Trevally
The silver trevally is also known as the giant trevally or leopard trevallies. The body is compressed and blue/green with yellow sides. There is a black spot on the operculum (hard flap over gills). Silver trevally usually feeds near the bottom on a variety of prey, including small fishes and crustaceans.
Silver trevally is typically found in coastal areas from estuaries to out to 40–60 m depth. Juveniles only occur shallowly. In Australia, silver trevally has been reported from south-western Western Australia, around the tropical north of Australia, and south to southern New South Wales.
Silver trevally is a predator with commercial significance. It is very common in its environment and not considered threatened. Silver trevally is an extremely fast-growing species and can live for over 30 years. The maximum length recorded was 45 cm total length (TL), but 60 cm TL is now believed to be an old record.
In New South Wales, silver trevally is restricted to the northern region because they can not tolerate warmer water below 26°C. Silver trevally has moderately elongate and compressed bodies. The upper body is bluish silver, with yellowish silver sides and a silver belly. There is a small black blotch on the operculum (the hard bony flap covering the gills). Silver trevally usually feeds near the bottom on a variety of prey, including small fishes and crustaceans.

Global trevally production
Trevally is highly valued for its delicious taste, and they are one of the most popular fish consumed globally. According to the Food and Agriculture Organization (FAO), trevally is the fourth most important fish in terms of global production, with a total catch of around 1.5 million tonnes in 2016. The vast majority of trevally are caught in the wild, with only a small amount being farmed.
Trevally is found in tropical and subtropical waters around the world, with the largest populations being in Southeast Asia and Oceania. They are often found near coral reefs and mangroves, where they feed on small fish and crustaceans.
Trevally is an important food fish in many parts of the world, and they are also popular as a sport fish due to their good fighting qualities. In some areas, such as Australia, trevally is considered to be a pest species due to its impact on native fish populations. As a result, there are strict regulations in place regarding their capture and sale.
