile becomes increasingly steep and angular with age, and the mouth is positioned distinctly below the level of the eye.

Biology & behavior

These fish are typically observed swimming alone or in small to large schools. They are active predators that forage for food along the seafloor and reef structures. While their reproductive habits are not extensively documented, observational evidence suggests that they may spawn in aggregations, potentially during the summer months in certain parts of their range.
