Flame snapperETC

 
Etelis coruscans
30.1 cm TL

Characteristic features:

  • Dorsal fin deeply incised between spinous and soft portions
  • Maxilla with scales, maxilla extending to below mid-eye
  • 11 dorsal-fin soft rays
  • First gill arch with 23–28 gill rakers
  • Caudal fin deeply forked
  • Outer margin of operculum rounded

Note: Two morphs are present in this species – a long-tailed form and a short-tailed form. Both have been caught in waters around Fiji,
long-tailed forms found on seamounts and more commonly on island slopes, while short-tailed forms are usually restricted to seamounts only.1

Colour:

Deep pink to reddish.

Size:

Up to 120 cm TL.

Distribution:

Indo-West and Central Pacific in tropical and subtropical waters.

Habitat:

Rocky bottoms, from 90 to at least 400 m depth.

Biology:

Feeds primarily on small fishes, squid and crustaceans, and also planktonic organisms. Flame snapper are a slow growing, late maturing species. In waters off Hawaii females reached first maturity at 52.2 cm FL, length at which 50% of females reach maturity was 67.5–72.5 cm FL. In Tongan waters, age at maturity for both sexes combined was 4.1 years.2 In waters off Hawaii, spawning began in spring and summer (June/July) with multiple spawning events continuing until autumn or early winter, peaking in October.3 Estimated maximum age is 18 years.4

Fisheries:

Caught mainly with deep handlines.
