Silver Trevally, Pseudocaranx georgianus (Cuvier 1833)

More Info


Distribution

Found in southern Australia from north of Sydney, New South Wales, to just north of Perth, Western Australia. Elsewhere the species occurs in New Zealand. Inhabits coastal waters and bays, often near rocky areas, in depths of 0-200 m.

Features

Dorsal fin VIII + I, 25-28; Anal fin II; I, 21-24; Caudal fin 17; Pectoral fin 18-20; Pelvic fin I, 5; Lateral line 73-95 (scales) + 16-27 (scutes); Gill rakers 8-11 + 20-23.

Body deep, oval, compressed, tail base very slender; pectoral fins long, slender, scythe-like, reaching almost to straight part of lateral line; enlarged bony scales present at rear end of lateral line; hind margin of upper jaw nearly vertical; scales absent below and before eye.

Colour

Greenish-blue above, silvery below, with a rather large diffuse black spot on upper margin of gill cover; juveniles and subadults usually with a yellow mid-lateral stripe and a faint yellow stripe along dorsal and anal-fin bases.

Fisheries

The silver trevally is frequently sold in markets, especially in the Victorian region, and is considered to have a flesh of excellent flavour.

Remarks

Until 2006, this trevally was confused with the widely distributed anti-tropical species Pseudocaranx dentex (Bloch and Schneider). Smith-Vaniz & Jelks (2006) recognized P. georgianus as a valid species. It co-occurs with P. wrighti throughout most of its range except northwestern Australia where P. dinjerra occurs, and in Queensland and Lord Howe Island by what may be different species, tentatively identified as P. sp "dentex", which has more gill rakers among other characters.
