Crimson snapperLJT

 
Lutjanus erythropterus
32.7 cm TL

Characteristic features:

  • Longitudinal scale rows above lateral line obliquely positioned
  • Vomerine tooth patch lacking posterior extension
  • Preopercular notch indistinct
  • Mouth relatively small
  • Head profile sloped

Colour:

Pinkish red, paler on belly.

Size:

Up to 55 cm TL.

Distribution:

Indo-West Pacific in tropical waters.

Habitat:

Coral and rocky reefs, from the surface to at least 100 m depth.

Biology:

Feeds primarily on fishes, but also crustaceans, cephalopods and other benthic invertebrates. Usually occurs in small groups. In Australia length at first maturity is 28.8 cm SL and 24.0 cm SL for females and males, respectively. Length where 50% of individuals reach maturity was 35.1 cm SL and 26.8 cm SL for females and males, respectively. In eastern Indonesia spawning occurs throughout most of the year. Crimson snapper are a serial batch spawner and are highly fecund, producing an estimated 640,300 to 676,100 eggs in one spawning event.1 Estimated maximum age is 32 years on the Great Barrier Reef.2

Fisheries:

Caught mainly by handlines and trawls.

Lutjanus Marabaricus
Lutjanus malabaricus differ in having a larger mouth – maxilla length almost equal to distance between last dorsal- and anal-fin rays (vs. less); head profile more strongly humped (vs. straight) and caudal fin more truncate (vs. slightly emarginate).
