Characteristics.
Trevallies are actively swimming, highly
streamlined fishes with very fine scales.

ridge of plates on each side of the base
of the tail. Most species are silver in col-
our with some species having a blue or
gold colouration.
Size.
Maximum length for a Silver Trevally is approximately 1.4 m compared to the maximum length of Giant
Trevally that is around 1.7 m. The Larger Trevally species can grow up to 2 m and about 80 kg.
Distribution.
Trevally species are commonly found along the New South Wales Coast. The species more common in
NSW include the Silver Trevally, Bluefin Trevally and Bigeye Trevally. They are found on inshore reefs and
around estuary systems and can form large schools. Species such as Silver Trevally can be found in large
schools in offshore waters. At least 23 species of Trevally are found along the east coast of Australia.
