ANIMAL SPECIES:Tarwhine, Rhabdosargus sarba (Forsskål, 1775)
Tarwhine look a little like a deep-bodied bream with stripes. They are common on the New South Wales coast.
Identification
The Tarwhine can be recognised by its silver body with rows of yellow spots forming stripes. The pelvic and anal fins are usually yellow but fade with age.
The Tarwhine is sometimes confused with the Yellowfin Bream, Acanthopagrus australis, and the Black Bream Acanthopagrus butcheri. Both bream species lack the golden striped colouration of the Tarwhine. The Tarwhine also has a more rounded snout and a greater number of scale rows above the lateral line. There are 6-7 rows in the Tarwhine and 4 rows in the two bream species. Another distinguishing feature is the length of the third anal spine. In Tarwhines it is equal to the length of the second anal spine but shorter for the two Acanthopagrus.
Size range
It grows to 45 cm and weights up to 1.4 kg.Similar Species
