Crimson jobfishPFM

 
Pristipomoides filamentosus
20.2 cm TL

Characteristic features:

  • Dorsal and anal fins without scales basally
  • 57–62 lateral-line scales
  • Total gill rakers on first gill arch 22–26

Colour:

Silvery brown to reddish purple, top of head with blue spots and narrow yellow lines, trailing edge of caudal fin yellowish.

Size:

To at least 100 cm TL.

Distribution:

Indo-West and Pacific in tropical waters.

Habitat:

Rocky reefs, from 40 to at least 360 m depth.

Biology:

Feeds primarily on fishes but also shrimps, crabs, ascidians and salps. Crimson jobfish undertake diurnal vertical migrations to their lower depth distributions at night to feed. Mean values of age and length at maturity are 3 years and 46.0 cm TL, respectively. Mean longevity is estimated at 13 years,1 however lead–radium and bomb radiocarbon dating of otoliths has estimated maximum age of up to at least 40 years.2

Fisheries:

Caught mainly with handlines.
