Silver Trevally

Overview

The Silver Trevally (Pseudocaranx dentex) is a widely distributed, schooling fish found in tropical and warm temperate waters across the Atlantic, Mediterranean, Indian, and Pacific Oceans. Known for its speed and agility, this species is a popular target for anglers and is often associated with rocky reefs, coastal bays, and estuaries.

Appearance

This species features a deep, laterally compressed, oval-shaped body with a pointed snout and fleshy lips. Its coloration is typically greenish-blue or grayish on the back, fading to a silvery-white underside, often with a distinct yellow stripe running along the mid-side of the body. A small, characteristic black spot is located on the posterior edge of the operculum. The fins are generally yellow, with falciform pectoral fins and a deeply forked tail.

Distribution & Habitat

Silver Trevally are highly mobile and inhabit a variety of marine environments, ranging from shallow inshore waters and estuaries to the continental shelf. While juveniles are frequently found in shallow, sheltered areas like bays and harbours, adults often form schools near the seabed or around rocky reefs and rough bottoms. They are typically encountered at depths between 10 and 25 meters, though they have been recorded at depths exceeding 200 meters.

Feeding & Biology

As an opportunistic predator, the Silver Trevally feeds on a diverse diet that includes small fish, crustaceans, mollusks, worms, and echinoderms. They are also known to engage in suspension feeding, filtering plankton from the water column. These fish are strong swimmers, capable of reaching high speeds, and often exhibit seasonal movements between different coastal and pelagic habitats.
