Rhabdosargus sarba, also known as the goldlined seabream, silver bream, tarwhine, or yellowfin bream, is a species of marine ray-finned fish belonging to the family Sparidae, which includes the seabreams and porgies. This fish has a wide Indo-Pacific distribution.

Taxonomy

Rhabdosargus sarba was first formally

monospecific genus Rhabdosargus. designating it as its type species.[3][6] S. auriventris is considered to be a junior synonyms of Gmelin's Sparus sarba.[3] The genus Rhabdosargus is placed in the family Sparidae within the order Spariformes by the 5th edition of Fishes of the World.[7] Some authorities classify this genus in the subfamily Sparinae,[8] but the 5th edition of Fishes of the World does not recognise subfamilies within the Sparidae.[7]

Etymology

Rhabdosargus sarba belongs to the genus Rhabdosargus, a name which is a refixes rhabdos, meaning "stick" or "rod", an allusion to the yellow abdominal band of Sargus auriventris, its type species, to Sargos, a name used for Sparid fish in ancient Greek at least as long ago as Aristotle but in this case is a reference to Sargus as a synonym of Diplodus. The specific name, sarba, is the Arabic name for this species in the Red Sea of Saudi Arabia.[9]

Description

Rhabdosargus sarba has a deep and compressed body, the body has a depth which fits into its

total length of 80 cm (31 in), although 45 cm (18 in) is more typical, and a maximum published weight of 12 kg (26 lb).[4]

Distribution and habitat

Rhabdosargus sarba has a wide Indo-Pacific distribution from the Red Sea and the eastern coast of Africa as far south as the southern coast of South Africa east across the Indian Ocean and into the Pacific Ocean as far as the South China Sea and Japan and south to Australia.[1] In Australia it is found along the Western Australian coast from Bremer Bay to Exmouth and along the east coast between Townsville, Queensland south to Mallacoota, Victoria.[11] There is a single records from the Mediterranean off Syria, and this is thought likely to have been a Lessepsian migrant from the Red Sea through the Suez Canal.[12] The tarwhine is found at depths between 0 and 60 m (0 and 197 ft),[4] juveniles and young fishes are found in estuaries but the adults move out to deeper coastal waters.[10]

Biology

Rhabdosargus sarba preys on benthic invertebrates, largely molluscs.

fork lengths of between 15 and 21 cm (5.9 and 8.3 in). Spawning occurs between July and November off KwaZulu-Natal in inshore waters, near large estuaries and river mouths. Off Western Australia goldlined seabream also spawns between July and November, spawning in batches. The age at when half the fish are sexually mature in KwaZulu-Natal is around 1.8 years and they change sex from male to female at between 1 and 2.5 years old. Goldlined seabreams have been observed moving into deeper, offshore waters to spawn.[1]

Fisheries

Rahbdosargus sabra is an important recreational angling species in Australia, although it is of minor importance as a commercial fishery target in southwestern Australia.[11] In South Africa and Mozambique this species is targeted by artisanal fishers[1] as well as being an important target for recreational anglers.[10] The goldlined seabream has been overfished in the Persian Gulf and the stock has declined so R. sarba has been classified by the International Union for Conservation of Natureas Near Threatened in the Persian Gulf,[2] while being classified as Least Concern globally.[1]
