Pristipomoides filamentosus

Osteichthyes Lutjanidae Genus Pristipomoides Pristipomoides filamentosus
Crimson jobfish PFM
20.2 cm TL
Characteristic features:
Colour:

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

Size:

Up to 100 cm TL.

Distribution:

Indo-West and Central Pacific in tropical waters.

Habitat:

Rocky reefs, from 40 to 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 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

Indonesian fisheries:

Caught mainly with handlines.
