Seriolella bramaSnotty-nose trevally
Rounded silver-grey fish with a large black patch above the pectoral fin base. Schools of this trevalla are rare along the mainland coast, but occurred moderately commonly around the Tasmanian coast until the 1980s, although not often seen there now. Another member of the family, the silver warehou Seriolella punctata, also schools occasionally in shallow southern waters. That species has a more slender body, a series of dark spots along the middle of the sides, and dusky markings behind the eye.
Max Size: 76 cm
Sea Temperature Range: 11.4-19.8°C

Habitat Generalization Index: N/A
Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Infrequent (2.2% of sites)
Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed
Abundance: Many (66 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
