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.
