Lavender jobfishLRB

 
Pristipomoides sieboldii
23.6 cm TL

Characteristic features:

  • Dorsal and anal fins without scales basally
  • 69–74 lateral-line scales
  • Vomerine tooth patch with medial posterior extension
  • Total gill rakers on first gill arch 28–33

Colour:

Body silvery lavender, top of head with small dark spots, caudal fin purplish with pale margin.

Size:

Up to 65 cm TL.

Distribution:

Indo-West and Central Pacific in tropical waters.

Habitat:

Benthopelagic over rocky reefs, from 140 to at least 360 m depth.

Biology:

Feeds primarily on fishes, but also crustaceans, cephalopods and other benthic invertebrates. Maturity estimates of Lavender jobfish vary regionally. In the main Hawaiian Islands, length where 50% of females became mature was 23.8 cm FL, while in the north-western Hawaiian Islands, 50% of females became mature at 28.6 cm FL.1 Mean age at maturity was estimated at 2 years. Estimated mean maximum age is 8 years.2

Fisheries:

Caught mainly with bottom longlines and deep handlines.
