Lutjanus erythropterus

Osteichthyes Lutjanidae Genus Lutjanus Lutjanus erythropterus
Crimson snapper LJT
32.7 cm TL
Characteristic features:
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 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

Indonesian fisheries:

Caught mainly by handlines and trawls.
